This 8 bit wide, active high strobe is active during the B2 PCM channel in ST-BUS mode. Forced to high impedance when LINEAR=1.Pin #Name DescriptionZL38010Data Sheet Functional DescriptionThe Quad-channel ADPCM Transcoder is a low power, CMOS device capable of four encode and four decode operations per frame. Four 64kbps channels (PCM octets) are compressed into four 32, 24 or 16kbps ADPCM channels (ADPCM words), and four 32, 24 or 16kbps ADPCM channels (ADPCM words) are expanded into four 64kbps PCM channels (PCM octets). The ADPCM transcoding algorithm utilized conforms to ITU-T recommendation G.726 (excluding 40kbps), and ANSI T1.303 - 1989. Switching on-the-fly between 32 and 24kbps transcoding is possible by toggling the appropriate mode select pins (supports T1 robbed-bit signalling). All functions supported by the device are pin selectable. The four encode functions comprise a common group controlled via Mode Select pins MS1, MS2 and MS3. Similarly, the four decode functions form a second group commonly controlled via Mode Select pins MS4, MS5 and MS6. All other pin controls are common to the entire transcoder.The device requires 6.5mWatts (MCLK= 4.096MHz) typically for four channel transcode operation. A minimum master clock frequency of 4.096MHz is required for the circuit to complete four encode channels and four decode channels per frame. For SSI operation a master clock frequency greater than 4.096MHz and asynchronous, relative to the 8kHz frame, is allowed.The PCM and ADPCM serial busses support both ST-BUS and Synchronous Serial Interface (SSI) operation. This allows serial data clock rates from 128kHz to 4096kHz, as well as compatibility with Zarlink’s standard Serial Telecom BUS (ST-BUS). For ST-BUS operation, on chip channel counters provide channel enable outputs as well as a 2048kHz bit clock output which may be used by down-stream devices utilizing the SSI bus interface.Linear coded PCM is also supported. In this mode the encoders compress, four 14-bit, two’s complement (S,S,S,12,...,1,0), uniform PCM channels into four 4, 3 or 2 bit ADPCM channels. Similarly, the decoder expands four 4, 3 or 2 bit ADPCM channels into four 16-bit, two’s complement (S,14,...,1,0), uniform PCM channels. The data rate for both ST-BUS and SSI operation in this mode is 2048 kbps.ZL38010Data Sheet Serial (AD)PCM Data I/OSerial data transfer to/from the Quad ADPCM transcoder is provided through one ADPCM and two PCM ports (ADPCMi, ADPCMo, PCMi1, PCMo1, PCMi2, PCMo2). Data is transferred through these ports according to either ST-BUS or SSI requirements. The device determines the mode of operation by monitoring the signal applied to the F0i pin. When a valid ST-BUS frame pulse (244nSec low going pulse) is applied to the F0i pin the transcoder will assume ST-BUS operation. If F0i is tied continuously to V SS the transcoder will assume SSI operation. Pin functionality in each of these modes is described in the following sub-sections.ST-BUS ModeDuring ST-BUS operation the C2o, EN1, EN2 and F0od outputs become active and all serial timing is derived from the MCLK (C4) and F0i inputs while the BCLK input is tied to V SS. (See Figures 7, 8 & 9.)Basic Rate “D” and “C” ChannelsIn ST-BUS mode, when ENB1 is brought low, transparent transport of the ST-BUS "Basic Rate D- and C-channels" is supported through the PCMi1 and PCMo1 pins. This allows a microprocessor controlled device, connected to the PCMi/o1 pins, to access the "D" and "C" channels of a transmission device connected to the ADPCMi/o pins. When ENB1 is brought high, the “D” and “C” channel outputs are tristated. Basic Rate “D” and “C” channels are not supported in LINEAR mode.(See Figure 7.)SSI ModeDuring SSI operation the BCLK, ENB1 and ENB2/F0od inputs become active. The C2o, EN1, and EN2 outputs are forced to a high-impedance state except during LINEAR operation during which the EN1 output remains active. (See Figures 4, 5 & 6.)The SSI port is a serial data interface, including data input and data output pins, a variable rate bit clock input and two input strobes providing enables for data transfers. There are three SSI I/O ports on the Quad ADPCM; the PCMi/o1 PCM port, the PCMi/o2 PCM port, and the ADPCMi/o port. The two PCM ports may transport 8-bit companded PCM or 16-bit linear PCM. The alignment of the channels is determined by the two input strobe signals ENB1 and ENB2/F0od. The bit clock (BCLK) and input strobes (ENB1 and ENB2/F0od) are common for all three of the serial I/O ports. BCLK can be any frequency between 128kHz and 4096kHz synchronized to the input strobes. BCLK may be discontinuous outside of the strobe boundaries except when LINEAR=1. In LINEAR mode, BCLK must be 2048kHz and continuous for 64 cycles after the ENB1 rising edge and for the duration of ENB2/F0od. Mode Select Operation (MS1, MS2, MS3, MS4, MS5, MS6)Mode Select pins MS1, MS2 and MS3 program different bit rate ADPCM coding, bypass, algorithmic reset and disable modes for all four encoder functions simultaneously. When 24kbps ADPCM mode is selected bit 4 is unused while in 16kbps ADPCM mode all ADPCM channels are packed contiguously into one 8-bit octet. Mode Select pins MS4, MS5 and MS6 operate in the same manner for the four decode functions. The mode selects must be set up according to the timing constraints illustrated in Figures 16 and 17.32 kbps ADPCM ModeIn 32kbps ADPCM mode, the 8-bit PCM octets of the B1, B2, B3 and B4 channels (PCMi1 and PCMi2) are compressed into four 4-bit ADPCM words on ADPCMo. Conversely, the 4-bit ADPCM words of the B1, B2, B3 and B4 channels from ADPCMi are expanded into four 8-bit PCM octets on PCMo1 and PCMo2. The 8-bit PCM octets (A-Law or µ-Law) are transferred most significant bit first starting with b7 and ending with b0. ADPCM words are transferred most significant bit first starting with I1 and ending with I4 (See Figures 4 & 7). Reference ITU-T G.726 for I-bit definitions.ZL38010Data Sheet24 kbps ADPCM ModeIn 24kbps mode PCM octets are transcoded into 3-bit words rather than the 4-bit words utilized in 32kbps ADPCM. This is useful in situations where lower bandwidth transmission is required. Dynamic operation of the mode select control pins will allow switching from 32kbps mode to 24kbps mode on a frame by frame basis. The 8 bit PCM octets (A-Law or µ-Law) are transferred most significant bit first starting with b7 and ending with b0. ADPCM words are transferred most significant bit first starting with I1 and ending with I3 (I4 becomes don’t care). (See Figures 4 & 7.)16 kbps ADPCM ModeWhen SEL is set to 0, the 8-bit PCM octets of the B1, B2, B3 and B4 channels (PCMi1 and PCMi2) are compressed into four 2-bit ADPCM words on ADPCMo during the ENB1 timeslot in SSI mode and during the B1 timeslot in ST-BUS mode. Similarly, the four 2-bit ADPCM words on ADPCMi are expanded into four 8-bit PCM octets (on PCMo1 and PCMo2) during the ENB1/B1 timeslot. (See Figures 4 & 7.)When SEL is set to 1, The same conversion takes place as described when SEL = 0 except that the ENB2/B2 timeslots are utilized.A-Law or µ-Law 8-bit PCM are received and transmitted most significant bit first starting with b7 and ending with b0. ADPCM data are most significant bit first starting with I1 and ending with I2.ADPCM BYPASS (32 and 24 kbps)In ADPCM bypass mode the B1 and B2 channel ADPCM words are bypassed (with a two-frame delay) to/from the ADPCM port and placed into the most significant nibbles of the PCM1/2 port octets. Note that the SEL pin performs no function for these two modes (See Figures 6 & 9). LINEAR, FORMAT and A/µ pins are ignored in bypass mode. In 32kbps ADPCM bypass mode, Bits 1 to 4 of the B1, B2, B3 and B4 channels from PCMi1 and PCMi2 are transparently passed, with a two frame delay, to the same channels on ADPCMo. In the same manner, the B1, B2, B3 and B4 channels from ADPCMi are transparently passed, with a two frame delay, to the same channels on PCMo1 and PCMo2 pins. Bits 5 to 8 are don’t care. This feature allows two voice terminals, which utilize ADPCM transcoding, to communicate through a system without incurring unnecessary transcode conversions. This arrangement allows byte-wide or nibble-wide transport through a switching matrix.24kbps ADPCM bypass mode is the same as 32 kbps mode bypass excepting that only bits 1 to 3 are bypassed and bits 4 to 8 are don’t care.ADPCM BYPASS (16 kbps)When SEL is set to 0, only bits 1 and 2 of the B1, B2, B3 and B4 PCM octets (on PCMi1 and PCMi2) are bypassed, with a two frame delay, to the same channels on ADPCMo during the ENB1 timeslot in SSI mode and during the B1 timeslot in ST-BUS mode. Similarly, the four 2-bit ADPCM words on ADPCMi are transparently bypassed, with a two frame delay, to PCMo1 and PCMo2 during the ENB1 or B1 timeslot. Bits 3-8 are don’t care. (See Figures 6 & 9.)When SEL is set to 1, the same bypass occurs as described when SEL = 0 except that the ENB2 or B2 timeslots are utilized.LINEAR, FORMAT and A/µ pins are ignored in bypass mode.ZL38010Data SheetPCM BYPASSWhen SEL is set to 0, the B1 and B2 PCM channels on PCMi1 are transparently passed, with a two-frame delay, to the same channels on the ADPCMo. Summarily, the two 8-bit words which are on ADPCMi are transparently passed, with a two-frame delay, to channels B1 and B2 of PCMo1 while PCMo2 is set to a high-impedance state.(See Figures 6 & 9.)When SEL is set to 1, the B3 and B4 channels on PCMi2 are transparently passed, with a two frame delay, to the same channels on ADPCMo. Similarly, the two 8-bit words which are on ADPCMi are transparently passed, with a two-frame delay, to channels B3 and B4 of PCMo2. In this case PCMo1 is always high-impedance if ENB1 = 0. If ENB1 = 1 during ST-BUS operation then the D and C channels are active on PCMo1.LINEAR, FORMAT and A/µ pins are ignored in bypass mode.Algorithm Reset ModeWhile an algorithmic reset is asserted the device will incrementally converge its internal variables to the 'Optional reset values' stated in G.726. Algorithmic reset requires that the master clock (MCLK) and frame pulse (ENB1/2 or F0i) remain active and that the reset condition be valid for at least four frames. Note that this is not a power down mode; see PWRDN for this function.ADPCMo & PCMo1/2 DisableWhen the encoders are programmed for ADPCMo disable (MS1 to MS3 set to 1) the ADPCMo output is set to a high impedance state and the internal encode function remains active. Therefore convergence is maintained. The decode processing function and data I/O remain active.When the decoders are programmed for PCMo1/2 disable (MS4 to MS6 set to 1) the PCMo1/2 outputs are high impedance during the B Channel timeslots and also, during ST-BUS operation, the D and C channel timeslots according to the state of ENB1. Therefore convergence is maintained. The encode processing function and data I/O remain active.Whenever any combination of the encoders or decoders are set to the disable mode the following outputs remain active. A) ST-BUS mode: ENB2/F0od, EN1, EN2 and C2o. Also the “D” and “C” channels from PCMo1 and ADPCMo remain active if ENB1 is set to 0. If ENB1 is brought high then PCMo1 and ADPCMo are fully tri-stated. B) SSI mode: When used in the 16-bit linear mode, only the EN1 output remains active. For complete chip power down see PWRDN.ZL38010Data Sheet Other Pin Controls16 Bit Linear PCMSetting the LINEAR pin to logic one causes the device to change to 16-bit linear (uniform) PCM transmission on the PCMi/o1 and PCMi/o2 ports. The data rate for both ST-BUS and SSI operation in this mode is 2048 kbps and all decode and encode functions are affected by this pin. In SSI mode, the input channel strobes ENB1 and ENB2/F0od remain active for 8 cycles of BCLK for an ADPCM transfer. The EN1 output is high for one BCLK period at the end of the frame (i.e., during the 256th BCLK period). In ST-BUS mode, the output strobes EN1 and ENB2/F0od are adjusted to accommodate the required PCM I/O streams. The EN1 output becomes a single bit high true pulse during the last clock period of the frame (i.e., the 256th bit period) while ENB2/F0od becomes a delayed, low true frame-pulse (F0od) output occurring during the 64th bit period after the EN1 rising edge.Linear PCM on PCMi1 and PCMi2, are received as 14-bit, two’s complement data with three bits of sign extension in the most significant positions (i.e., S,S,S,12,...1,0) for a total of 16 bits. The linear PCM data transmitted from PCMo1 and PCmo2 are 16-bit, two’s complement data with one sign bit in the most significant position (i.e., S,14,13,...1,0)32 and 24 kbps ADPCM modeIn 32kbps and 24kbps linear mode, the 16-bit uniform PCM dual-octets of the B1, B2, B3 and B4 channels (from PCMi1 and PCMi2) are compressed into four 4-bit words on ADPCMo. The four 4-bit ADPCM words of the B1, B2, B3 and B4 channels from ADPCMi are expanded into four 16-bit uniform PCM dual-octets on PCMo1 and PCMo2. 16-bit uniform PCM are received and transmitted most significant bit first starting with b15 and ending with b0. ADPCM data are transferred most significant bit first starting with I1 and ending with I4 for 32kbps and ending with I3 for 24kbps operation (i.e., I4 is don’t care).(See Figures 5 & 8.)16 kbps ADPCM modeWhen SEL is set to 0, the four, 2-bit ADPCM words are transmitted/received on ADPCMo/i during the ENB1 time-slot in SSI mode and during the B1 timeslot in ST-BUS mode. When SEL is set to 1, the four, 2-bit ADPCM words are transmitted/received on ADPCMo/i during the ENB2 timeslot in SSI mode and during the B2 timeslot in ST-BUS mode. (See Figures 5 & 8.)PCM Law Control (A/µ, FORMAT)The PCM companding/coding law invoked by the transcoder is controlled via the A/µ and FORMAT pins. ITU-T G.711 companding curves, µ-Law and A-Law, are selected by the A/µ pin (0=µ-Law; 1=A-Law). Per sample, digital code assignment can conform to ITU-T G.711 (when FORMAT=1) or to Sign-Magnitude coding (when FORMAT=0). Table 1 illustrates these choices.ZL38010Data SheetTable 1 - Companded PCMPower DownSetting the PWRDN pin low will asynchronously cause all internal operation to halt and the device to go to a power down condition where no internal clocks are running. Output pins C2o, EN1, EN2, PCMo1, PCMo2 and ADPCMo and I/O pin F0od/ENB2 are forced to a high-impedance state. Following the reset (i.e., PWRDN pin brought high)and assuming that clocks are applied to the MCLK and BCLK pins, the internal clocks will still not begin to operate until the first frame alignment is detected on the ENB1 pin for SSI mode or on the F0i pin for ST-BUS mode. The C2o clock and EN1, EN2 pins will not start operation until a valid frame pulse is applied to the F0i pin. If the F0i pin remains low for longer than 2 cycles of MCLK then the C2o pin will top toggling and will stay low. If the F0i pin is held high then the C2o pin will continue to operate. In ST-BUS mode the EN1 and EN2 pins will stop toggling if the frame pulse (F0i) is not applied every frame.Master Clock (MCLK)A minimum 4096kHz master clock is required for execution of the transcoding algorithm. The algorithm requires 512 cycles of MCLK during one frame for proper operation. For SSI operation this input, at the MCLK pin, may be asynchronous with the 8kHz frame provided that the lowest frequency and deviation due to clock jitter still meets the strobe period requirement of a minimum of 512 t C4P - 25%t C4P (see Figure 3). For example, a system producing large jitter values can be accommodated by running an over-speed MCLK that will ensure a minimum 512 MCLK cycles per frame is obtained. The minimum MCLK period is 61nSec, which translates to a maximum frequency of 16.384MHz. Extra MCLK cycles (>512/frame) are acceptable since the transcoder is aligned by the appropriate strobe signals each frame.Figure 3 - MCLK Minimum RequirementFORMAT01PCM CodeSign-Magnitude A/µ = 0 or 1ITU-T (G.711)(A/µ = 0)(A/µ = 1)+ Full Scale 1111 11111000 00001010 1010+ Zero 1000 00001111 11111101 0101- Zero 0000 00000111 11110101 0101- Full Scale0111 11110000 00000010 1010ENB1MCLK512 t C4P - 25%t C4P MinimumZL38010Data Sheet Bit Clock (BCLK)For SSI operation the bit rate, for both ADPCM and PCM ports, is determined by the clock input at BCLK. BCLK must be eight periods in duration and synchronous with the 8kHz frame inputs at ENB1 and ENB2. Data is sampled at PCMi1/2 and at ADPCMi concurrent with the falling edge of BCLK. Data is available at PCMo1/2 and ADPCMo concurrent with the rising edge of BCLK. BCLK may be any rate between 128kHz and 4096kHz. For ST-BUS operation BCLK is ignored (tie to V SS) and the bit rate is internally set to 2048kbps.Figure 4 - SSI 8-Bit Companded PCM Relative TimingZL38010Data SheetFigure 5 - SSI 16-Bit Linear PCM Relative TimingZL38010Data SheetFigure 6 - SSI PCM and ADPCM Bypass Relative TimingZL38010Data SheetFigure 7 - ST-BUS 8-Bit Companded PCM Relative TimingZL38010Data SheetFigure 8 - ST-BUS 16-Bit Linear PCM Relative TimingZL38010Data SheetFigure 9 - ST-BUS PCM and ADPCM Bypass Relative TimingZL38010Data Sheet Processing Delay Through the DeviceIn order to accommodate variable rate PCM and ADPCM interfaces, the serial input and output streams require a complete frame to load internal shift registers. Internal frame alignment of the encoding/decoding functions are taken from either of the F0i or ENB1 & ENB2 input strobes depending upon the device operating mode (i.e., ST-BUS or SSI). The encoding/decoding of all channels then takes one frame to complete before the output buffers are loaded. This results in a two frame transcoding delay. The two frame delay also applies to the D and C channels and to the PCM and ADPCM bypass functions.(See Figure 10.)Note: When changing the relative positions of the ENB1 and ENB2 strobes, precaution must be taken to ensure that two conditions are met. They are:1.There must be at least 512 master clock cycles between consecutive rising edges of ENB1. This condition alsoholds true for ENB2.2.The ENB1 strobe must alternate with the ENB2 strobe.Violation of these requirements may cause noise on the output channels.Figure 10 - Data ThroughputApplicationsFigure 11 depicts an ISDN line card utilizing a ’U’ interface transceiver and ZL38010 ADPCM transcoder.

A functional block diagram is shown in Figure 1.This device is ideally suited for designs that require both a transmit timing path (backplane to PHY) and a receive timing path (PHY to backplane). Each path is controlled with separate DPLLs (Tx DPLL, Rx DPLL) which are both independently configurable through the serial interface (SPI or I2C). A typical application of the ZL30131 is shown in Figure 2. In this application, the ZL30131 translates the 19.44MHz clock from the telecom rate backplane (system timing bus), translates the frequency to 622.08MHz or 156.25MHz for the PHY Tx clock, and filters the jitter to ensure compliance with the related standards. A programmable synthesizer (P0) provides synchronous PDH clocks with multiples of 8kHz for generating PDH interface clocks. On the receive path, the Rx DPLL and the P1 synthesizer translate the line recovered clock (8kHz or 25MHz) from the PHY to the 19.44MHz telecom backplane (line recovered timing) for the central timing cards. The ZL30131 allows easy integration of Ethernet line rates with today’s telecom backplanes.Figure 2 - Typical Application of the ZL30131Information relating to products and services furnished herein by Zarlink Semiconductor Inc. or its subsidiaries (collectively “Zarlink”) is believed to be reliable.However, Zarlink assumes no liability for errors that may appear in this publication, or for liability otherwise arising from the application or use of any such information, product or service or for any infringement of patents or other intellectual property rights owned by third parties which may result from such application or use.

The ZL38003 provides 127ms of acoustic echo cancellation, which makes it ideal for hand free car kits, and speaker phones designs.Each of the codecs in the dual codec can be connected to 1 of 4 four analog ports through a cross point switch.Also, the network side can be routed to a digital PCM interface that input/outputs either linear 2's complement or A-/mu law commanded PCM data.MT93L16ZL38001ZL38002ZL38003Description AEC for analog hands-free communicationAEC for analog hands-free communication AEC with noise reduction for digital hands-free communicationAEC with noise reduction & codecs for digital hands-free communicationApplication Analog Desktop phone Analog Intercom Analog Desktop phone Analog Intercom Hands-free Car KitsDigital Desktop Phone Home Security Intercom & Pedestals Hands-free Car Kits Digital Desktop Phone Home SecurityIntercom & Pedestals Features AEC 1 channel 1 channel 1 channel 1 channel LEC 1 channel 1 channel Custom LoadCustom LoadGains User GainUser Gain/18dB Gain on SoutUser Gain + System tuning gainsUser Gain + System tuning gainsNoiseReduction N N Y Y Integrated CodecsNNNdual channelTable 1 - Acoustic Echo Cancellation Family2.0 Acoustic Echo Canceller (AEC) DescriptionThe AEC section is comprised of an acoustic echo canceller, noise reduction and the operational control functions for operation. The AEC guarantees clear signal transmission in both transmit and receive audio path directions ensuring reliable voice communication even when low level signals are provided. The AEC does not use variable attenuators during double-talk or single-talk periods of speech, as do many other acoustic echo cancellers for speakerphones. Instead, the AEC provides high performance full-duplex operation similar to network echo cancellers. This results in users experiencing clear speech and uninterrupted background signals during the conversation and prevents subjective sound quality problems associated with “noise gating” or “noise contrasting”.The AEC uses an advanced adaptive filter algorithm that is double-talk stable, allowing convergence even while both parties are talking. This algorithm continually tracks changes in the echo path, regardless of double-talk, as long as a reference signal is available for the echo canceller.The echo tail cancellation capability of the acoustic echo canceller has been sized appropriately (127ms) to cancel echo in an average sized office or large size car with a reverberation time of less than 127ms.Figure 2 - AEC Block DiagramRoutSinMicro InterfaceProgram RAM Program ROMHowling ControllerNBSDLinear/µ/A-LawR 1R 1S 1S 2L inear/µ/A-LawHP Filter Linearµ/A-Law/Adaptive FilterHP FilterSoutRinAGCUser Gain +--24 -> +21dBADV NLPLinearµ/A-Law/+UNIT CONTROL DetectorTalk Double NBSDLimiterLimiterA C O U S T I C E C H O P A T HGain PadGain PadGain Pad Noise Reduction2.1 In addition to the echo cancellers, the following functions are supported:•12dB of noise reduction•User gain control provided for speaker path (-24dB to +21dB in 3dB steps)•Gain pads at the Sin and Sout ports plus one at the input of adaptive filter (XRAM)•Control of adaptive filter convergence speed during periods of double-talk, far end single-talk and near-end echo path changes•Control of Non-Linear Processor thresholds for suppression of residual non-linear echo•Howling detector to identify when instability is starting to occur and to take action to prevent oscillation •Narrow-Band Detector for preventing adaptive filter divergence caused by narrow-band signals •Programmable high pass filters at Rin and Sin for removal of DC components in PCM channels•Limiters that introduce controlled saturation levels•Serial controller interface compatible with Motorola, National and Intel micro controllers•PCM encoder/decoder compatible with m/A-Law ITU-T G.711, m/A-Law Sign-Mag or linear 2’s complement coding•Automatic gain control on the receive speaker path•Idle channel noise suppression3.0 Dual Codec DescriptionThe CODEC Dual Codec provides complete audio to PCM interfaces including filtering and optional data companding as required by the ITU-T G.711 & G.712 recommendations. Programmable gain allows adjustment for a wide range of transducer sensitivities - two microphone amplifiers and four ear piece amplifiers are provided to allow connection to a handset, headset, auxiliary channel and microphone/speaker. A cross-point circuit allows either codec to be connected to any of the four audio interfaces. Programmable voltage sources are available for electret biasing on the Microphone channels.PCM voice data is passed via a serial interface which operates in ST-BUS or GCI mode. ST-BUS mode allows the Codecs to be allocated to any of the 32 available channels. Control and programming of the Codecs is carried out over a flexible serial micro-controller interface.Figure 3 - Block DiagramInformation relating to products and services furnished herein by Zarlink Semiconductor Inc. or its subsidiaries (collectively “Zarlink”) is believed to be reliable.However, Zarlink assumes no liability for errors that may appear in this publication, or for liability otherwise arising from the application or use of any such information, product or service or for any infringement of patents or other intellectual property rights owned by third parties which may result from such application or use.

This error signal is passed to the Loop Filter circuit.1.2 Lock IndicatorThe ZL30414 has a built-in LOCK detector that measures frequency difference between input reference clock C19i and the VCO frequency. When the VCO frequency is less than ±300ppm apart from the input reference frequency then the LOCK pin is set high. The LOCK pin is pulled low if the frequency difference exceeds ±1000ppm.1.3 Loop FilterThe Loop Filter is a low pass filter. This low pass filter ensures that the network jitter requirements are met for an input reference frequency of 19.44MHz. The corner frequency of the Loop Filter is configurable with an external capacitor and resistor connected to the LPF pin and ground as shown in Figure 3.Figure 3 - Loop Filter Elements60GND Ground. 0 volt61VCC Positive Analog Power Supply. +3.3V ±10%.6263C622oP-A C622oN-A C622 Clock Output (LVPECL).

The VCO output is connected to the "Frequency Dividers and Clock Drivers" block that divides VCO frequency and buffer generated clocks.1.5 Output Interface CircuitThe output of the VCO is used by the Output Interface Circuit to provide four LVPECL differential clocks at 622.08MHz, one CML differential clock at 155.52MHz and a single-ended 19.44MHz output clock. This block provides also a 19.44MHz feedback clock that closes PLL loop. Each output clock can be enabled or disabled individually with the associated Output Enable pin.Output Clocks Output Enable PinsC622oP/N-A C622oEN-AC622oP/N-B C622oEN-BC622oP/N-C C622oEN-CC622oP/N-D C622oEN-DC155oP/N C155oENC19o C19oENTable 1 - Output Enable ControlTo reduce power consumption and achieve the lowest possible intrinsic jitter the unused output clocks must be disabled. If any of the LVPECL outputs are disabled they must be left open without any terminations.ZL30414Data Sheet 2.0 ZL30414 PerformanceThe following are some of the ZL30414 performance indicators that complement results listed in the Characteristics section of this data sheet.2.1 Input Jitter ToleranceJitter tolerance is a measure of the PLL’s ability to operate properly (i.e., remain in lock and/or regain lock in the presence of large jitter magnitudes at various jitter frequencies) when jitter is applied to its input reference. The input jitter tolerance of the ZL30414 is shown in Figure 4. On this graph, the single line at the top represents measured input jitter tolerance and the three overlapping lines below represent minimum input jitter tolerance for OC-192, OC-48, and OC-12 network interfaces. The jitter tolerance is expressed in picoseconds (pk-pk) to accommodate requirements for interfaces operating at different rates.Figure 4 - Input Jitter ToleranceZL30414Data Sheet 2.2 Jitter Transfer CharacteristicJitter Transfer Characteristic represents a ratio of the jitter at the output of a PLL to the jitter applied to the input of a PLL. This ratio is expressed in dB and it characterizes the PLLs ability to attenuate (filter) jitter. The jitter transfer characteristic for the ZL30414 configured with recommended loop filter components (R F=8.2 kΩ, C F=470 nF) is shown in Figure 5. The plotted curves represent jitter transfer characteristics over the recommended voltage (3.0V to 3.6V) and temperature (-40C to 85C) ranges.Figure 5 - Jitter Transfer CharacteristicZL30414Data Sheet3.0 Applications3.1 Ultra-Low Jitter SONET/SDH Equipment ClocksThe ZL30414 functionality and performance complements the entire family of the Zarlink’s advanced network synchronization PLLs. Its superior jitter filtering characteristics exceed requirements of SONET/SDH optical interfaces operating up to OC-192/STM-64 rate (10 Gbit/s). The ZL30414 in combination with the MT90401 or the ZL30407 (SONET/SDH Network Element PLLs) provides the core building blocks for high quality equipment clocks suitable for network synchronization (see Figure 6) .Figure 6 - SONET/SDH Equipment ClockMT90401ZL30414C155o CML622.08 MHz 19.44 MHzC622oA LVPECL C622oB LVPECLC622oC LVPECL C622oD LVPECL C19o CMOSC19iC19o CMOS C155o LVDS C34o/C44o CMOS C16o CMOS C8o CMOS C6o CMOS 19.44 MHz C2o CMOS C1.5o CMOS F8o CMOS F0o CMOS622.08 MHz 622.08 MHz 622.08 MHz 155.52 MHzC4o CMOS 34.368 MHz or 44.736 MHz 16.384 MHz 8.192 MHz 6.312 MHz 4.096 MHz 2.048 MHz 1.544 MHz 8 kHz 8 kHzPRI SECPRIOR SECOR LOCKHOLDOVERRefSel RefAlignR FLPFC FC 155o E N155.52 MHz C 622o E N -AC 622o E N -BC 622o E N -CC 622o E N -DC 19o E ND SC SR /WA 0 - A 6D 0 - D 7uPData PortController PortSynchronization Reference ClocksNote: Only main functional connections are shown20 MHz C 20iF16o CMOS OCXO8 kHz or ZL30407L O C KZL30414Data SheetThe ZL30414 in combination with the MT9046 provides an optimum solution for SONET/SDH line cards (see Figure 7).Figure 7 - SONET/SDH Line CardMT9046ZL30414C19iC19o CMOS C16o CMOS C8o CMOS C6o CMOS 19.44 MHz C2o CMOS C1.5o CMOS F8o CMOS F0o CMOSC4o CMOS16.384 MHz 8.192 MHz 6.312 MHz 4.096 MHz 2.048 MHz 1.544 MHz 8 kHz 8 kHzPRI SECLOCKHOLDOVERRSELR 1LPFC 1C 155o E NC 622o E N -AC 622o E N -BC 622o E N -CC 622o E N -DC 19o E NM S 1F S 2F L O C KuCSynchronization Reference ClocksNote: Only main functional connections are shown20 MHz F16o CMOS TCXO8 kHz C 2R 1 = 680 ΩC 1 = 820 nF C 2 = 22 nFC20iM S 2F S 1P C C iHardware ControlT C L RC155o CML622.08 MHz 19.44 MHzC622oA LVPECL C622oB LVPECLC622oC LVPECLC622oD LVPECL C19o CMOS622.08 MHz 622.08 MHz 622.08 MHz 155.52 MHz L O C KZL30414Data Sheet3.2 Recommended Interface circuit 3.2.1 LVPECL to LVPECL InterfaceThe C622oP/N-A, C622oP/N-B, C622oP/N-B, and C622oP/N-D outputs provide differential LVPECL clocks at 622.08MHz. The LVPECL output drivers require a 50Ω termination connected to the Vcc-2V source for each output terminal at the terminating end as shown below. The terminating resistors should be placed as close as possible to the LVPECL receiver.Figure 8 - LVPECL to LVPECL Interface3.2.2 CML to CML InterfaceThe C155o output provides a differential CML/LVDS compatible clock at 155.52MHz.

The standard specifies the V CM (common mode voltage)as minimum 1.125V, typical 1.2V, and maximum 1.375V. The following figure provides a recommendation for LVDS applications.Figure 10 - LVDS Termination3.2.4 CML to LVPECL InterfaceThe CML output can drive LVPECL input as is shown in Figure 11.

In the case where fewer than four clocks are required, a user can disable unused LVPECL outputs on the ZL30414 by pulling the corresponding enable pins low.When disabled, voltage at the both pins of the differential LVPECL output will be pulled up to Vcc - 0.7V.For applications requiring the LVPECL outputs to be in a tri-state mode, external AC coupling can be used as shown in Figure 12. Typically this might be required in hot swappable applications.Resistors R1 and R2 are required for DC bias of the LVPECL driver. Capacitors C1 and C2 are used as AC coupling capacitors. During disable mode (C622oEN pin pulled low) those capacitors present infinite impedance to the DC signal and to the receiving device this looks like a tristated (High-Z) output. Resistors R3, R4, R5 and R6are used to terminate the transmission line with 50ohm impedance and to generate DC bias voltage for the LVPECL receiver. If the LVPECL receiver has an integrated 50ohm termination and bias source, resistors R3, R4,R5 and R6 should not be populated.Figure 12 - Tristatable LVPECL OutputsZ=50Z=50C622oENZL304140.1 uC10.1 uC2R482.5R682.5R5127R3127R1200R2200 3.3 V 3.3 VZL30414Data Sheet 3.4 Power Supply and BIAS Circuit Filtering RecommendationsFigure 13 presents a complete filtering arrangement that is recommended for applications requiring maximum jitter performance.

These applications are resident in external memory and are down-loaded by the ZL38005 resident boot code during initialization.The firmware product and manual available at the release of this data sheet is the ZLS38501: Acoustic Echo Canceller with Noise Reduction. If these applications do not meet your requirements, please contact your local Zarlink Sales Office for the latest firmware releases.The ZL38005 Advanced Acoustic Echo Canceller with Noise Reduction platform integrates Zarlink’s Voice Processor (ZVP) DSP Core with a number of internal peripherals. These peripherals include the following:•Two independent ∆Σ CODECs•Two PCM ports - ST BUS, GCI, McBSP or SSI operation•An I2S interface port• A 2048 tap Filter Co-processor (LMS, FIR and FAP realizations)•Two Auxiliary Timers and a Watchdog Timer•11 GPIO pins• A UART interface• A Slave SPI port and a Master SPI port• A timing block that supports master and slave operation•An IEEE - 1149.1 compatible JTAG portThe DSP Core can process up to four 8-bit audio channels, two 16-bit audio channels or two 8-bit and one 16-bit audio channel. These audio channels may originate and terminate with the Σ∆ CODECs, or be communicated to and from the DSP Core through the PCM ports or the I2S port.ZL38005Data Sheet2.0 Core DSP Functional BlockThe ZL38005 DSP Core functional block, illustrated in Figure 1, is made up of a DSP Core, Interrupt Controller, Data RAM, Instruction RAM, BOOT ROM Hardware Accelerators. This block controls the timing (APLL and Timing Generator), peripheral interfaces through a peripheral address/data/control bus.The ZL38005 implementation of DSP core and Filter Co-processor have been optimized to efficiently support voice processing applications. These applications are described in detail in the Firmware Manuals associated with this hardware platform.2.1 DSPThe Core DSP is a 100 MIPS processor realized with two internal memory busses (Harvard architecture) to allow multiple accesses during the same instruction cycle. In addition the DSP uses hardware accelerators and a filter co processor that can be reused for different applications.The Filter Co-Processor is used by the application firmware to realize the LMS filters up to a maximum of 2048 coefficients (taps).3.0 Codec[1:0]The ZL38005 has two 16-bit fully differential ∆Σ DACs (DAC 0/1) that meets G.712 requirements at 8kHz sampling The ADC path consists of input signal pins C0/1_ADCi+ and C0/1_ADCi- (buffer output pins C0/1_BF0+ and C0/1_BFo-), which feed selectable Microphone Amplifier or Line Amplifier options. The ADC sampling is 8KHz.4.0 PCM Port4.1 PCM PortThe PCM port support data communication between an external peripheral device and the ZL38005 DSP Core using separate input (PCMi) and output (PCMo) serial streams with TDM (i.e., ST-BUS, GCI or McBSP) or SSI interface timing. Access to the control and status registers associated with these ports is through the Slave SPI port UART. These port signals are either in their input or high impedance states after a power-on reset and outputs signals PCMo may be put in a high impedance state at any time during normal operation. Refer to the associated Firmware Manual for PCM port control, status and mode selection.Figure 2 illustrates the signals associated with the Master and Slave timing modes of operation for PCM Port. Insert A: PCM port Master TDM (Mode 0), shows data clock (PCM_CLKo) and frame pulse (PCMFP) as outputs derived from the ZL38005 internal PLL. PCM_CLKo clocks data into the ZL38005 on PCMCMi and out of the ZL38005 on PCMo, and PCMFP delineates the 8kHz frame boundaries for these signals. Insert B: PCM Master SSI (Mode3), functions the same way as the TDM Master except that selected channels are defined by enable outputs P0ENA1 and P0ENA2.With slave operation the source of timing is not the ZL38005, so PCM_CLKi is the input clock and PCMFP is the 8kHz input frame pulse. This is illustrated by Figure 2 C: PCM Port Slave TDM (Modes 1 & 2) and D: PCM Port Slave SSI (Modes 4, 5 & 6).ZL38005Data SheetFigure 2 - PCM Port Signal Configurations for Master/Slave OperationThe ZL38005 will process audio channels of up to 16 bits in length. Audio channel sizes are designated as either 8-bit (Short) or 16-bit (Long) on the PCM interfaces. With TDM operation each audio channel is mapped on to one or more 8-bit time slots that are defined by the associated frame alignment signal. Each PCM port (0 & 1) supports from 1 to 4 Short Channels; 1 or 2 Short Channels and 1 Long (16-bit) Channel; or 2 Long Channels. Audio channels are defined as First and Second Long, and First, Second, Third and Fourth Short, see the Firmware Manual for assignment details. These channels may be assigned to different time slots on the input and output streams.In SSI mode each PCM port supports 1 or 2 Short or Long channels, which are defined on PCMi0 by the position and length of enable signals P0ENA1 and P0ENA2. Audio channels are defined as First and Second Long, and First and Third Short, see the Firmware Manual for assignment details. Channel positions and length are common to input and output signals.PCM_CLKo ZL38005 PCMENA1PCMENA2PCMo PCMiB: Master SSI (Mode 3)P_CLKo ZL38005P0FPPCMo PCMiA: Master TDM (Mode 0)PCM_CLKi or ZL38005P0FPPCMo PCMiC: Slave TDM (Modes 1 & 2)PCM_LBCi* ZL38005PCMENA1PCMENA2PCMo PCMiD: Slave SSI (Modes 4, 5 & 6)PCM_CLKi or PCM_LBCi** OSCi/OSCo must be used when the Low Bit Rate Clock (PCM_LBCi) is usedZL38005Data Sheet4.2 SSI OperationFigures 3 illustrates the SSI functional timing used when the two enable strobes (audio channels) are separated by a non-zero number of bit clock cycles. Here the enable signal polarities are active low, either bit clock polarity may be selected. In this format frames are delineated by the active edge of PCMENA1 minus 1/2 bit clock cycle. The frame repetition rate is 8kHz. See Firmware Manual to program the positions of the Audio Channels within the 8kHz frame.Figure 3 - SSI Mode: Separated Channels Functional Timing4.3 I 2S Port DescriptionThe I 2S (Inter-IC Sound) port and PCM Port One share the same physical pins of the ZL38005. Selection of either I 2S port operation or PCM Port One operation is done through the Port One PCM/I 2S Select Register. See Firmware Manual.The I 2S port can be used to connect external Analog-to-Digital Converters or CODECs to the internal DSP . This port can operate in master mode, where the ZL38005 is the source of the port clocks, or slave mode, where the bit and sampling clocks (I 2S_SCK and I 2S_ LRCK) are inputs to the ZL38005. The master clock (I 2S_MCLK) is always an output. In I 2S port master mode the clock signal at output pin I 2S_LRCK is the sampling frequency (f S ), the clock signal at output I 2S_SCK is 32 x f S , and the clock signal at output I 2S_MCLK is 256 x f S . In I 2S port slave mode the relationship between the clock signal at input pin I 2S_LRCK and the clock signal at input I 2S_SCK must be 32 x f S .In slave mode the 256 x f S relationship between f S and the I 2S_MCLK is not mandatory, and the I 2S_MCLK output pin will be in a high impedance state. See Firmware Manual for I 2S programming options.5674Channel 01230PCMENA1PCMENA2PCMi 5674Channel 112305674Channel 01230PCMo5674Channel 11230PCMfpP = PSSISSP = 0PCMfpS[1:0] = 00PCLKP = 1Master/Slave Clock PCLKP = 0Master/Slave Clock Note: PCMi/o are shown as 8-bit audio channels; however, the timing options illustrated here are applicable to 16-bit audio channels as wellMaster Clock - output clocks PCM_CLKoSlave Clock - input clocks PCM_CLKi or PCM_LBCiZL38005Data SheetThe I 2S interface can support two dual channel Analog-to-Digital Converters (Figure 4) or one dual channel CODEC (Figure 5). In Figure 4 pin I 2S_SDi/o is configured as an input (control bit I 2SSDi/oSel = 0) so that the four 16-bit channel processing capacity of the DSP is spread across the two input channels from Dual ADC (0) plus the two input channels from Dual ADC (1). See Firmware Manual for I 2S port setup.Figure 4 - Dual Analog-to-Digital Converter ConfigurationIn Figure 5 pin I 2S_SDi/o is configured as an output (control bit I 2SSDi/oSel = 1) so that the four 16-bit channel processing capacity of the DSP is spread across the two input channels from the ADCs of CODEC(0) and CODEC(1), as well as the two output channels from the ADCs of CODEC(0) and CODEC(1).

It supports both SPI and MICROWIRE modes of operation and can write up to 40 bits or read up to 32 bits in a single access. The Chip Select output signals may be programmed for a single access or burst access. All communication is MSB first and all pins of the master SPI port are outputs controlled by the ZL38005, except SPIM_MISO, se5.2 Host Interface Operation (Slave SPI and UART Ports)The control/status registers and memory of the ZL38005 can be accessed (R/W) by an external host through the Slave SPI and the UART ports.The slave SPI port may be used by an external host microprocessor to access (Read/Write) the ZL38005 internal control/status registers and memory. Access is initiated when the external host makes signal SPIS_CS low and is ended when this signal goes high. The host will then apply a clock (maximum 25MHz) to signal SPIS_CLK to clock data out of SPIS_MISO and in on SPIS_MOSI.The UART (Universal Asynchronous Receiver Transmitter) port may be used by an external host microprocessor to access (Read/Write) the ZL38005 internal control/status registers and memory. The ZL38005 DSP will set up the initial parameters of this port (i.e., master/slave, baud rate, stop bits, parity bit...) during the Boot process. After the device has been booted these port options can be changed as per the Firmware Manual.The UART port will support 8-bit data only with any combination of 1 start bit, 0 or 1 parity bit(s) and 1, 1.5 or 2 stop bit(s).5.3 GPIOThe ZL38005 has 11 GPIO (General Purpose Input/Output) pins that can be individually configured as either input or output. These pins are intended for low frequency signalling.When a GPIO pin is defined as an input the state of that input pin is sampled with the internal master clock (Mclk = 100 MHz) and latched into the GPIO Read Register.Immediately after a power-on reset (RST pin) the GPIO pins are defined as inputs and their state is captured in the GPIO Start-Up Status Register. The state of this register is used by the Boot program to determine the base functionality and programming options of the device.Individual GPIO pins may also be defined as outputs with associated enable/disable (active/high impedance) control. See the Firmware Manual for control and status programming.。

It incorporates two independent DPLLs, each capable of locking to one of eight input references and provides a wide variety of synchronized output clocks and frame pulses.1.1 DPLL FeaturesThe ZL30123 provides two independently controlled Digital Phase-Locked Loops (DPLL1, DPLL2) for clock and/or frame pulse synchronization. Table 1 lists the feature summary for both DPLLs.FeatureDPLL1DPLL2Modes of Operation Free-run, Normal (locked), Holdover Free-run, Normal (locked), Holdover.Loop Bandwidth User selectable: 14Hz, 28Hz, or wideband 1 (890Hz / 56Hz / 14Hz)1. In the wideband mode, the loop bandwidth depends on the frequency of the reference input. For reference frequencies equal to or greater than 64kHz, the loop bandwidth = 890 Hz. For reference frequencies equal to or greater than 8kHz and less than 64 kHz, the loop bandwidth = 56 Hz. For reference frequencies equal to 2kHz, the loop bandwidth is equal to 14Hz.Fixed: 14HzPhase Slope Limiting User selectable: 885ns/s, 7.5µs/s, 61µs/s, or unlimited User selectable: 61µs/s, or unlimited Pull-in Range Fixed: 130ppm Fixed: 130ppm Reference Inputs Ref0 to Ref7Ref0 to Ref7Sync InputsSync0, Sync1, Sync2Sync inputs are not supported.Input Ref Frequencies 2kHz, N * 8kHz up to 77.76 MHz 2kHz, N * 8kHz up to 77.76 MHz Supported Sync Input Frequencies 166.67Hz, 400Hz, 1kHz, 2kHz, 8kHz, 64kHz.Sync inputs are not supported.Input Reference Selection/Switching Automatic (based on programmable priority and revertiveness), or manual Automatic (based on programmable priority and revertiveness), or manual Hitless Ref Switching Can be enabled or disabledCan be enabled or disabled Output Clocksdiff0_p/n, diff1_p/n, sdh_clk0, sdh_clk1, p0_clk0, p0_clk1, p1_clk0, p1_clk1, fb_clk.p0_clk0, p0_clk1, p1_clk0, p1_clk1.Output Frame Pulses sdh_fp0, sdh_fp1, p0_fp0, p0_fp1 synchronized to active sync reference.p0_fp0, p0_fp1 not aligned to sync reference.Supported Output Clock Frequencies As listed in Table 4As listed in Table 4 for p0_clk0, p0_clk1, p1_clk0, p1_clk1Supported Output Frame Pulse Frequencies As listed in Table 4As listed in Table 4 for p0_fp0, p0_fp not aligned to sync reference.External Pins Status IndicatorsLock, HoldoverNoneTable 1 - DPLL1 and DPLL2 FeaturesZL30123Data Sheet1.2 DPLL Mode ControlBoth DPLL1 and DPLL2 independently support three modes of operation - free-run, normal and holdover. The mode of operation can be manually set or controlled by an automatic state machine as shown in Figure 2.Figure 2 - Automatic Mode State MachineFree-runThe free-run mode occurs immediately after a reset cycle or when the DPLL has never been synchronized to areference input. In this mode, the frequency accuracy of the output clocks is equal to the frequency accuracy of the external master oscillator. Lock AcquisitionThe input references are continuously monitored for frequency accuracy and phase regularity. If at least one of the input references is qualified by the reference monitors, then the DPLL will begin lock acquisition on that input. Given a stable reference input, the ZL30123 will enter in the Normal (locked) mode.Normal (locked)The usual mode of operation for the DPLL is the normal mode where the DPLL phase locks to a selected qualified reference input and generates output clocks and frame pulses with a frequency accuracy equal to the frequency accuracy of the reference input. While in the normal mode, the DPLL’s clock and frame pulse outputs comply with the MTIE and TDEV wander generation specifications as described in Telcordia and ITU-T telecommunication standards.HoldoverWhen the DPLL operating in the normal mode loses its reference input, and no other qualified references are available, it will enter the holdover mode and continue to generate output clocks based on historical frequency data collected while the DPLL was synchronized.ResetAnother reference is qualified and availablefor selectionPhase lock on the selected reference is achievedLock AcquisitionNormal (Locked)No references are qualified and available for selectionFree-RunHoldoverSelected referencefailsAll references are monitored for frequency accuracy and phase regularity, and at least one reference is qualified.Normal (Locked)ZL30123Data Sheet1.3 Ref and Sync InputsThere are eight reference clock inputs (ref0 to ref7) available to both DPLL1 and DPLL2. The selected reference input is used to synchronize the output clocks. Each of the DPLLs have independent reference selectors which can be controlled using a built-in state machine or set in a manual mode.Figure 3 - Reference and Sync InputsIn addition to the reference inputs, DPLL1 has three optional frame pulse synchronization inputs (sync0 to sync2)used to align the output frame pulses. The sync n input is selected with its corresponding ref n input, where n = 0, 1,or 2. Note that the sync input cannot be used to synchronize the DPLL, it only determines the alignment of the frame pulse outputs. An example of output frame pulse alignment is shown in Figure 4.Figure 4 - Output Frame Pulse Alignmentref7:0sync2:0DPLL2DPLL1ref nsdh/p0/p1_clk xsdh/p0_fp xWithout a frame pulse signal at the sync input, the output frame pulses will align to any arbitrary cycle of its associated output clock.sync n - no frame pulse signal presentWhen a frame pulse signal is present at the sync input, the DPLL will align the output frame pulses to the output clock edge that is aligned to the input frame pulse.ref n sdh/p0/p1_clk xsdh/p0_fp xsync nn = 0, 1, 2x = 0, 1n = 0, 1, 2x = 0, 1ZL30123Data Sheet Each of the ref inputs accept a single-ended LVCMOS clock with a frequency ranging from 2kHz to 77.76MHz. Built-in frequency detection circuitry automatically determines the frequency of the reference if its frequency is within the set of pre-defined frequencies as shown in Table 2. Custom frequencies definable in multiples of 8kHz are also available.2 kHz8 kHz64 kHz1.544 MHz2.048 MHz6.48 MHz8.192 MHz16.384 MHz19.44 MHz38.88 MHz77.76 MHzCustom ACustom BTable 2 - Set of Pre-Defined Auto-Detect Clock FrequenciesEach of the sync inputs accept a single-ended LVCMOS frame pulse. Since alignment is determined from the rising edge of the frame pulse, there is no duty cycle restriction on this input, but there is a minimum pulse width requirement of 5 ns. Frequency detection for the sync inputs is automatic for the supported frame pulse frequencies shown in Table 3.166.67 Hz(48x 125 µs frames)400 Hz1 kHz2 kHz8 kHz64 kHzTable 3 - Set of Pre-Defined Auto-Detect Sync Frequencies1.4 Ref and Sync MonitoringAll input references (ref0 to ref7) are monitored for frequency accuracy and phase regularity. New references are qualified before they can be selected as a synchronization source, and qualified references are continuously monitored to ensure that they are suitable for synchronization. The process of qualifying a reference depends on four levels of monitoring.Single Cycle Monitor (SCM)The SCM block measures the period of each reference clock cycle to detect phase irregularities or a missing clock edge. In general, if the measured period deviates by more than 50% from the nominal period, then an SCM failure (scm_fail) is declared.ZL30123Data SheetCoarse Frequency Monitor (CFM)The CFM block monitors the reference frequency over a measurement period of 30 µs so that it can quickly detect large changes in frequency. A CFM failure (cfm_fail) is triggered when the frequency has changed by more than 3%or approximately 30000ppm.Precise Frequency Monitor (PFM)The PFM block measures the frequency accuracy of the reference over a 10 second interval. To ensure an accurate frequency measurement, the PFM measurement interval is re-initiated if phase or frequency irregularities are detected by the SCM or CFM. The PFM provides a level of hysteresis between the acceptance range and the rejection range to prevent a failure indication from toggling between valid and invalid for references that are on the edge of the acceptance range.When determining the frequency accuracy of the reference input, the PFM uses the external oscillator’s output frequency (f ocsi ) as its point of reference. Guard Soak Timer (GST)The GST block mimics the operation of an analog integrator by accumulating failure events from the CFM and the SCM blocks and applying a selectable rate of decay when no failures are detected.As shown in Figure 5, a GST failure (gst_fail) is triggered when the accumulated failures have reached the upper threshold during the disqualification observation window. When there are no CFM or SCM failures, the accumulator decrements until it reaches its lower threshold during the qualification window.Figure 5 - Behaviour of the Guard Soak Timer during CFM or SCM FailuresAll sync inputs (sync0 to sync2) are continuously monitored to ensure that there is a correct number of reference clock cycles within the frame pulse period.1.5 Output Clocks and Frame PulsesThe ZL30123 offers a wide variety of outputs including two low-jitter differential LVPECL clocks (diff0_p/n,diff1_p/n ), two SONET/SDH LVCMOS (sdh_clk0, sdh_clk1) output clocks and four programmable LVCMOS (p0_clk0, p0_clk1, p1_clk0, p1_clk1) output clocks. In addition to the clock outputs, two LVCMOS SONET/SDH frame pulse outputs (sdh_fp0, sdh_fp1) and two LVCMOS programmable frame pulses (p0_fp0, p0_fp1) are also available.refCFM or SCM failuresupper thresholdlower thresholdt d - disqualification timet q - qualification time = n * t dt dt qgst_failZL30123Data SheetThe feedback clock (fb_clk ) of DPLL1 is available as an output clock. Its output frequency is always equal to DPLL1’s selected input frequency.The output clocks and frame pulses derived from the SONET/SDH APLL are always synchronous with DPLL1, and the clocks and frame pulses generated from the programmable synthesizers can be synchronized to either DPLL1or DPLL2. This allows the ZL30123 to have two independent timing paths.Figure 6 - Output Clock ConfigurationThe supported frequencies for the output clocks and frame pulses are shown in Table 4.diff0_p/n, diff1_p/n (LVPECL)sdh_clk0, sdh_clk1(LVCMOS)p0_clk0, p1_clk0(LVCMOS)p0_clk1, p1_clk1(LVCMOS)sdh_fp0, shd_fp1, p0_fp0, p0_fp1(LVCMOS)6.48 MHz 6.48 MHz 2 kHz p x _clk0 p x _clk1 =2M166.67 Hz (48x 125 µs frames)19.44 MHz 9.72 MHz N * 8 kHz (up to 77.76 MHz)400 Hz 38.88 MHz 12.96 MHz 1 kHz 51.84 MHz 19.44 MHz 2 kHz 77.76 MHz 25.92 MHz 4 kHz 155.52 MHz 38.88 MHz 8 kHz 311.04 MHz 51.84 MHz 32 kHz 622.08 MHz77.76 MHz64 kHzTable 4 - Output Clock and Frame Pulse FrequenciesDPLL2p0_clk0p0_fp0p0_clk1p0_fp1 P0 SynthesizerDPLL1p1_clk0p1_clk1P1 Synthesizersdh_clk0sdh_fp0sdh_clk1sdh_fp1SONET/SDHAPLLdiff0diff1Feedback Synthesizerfb_clkZL30123Data Sheet1.6 Configurable Input-to-Output and Output-to-Output DelaysThe ZL30123 allows programmable static delay compensation for controlling input-to-output and output-to-output delays of its clocks and frame pulses.All of the output synthesizers (SONET/SDH, P0, P1, Feedback) locked to DPLL1 can be configured to lead or lag the selected input reference clock using the DPLL1 Fine Delay . The delay is programmed in steps of 119.2 ps with a range of -128 to +127 steps giving a total delay adjustment in the range of -15.26 ns to +15.14 ns. Negative values delay the output clock, positive values advance the output clock. Synthesizers that are locked to DPLL2 are unaffected by this delay adjustment.In addition to the fine delay introduced in the DPLL1 path, the SONET/SDH, P0, and P1 synthesizers have the ability to add their own fine delay adjustments using the P0 Fine Delay , P1 Fine Delay , and SDH Fine Delay .These delays are also programmable in steps of 119.2 ps with a range of -128 to +127 steps.In addition to these delays, the single-ended output clocks of the SONET/SDH, P0, and P1 synthesizers can be independently offset by 90, 180 and 270 degrees using the Coarse Delay , and the SONET/SDH differential outputs can be independently delayed by -1.6 ns, 0 ns, +1.6 ns or +3.2 ns using the Diff Delay . The output frame pulses (SONET/SDH, P0) can be independently offset with respect to each other using the FP Delay .Figure 7 - Phase Delay AdjustmentsDPLL1DPLL2P0 Fine Delayp0_clk0p0_clk1p0_fp0p0_fp1 P0 SynthesizerCoarse DelayCoarse Delay FP Delay FP Delay fb_clkp1_clk0p1_clk1 P1 Fine DelayDiff Delay Diff Delaydiff0diff1 SONET/SDHAPLLsdh_clk0sdh_clk1sdh_fp0sdh_fp1 SDH Fine DelayFeedback SynthesizerDPLL1 Fine DelayCoarse Delay Coarse Delay FP Delay FP DelayCoarse Delay Coarse DelayP1 Synthesizer。

Giga-tronics Model 8003精密度标量网络分析器技术数据表说明书

35142Rev.A / US032012The Giga-tronics Model 8003 Precision Scalar Network Analyzer combines a 90 dB widedynamic range with the accuracy and linearity of a power meter in a signal instrument.Scalar Network AnalyzerModel 8003 - 10 MHz to 40 GHzTechnical Datasheet198135142-R e v .A / U S 0320128003 Precision Scalar Network Analyzer1Wide Dynamic RangeThe Model 8003 Precision Scalar Network Analyzer can make accurate, single sensor power measurements over a frequency range of 10 MHz to 40 GHz with a dynamic range of –70 to +20 dBm.This wide dynamic range results from our unique use of switched linear gain stages, with a maximum gain of more than 100 dB, rather than the log amplifiers typically used in other scalar analyzers. In addition to wide dynamic range, our approach also delivers extremely accurate low level measurements all the way down to –70 dBm.Power Meter LinearityThe Model 8003 also incorporates a unique, built-in power sweep calibrator that linearizes the sensor’s diode response inthe non-square-law region, from –30 to +20 dBm. The calibration system uses the inherent linearity and stability of an ovenized thermistor to accurately calibrate the high-speed diode sensors from 0°C to 50°C. The result is a linearity specification of ± 0.02 dB (0.5%) over any 20 dB span and ± 0.04 dB (1%) over the entire 90 dB dynamic range to ensure accurate ratio or relative measurements.Absolute Power MeasurementsThe same built-in calibrator that linearizes the sensor provides a 1 mW signal accurate to within ±0.7%, stable over temperature and time, and traceable to NIST. Each Giga tronics power sensor contains an EEPROM programmed with the frequency calibration factors measured at the factory, or in your Cal Lab. When youkey in the frequency at which power is being measured, the meter automatically applies the correct calibration factor from the sensor EEPROM.The combination of an accurate, traceable calibration reference and an accurate frequency response curve for each powersensor ensures absolute power measurements with power meter accuracy.Power Sensors to meet your Application Giga-tronics offers an extensive line of power sensors for the Model 8003 to address a variety of power measurement applications. This includes standard CW power sensors, low VSWR CW power sensors, true RMS sensors, and our unique triggerable pulse sensors.The 80340 Series triggerable pulse sensors let you display the response from a pulsed source. You can choose between two modes of operation - measure with either a pulsed fixed frequency (CW mode), or with a pulsed swept frequency (start/stop mode) signal from a sweeper (swept signal generator). The sensors can also be used to display the response of devices with no pulse modulation on the signal generator.The Model 8003 incorporates a unique, built-in power sweep calibrator.The 80340 Series triggerable pulse sensors let you display the response from a pulsed source.35142-R e v .A / U S 0320128003 Technical Specifications2System SpecificationsSpecifications describe the instrument’s warranted performance, and apply when using 80300A Series Power Sensors and 80500A Series Bridges.Frequency Range: 10 MHz to 40 GHz in coax using the Giga-tronics 80300 Series power sensors and 80500 Series bridges.Power Range: +30 to -70 dBm, see power sensor specifications.System Dynamic Range:CW Measurements: 90 dB Peak Measurements: 40 dBSwept Measurements: AC Mode 90 dB, DC Mode 80 dB Inputs: Three identical inputs, A, B and C, accept detected outputs from the Giga-tronics power sensors and bridges.DisplayScreen: Full color display.

The smoothing aperture defines the trace width (number of data points) to be averaged. The smoothing aperture can be set from 0.1% to 20% of the trace width.Trace Memory: Ten traces can be individually labeled and stored in non-volatile memory and recalled. Stored traces can bedisplayed, and trace differences from any measurement can be displayed.Adaptive Path Calibration (Normalization): Traces are stored in non-volatile memory and normalized with the highest resolution, independent of display scale/division or offset. Up to 4,096 points for each trace are stored over the full frequency range of the sweeper or any user selected frequency range. Normalization data is automatically interpolated for ranges within the original normalized range.Settings Store/Recall: Allows up to nine front panel setups, plus a power down last instrument state, to be stored and recalled from non-volatile memory.Limit Lines: Horizontal, sloped, and/or single point lines for each trace can be set as go/no-go data limits. Limit lines are stored in non-volatile memory. Complex limit lines can be entered through the front panel or via GPIB interface.35142-R e v .A / U S 0320128003 Precision Scalar Network Analyzer3Cursors and MarkersCursor: The cursor can be positioned with the tuning knob or via the numeric keypad. The frequency and amplitude test data at the cursor on all active channels is digitally displayed.Cursor Delta: Displays differences in dB and frequency between the reference cursor and the main cursor.Cursor Min/Max: Automatically moves the cursor to the minimum or maximum value of test data.Cursor “x” dB: Automatically moves the cursor to the point on the trace equal to the value of “x” in dB or dBm.Cursor “x” Bandwidth: Automatically displays cursors right and left of the cursor at the frequencies where the test data is equal to the value of “x” dB, and displays the bandwidth between the cursors.Ref to Cursor: Automatically changes the Ref Level to the level at the cursor.Markers: Displays up to 10 markers generated by the 8003. The cursor can be moved directly to any marker or moved sequentially through the markers.AccuracyTransmission Loss or Gain Measurement: Transmission loss or gain measurements are made relative to a 0 dB reference pointestablished during calibration. Therefore, frequency response errors of the source, sensors, and signal splitting device are removed. The remaining elements of uncertainty are mismatch error, instrument linearity (Fig. 1) and noise uncertainty given in the absolute power accuracy section.Transmission Accuracy = Instrument Accuracy + Mismatch Uncertainty35142-Re v .A/ U S 0320128003 Technical Specifications4Reflection Measurements: When measuring devices with high return loss (>10 dB), reflection accuracy is typically dominated by the effective system directivity (Fig. 2), instrument linearity errors, and noise uncertainty. With low return loss devices (<10 dB), reflection accuracy is typically dominated by source match (Fig. 3). Calibration with an open and short effectively removes uncertainties due to frequency response of the source, sensors, and signal splitting device.Reflection Accuracy = Instrument Accuracy + Reflection Bridge Accuracy35142-R e v .A / U S 0320128003 Precision Scalar Network Analyzer5Absolute Power Measurement Accuracy: The absolute power measurement accuracy is determined by a number of factors including calibrator accuracy, noise, sensor calibration factor error, and the mismatch uncertainty between sensor and device under test.Calibrator: Provides a 50 MHz calibration signal at 51 veryaccurately controlled levels from +20 to -30 dBm to dynamically linearize the sensors.Calibrator Frequency: 50 MHz nominalCalibrator Connector: Type-N (f) precision connector, 50 Ω.Settability: The 1.00 mW level in the power sweep is factory set to ±0.7% traceable to the National Institute of Standards and Technology (NIST).Accuracy: ±1.2% worst case for one year, over temperature range 15°C to 35°C.Calibrator VSWR: < 1.05:1 (Return Loss > 33 dB)Instrument plus Power Sensor Linearity:Standard Sensors, CW Mode:±0.02 dB (±0.5%) over any 20 dB range from +16 to -70 dBm ±0.02 dB + (+0 dB, -0.05 dB/dB) from +16 to +20 dBm ±0.04 dB (±1.0%) from +16 to -70 dBm Standard Sensors, Swept Mode:±0.03 dB (±0.7%) over any 20 dB range from +16 to -70 dBm ±0.03 dB + (+0 dB, -0.05 dB/dB) from +16 to +20 dBm ±0.06 dB (±1.4%) from +16 to -70 dBmLow VSWR Sensors:-64 to +20 dBm: Same as for Standard Sensors.+20 to +30 dBm: Same as for Standard Sensors, plus an additional ±0.13 dB (typical).High Power Sensors:-60 to +20 dBm: Same as for Standard Sensors.+20 to +30 dBm: Same as for Standard Sensors, plus an additional ±0.13 dB (typical).True RMS Sensors, CW Mode:±0.02 dB (±0.5%) over any 20 dB range from +20 to -30 dBm ±0.04 dB (±1.0%) from +20 to -30 dBm True RMS Sensors, Swept Mode:±0.03 dB (±0.7%) over any 20 dB range from +20 to -30 dBm ±0.06 dB (±1.4%) from +20 to -30 dBmTemperature Coefficient of Linearity: < 0.3%/°C temperature change after calibrationZeroing Accuracy, (CW Mode, Averaging Factor = 32): Zero set: ±50 pWZero drift: < ±200 pW (typical) in 1 hour at constant temperature after at 24 hour warm-up.Zeroing Accuracy, (Swept Mode, Averaging Factor = 32):Zero set: ±50 pW (AC Detection), ±800 pW (DC Detection)Zero drift: 2 nW (DC detection), typical, in 1 hour at constant temperature after 24 hour warm-up.

2.0 Acoustic Echo Canceller (AEC) Description
The AEC section is comprised of an acoustic echo canceller, noise reduction and the operational control functions for operation. The AEC guarantees clear signal transmission in both transmit and receive audio path directions ensuring reliable voice communication even when low level signals are provided. The AEC does not use variable attenuators during double-talk or single-talk periods of speech, as do many other acoustic echo cancellers for speakerphones. Instead, the AEC provides high performance full-duplex operation similar to network echo cancellers. This results in users experiencing clear speech and uninterrupted background signals during the conversation and prevents subjective sound quality problems associated with “noise gating” or “noise contrasting”.
