Leakage test accuracy is limited by tester resource accuracy and tester hardware.2. For gain 100 PGA input common mode is 0V and the minimum supply is3.15V.3. The measurement ranges are referred only by the gain of input amplifier, while other parameters such as bandwidth etc. are pro-grammed independently.4. This parameter is not measured directly in production. It is measured indirectly via gain measurements of the whole path. It is guaran-teed by design.5. Pole frequency of input amplifier changes with GAIN. The number is valid for the gain at G1, while the bandwidth will be higher for other ranges. This parameter is not measured in production.6. Based on device evaluation. Not tested.7. These offsets are cancelled if chopping enabled (default).8. Noise density calculated by taking system bandwidth as 150Hz.9. Refer to Measurement Ranges shown in Table 13.10. No impact on the measurement path. If the chopping is enabled, both the offset and offset drift will be eliminated.11. For negative input voltages up to -160mV below ground, Input leakage is typically -20nA @ 65ºC due to forward conductance of protection diode.Table 15.

Servicing:Refer servicing to qualified technical personnel only.INTRODUCTIONThank you for purchasing the ART T8 Universal Eight Channel Transformer Isolator. This is a rock solid, road-worthly 8 channel transformer isolator. “Hum” in an audio system is often caused by loop effects which act like antennas. These loops can easily pick up a 60Hz ( or higher harmonic) hum created by electrical wiring. Typically, these loops are connected via grounds, more commonly called “ ground loops”. The safest way to eliminate unwanted noise is with the T8.The T8 is a quality totally passive audio interface that uses eight high performance low distortion transformers to totally separate input and output signal grounds, thereby isolating two systems and reducing hum and ground-loop noise. The T8’s audio transformers have an extremely flat and wide frequency response and can handle high signal levels while maintaining an isolated balanced output. This gives the T8 a very clean and neutral sound with a wide variety of signal sources. The transformers are wound for 1:1 unity gain and are designed for use with impedances from 600 Ohms to 100k Ohms.What further sets the T8 apart from other lesser isolation boxes is its connection versatility. We have provided XLR, ¼” phone, and RCA type phono connections on all inputs and outputs. This allows it to easily fit into virtually any audio system and be the clean patch point between all types of systems. All ¼” and RCA phono jacks are on the front and all XLR jacks are on the rear. You can use any combination and since the jacks are directly paralleled you can also use them as signal taps or as a signal splitter.The T8’s mounting ears are reversible so you can have either the ¼” and RCA phono jacks on the front or the XLRs on the front. This maximizes flexibility in cabling your system. Whether you need an interface between a computer based audio workstation and your monitor system, isolation on long cable runs in a fixed installation, isolation of multiple signal sources from your recording equipment, or in many cases, just a safer connection between two audio systems, the T8 can accommodate. The 19” 1U black all steel case and its all passive design allow the T8 to provide years of trouble free service in Live Sound, Permanent/Fixed Install, D.J., and virtually any PA application. It is equally valuable in a variety of studio and AV applications. Its full feature set, rugged construction, and high-end specifications make the T8 the obvious choice.APPLICATIONS:LIVE SOUND, D.J.Long unbalanced cables are more susceptible to picking up hum , Using the T8 to help balance these and eliminate any hum.When DJs set up for different jobs there is a potential to pick up hum due to the differences in house wiring, using a T8 Eliminates the potential for hum.MIXERS/FIXED INSTALLS/RECORDING/BROADCAST/VIDEOUse the T8 to eliminate ground loops when using multiple mixers.Taking mixer unbalanced sends and achieving true balanced monitor outputs.Using the T8 between video/broadcast rigs eliminates the potential for hum and loop noise.POWER AMPLIFIERSHum, ground loop noise can be created between multiple amplifiers. This can be eliminated using the T8 on each of the amplifiers input lines.COMPUTERSUsing a T8 can eliminate unwanted ground loops created between the computers and your audio input equipment.You can also use the T8 to balance the unbalanced inputs and outputs from your computers sound card.WARRANTY INFORMATIONLimited WarrantyApplied Research and Technology will provide warranty and service for this unit in accordance with the following warrants:Applied Research and Technology, (A R T) warrants to the original purchaser that this product and the components thereof will be free from defects in workmanship and materials for a period of three years from the date of purchase.

Existing requirements demand time slot interchange devices performing switching with constant throughput delay while guaranteeing minimum delay for voice channels.The MT8985 device provides both functions and allows existing systems based on the MT8980D to be easily upgraded to maintain the data integrity while multiple channel data are transported. The device is designed to switch 64 kbit/s PCM or N x 64kbit/s data. The MT8985 can provide both frame integrity for data applications and minimum throughput switching delay for voice applications on a per channel basis.By using Mitel Message mode capability, the microprocessor can access input and output time slots on a per channel basis to control devices such as the MITEL MT8972, ISDN Transceivers and T1/CEPT trunk interfaces through the ST -BUS interface.Different digital backplanes can be accepted by the MT8985 device without user's intervention. The MT8985 device provides an internal circuit thatautomatically identifies the polarity and format of frame synchronization input signals compatible to ST -BUS and GCI interfaces.Device OperationA functional block diagram of the MT8985 device is shown in Figure 1. The serial ST -BUS streams operate continuously at 2.048 Mb/s and are arranged in 125µs wide frames each containing 32 8-bit channels. Eight input (STi0-7) and eight output (STo0-7) serial streams are provided in the MT8985device allowing a complete 256 x 256 channel non-blocking switch matrix to be constructed. The serial interface clock for the device is 4.096 MHz, as required in ST -BUS and GCI specifications.Data MemoryThe received serial data is converted to parallel format by the on-chip serial to parallel converters and stored sequentially in a 256-position Data Memory. The sequential addressing of the Data Memory is generated by an internal counter that is reset by the input 8 kHz frame pulse (F0i) marking the frame boundaries of the incoming serial data streams.Depending on the type of information to be switched,the MT8985 device can be programmed to perform元器件交易网MT89852-48time slot interchange functions with different throughput delay capabilities on a per-channel basis.For voice applications, the variable delay mode can be selected ensuring minimum throughput delay between input and output data. In multiple or grouped channel data applications, the constant delay mode can be selected maintaining the integrity of the information through the switch.Data to be output on the serial streams may come from two sources: Data Memory or Connect Memory.Locations in the Connect Memory, which is split into HIGH and LOW parts, are associated with particular ST -BUS output streams. When a channel is due to be transmitted on an ST -BUS output, the data for the channel can either be switched from an ST -BUS input (connection mode) or it can be originated from the microprocessor (message mode). If a channel is configured in connection mode, the source of the output data is the Data Memory. If a channel is configured in message mode, the source of the output data is the Connect Memory Low. Data destined for a particular channel on the serial output stream is read from the Data or Connect Memory Low during the previous channel time slot. This allows enough time for memory access and internal parallel to serial conversion.Connection and Message ModesIn connection mode, the addresses of input source for all output channels are stored in the Connect memory Low. The Connect Memory Low locations are mapped to each location corresponding to an output 64 kb/s channel. The contents of the Data memory at the selected address are then transferred to the parallel to serial converters. By having the output channel to specify the input channel through the connect memory, the user can route the same input channel to several output channels, allowing broadcasting facility in the switch.In message mode the CPU writes data to the Connect Memory Low locations which correspond to the output link and channel number. The contents of the Connect Memory Low are transferred to the parallel to serial converter one channel before it is to be output. The Connect Memory Low data is transmitted each frame to the output until it is changed by the CPU.The per-channel functions available in the MT8985are controlled by the Connect Memory High bits,which determine whether individual output channels are selected into specific conditions such as:message or connection mode, variable or constant throughput delay modes, output drivers enabled or inthree-state condition. In addition, the Connect Memory High provides one bit to allow the user to control the state of the CSTo output pin.If an output channel is set to three-state condition,the TDM serial stream output will be placed in high impedance during that channel time. In addition to the per-channel three-state control, all channels on the TDM outputs can be placed in high impedance at one time by pulling the ODE input pin in LOW. This overrides the individual per-channel programming on the Connect Memory High bits.The Connect Memory data is received via the Microprocessor Interface at D0-D7 lines. The addressing of the MT8985 internal registers, Data and Connect memories is performed through address input pins and some bits of the device's Control register. The higher order address bits come from the Control register, which may be written or read through the microprocessor interface. The lower order address bits come directly from the external address line inputs. For details on the device addressing, see Software Control and Control register description.Serial Interface TimingThe MT8985 master clock (C4i) is a 4.096 MHz allowing serial data link configuration at 2.048 Mb/s to be implemented. The MT8985 frame synchronization pulse can be formatted according to ST -BUS or GCI interface specifications; i.e., the frame pulse can be active in HIGH (GCI) or LOW (ST -BUS). The MT8985 device automatically detects the presence of an input frame pulse and identifies the type of backplane present on the serial interface.Upon determining the correct interface connected to the serial port, the internal timing unit establishes the appropriate serial data bit transmit and sampling edges. In ST -BUS mode, every second falling edge of the 4.096 MHz clock marks a bit boundary and the input data is clocked in by the rising edge, three quarters of the way into the bit cell. In GCI mode,every second rising edge of the 4.096 MHz clock marks the bit boundary while data sampling is performed during the falling edge, at three quarters of the bit boundaries.Delay through the MT8985The transfer of information from the input serial streams to the output serial streams results in a delay through the MT8985 device. The delay through the MT8985 device varies according to the mode selected in the V/C bit of the connect memory high.元器件交易网MT89852-49Variable Delay modeThe delay in this mode is dependent only on the combination of source and destination channels and it is not dependent on the input and output streams.The minimum delay achievable in the MT8985 device is 3 time slots. In the MT8985 device, the information that is to be output in the same channel position as the information is input (position n), relative to frame pulse, will be output in the following frame (channel n, frame n+1). The same occurs if the input channel has to be output in the two channels succeeding (n+1 and n+2) the channel position as the information is input.The information switched to the third timeslot after the input has entered the device (for instance, input channel 0 to output channel 3 or input channel 30 to output channel 1), is always output three channels later.Any switching configuration that provides three or more timeslots between input and output channels,will have a throughput delay equal to the difference between the output and input channels; i.e., the throughput delay will be less than one frame. Table 1shows the possible delays for the MT8985 device in Variable Delay mode:Table 1Constant Delay ModeIn this mode frame integrity is maintained in all switching configurations by making use of a multiple Data-Memory buffer technique where input channels written in any of the buffers during frame N will be read out during frame N+2. In the MT8985, the minimum throughput delay achiev-able in Constant Delay mode will be 32 time slots; for example, when input time slot 32 (channel 31) is switched to output time slot 1 (channel 0). Likewise, the maximum delay is achieved when the first time slot in a frame (channel 0) is switched to the last time slot in the frame (channel 31), resulting in 94 time slots of delay.To summarize, any input time slot from input frame N will be always switched to the destination time slot onInput ChannelOutput Channel Throughput Delay n m=n, n+1 orn+2m-n + 32 timeslots n m>n+2m-n time slotsnm<n 32-(n-m) time slotsoutput frame N+2. In Constant Delay mode, the device throughput delay is calculated according to the following formula:DELAY = [32 + (32 - IN) + (OUT - 1)];(expressed in number of time slots)Where:IN is the number of the input time slot (from 1 to 32).OUT is the number of the output time slot (from 1 to 32).Microprocessor PortThe MT8985 microprocessor port has pin compatibility with Mitel MT8980 Digital Switch device providing a non-multiplexed bus architecture. The parallel port consists of an 8 bit parallel data bus (D0-D7), six address input lines (A0-A5) and four control lines (CS, DS, R/W and DT A). This parallel microport allows the access to the Control registers,Connection Memory High, Connection Memory Low and the Data Memory. All locations are read/written except for the data memory which can be read only.Accesses from the microport to the connection memory and the data memory are multiplexed with accesses from the input and output TDM ports. This can cause variable Data Acknowledge delays (DT A).In the MT8985 device, the DTA output provides a maximum acknowledgement delay of 800 ns for read/write operations in the Connection Memory.However, for operations in the Data Memory (Message Mode), the maximum acknowledgement delay can be 1220 ns.Figure 3 - Address Memory MapNote: "x" Don’t careSoftware ControlThe address lines on the microprocessor interface give access to the MT8985 internal registers and memories.

If A5 input line is HIGH,then the remaining address input lines are used to select Memory subsections of 32 locations corresponding to the number of channels per input or output stream. As explained in the Control register description, the address input lines and the Stream Address bits (STA) of the Control register give the user the capability of selecting all positions of the MT8985 Data and Connect memories.The data in the Control register consists of Split memory and Message mode bits, Memory select and Stream Address bits (see Figure 4). The memory select bits allow the Connect Memory HIGH or LOW or the Data Memory to be chosen, and the Stream Address bits define an internal memory subsections corresponding to input or output ST -BUS streams.Bit 7 (Split Memory) of the Control register allows split memory operation whereby reads are from the Data memory and writes are to the Connect Memory LOW.The Message Enable bit (bit 6) places every output channel on every output stream in message mode;i.e., the contents of the Connect Memory LOW(CML) are output on the ST -BUS output streams once every frame unless the ODE input pin is LOW.If ME bit is HIGH, then the MT8985 behaves as if bits 2 (Message Channel) and 0 (Output Enable) of every Connect Memory HIGH (CMH) locations were set to HIGH, regardless of the actual value. If ME bit is LOW, then bit 2 and 0 of each Connect Memory HIGH location operates normally. In this case, if bit 2of the CMH is HIGH, the associated ST -BUS output channel is in Message mode. If bit 2 of the CMH is LOW, then the contents of the CML define the source information (stream and channel) of the time slot that is to be switched to an output.If the ODE input pin is LOW, then all serial outputs are high-impedance. If ODE is HIGH, then bit 0(Output Enable) of the CMH location enables (if HIGH) or disables (if LOW) the output drivers for the corresponding individual ST -BUS output stream and channel.The contents of bit 1 (CSTo) of each Connection Memory High location (see Figure 5) is output on CSTo pin once every frame. The CSTo pin is a 2048Mbit/s output which carries 256 bits.

Bit 4 is the most significant bit.*If bit 2 of the corresponding Connection High location is 1 or if bit 6 of the Control Register is 1, then these entire 8 bits are output on the channel and stream associated with this location. Otherwise, the bits are used as indicated to define the source of the connection which is output on the channel and stream associated with this location.XV/CXXXMCCSToOE76543210SAB2SAB1SAB0CAB4CAB3CAB2CAB1CAB076543210transmitted in HIGH. If CSTo bit is LOW, the corresponding bit on the CSTo output is transmitted in LOW. The contents of the 256 CSTo bits of the CMH are transmitted sequentially on to the CSTo output pin and are synchronous to the ST -BUS streams. To allow for delay in any external control circuitry the contents of the CSTo bit is output one channel before the corresponding channel on the ST -BUS streams. For example, the contents of CSTo bit in position 0 (ST0, CH0) of the CMH, is transmitted synchronously with ST -BUS channel 31, bit 7. The contents of CSTo bit in position 32 (ST1, CH0) of the CMH is transmitted during ST -BUS channel 31 bit 6.Bit V/C (Variable/Constant Delay) on the Connect Memory High locations allow per-channel selectionbetween Variable and Constant throughput delay capabilities.Initialization of the MT8985On initialization or power up, the contents of the Connection Memory High can be in any state. This is a potentially hazardous condition when multiple MT8985 ST -BUS outputs are tied together to form matrices, as these outputs may conflict. The ODE pin should be held low on power up to keep all outputs in the high impedance condition.元器件交易网MT89852-52Figure 7 - Typical Exchange, PBX or Multiplexer ConfigurationS/UBasic Rate Line CardMT8930/31MT8910MT8972ST-BUSTo other linesLayers2 & 3EntityMT8940/MT8941ROUTINGMATRIXMT8985’sMH89760/MH89790MT8920µCST-BUSST-BUST1/E1LinkTo other linesPrimary Rate CardCPUDuring the microprocessor initialization routine, the microprocessor should program the desired active paths through the matrices, and put all other channels into the high impedance state. Care should be taken that no two connected ST-BUS outputs drive the bus simultaneously. When this process is complete, the microprocessor controlling the matrices can bring the ODE signal high to relinquish high impedance state control to the CMH b0s. ApplicationsTypical Exchange, PBX or MultiplexerFigure 7 shows a typical implementation of line cards being interconnected through a central routing matrix that can scale up in channel capacity to accommodate different number of ports depending on the application. In a configuration where the switched services utilize concatenated or grouped time slots to carry voice, data and video (channels of 128, 256 Kb/s, ISDN H0 and others), the central routing matrix has to guarantee constant throughput delay to maintain the sequence integrity between input and output channels. Figure 7 shows an example where the MT8985 device guarantees data integrity when data flows from the T1/E1 to the S/U interface links and vice-versa. Modern technologies available today such as Frame Relay network using dedicated fractional T1 are one of the key applications for the MT8985 device.Low Latency Isochronous NetworkIn today's local working group environment, there is an increasing demand for solutions on interconnection of desktop and telephone systems so that mixed voice, data and video services can be grouped together in a reliable network allowing the deployment of multimedia services. Existing multimedia applications require a network with元器件交易网MT89852-53Figure 8a - Private Isochronous NetworkAccess to Public NetworkAnalog Connections• • • • • •ISDN Desktopsn x 64Connections (e.g. Video)Isochronous NetworkServer 1Server 2Server 3Server 4T1T1E1• • • • • •• • • • • •T1/E1(2B+D)predictable data transfer delays that can be implemented at a reasonable cost. The Low Latency Isochronous Network is one of the alternatives that system designers have chosen to accommodate this requirement (see Figure 8a). This network can be implemented using existing TDM transmission media devices such as ISDN Basic (S or U) and Primary rates trunks (T1 and CEPT) to transport mixed voice and data signals in grouped time slots; for example,2B channels in case of ISDN S or U interfaces or up to 32 channels in case of a CEPT link.Figure 8b shows a more detailed configuration whereby several PCs are connected to form an Isochronous network. Several services can be interconnected within a single PC chassis through the standardized Multi Vendor Integration Protocol (MVIP). Such an interface allows the distribution and interconnection of services like voice mail, integrated voice response, voice recognition, LAN gateways,key systems, fax servers, video cards, etc.The information being exchanged between cards through the MVIP interface on every computer as well as between computers through T1 or CEPT links is, in general, of mixed type where 64Kb/s and N*64Kb/s channels are grouped together. When such a mixed type of data is transferred between cards within one chassis or from one computer to another, the sequence integrity of the concatenated channels has to be maintained. The MT8985 device suits this application and can be used to form a complete non-blocking switch matrix of 512 channels (see Figure 9). This allows 8 pairs of ST -BUS streams to be dedicated to the MVIP side whereas the remaining 8 pairs are used for local ancilliary functions in typical dual T1/E1 interface applications (Figure 10).Another application of the MT8985 in an MVIP environment is to build an ISDN S-interface card (Figure 11). In this card, 7 pairs of ST -BUS streams are connected to the MVIP interface while the remaining pair is reserved for the interconnection of MITEL MT8930 (SNIC), MT8992 (H-PHONE) and the MVIP interface.元器件交易网MT89852-54Figure 8b - Implementation of an Isochronous Network Using Mitel ComponentsServer 1MH89760BMH89790BST-BUSMT8985s(x4)MT8930BMT8930B••••••••••••MVIPBUSISDNS-InterfaceLocal T1/E1 LinkMVIPBUSServer 3(256 PORTSWITCH MODULE)Server 3MH89760B/790BMH89760B/790BMH89760B/790BST-BUS MT8985s(x4)HDLCMT8985MT8985MT8985MT8985ST-BUS MH89760BMH89790BDual T1/E1 CardMH89760BMH89790BMT8972BorANALOGMT8985s(x4)Server 2MVIPBUSST-BUSTo Video, Data,Fax ServicesLocal Environment Network Access••••••Local T1/E1 LinkT1E1 To Video, Data, Fax and other servicesPublic元器件交易网。

In addition to the classic A-to-D and D-to-A con-version, each channel provides termination imped-ance synthesis and a hybrid balance network.The device is controlled by a serial microprocessor interface, and a series of bidirectional I/O leads are provided so that this control mechanism can be uti-lized to operate the battery feed device, ringing volt-age switches, etc. Common data and clock paths can be shared over any number of devices.

Functionality includes line termination impedance synthesis, fixed hybrid balance impedance synthesis, and level conversion both in the analog sense toaccommodate various subscriber line interface circuits (SLICs) and in the digital sense for adjustment of the levels on the PCM bus. In general, the termination impedance synthesis generates the equivalent of a cir-cuit with the parallel combination of a capacitor and a resistor in series with a resistor or the parallel combina-tion of a resistor and the series combination of a resis-tor and capacitor. These general forms of impedance characteristic will satisfy most of the requirements specified throughout the world. Programmable selec-tion of either µ-law or A-law encoding further aidsworldwide deployment. All coefficients used in the filter-ing algorithms can be computed off-line in advance anddownloaded to the device at the time of powerup. All signal processing is contained within the device, and there are only three interfaces of consequence to the system designer: the SLIC interface, the PCM inter-face, and the control interface.The SLIC interface is designed to be flexible and con-venient to use with a variety of SLIC circuits. With an appropriate choice of SLIC, few external components are required in the interface.Preliminary Data SheetAugust 2001 T8538B Quad Programmable CodecGeneral Description (continued)The PCM bus interface is flexible in that it allows, inde-pendently, the transmit and receive data for any chan-nel to be placed in any time slot. The bus can be operated at a maximum 16.384 Mbits/s rate to accom-modate a maximum 256 time slots. Separate pinsare provided for each direction of transmission to allow 4-wire bus operation. The frame strobe signal is an 8 kHz signal that defines the beginning of the frame structure for all four channels. The interface will count 8 bits per time slot and insert or read the data for each channel as programmed. Lower speeds of the PCM bus are allowed. The PCM clock must be synchronous with the frame strobe signal.The microprocessor control interface is a serial inter-face that uses the classical chip select type of opera-tion. The interface controls the device by writing or reading various internal addresses. The command set consists of simple read and write operations, with the address determining the effect. All the memory loca-tions, including the per-chip functions, are organized by channel.There are several test modes included to facilitate con-firmation of correct operation. In the signal path, two analog and three digital loopback tests are available, while in the microprocessor interface, there is a write/ read test mode that tests the operation of the memory. Use of external test access switches allows a complete test of the signal path through the line card so that cor-rect operation of various operational modes can be ver-ified.4Agere Systems Inc.Agere Systems Inc.5Preliminary Data Sheet August 2001T8538B Quad Programmable CodecPin Information5-8885a (F)Figure 2. 100-Pin TQFP Pin DiagramTable 1.

This lead has an internal pull-up.8Agere Systems Inc.Preliminary Data SheetAugust 2001T8538B Quad Programmable CodecFunctional DescriptionClocking ConsiderationsThe PCM bus uses a bit clock (BCLK) and a frame syn-chronization pulse (FS) to determine the location of the beginning of a frame. These two clocks must be derived from the same source. Internally, the device develops all the internal clocks with a phase-locked loop that uses BCLK as the timing source. BCLK and FS must be continuously present and without gaps in order for the device to operate correctly.DCLK is used to clock the internal serial interface and may be asynchronous to the other clocks. There is no need to derive this clock from the same source as the other clocks. The serial bus may be operated at any speed up to 4.096 Mbits/s. DCLK can be gapped. There is no limit on the number of devices on the same serial bus.The Control InterfaceThe device is controlled via a series of memory loca-tions accessed by a serial data connection to the exter-nal master controller. This interface operates using the chip select lead to enable transmission of information. All chip functions are enabled or disabled by setting or clearing bits in the control memory. Filter coefficients and gain adjustments are also stored in this memory. The codec has both a serial input lead and a serial out-put lead. These may be used individually for a 4-wire serial interface, or tied together for a 2-wire interface. The line driver circuitry is capable of driving relatively high currents so that in the event that the line is long enough to show significant transmission line effects, it can be terminated in the characteristic impedance at each end with resistors to V CC and ground.All data transfers on the serial bus are byte oriented with the least significant bit (shown in this data sheet as bit 0) transmitted first, followed by the more significant bits. For data fields, the least significant byte of the first data byte is transmitted first, followed by the more sig-nificant bytes, each byte transmitted LSB first. This for-mat is compatible with the serial port on most microcontrollers.ModesThere are two different modes of operation for the serial interface: the normal mode and the byte-by-byte mode. These two modes differ in the data clocking and the manner in which CS is used to control the transfer. Note that the CS lead is used to control the transfer of serial data from master controller to slave codec and in the reverse direction.In normal mode (INTS pin open), the CS lead must go low for the duration of the transfer. CS is latched by DCLK on a positive-going clock edge. DI is latched by DCLK on a negative-going clock edge. DCLK may be continuous, but only needs to be present to clock data when CS is low (gapped clock). When using gapped clock, DCLK can remain high or low when CS is high. The only error check performed by the codec is to ver-ify that CS is low for an integral number of bytes. Detection of an active chip select for other than an inte-gral multiple of 8bits results in the operation being ter-minated. The next active excursion of chip select will be interpreted as a new command; hence, the serialI/O interface can always be initialized by asserting CS for a number of clock periods that is not an integral multiple of 8. CS is captured using DCLK, so DCLK must be transitioned to perform this initialization.The byte-by-byte mode (INTS pin tied to ground) uses CS to control each byte of the transfer. In this mode, CS goes low for exactly 8 bits at a time, corresponding to a 1-byte transfer either to or from the codec chip. DCLK can be continuous or gapped. When using a gapped clock, DCLK can remain high or low when CS is high. CS and DI are latched by DCLK on a positive- going clock edge. Repeated transitions of CS are used to control subsequent bytes of data to/from the codec. For a write command in this mode, CS must go low for each byte of the transfer until the transfer is complete. For a read command, CS will go low for each of the3 bytes of the read command transferred to the device, then low again for each byte to be read. Notice that the total number of bytes transferred (and excursions on CS) is N + 3, where N is the number of bytes to be read in the command. This mode of operation is useful in cases where the master is a microprocessor with a built-in UART that transfers 1 byte at a time. Error detection is limited to detection of an active CS for other than an integral multiple of 8 bits. Recovery is the same as normal mode.Flow control can be accomplished by suspending the transitions on DCLK by holding either state. During the data transfer, CS must remain low while clock transi-tions are suspended with DCLK in either state.Agere Systems Inc.9Preliminary Data SheetAugust 2001 T8538B Quad Programmable CodecFunctional Description (continued)The Control Interface (continued)ProtocolThe format of the command protocol is shown in Fig-ures 4 and 5.The control interface operates with one external master controller and multiple slave codec devices. Each transfer is initiated by the master, and the slave responds for either read operations or the fast scan mode. The slave does not check the bus for activity prior to transmitting; it only checks for an active CS. The master should allow for a wait between the end of a read command until CS becomes active for the read data. The master must refrain from sending additional commands to the slave chip until the response is received. On a 4-wire bus, commands to other devices may be initiated before the response is received, but care in generating the CS function is needed to ensure that the multiple responses do not interfere. It should be noted that multiple memory locations can be accessed in the same command by setting the data field length field to the desired number of bytes to be transferred. If flow control is desired, it must be per-formed by using separate commands, each transfer-ring smaller blocks of information, or by controlling the serial clock (gapping the serial clock), or with CS in the case of byte-by-byte mode.There is no response from the slave to the master for a write operation. The response to a read operation sim-ply includes the data to be read in the data field. Com-mands from the master controller include data for write operations, but not for read operations.All data is transmitted in a byte-oriented fashion with the least significant bit of each byte transferred first. Multibyte fields are transferred least significant byte first in both directions. The data field will contain the first addressed data location first, with subsequent data locations transmitted in ascending order.Since the coefficients and gains are stored in volatile memory, all the coefficients and gains must be loaded after powerup. There is, however, no need to reload them when switching from active to standby modes, or vice versa.10Agere Systems Inc.Functional Description (continued)The Control Interface (continued)Protocol (continued)*Location of memory bank selection. All user controls are in memory bank 0; other memory banks contain internal state information for the device. Note:Data field length is in bytes for all operations. All data is transmitted in bytes with the LSB for each byte transmitted first. For 16-bit mem-ory operations, the least significant byte of the first memory location is transmitted first, followed by the most significant b yte; each byte is transmitted LSB first. Additional memory locations are loaded in ascending sequence.Figure 4. Command Frame Format, Master to Slave, Read or Write CommandsNote:All data is transmitted in bytes with the LSB for each byte transmitted first.

These two reset functions have different effects, and each of the software reset functions is a subset of the hardware reset functional-ity. The primary difference is in the treatment of the internal memory. The hardware reset is assumed to be a result of a catastrophic hardware event, such as a loss of power or an initial powerup. Accordingly, the assumption is made that the internal memory does not contain valid data and default values for all memory locations are loaded. A software reset, however, can only be initiated if the device is operational (at least the microprocessor interface), so the contents of the mem-ory may indeed be valid; thus, the resets may be more specific. Additionally, software resets only affect the selected channel.A 0.1 µF capacitor between the RST lead and ground will effectively hold the lead low long enough to reset the device on powerup, allowing for a cost-effective power-on reset function. Notice that the memory must be reloaded through the serial interface after a hard-ware reset function. For proper operation, it is neces-sary for FS and BCLK to be present and stable during a reset. A wait period for the internal PLL to stabilize is required after reset goes high. See the timing diagram shown in Figure 18 for the proper hardware or power-on reset procedure.For a software reset, the control memory should not be accessed for a minimum of 256 µs following the reset. Memory Control MappingSeveral memory locations are used to control the device. The software interface tables (Table 16 and Table 17) show the memory assignments that are use-ful in call processing and system testing. It should be noted that other memory locations are used by the device to hold intermediate results and other device state information. Writing to these other locations can cause serious disruptions in the operation of the device and should be avoided. Standby ModeThe device enters a low-power standby mode with powerup or software reset, or by programming the CHACTIVE register 129, bit 0. In standby mode, the control interface is active, capable of writing or reading registers. SLIC read and write data latches are also active. Analog signals at VF X I and PCM signals at D R are ignored in this mode. BCLK must be present for proper standby mode operation.Test CapabilitiesThe device has several built-in test capabilities that can be used to verify correct operation of the signal pro-cessing of the line card. These test functions are accessed in several different control addresses. Five loopback modes are employed: the first for the digital signal from the PCM bus to be looped back to the PCM bus. This loopback facility can be used to verify correct operation of the PCM bus interface logic, as well as operation of the PCM bus. The second digital loopback function allows complete testing of the digital process-ing capability of the codec by looping the data back at the analog/digital conversion interface. The third loop-back function can be used to check the operation of all the signal processing performed in the device, includ-ing the conversions to/from analog. These digital loop-back functions can be used with tone generation and reception via the PCM bus.The first analog loopback facility is at the digital side of the delta-sigma converters and loops analog transmit data back to the analog receive path. The second ana-log loopback is at the PCM bus interface and loops the transmit data from the line back to the receive path. By assigning the transmit and receive time slots identi-cally, a loopback arrangement at the PCM bus can be effectively programmed for signals generated on the line side of the codec. This mode is useful for testing from the line side through the entire device.。

The last 2 digits of this number define the issue status, which starts at 00 and increments through 01, 02, 03, etc. as the PCB is updated. Some issue PCBs never reach full production status and are therefore not included in this manual. A let-ter following the 10 digit IPN has no relevance in identifying the PCB for service purposes.Note:It is important that you identify which issue PCB you are working on so that you canrefer to the appropriate set of PCB information.Parts ListsThe 10 digit numbers (000-00000-00) in this Parts List are “internal part numbers” (IPNs). Your spare parts orders can be handled more efficiently if you quote the IPN and provide a brief descrip-tion of the part.The components listed in this parts list are divided into two main types: those with a circuit refer-ence (e.g. C2, D1, R121, etc.) and those without (miscellaneous and mechanical).Those with a circuit reference are grouped in alphabetical order and then in numerical order within each group. Each component entry comprises three or four columns, as shown below:The miscellaneous and mechanical section lists the variant and common parts in IPN order.Variant ComponentsA variant component is one that has the same circuit reference but different value or specification in different product types. Variant components are indicated by a character prefix such as “&”, “#” or “=”.circuit reference -lists components in alphanumeric ordervariant column -indicates that this is a variant component which is fitted only to the product type listed Internal Part Number -order the component by this numberdescription -gives a brief description of the componentGrid Reference IndexTo assist in locating components and labelled pads on the PCB layouts and circuit diagrams, a com-ponent grid reference index has been provided. This index lists the components and pads in alpha-numeric order, along with the appropriate alphanumeric grid references, as shown below:Using CAD Circuit DiagramsReading a CAD circuit diagram is similar to reading a road map, in that both have an alphanumeric border. The circuit diagrams in this manual use letters to represent the horizontal axis, and num-bers for the vertical axis. These circuit diagram “grid references” are useful in following a circuit that is spread over two or more sheets.When a line representing part of the circuitry is discontinued, a reference will be given at the end of the line to indicate where the rest of the circuitry is located. The first digit refers to the sheet number and the last two characters refer to the location on that sheet of the continuation of the circuit (e.g.1-D4).If more than one line is represented (indicated by a double thickness line), a dot with a reference label will follow the route each individual line represents.circuit diagram reference PCB layout referencecomponents listed in alphanumeric orderlayer number -1 = top side layer 2 = bottom side layercomponent location on the layersheet numbercomponent location on the sheet。
