The IC supply voltage is derived from the line via a dropping resistor and regulated by the UTC TEA1062/1062A,The supply voltage Vcc may also be used to supply external circuits e.g. dialling and control circuits. Decoupling of the supply voltage is performed by a capacitor between Vcc and V EE while the internal voltage regulator is decoupled by a capacitor between REG and V EE. The DC current drawn by the device will vary in accordance with varying values of the exchange voltage(V exch ), the feeding bridge resistance(R exch ) and the DC resistance of the telephone line(R line ). The UTC TEA1062/1062A has an internal current stabilizer operating at a level determined by a 3.6k ¦¸ resistor connected between STAB and VEE( see Fig.8). When the line current(I line )is more than 0.5 mA greater than the sum of the IC supply current ( Icc) and the current drawn by the peripheral circuitry connected to V CC (l p ) the excess current is shunted to V EE via LN. The regulated voltage on the line terminal(V LN ) can be calculated as: V LN =V ref +I SLPE *R9 or;V LN =V ref +[(I line – I CC - 0.5*10-3A)£-I p ]*R9where:V ref is an internally generated temperature compensated reference voltage of 3.7V and R9 is an external resistor connected between SLPE and V EE . In normal use the value of R9 would be 20Ω. Changing the value of R9 will also affect microphone gain, DTMF gain,gain control characteristics, side tone level,maxmimum output swing on LN and the DC characteristics (especially at the lower voltages). Under normal conditions, when I SLPE>=I CC +0.5mA +I p , the static behaviour of the circuit is that of a 3.7V regulator diode with an internal resistance equal to that of R9.In the audio frequency range the dynamic impedance is largely determined by R1.Fig.3 shows the equivalent impedance of the circuit.Microphone inputs(MIC+ and MIC-) and gain pins (GAS1 and GAS2)The UTC TEA1062/1062A has symmetrical inputs.Its input impedance is 64k Ω (2*32k Ω) and its voltage gain is typically 52 dB (when R7=68k Ω.see Fig.13).Dynamic, magnetic, piezoelectric or electret (with built-in FET source followers) can be used. Microphone arrangements are illustrated in Fig.10. The gain of the microphone amplifier can be adjusted between 44dBand 52dB to suit the sensitivity of the transducer in use.The gain is proportional to the value of R7 which is connected between GAS1 and GAS2. Stability is ensured by the external capacitors, C6 connected between GAS1 and SLPE and C8 connected between GAS1 and VEE. The value of C6 is 100pF but this may be increased to obtain a first-order low-pass filter.The value of C8 is 10 times the value of C6. The cut-off frequency corresponds to the time constant R7*C6.Mute input (MUTE)A LOW(UTC TEA1062 is HIGH) level at MUTE enables DTMF input and inhibites the microphone inputs and the receiving amplifier inputs; a HIGH(UTC TEA1062 is LOW) level or an open circuit does the reverse. Switching the mute input will cause negligible clickis at the telephone outputs and on the line. In case the line current drops below 6mA(parallal opration of more sets) the circuit is always in speech condition independant of the DC level applied to the MUTE input.Dual-tone multi-frequency input (DTMF)When the DTMF input is enabled dialling tones may be sent onto the line. The voltage gain from DTMF to LN is typically 25.5dB(when R7=68k Ω) and varies with R7 in the same way as the microphone gain. The signalling tones can be heard in the earpiece at a low level(confidence tone).Receiving amplifier (IR,QR and GAR)The receiving amplifier has one input (IR) and a non-inverting output (QR). Earpiece arrangements are illustrated in Fig.11. The IR to QR gain is typically 31dB (when R4=100k Ω). It can be adjusted between 20 and 31dB to match the sensitivity of the transducer in use.The gain is set with the value of R4 which is connected between GAR and QR.The overall receive gain,between LN and QR, is calculated by substracting the anti-sidetone network attenuation (32dB) from the amplifier gain. Two external capacitors, C4 and C7,ensure stability. C4 is normally 100pF and C7 is 10times the value of C4. The value of C4 may be increased to obtain a first-order low-pass filter.The cut-off frequency will depend on the time constant R4*C4.The output voltage of the receiving amplifier is specified for continuous-wave drive. The maximum output voltage will be higher under speech conditions where the peak to RMS ratio is higher.UTC TEA1062/1062A LINEAR INTEGRATED CIRCUITUTC UNISONIC TECHNOLOGIES CO., LTD.7QW-R108-001,AAutomatic gain control input(AGC)Automatic line loss compensation is achieved by connecting a resistor(R6) between AGC and V EE . The automatic gain control varies the gain of the microphone amplifier and the receiving amplifier in accordance with the DC line current. The control range is 5.8dB which corresponds to a line length of 5km for a 0.5mm diameter twisted pair copper cable with a DC resistance of 176Ω/km and average attenuation of 1.2dB/km. Resistor R6 should be chosen inaccordance with the exchange supply voltage and its feeding bridge resistance(see Fig.12 and Table 1). The ratio of start and stop currents of the AGC curve is independent of the value of R6. If no automatic line loss compensation is required the AGC may be left open-circuit. The amplifier, in this condition, will give their maximum specified gain.Side-tone suppressionThe anti-sidetone network, R1//Z line , R2, R3, R8, R9and Z bal ,(see Fig.4) suppresses the transmitted signal in the earpiece. Compensation is maximum when the following conditions are fulfilled:(a) R9*R2=R1[R3+(R8//Z bal )];(b) [Z bal /(Z bal +R8)]=[Z line /(Z line +R1)];If fixed values are chosen for R1, R2, R3 and R9 then condition(a) will always be fullfilled when R8/Z bal l ¡¶R 3.To obtain optimum side-tone suppression condition(b)has to be fulfilled which results in:Z bal =(R8/R1) Z line =k*Z line where k is a scale factor;K=(R8/R1).The scale factor (k), dependent on the value of R8, is chosen to meet following criteria:(a) Compatibility with a standard capacitor from the E6 or E12 range for Z bal,(b)£üZ bal //R8£ü¡¶R 3 fulfilling condition (a) and thus ensuring correct anti-sidetone bridge operation,(c) £üZ bal +R8£ü¡·R 9 to avoid influencing the trans- mitter gain.In practice Z line varies considerably with the type and length. The value chosen for Z bal should therefore be for an average line length thus giving optimum setting for short or long lines.ExampleThe balance impedance Z bal at which the optimum suppression is present can be calculated by: Suppose Z line = 210Ω+(1265Ω//140nF) representing a 5km line of 0.5 mm diameter, copper, twisted pair cable matchedto 600Ω(176Ω/km;38nF/km). When k=0.64 then R8=390Ω,Z bal =130Ω+(820Ω//220nF). At line currents below 9mA the internal reference voltage is automatically adjusted to a lower value(typically 1.6V at 1mA) This means that more sets can be operated in parallel with DC line voltages (excluding the polarity guard) down to an absolute minimum voltage of 1.6V.With line currents below 9mA the circuit has limited sending and receiving levels. The internal reference voltage can be adjusted by means of an external resistor(R VA ). This resistor when connected between LN and REG will decrease the internal reference voltage and when connected between REG and SLPE will increase the internal reference voltage. Current(I p )available from V CC for peripheral circuits depends on the external components used. Fig.9 shows this current for V CC > 2.2V. If MUTE is LOW (1062 is HIGH)when the receiving amplifier is driven the available current is further reduced. Current availability can be increased by connecting the supply IC(1081) in parallel with R1,as shown in Fig.16(c), or, by increasing the DC line voltage by means of an external resistor(R VA )connected between REG and SLPE.UTC TEA1062/1062A LINEAR INTEGRATED CIRCUITUTC UNISONIC TECHNOLOGIES CO., LTD.8QW-R108-001,ALNV EEµFCCRp=16.2k ΩLeq=C3*R9*RpFig.3 Equivalent impedance circuitThe anti-sidetone network for the UTCTEA1062/1062A family shown in Fig.4 attenuates the signl received from theline by 32 dB before it enters the receiving amplifier.

The Actel Fusion Programmable System Chip (PSC) improves the design of MicroTCA power modules by dramatically reducing part count, board space, system cost, and power while increasing reliability, flexibility, and system availability.The Fusion device includes analog I/O, an analog-to-digital converter, FPGA gates, large Flash memory,clocking, and other features that enable it to reduce the part count of the Actel Power Module (PM) reference design by hundreds of parts over other FPGA- and MCU-enabled power modules. The analog I/O, digital processing of analog signals, and Flash memory enable improved system monitoring and control so that systemreliability and availability increases. As an FPGA, Fusion is the most flexible solution on the market, with in-system reprogrammable microcode and FPGA logic gates.Finally, Fusion improves performance with many functions coprocessed in FPGA gates alongside the Core8051 processor.Actel has reduced the part count required for MicroTCA power module designs in a unique reference design platform that includes hardware, software, and FPGA hardware description language (HDL)—a full solution.Unlike component-driven ASSP designs, the Actel Fusion FPGA enables integration of multiple functions, which include voltage and temperature monitoring, a large Flash memory for event logging, and nonvolatile FPGA fabric for nearly instantaneous hot-swap and power switchover. All of this functionality is delivered today with an Actel Fusion chipset while reducing your bill-of-materials cost over ASSP-based power module systems.Figure 2•Power Module Fusion Device Block DiagramMicroTCAProduct Brief3The Actel Power Module reference design functions as described in the MicroTCA Specification v1.0, Chapter 4,and provides all of the power subsystem functionality,including the following:•Modular inputs •Fusing•Supply selection •Emissions filtering•Transient suppression and power conversion •Payload and management power monitoring•Power supply to the MicroTCA Carrier Hubs(MCH), AMCs, and cooling unitThe power module reference design includes the redundant Intelligent Platform Management Bus (IPMB-0)and the optional JTAG interfaces.The reference design also includes functionally verified hardware, FPGA HDL, and third-party software support.All elements of the design will be thoroughly tested during MicroTCA interoperability testing.For those who want to customize the design, Actel provides the source and can enable a path for turn-key modifications. Signal Stream Technologies has partnered with Actel to offer design services for customizing both hardware and software and will deliver timely engineering support and maintenance services. The Actel Protocol Design Services group can provide modifications to the HDL . For modules in production volume, our partner, MicroBlade™, Inc., offers complete turn-key power modules to your exact specifications. In summary,you can customize the design yourself or have Actel and its partners perform customization.The power module reference design is delivered as a single-board design for the smallest form factor and superior thermal capabilities.Unlike MCU-based designs, which are software-driven and slow, many functions, such as analog-to-digital conversion sequencing and sampling, over-current and under-voltage power switchover, and hot-swap disable,are hardwired. Hardwired fail-safe logic minimizes response time, if there is an unexpected board extraction or system failure.Since payload power current regulation is fully implemented in hardware, the Actel power module is more accurate than MCU-based designs. The current limit for each output channel can be individually programmed in 256 steps with ±1% full-scale accuracy.L ikewise, both payload power and management power output voltages are measured with ±1% full-scale accuracy.The power module is also more flexible than anything on the market today. A customer can update the FPGA firmware and application software on-the-fly and can customize hardware, firmware, or software. With a total of 1MByte of on-board Flash memory, software for the on-chip Core8051 microcontroller can be reprogrammed on-the-fly by uploading code to an isolated buffer in theFlash memory, performing verification, and then switching the context to the new software. Unlike an ASSP-based solution, the Actel controller is an FPGA, so even the "hardware" is reprogrammable, either on the bench using standard FPGA programming tools or in-system via the MicroTCA backplane JTAG interface. A customer can also add differentiation to the hardware design, since Actel provides a full set of design documents, including schematics, a bill-of-materials,layout drawings, and manufacturing drawings.A Power Module That Goes Beyond the MicroTCA StandardThe Actel MicroTCA power module is a reference module designed specifically to meet the power conversion,power switching, and form factor requirements to enable MicroTCA applications.It supports a dual –48 VDC input and delivers more than 380W to the MicroTCA backplane. With the revolutionary form factor made available by the Actel Fusion device, power output levels greater than 700W are easily possible in a single power module.The monitoring and controller hardware supports input power filtering, conditioning, fusing and monitoring,output power control, monitoring and protection, and DC-to-DC conversion for management and payload power. The Intelligent Platform Management Interface (IPMI) software is IPMI v2.0 compatible and will manage the turn-on sequencing for local AMCs, voltage, and current monitoring, handle abnormal power conditions,and respond to commands and requests from an MCH via the IPMB-0 interface. The module works with a single or dual MCH or as a standalone device without an MCH present in the system. It is compatible with the new PICMG ® MicroTCA.0 revision 1.0 standard.The module can turn on each of the management and payload power lines individually, as specified in the MicroTCA specification. It also monitors temperature and power status and reports this back to the MCH. In the case of no MCH, the microcontroller on the module notices that no MCH is present and can execute an on-board preprogrammed system management application.If an AMC is inserted, the power for that slot is turned on and if a module is extracted, the power for that slot is turned off. System application software can be downloaded to the board using the serial port (RS-232)on the front of the module or by the JTAG interface. The IPMB bus on the power module will also monitor temperature and handle fan speed on the cooling module, when that reference design is available.IPMI Debug and Self-TestThis power module allows the user to record and insert IPMI commands into any of the I2C busses in the system.This feature is useful for development, debugging, and testing of a system.MicroTCA4Product BriefTechnical SpecificationsGeneral•Single-wide / full-height per AMC.0 revision 1.0•384 W with typical power dissipation under full load of 28.3W•93% total efficiency •Component part count–Less than 400 total parts –65 stock-keeping units•Payload and management brick temperature monitors•Inlet air temperature monitorSystem Management•Single-cycle, 8-bit, Core8051 MCU in an Actel Fusion FPGA•Fusion: 1,024 kilobytes of Flash, 216 kbits of RAM •Analog monitoring and A/D conversion •IPMI v2.0 for power module EMMCPower Inputs•< 415 W•–36 to –72 VDC at 15 A maximum•Power inputs are transient protected and fused •Input voltage is monitored and event messages are generated for alarm conditionsPower Outputs•384 W output with a 1/2 brick•800 W output possible with two 1/4 bricks•Support for all MicroTCA specified redundancy configuration•Supports total payload power output channel on resistance as low as 3.4 m Ω •Payload power channel outputs –±50 mV resolution–Over-voltage monitored with configurablethreshold–Under-voltage monitored with configurablethreshold–Backup trigger threshold voltage configurable –Default current limit 7.6 A–Programmable from 200 mA to 9.7 A in 50mAincrements–Current threshold accuracy ±50 mA–Immediate current limit engages in less than60µs for over-currents greater than 105% of threshold–Warnings for over-currents greater than 100%and less than 105%•Management power channel outputs –±25 mV resolution–Over-voltage monitored with configurablethreshold–Under-voltage monitored with configurablethreshold–Backup trigger threshold voltage configurable –Current limited to greater than 150 mA andless than 225 mA•Standby management power output/input–Output current greater than or equal to350mA–Input current less than or equal to 225 mACompliance•Conforms to PICMG MicroTCA specification v1.0 /IPMI v2.0 (subject to verification)•RoHS compliant•Designed to meet or exceed (subject to verification testing)–Safety: UL 1950, UL 94, CSA 22.2 No. 950, EN60950, IEC 950–EMI/EMC: EN 55022 / EN 55024, EN 50081-1 / EN6100-6-2Front Panel•AMC latch with hot-swap switch •Blue hot-swap indicator LED •Green ready indicator LED•Red out-of-service indicator LED•Green/Amber (LED) indicating IPMI Tx/Rx message traffic•USB diagnostic port•A andB power input connectorsEnvironmental•Environment per PICMG MicroTCA.0 revision 1.0•Operating temperature: –5°C to 40°C long-term ––5°C to 55°C for 96 hours–Storage temperature: –40°C to 70°C–Operating humidity: 5% to 95% relativehumidity (non-condensing and condensing)Miscellaneous•Dimensions: 186.7 × 73.2 × 30.5 mm •Weight: less than 300 g •MTBF: TBDMicroTCAProduct Brief 5IPMI CommandsMicroTCA Power Module EMMCIPM Device "Global" CommandsGet Device ID Get Self Test Results Broadcast "Get Device ID"PEF and Alerting CommandsGet PEF Capabilities Arm PEF Postpone TimerSet PEF Configuration Parameters Get PEF Configuration Parameters Set Last Processed Event ID Get Last Processed Event IDSensor Device CommandsGet Device SDR Information Get Device SDRReserve Device SDR Repository Get Sensor ReadingFRU Device CommandsGet FRU Inventory Area Information Read FRU Data Write FRU DataSDR Device CommandsGet SDR Repository Information Reserve SDR Repository Get SDR Add SDR Partial Add SDR Clear SDR Repository Get SDR Repository Time Set SDR Repository TimeExit SDR Repository Update ModeSEL Device CommandsGet SEL Information Get SEL Entry Add SEL Entry Partial Add SEL Entry Clear SEL Get SEL Time Set SEL TimeAdvancedTCAGet PICMG Properties FRU ControlGet FRU LED Properties Get LED Color Capabilities Set FRU LED State Get FRU LED State Set IPMB StateGet Device Locator Record ID Set Port StateFRU Control CapabilitiesAdvancedMCSet AMC Port State Get AMC Port StateMicroTCAPower Channel Control Get Power Channel Status PM Reset Get PM Status PM HeartbeatReference Design Kit Contents•Hardware –Schematic –BOM–Manufacturing files •IP platform (FPGA HDL)–Object code: Netlist or obfuscated RTL –Source code: RTL source •Application software–Object code: compiled source code –Source code: in C languageOrdering InformationTable 1•Ordering CodesPart NumberDescriptionMicroTCA Power Module Reference Design uTCA-PM-RD-O With object code uTCA-PM-RD-SWith source codeMicroTCA Power Module uTCA-PM-SAStandalone power moduleMicroTCADatasheet CategoriesIn order to provide the latest information to designers, some datasheets are published before data has been fully characterized.

The STK525 shouldprovide a 5V power supply over the VBUS pin of its USB mini AB connector.A couple of transistors on the STK525 allows the UVCON pin of the AT90USBxxx tocontrol the VBUS generation (See Figure2-4). In this mode the STK525 is powered byexternal power supply source (J6 or STK500 expand0/1 connectors). JP7 allows toselect the 5V source used by the VBUS generator.Figure 2-4 .
