CIRCUIT ANALYSIS 7.3.2.1 Oscillator For Ethernet PHYs This circuit consists of crystal oscillator circuit Y1 powered by 3.3 V applied to Y1, Pin 4, Vcc. Oscillator circuit Y1 is biased on by resistor R49 connected to Y1, Pin 3, CTRL and produces 25 MHz on the output at Pin 3 through resistor R51 (OSC 25MHz). This output connects to the CLK25 inputs to the Ethernet 10 and Ethernet 10/100 Mbit PHYs3. 7.3.2.2 JTAG Port This JTAG PORT circuit consists of buffer U1 (NC7SZ125M5).
CIRCUIT ANALYSIS for about 0.4 sec. U40-3 is inverted by U41. During the high part of the cycle, the resulting low at U41-4 holds the HSC ON pin low keeping the HSC OFF. When U40-3 switches low, U37-2, the HSC ON pin is allowed to go high through D35, pulled up by resistor R157. The HSC turns ON, but if the fault is still present, it turns OFF within 40µs and the cycle continues. If the fault is gone, the 555 is held reset and the Controller Board resumes normal functioning.
CIRCUIT ANALYSIS 7.3.2.9 Decouplers Decoupling capacitors (Decouplers) are used to eliminate high-speed transient noise in high-speed digital circuits. There are many decoupling capacitors used on the Controller Board. These capacitors are connected between a source and ground. For example, on sheet 3 of Schematic Diagram WD-CB101069V1 there are two 3.3V decoupling capacitors, C2 and C87. 7.3.
CIRCUIT ANALYSIS for an input to the base of NPN transistor Q9/Q10. Transistors Q9/Q10 are used to convert the RX level from 5V to 3.3V. The output of Q9/Q10 (RXA/RXB) is applied at 3.3V to the microprocessor. When the input (BKP-BSL0/BSL1) is high, diode D23/D25 is reversed biased making the input to U23A/U23B high and the output on the collector of Q9/Q10 also high. When the input is low, diode D23/D25 is forward biased and the input to U23A/U23B is low. The output on the collector of Q9/Q10 is also low.
CIRCUIT ANALYSIS 5.0V 5.0V EPLD BACKPLANE Figure 6 - Input Circuits U22A, E, F, U29D and U32B The FSL output from the EPLD to the backplane is connected through inverter circuit U33A and FET Q2 (BKP-FSL). The RX-MUTE output from the EPLD to the backplane is connected through Inverter U33D and transistor circuit Q1 (BKP-RX_MUTE). The EMSQTOAV output from the EPLD to the backplane is accomplished through Inverter U35C and transistor circuit Q6 (BKP-EMSQTOAV).

The 8-bit data bus is connected to the 32-bit processor data bus via an 8-bit transceiver.
CIRCUIT ANALYSIS predetermined "start-up" information on the microprocessor data bus during RESET. The microprocessor reads the data bus state just before RESET goes inactive (high) and uses the result for start-up initialization. At power up, the MPC860 samples the data bus and the MODCK bits to obtain the Hardware Configuration Word and clock setup parameters respectively.
CIRCUIT ANALYSIS Real Time Clock (RTC) A battery backed up Real Time Clock, U43, is provided to retain the elapsed time even with power off. U43 can be read or written via the I2C bus. The slave address for U43 is D0 hex. Accurate timing is maintained by 32.768kHz crystal Y5. Processor U9 has an internal real time clock, however it consumes too much power to allow battery back up. Therefore the real time is read from U43 via the I2C bus at power up and stored in the processors RTC.
CIRCUIT ANALYSIS Access to various board inputs/outputs is made available through Electronically Programmable Logic Device (EPLD) U27. The EPLD contains numerous read/write latches with a simple 8-bit interface to the microprocessor. The EPLD is in-circuit programmable via the JTAG port using an Altera Byte-blaster cable. A 10-Pin header J10 is made available for this purpose. The EPLD JTAG port is also brought to microprocessor I/O pins to allow the microprocessor to load the EPLD configuration.
CIRCUIT ANALYSIS 7.3.8 I2C Bus The I2C-bus is a two-wire serial bus (SCL and SDA) used for microcontroller-based control. The I2C Bus circuits, for the Controller Board, are shown on Schematic Diagram WD-CB101069V1, Sheet 14. These circuits consist of Personality EEPROM U14 and 8bit I/O expanders for the I2C bus U15 and U26. EEPROM U14 provides 16k of non-volatile data storage. EEPROM U14 is organized as 16kx8 and is accessible via the I2C port of microprocessor U9.

CIRCUIT ANALYSIS 7.4 SitePro MODEM BOARD The SitePro Modem Board contains three synchronous serial ports (modems) and a local microprocessor. This board plugs into the Controller Board using two connectors, QUICC (J9) and I/O (J2). Refer to Figure 9 - Site Pro Modem Board Block Diagram. The microprocessor interface is a simple 8-bit bus port with two separate chip selects. One chip select controls access to an 8k x 8 dual port RAM.

CIRCUIT ANALYSIS In this case, the outputs are always enabled, so the OE/ pins are tied low. Section 1 is used for signals which only go from the microprocessor to the Modems, so Pin 1 (1DIR) is tied high. Section 2 is used for the bi-directional bus. Pin 24 (2DIR) is driven by logic which sets the direction from microprocessor to Modems (high) most of the time. Only during a read of one of the modems is the direction reversed (low). 7.4.3 Microprocessor The 80C323 microprocessor is a 3.
CIRCUIT ANALYSIS will not try to access U2 at the same time causing bus contentions. During loading, bus transceivers U12 (address bus) and U13 (data bus) are turned on. They are held inactive at all other times by the same RESETIN/ signal. The QUICC controls Code memory access through signals RESETIN/, R/WL/, CODECS/ and CODE_A16. While RESETIN/ is held low, the QUICC can write or read U2. CODE_A16 can be used to control which 64K byte half of U2 is used.
CIRCUIT ANALYSIS 7.6.1 Quad ADC and Single DAC AD/DA Converter U23 is an 8-bit CMOS data acquisition device with four analog inputs, one analog output and a serial I2C-bus interface. Three address pins A0 (Pin 5), A1 (Pin 6) and A2 (Pin 7) can be used for programming a hardware address, allowing up to eight similar devices to be connected to the I2C-bus without additional hardware. In this application, these three leads are tied to +5V.
CIRCUIT ANALYSIS 7.6.3 –5 Volt Generation -5 Volt generation is accomplished through voltage regulator U2. –12 Volts is applied to U2, Pin 4 IN. Capacitors C3 and C4 provide filtering of this input. The output is at U2, Pin 3 Out. The –5 Volts is filtered by capacitors C5 and C6. –5Volts can be monitored at Test Point TP31. 7.6.

The output of U5D, Pin 14 is applied to the input of 8:1 MUX U7, Pin 5 (N02). This HSD amplifier filter output can be monitored at TP5. Table 11 - 4800 Baud NB Filter Response FREQUENCY 7.6.4.
CIRCUIT ANALYSIS 7.6.4.5 9600 Baud Narrow Band This HSD filter circuit consists of switched-capacitor filter circuit U11 required to produce a narrow frequency response. This circuit is driven by an external 400 kHz clock on U11, Pin 1. The output on U11, Pin 5 is applied to the input of 8:1 MUX U7, Pin 12 (N05). This HSD filter circuit output can be monitored at TP8. Table 14 - 9600 Baud NB Filter Response FREQUENCY 7.6.4.
CIRCUIT ANALYSIS 7.6.4.8 Inverting Buffer/Amplifier Amplifier circuit U6B is an inverting buffer/amplifier with a gain of approximately 1.5. The output of this circuit is connected to the input of analog switch U9. The output of this circuit can be monitored at TP9. 7.6.4.9 Analog Switch Analog Switch U9 is a Single-Pole/Double Throw (SPDT) with one normally closed and one normally open switch.
CIRCUIT ANALYSIS in parallel with R60. When Pin 6 is high R67 has been removed from the circuit. Moving R67 in and out of the circuit adjusts the input time constant to U12B, Pin 6. Voltage comparator U12B provides a square wave output that swings from +12 to -12 volts, monitored at TP14. This output is applied through resistor R58 to the base of NPN transistor Q1. Transistor Q1 interfaces the limited signal LSIN to the Controller Board.
CIRCUIT ANALYSIS Low-Speed Data is generated by microcomputer U1 on the Modem Board through EPLD U27, Pins 81 and 80, Walsh Bit 1 and Walsh Bit 2 respectively. For low-speed data, the two Walsh bits are scaled by resistors R91 and R95 and summed through analog switch U22. The output of U22, Pin 1 (D) connects through operational amplifier U19A and buffer/follower U19B to the input of the low-speed-data encode filter U20. Operational amplifier U19A produces a loss of -9 dB at TP23.

TROUBLESHOOTING Troubleshooting information: The receive path is J7-A27 to U36-9 at RS232 level, out U36-20 at 3.3V level, to QUART U28-27, echoed out U28-28 to U36-23, and out U36-6 to J7-A28 at RS232 level. 9.4.3.17 BSL TEST Procedure: Loop BSL0 to BSL1 and run FactoryTest test 11, subtest 1. Troubleshooting information: +12V must be present for the BSL circuits. Two separate tests are run; first BSL0 to BSL1 then BSL1 to BSL0. Two ports of QUART U28 are used. Port A receives and transmits on BSL0.
TROUBLESHOOTING on J7-A21. This RS232 signal comes in to U24-6, gets converted to 3.3V levels at U2417 and goes to SCC3RX on U1 (not accessible). The 860 processor U1 (not accessible) echoes characters out SCC3TX at 3.3V level and drives RS232 converter U24-14. U24-9 drives out to the card edge (J7-A22) at RS232 levels. 9.4.3.20 TEST SMC2 Procedure: Connect terminal to J14H on rear of shelf. Set terminal for 38.4kbd, N81. Type a few characters and observe characters echoed to terminal.

TROUBLESHOOTING 9.4.3.24 I/O INPUTS TEST - GROUP A Procedure: To test inputs, it is necessary to apply 5V (through a 10K resistor) or ground to the input point. Then execute a FactoryTest Command Mode READ command. The table shows the command and expected result for both 5V input and ground input. The READ command presents values in hex. Convert the hex to binary to see the individual bits.
TROUBLESHOOTING for the other 3 inputs are read by the software by executing a FactoryTest Command Mode READ command. The table shows the commands and expected result for both 5V input and ground input.
TROUBLESHOOTING Jumper VDIRTS to VDICTS, J14B-6 to J14B-7 on the shelf rear. Then execute FactoryTest test 16. Troubleshooting information: Upon command of the 860 processor, PLRTS is generated in the PLD and exits U27-65. It is buffered, inverted and converted to RS232 levels by U13, entering U13-11, exiting U13-14. It exits the board on J7-B18. PLRTS is looped back to the Controller board into PLCTS on J7-B17. It is converted to TTL, buffered and inverted by U13, entering U13-13 and exiting U13-12.
TROUBLESHOOTING or missing. Use a known good Modem board. Check for 11.0592 MHz clock at Modem Board U9-16. Procedure: Instead of following the on screen directions, observe TXC_MISSING_ALARM at J1318. The test requires an external pullup resistor. Remove the 9.6REF signal. TXC_MISSING_ALARM should go high. Troubleshooting information: TXC_MISSING_ALARM is generated inside the PLD if 9.6REFIN is missing. 9.6REFIN must get to the PLD via the path described above.
TROUBLESHOOTING Modem Board. A working Modem board must be present and not reset for this test. The FSL signal exits the PLD at U27-113. It is buffered and inverted by U33, entering at U33-1, exiting U33-2 which drives FET driver Q2. The FET drives a +12V to 0V signal to J7-C30. The FSL output is capable of driving a 50 ohm load resistor pulled to +12V. 9.4.3.31 EEPROM VERIFY TEST Procedure: After turning power off for a few seconds, then back on, execute FactoryTest test 8, subtest 2.
TROUBLESHOOTING 9.4.4.5 TEST 5 - LOW SPEED DECODE FILTER Sine wave input 100Hz at 1VPP at VOLSQHI is buffered by U15A (seen at TP13), amplified about 2:1 in U15B (seen at TP15), passes through high pass filter U16 (seen at TP16), then through low pass filter U14 (seen at TP17), through amplifier (gain = 2) U28A (seen at TP18). The frequency response is measured at TP18 before going to nonlinear circuits. U12B is a slicer, which converts the waveform to a square signal at TP14.
TROUBLESHOOTING 150Hz input is selected by mux U22 which is controlled by LSCTL. This signal is derived from I2C I/O expander U4 (TP30) and must be logic 1 (5V) to select the 150HZ input. The signal then passes through amplifier U19A where it is reduced in level by about a factor of 4 as seen at TP23. It then goes through buffer U19B (seen at TP22). Then through low pass filter U20 (seen at TP21) then through final amplifier/buffer U17A. Filtered output is seen at LSDTX.
TROUBLESHOOTING Two terminal emulators are required. Refer to the Shelf test. Load SIMON into the Modem Board. Select the filter with I2C commands SI2C 4C 01 02 WI2C 00 00 (for filter 0) WI2C 01 00 (for filter 1) Etc. Set digital pot level with I2C commands SI2C 50 01 00 WI2C A9 50 (for pot level of 50 hex) The command ‘W RX_CTRL 0X00’ may also be needed to set up connections in the PLD. Run the RF BER test as described in the shelf test to produce data through the High Speed filters.
TROUBLESHOOTING 9.4.4.9 TEST 11 - 9600 BAUD WIDE BAND ETSI HS FILTER Same as test 10 except filter 1 (9600 Baud Wide Band ETSI) is selected by mux U7. HS_FILTER_SEL0 is logic 1 and the other two are logic 0. See test 10 for levels. 9.4.4.10 TEST 12 - 4800 BAUD NARROW BAND HS FILTER Same as test 10 except filter 2 (4800 Baud Narrow Band) is selected by mux U7. HS_FILTER_SEL1 is logic 1 and the other two are logic 0. See test 10 for levels. 9.4.4.
TROUBLESHOOTING 9.4.4.16 TEST 18 - RS232 TO RS485 CONVERSION OF PLTXCLK In the shelf, a 9600Hz RS232 level clock is always present at PLTXCLK. U24 converts it to TTL at U24-9. This signal is fed to RS485 converter U25 at U25-7. Connect a 100 ohm load across PLTXCLK+ to PLTXCLK-.A differential signal of several volts should be seen across PLTXCLK- to PLTXCLK+ (J13-9 to 10). 9.4.4.
