3-2. Circuit Description

DM-140 BoardThe DM-140 board demodulates Y, R-Y, B-Y, CAM SYNC, and SKIN GATE signals.The multiplexed signal is separated into power voltage and the RF signal on the IO-214 board. The RFsignal is transferred to the MPX filter on the DM-140 board where the Y RF signal and the CHROMA RFsignal are extracted. These signals are then demodulated to be used as each signal.This board consists of cable length detector circuit, cable compensation circuit, and their demodulatorcircuit.The cable length is detected from the amplitude of Y modulation wave. Then compensation of amplitudeand phase in accordance with respective Y and color difference modulation waves is carried out in thecable compensation circuit. These signals are then demodulated in the demodulator circuit.

Cable Compensation CircuitThis circuit comprises 4-stage phase equalizers and amplifiers for compensation of Y, R-Y, and B-Ymodulation waves respectively to compensate attenuation or phase delay of modulation waves due tocables. When the comparator circuit judges Y compensation circuit output level as insufficient compensa-tion, the compensation amplifier is activated to amplify the output level. As long as insufficient compen-sation continues, further compensation is added until signals become adequate.The R-Y or B-Y compensation circuit, with the same structure as the Y compensation circuit, compen-sates each signal by interlocking with the Y compensation circuit.

Cable Length Detector CircuitThis circuit determines whether the amplitude of Y compensation circuit output is adequate for demodu-lation or not. If inadequate, this circuit controls the Y, R-Y, and B-Y compensation circuits to add furthercompensation. In order to determine whether compensation is adequate or not, this circuit amplifies the Ycompensation circuit output, peak-holds the output amplitude, and then compares the DC value with thereference voltage. If the amplitude is inadequate level, this circuit adds further compensation to the signalby controlling applicable compensation circuit.

Y Demodulator CircuitThe Y signal is demodulated by the demodulator using a carrier whose phase is the same as the Y modu-lation wave. The demodulated Y signal passes through the amplifier and the buffer, and is then trans-ferred to the low pass filter (LPF) where the signal is clamped and output after its unnecessary 22.5 MHzcarrier component is eliminated. The CAM SYNC and SKIN GATE signals are also demodulated in thesame way by a carrier whose phase is different (by 90 degrees) from the Y signal.

Color Difference Signal Demodulator CircuitThe B-Y color difference signal is demodulated by the demodulator using a carrier whose phase is thesame as the B-Y modulation wave. The demodulated B-Y signal passes through the amplifier and thebuffer, and is then transferred to the LPF where the signal is clamped and output after its unnecessary 45MHz carrier component is eliminated. The R-Y signal is also demodulated in the same way by a carrierwhose phase is different (by 90 degrees) from the B-Y signal.


TR-133 BoardThe TR-133 board demodulates the RF signals of MIC1, MIC2, INCOM, CAM DATA, and TONEtransmitted from the camera, and modulates the PGM, INCOM, CCU DATA, and H CONT signals totransmit them to the camera. In addition, this board also modulates RETURN VIDEO and PROMPTVIDEO (and AUX VIDEO as well by selection).

H CONT Modulator CircuitThis circuit modulates the H CONT signal transferred from the IV-57 board. H CONT is a control signalto match the H phases of camera SG and CCU SG. The oscillation frequency varies with the H CONTsignal voltage. The RF signal modulated in the modulator circuit is merged with other RF signals throughthe buffer and the band pass filter (BPF).

CCU DATA Modulator CircuitThis circuit modulates the CCU DATA signal transferred from the AT-155 board. As in the H CONTmodulator circuit, the modulated RF signal is merged with other RF signals through the buffer and the BPF.

INCOM Modulator CircuitThis circuit modulates the INCOM signal transferred from the AU-300 board. As in the H CONT modu-lator circuit, the modulated RF signal is merged with other RF signals through the buffer and the BPF.

CAM DATA/TONE Demodulator CircuitThis circuit has functions for demodulation of the CAM DATA/TONE signals transferred from thecamera to CCU-TX50, shaping the CAM DATA signal waveform, and for TONE detection. The RFsignal whose modulation frequency is 5.6 MHz is demodulated by the FM demodulator IC. The CAMDATA is shaped after the residual carrier is eliminated, and is then sent to the AT-155 board. The TONEsignal transferred to the TONE detector circuit is used to control ON/OFF of 180 VDC supplied fromCCU-TX50 to the camera.

MIC1/2 Demodulator CircuitThis circuit demodulates the MIC1, MIC2 signals transferred from the camera to CCU-TX50. The RFsignal whose modulation frequency is 6.2/6.7 MHz passes through the BPF, and is then demodulated bythe FM demodulator IC. Then the RF signal is output to the AU-300 board after its residual carrier iseliminated.

INCOM Demodulator CircuitThe RF signal whose modulation frequency is 7.1 MHz is demodulated by the FM demodulator IC in thesame way as the MIC signals. It is then output to the AU-300 board through the LPF.

Prompter Modulator CircuitThis circuit performs AM modulation of the VBS signals input from the PROMPT VIDEO connector onthe rear panel, and then sends the signal to the CA. The input VBS signal passes through the buffer, LPF,and the clamp, and is AM modulated by the modulator IC, and is then amplified by the RF amplifier. TheRF amplifier gain is controlled using the compensation data (cable length) provided from the DM-140board. The signal is transferred further to the RF amplifier and the 100 MHz BPF, and is then output.

RETURN Modulator CircuitThis circuit performs FM modulation of the VBS signal input from the RET1 or RET2 connector on therear panel, and then sends the signal to the CA. The input VBS signal passes through the buffer, LPF, andthe clamp, and is then amplified. It is then FM modulated by the modulator IC through the buffer. Themodulation wave gain is also controlled using the cable length data like the prompter modulator circuit.


AU-300 BoardThe AU-300 board outputs the MIC1/MIC2 signals demodulated on the TR-133 board to the rear panel,and sends the PGM signal input from the rear panel to the TR-133 board. The board connects the externalINCOM line and the front panel upon receiving the INCOM signal demodulated on the TR-133 board.The board also functions for TALLY signaling system switchover and external interface.

MIC1/2 Output CircuitThis circuit amplifies the MIC1/MIC2 signals demodulated on the TR-133 board, and outputs the signalsto the XLR-3 connector on the rear panel.The MIC output level can be selected (0 dB or _20 dB) by S18 and S19 in this circuit.

PGM AUDIO1/2 Input CircuitThis circuit amplifies the PGM signal input from the D-sub 25pin connector on the rear panel, andoutputs the signal to the PGM modulator circuit on the TR-133 board.The PGM AUDIO signal is converted from balanced to unbalanced signal by IC204 and IC205. The inputlevel of the signal is selected (0 dB or _20 dB) by S200 and 201.

INCOM Switching CircuitThis circuit switches INCOM lines on the CA side and the CCU-TX50 front panel side. There are threetypes of INCOM lines: PRODUCER line, ENGINEER line (external system), and PRIVATE line isolatedfrom the external system. The switching control signal is sent from the AT-155 board with IIC data, andis input into IC100 that converts the data and turns ON/OFF the analog switches.

External Interface CircuitThis circuit has three types of 2-channel interfaces with external INCOM systems, supporting 2W, 4W,RTS, and Clear Com interfaces. These interfaces are selected by S204, S205, S206, and S207 accordingto the system connected.

External TALLY Signal Input CircuitThis circuit can accept three types of TALLY signal input: contact input, 12 VDC input, and 5 VDCinput. These types of input can be selected independently for RED and GREEN TALLY signals byswitching S1, S2, S3, and S4. Even if actual input signal does not equal the setting, no failure will occur.Furthermore, this circuit is compatible with any signal polarity for 12 VDC and 5 VDC inputs.IC1, IC2, and Q8 to Q11 compose a power circuit for the external TALLY input circuit only, which isground isolated by the transformer T2. The signal output is also electrically isolated by the photocouplerPH1.


IV-57 BoardThe IV-57 board receives the Y, R-Y, and B-Y signals demodulated on the DM-140 board, converts themto digital signals using the 27 MHz clock, and then outputs the digital signals to the EN-156 board. TheSKIN GATE signal from the DM-140 board is also converted to digital signal, is delayed in the PLD, andis then output to the EN-156 board.Furthermore, this board compares the CHU-SYNC signal from the DM-140 board with the H phase ofTG in the PLD, and then outputs it as H-CONT signal to the TR-133 board.

Y/R-Y/B-Y A/D Converter CircuitThe Y, R-Y, and B-Y signals from the DM-140 board pass through the inverter amplifier, LPF, andinverter amplifier where their DC components are fed back and clamped. The signals are then A/Dconverted to 10 bit, 3.3 V p-p parallel signals by IC117 to IC119 with 27 MHz clock input. The R-Y andB-Y signals are then output to the EN-156 board through the D-FF. While the Y signal is delayed in thePLD IC307, and is then output through the D-FF.

SKIN TONE GATE SignalThe SKIN TONE GATE signal from the DM-140 board is input into the D-FF IC107 with 27 MHz clockinput, and is then transferred to the PLD IC307 where the signal is delayed in the same way as the Ysignal. Then the signal is output to the EN-156 board through the D-FF IC121.

H-CONT SignalQ301, Q303, and IC301 on this board detect the H phase of the CHU-SYNC signal from the DM-140board, and transfer it to IC303 where the H signal input from the H timing generator in the PLD IC304 iscompared with the H phase of the CHU-SYNC signal. The difference is output to the TR-133 board as H-CONT signal.


EN-156 BoardThis board generates VBS, PIX, and WFM signals by the D-ENC from the Y, R-Y, and B-Y signals thatare A/D converted using the 27 MHz clock, and converts the signals to analog signals, and then outputsthem. This board also generates, D/A converts, and then outputs the R/G/B signals. The SDI signal is alsooutput through the half-band filter and format encoder.

VBS/WFM/PIX Signal CircuitThe 10 bit, 3.3 V p-p parallel T/R-Y/B-Y signals from the IV-57 board pass through the D-FF (IC102 toIC105), and are then input into the CB generator IC106 where CB output and camera output are switched.The CB output is switched in accordance with respective specifications such as 100 %, 75 %, SMPTE orEIA. The IC106 output is then input into IC326 for digital encoding in which VBS, WFM, PIX, and othersignals are generated. The character signal and the SKIN GATE signal are also mixed at this time. Thegenerated signals are D/A converted, and are then output as analog signals.

Y/R-Y/B-Y, RGB Signal CircuitThe Y, R-Y, and B-Y signals input into IC106 are delayed in the built-in delay circuit to match the phasewith the VBS signal phase. The R/G/B signals are also generated by the built-in matrix circuit. IC106selects which signals (Y/R-Y/B-Y or RGB) to output. The output signals of this IC are converted toanalog signals by IC107 to IC109, and are then output as Y or G signal, R-Y or R signal, and B-Y or Bsignal.

SDI OutputThe Y, R-Y, and B-Y signals from IC106 are input into the half-band filter IC509 to be converted from8:8:8 to 4:2:2 signals. Then the signals are input into IC502 where mixing of the character signals withthe SDI signal, mixing of the SKIN GATE signal are carried out. The signals are encoded to the SDIsignal format, and are then output. The signals are converted from parallel to serial signals by IC503 andIC504, and are then output as SDI signals.

Subcarrier Genlock CircuitIC326 perform subcarrier genlock synchronization. The SC digital data from IC326 is D/A converted byIC301, and is then input into the phase comparator IC306. The subcarrier signal of the external syncsignal and the sync signal are also input into IC306 to compare their phases. The difference passesthrough the burst gate, is A/D converted by IC311, and is then re-input into IC326 where subcarriergenlock synchronization is carried out.


AT-155 BoardProvided with a microcomputer (SH2), the AT-155 board controls the boards and the power supply unitin CCU-TX50, and performs system (including a camera) setting. It also performs command communica-tion with a camera, with RCP, as well as with the SW-1257 board on the front of the unit.This board is equipped with connectors for software upgrade, data input/output, and for Memory Stick.The signal generator circuit has functions to perform genlock synchronization with an external referencesignal and to control all video signal output phases.

MicrocomputerThe 32 bit microcomputer IC107 controls CCU-TX50 through serial IIC1, 2, 3 data communication witheach board.Its 25 MHz oscillation frequency is generated by the VCO X502.The 16 bit flash memory IC114 and IC115 store the control program, but it can be selected which ROMto store by S102. The control program is stored in IC114 when CCU-TX50 is shipped from the factory.The 1M bit SRAMs IC116 and IC119 are used as work memory. IC301 to IC305 handle input/output datafrom/to on-board switches, variable resistors, AC power supply unit, etc., including open/short-circuitalarm output of the Triax cable.

700 ProtocolThe AT-155 board communicates with the camera (DXC-D50) and the external control panel (RCP-D50/51) through the 700 protocol interface, using IC310 for communication with the camera, and IC308 withthe RCP. The 27 MHz oscillation frequency is generated by X301. Another VCO different from thegenlock circuit is used to prevent command communication failure due to occupation of external syncsignal. However, this board communicates with the SW-1257 board on the front of CCU-TX50 using theIIC3 interface.

Memory Stick ConnectorA Memory Stick, when inserted into CN103, allows software upgrade and camera/CCU data backup.IC123 controls the Memory Stick operation.

Signal Generator Circuit/Genlock CircuitThe AT-155 board generates the CCU-TX50 reference signal in X501. This VCO output is distributed toeach board.The external sync signal is input into IC507 (PLD) through IC501, IC515, and IC504. The PLD generatesburst gate signal, sync signal, and pedestal signal clamp signal using the external sync signal. The exter-nal subcarrier signal is also extracted from the external sync signal by IC502, and is sent to the EN-156board. IC503, IC505, IC523, and IC524 detect the difference between the internal signal and the externalsync signal to control the VCO of X501.


SW-1257 BoardThe SW-1257 board communicates with the AT-155 board using IIC data to control camera data andCCU data. IC1, IC2, and IC6 convert ON/OFF data of the switches on this board to IIC data. Analog dataof each variable resistor is converted by IC4 and IC9, and is then transmitted to the AT-155 board. TheLED ON/OFF data and the shutter/gain data transmitted form the AT-155 board pass through IC2 andIC7, and are then displayed on this board. It is possible for each variable resistor to select absolute-valueoperation or relative-value operation by using S17. Absolute-value operation is set for IRIS only, andrelative-value operation for the other variable resisters when CCU-TX50 is shipped from the factory.Further, S18 is used to change each self-illumination switch, white/black balance LEDs, as well as thebrightness of 7-segment display (for shutter, gain).In addition, main power, camera power, and cable open/short-circuit alarms are displayed with the signalssent from the AT-155 board.INCOM communication is available by connecting an INCOM headset to the XLR-5P connector. S101 isused to select PROD, ENG or PRIV, and S102 is used to select MIC ON, MIC OFF or PGM. In addition,S103 allows selection of microphone type (carbon, ECM or dynamic) in accordance with the microphoneof headset to be used.

VDA-62 boardThe VDA-62 board drives SDI, VBS, PIX, WFM, RGB signals to the BNC connector on the rear panel.This board also relays data between RCP and the AT-155 board.The WFM and PIX signals from the EN-156 board pass through the LPF and the amplifier, and are thenoutput to the connector CN4. The relay RY1 is always connected for signals to be output. The PIX signalbranches after FL2 and is sent to the PIX OUT connector of RCP. The Y/G, R-Y/R, and B-Y/B signalsfrom the EN-156 board are transferred to the BNC connector on the rear panel through this board.The data transmitted/received to/from RCP is converted to RCP communication format data by the RS-232C driver IC7. The RCP power (Q71, PH1) control circuit is not mounted. The IC4 digital audio outputis not supported as well.This board is able to select which output terminal (SDI or VBS for 3 channels) to use for signal outputbased on the setting of the DIP switch on the EN-156 board. The VBS signal passes through the LPFFL201, and is then input into the drive circuit composed of IC201 to IC205. The SDI signal is also inputinto the drive circuit comprising IC251, IC252, Q253, and Q254. However, only one circuit for selectedsignal is activated by the SDI/VBS selection signal that is input into Q202, and the selected signal isoutput to CN5 through the drive circuit. Same SDI/VBS selection circuits are provided for three channels.

IO-214 BoardThis board is used to merge the RF signal (between camera and CCU-TX50) and the power voltage to thecamera. The RF signal is supplied from CN2, and 180 VDC is supplied form W1. The RF signal passesthrough C1, and the 180 VDC passes through L4, L3, and L2, and these signals are merged and then sentto the camera.

SAFETY CHECK-OUT

After correcting the original service problem,perform the following safety checks beforereleasing the set to the customer :

Check the metal trim, “metallized” knobs, screws,and all other exposed metal parts for ACleakage. Check leakage as described below.

LEAKAGE TEST

The AC leakage from any exposed metal part toearth ground and from all exposed metal parts toany exposed metal part having a return tochassis, must not exceed 3.5 mA. Leakagecurrent can be measured by any one of threemethods.

1. A commercial leakage tester, such as theSimpson 229 or RCA WT-540A. Follow themanufacturers’ instructions to use theseinstruments.

2. A battery-operated AC milliammeter. TheData Precision 245 digital multimeter issuitable for this job.

3. Measuring the voltage drop across a resistorby means of a VOM or battery-operated ACvoltmeter. The “limit” indication is 5.25 V, soanalog meters must have an accurate low-voltage scale. The Simpson 250 and SanwaSH-63Trd are examples of a passive VOMthat is suitable. Nearly all battery operateddigital multimeters that have a 20 V AC rangeare suitable. (See Fig. A)
