1-2.Circuit Description
1-2-1. Camera System
AT-177 board
The AT-177 board is the microprocessor board that
controls the camera block.
DCP-44 board
The DCP-44 board consists of the block for A/D conversion
of the analog RGB signal from the PA-342/PA-342A/PA343/PA-343A/PA-344 board via the feedback clamp circuit,
the cam-era DSP block that performs the signal processing,
the dri-ver block that sends the analog signal that is D/A convert-ed to the outputs, and the I/F block to the AT-177 board.
1. Microprocessor peripherals
The CPU (IC209) uses SH2A (R5S7206), and the clock provides 32 MHz from an external source that is six multiplication in the CPU so that the clock runs on 192 MHz. The memory is composed of 64 MBit flash memory (IC302, IC303), 16
MBit SRAM (IC3056), and 1 MBit FRAM (IC308).
2. A/D input of the CPU
The A/D port equipped to the CPU is connected to the
following signal lines and monitored: CC position, ND
position, temperature, IRIS position of a camera lens,
ZOOM position, and mic volume level.
3. Internal communication
The serial communication includes intercommunication
with the BleConSh IC on the DCP-44 board, the writing
controls to the character generator IC, and
intercommunication with the disc.
The parallel communication is equipped with the 8-bit data
line, the total 11-bit address line (A0-A7, A14-A16),
control line clock, XRD, XWR, OE, DIR, CS, and
(QWERTY, ZXCV, TG).
In addition, the intercommunication is performed with
EEPROM on the DCP-44 board, the DAC and I/O port IC
for the video signal, and the I/O port IC on the FP-157
board with the I2C line that is installed directly to the CPU.
4. Memory stick circuit
The memory stick controller IC (IC610) is driven at 16
MHz, and the two-way communication and the clock
signal are directly connected from the connector (CN602)
to the memory stick connector of the MS-86 board via the
coaxial harness. This is compatible with the Memory Stick
PRO/DUO.
5. External communication
The 2 channel serial communication driver CXD9093R
(IC411) is equipped and performs external communication
with the remote control unit RM-B150/B750.
6. ROM jig connector (CN601)
The connector CN101 that can be connected to the jig for
writing the boot program (MS-86 board) is included.
1-4
After passing through the pre-filter (FL300 to FL302), the
analog RGB signal input from the PA-342/PA-342A/PA343/PA-343A/PA-344 board is converted to 74 MHz rate
14-bit digital RGB sign-al by the A/D converter (IC107 to
IC109), then input into the camera processor IC (IC600).
The camera signal processor IC (IC600) detects the
average value and the peak value of the camera video
signals that are required for the AUTO operations of the
camera such as AUTO black balance, AUTO white
balance, and AUTO iris control. The detected average
value and peak value are sent to the AT-microprocessor on
the AT-177 board. In addition to the above operations, the
25/30 PsF conversion function and the 1080 to 720
conversion function are realized by using the DDR
SDRAM (IC700 to 704).
After passing through white balance, white shading, and
flare correction, the camera main video signal performs the
Digital GAIN UP, then performs the Digital Noise
Reduction. Then, the matrix signal and the detail signal are
added to perform pedestal control, gamma correction, knee
correction, and white clip processing. After passing
through the selector circuit with which either the camera
main video signal or the color bar signal can be selected,
the selected signal is output from IC (IC600) to IC800.
The digital VBS signal and the digital Y signal for VF
supplied from the camera signal processor IC (IC800) are
converted into the analog VBS signal and analog VF signal
by the D/A converter* (IC1513, IC1524, IC1525). After
passing through the circuit with which either the camera
analog VBS signal or the VF Y can be selected, the
selected signal is output to the TEST OUT connector.
After passing through the circuit with which either the
GENLOCK IN connector input or the video signal can be
selected, the selected signal is output to the VF connector.
In addition, the sync separation circuit and the PLL circuit
to synchronize with the external input video of the GENLOCK IN connector are included.
The detected average value of the video signal detected in
the camera signal processor IC (IC600) and peak value are
loaded to the AT-microprocessor on the AT-177 board
through the 8-bit data bus.
PDW-700/V1 (E)
At the same time, various control signals are controlled by
the AT-177 board via I/O Expander (IC3, IC4, IC67).
All volumes are controlled electronically, and the level
adjustment is adjusted from the menu.
are generated by IC8 and are sent to the DR-617 board.
These pulses are generated from the 74 MHz clock in
synchronization with the HD VD signal input from the
DCP-44 board. In addition, the TG-260 board has an
interface circuit with the optical filter.
The main functions of IC800 are the down-conversion HD
to SD, the conversion 720 to 1080 for VF output, and the
VF DETAIL generation processing digital ECN
processing.
The camera main signal of the SD system is output to IC1000.
After performing the multiplex and parallel-serial
conversion on the character signal, audio signal, and the
ancillary signal in IC1000, the HD signal and SD signal
output from IC800 pass through IC (IC1112, IC1113) and
are output to SDI1 and SDI2 connectors as the HD-SDI
and SD-SDI signals. After another system performs scaling
in IC1000 through the SDRAM (IC1309), the HD signal
output from IC800 passes through the D/A converter
(IC1518) and the video signal is sent to the LCD display.
The HD signal output from IC600 is sent to the recording
system (DVP-45 board) through multiple character signals
in IC1000. After the signal from the RX-105 board on the
SDI input option and the SDI signal from the 50-pin I/F are
selected internally in IC1000, the signals are separated into
the video signal, audio signal, and the ancillary signal, then
sent to the recording system (DVP-45 board).
* :The main functions of IC800 are the down-conversion HD to SD, the
conversion 720 to 1080 for VF output, and the VF DETAIL generation
processing digital ECN processing. The camera main output of the SD
system is output to IC1000.
1-2-2. CCD Block
PA-342/PA-342A/PA-343/PA-343A/PA-344 board
The CCD drive pulses that are supplied from the TG-260
board are amplified so that these pulses can drive the CCD
imagers directly (IC2: H Driver). On the other hand, the
CCD output signals are amplified approximately two times
and input to IC10. The video signal is drawn by the co-related dual sampling inside IC10 and GAIN UP of 0 to 12
dB is performed by the internal GAIN AMP. In addition,
the differences in the CCD sensitivity are adjusted by
adjusting GAIN. In addition to the above operations, the
temperature that is detected by the temperature sensor
(IC4) is converted to the voltage data and is sent to the AT177 board via the DCP-44 board.
TG-260 board
The pulses that drive the CCD imagers and the pulses that
are used for sample-and-hold of the CCD output signals
DR-617 board
The CCD drive pulses input from the TG-260 board and
the sample-and-hold pulse are latched and output to the
PA-342/PA-342A/PA-343/PA-343A/PA-344 boards. In
addition, the DR-617 board has the V driver of CCD.
The CCD V sub voltage and CCD sensitivity adjustment
data are recorded in the EEPROM (IC20).

13. Backup lithium battery voltage measurement circuit
FP_CPU performs voltage measurement on the backup
lithium battery. When recharging is detected, the reducedvoltage information is send to ITRON (CPU).
(Measurement interval time: 60 s)
Current is prevented from running through FET-SW
(Q836) in order to prevent power from being lost during
measurement. Furthermore, reverse current above +3 V is
prevented with FET-SW (Q829), thus extending the life of
the lithium battery. The battery life is guaranteed for about
5 years.
14. FP_CPU independent operations
When the POWER-SW is set to power off, power is
supplied from the UNSW +12 V power circuit to display
the counter and other information on the monochrome
LCD. Power is supplied to each power regulator with
IC830 (hyposaturation regulator 8 V) and independent
operations can be performed. The operations can be turned
on or off from the menu.
15. REAR input control
The serial communication bus (SDA, SCL) for IC917
(Parallel bus to I2C_bus Controller) connected to the
FP_CPU bus sends control for the AXM-38 board through
the motherboard with IC202 (PCA-9555: I2C_I/O_PORT)
on the CNB-25 board and acquires the following
information: REAR_XLR automatic insertion detection

switching switch information.
16. REAR XLR automatic insertion detection circuit
control (DET-47 board and sensor holder)
Combine the DET-47 board on the sensor holder and
connect with the harness to the AXM-38 board.
The infrared light emitter uses one LED that connects to
the CH1 and CH2 receivers positioned in the middle of the
sensor holder on the left and right sides. When “Detection
ON” is set from the menu and the XLR connector is
inserted into the 3P-XLR connector, the infrared light is
blocked, the output from the receivers changes from L to
H, and insertion is detected. At this time, CH1 and CH2
operate automatically and the XLR input on the REAR
area is selected. (CH3 and CH4 are not switched
automatically. ) Detection interval time is 200 ms.
17. Color LCD monitor drive control and opening/rotation
detection circuit
The CN108 connector is connected to the power supply
and the RGB signal for video, the passes through CN802 to
connect directly into the LCD driver.
FP_CPU and LCD driver are connected with synchronous
serial communication. During POWER_ON, parameters
such as brightness and contrast can be set. This information is saved in the LCD (PD-118 board) nonvolatile
memory and the FP-157 board IC913 (nonvolatile memory).
Rotation is detected by the rotation sensor switch in DET45 after passing through CN802.
Opening and closing is detected from the hole terminal
(H801) on the FP-157 board and the field intensity from
the permanent magnet (neodymium: Ne-FeB).
18. Nonvolatile memory control
IC907 on the FP-157 board is nonvolatile memory that
supports the I2C bus.
This memory stores system information such as the A/D
and D/A error compensation values and color LCD
settings. During POWER-ON, this information is sent to
ITRON (CPU) and the color LCD device.
19. Monochrome LCD display circuit with backlight
FP_CPU and IC806 (UPD7225GB) are connected by a 500
KHz serial communication port. IC806 is an LCD
controller/driver that is programmable with software.
ND800 displays the BATTERY value, DISC capacity,
time, and counter value on the monochrome LCD at three
hour intervals.

1-2-5. Digital Audio System
DVP-45 board
1. Audio signal processing system
<Recording system>
The analog audio signal input from the AUDIO IN
connector is converted into a serial digital audio signal
(two channels) with the AUDIO A/D converter on the FP157 board. The digital audio signal enters CAVA (IC200)
of the DVP-45 board through the MB-1111 board.
The serial digital audio signal (four channels) input from
the AES/EBU INPUT connector undergoes level
conversion in the AXM-38 board and is input into CAVA
(IC200) of the DVP-45 board. After the signal is decoded
in CAVA (IC200), it is synchronized and converted to the
same sampling rated as the recorded video signal with the
sampling rate converter (IC700, IC703).
Digital audio signals (eight channels) that include input
HD-SDI signal (when the option is attached) are decoded
with the DCP-44 board. Then, the signals are converted
into serial digital audio signals and entered into CAVA
(IC200) of the DVP-45 board via the MB-1111 board.
CAVA (IC200) selects the above entered digital audio
signal and sends it as the recorded audio data to AUDIO
REC DSP (IC800).
The recording digital audio data is sent to AUDIO Low
Resolution DSP (IC900) through CAVA (IC200), Proxy
audio data is generated in compressed A-Low format, and
the data is sent to PIER G4 (IC1900).
The above recording digital audio data and recording
compressed Proxy audio data are written PIER_SDRAM
(IC1901 to IC1904).
The recording digital data from the i.LINK/network is sent
to PIER G4 (IC1900) via the PCI bus and written to the
PIER_SDRAM (IC1901 to IC1904).
While recording to a disc, the data in PIER_SDRAM
(IC1901 to IC1904) is sent to the DR-606 board via the
ATA interface.
<Playback system>
The audio data and the Proxy audio data are sent to PIER
G4 (IC1900) via the ATA interface and written to the
PIER_SDRAM (IC1901 to IC1904).
The playback digital audio data in PIER_SDRAM (IC1901
to IC1904) is sent from PIER G4 (IC1900) to AUDIO PB
DSP (IC801), After performing signal processing such as
limiter, playback level control, and mute processing, the
signal is input to CAVA (IC200).
The audio data and Proxy audio data in PIER_SDRAM
(IC1901 to IC1904) is provided to i.LINK/network via the
PCI bus as the MXF file data.
<Playback system>
The playback digital audio signal that underwent playback
signal processing in AUDIO PB DSP (IC801) is entered
into CAVA (IC200), then separated and converted into the
serial digital audio signals for analog output systems and
digital output systems.
The analog output system serial digital audio signal is sent
to the AUDIO D/A converter in the FP-157 board via the
MB-1111 board. After it is converted into an analog audio
signal, the signal is output to the AUDIO OUT connector,
headphone, and monitor speaker.
The digital output system serial digital audio signal is sent
to the DCP-44 board via the MB-1111 board. The signal is
combined with the video signal in the DCP-44 board and
output as the HD/SD-SDI audio signal.
2. Digital signal processing system
<Recording system>
The recording audio data from CAVA (IC200) undergoes
signal processing such as recording level control, muting
process, and MIX/SWAP in AUDIO REC DSP (IC800),
and then it is sent to PIER G4 (IC1900) as recording digital
audio data.
3. Sync signal system
The reference signal is always the 24.576 MHz clock
entered from the DCP-44 board, whether recording or
playing back.
This reference clock is divided and timing signal for 256
FS, 64 FS and FS audio processing is generated.

signals from the switch connected to each A/D terminal in
the FP_CPU (S1 to S4).
FP_CPU sends the switch position information to
ITORN_CPU of the SY-355 board, and then selects the
audio signal by receiving the audio mode information from
the ITORN_CPU.
The selected CH1 and CH2 system signals enter the
differential amp (IC5: balance-to-unbalance converter) and
pass through the head room level switching circuit and
balance-to-unbalance conversion amp for A/D. Then, the
signals are applied to the A/D converter IC (IC102: 24-bit).
The serial digital audio signal (2 channels) converted to
digital is entered to VAX (IC200) of the DVP-45 board via
the MB-1111 board
VAX (IC400) selects the entered digital audio signal and
sends it as the recorded audio data to AUDIO REC DSP
(IC800).
DSP for audio performs high-speed processing for
operations such as gain processing during manual
operations, AUTO processing, LIMITER processing, 67
Hz notch filter while using the front mic, LPF (15 KHz)
ON/OFF, internal SG, and audio level detection.
combined front and side volumes and sends the results to
DSP.
The D/A serial signal for playback passes through the
DVP-45 board and MB-1111 board and enters the digital
switch (IC461) of the FP-157 board. In the monitor CHSW, CH1&2 or CH3&4 is selected and applied to the 24bit D/A converter (IC453).
The D/A converter output passes through the differential
LPF, ATT balance-to-unbalance conversion amp (IC514),
and MB-1111 board. It is applied to the final amp (IC200,
IC201) of the CNB-25 board and output from the 5-pin
XLR connector (AXM-38 board).
The audio signal for the monitor passes from IC520/620
output through the monaural, mix, and stereo switching
switch (IC703, IC704). Then, the signal is applied to the
operation amp (NJM2172) with electronic volume.
The rear earphone can be switched between stereo and
mono from the menu.
The monitor speaker output level can be lowered from the
volume. Select one of the following for the ATT value: 0,
_3 dB, _6 dB, or _9 dB.
On the other hand, the front volume and side volume are
connected to the A/D terminal in the CPU and the volume
voltage is converted into digital with the internal 10-bit A/
D. After being converted into a multiplication value for
DSP, the signal is sent to ITORN_CPU.

1-2-8. Optical Drive System
Recording System
Recording data sent from the DVP-45 board through the
ATA bus (Ultra ATA33) is sent to the Blu-ray Disc
Controller (BDC) IC300 on the DR-606 board.
The BDC performs signal processing to conform to
recording format, such as ATA interface, ECC coding and
17PP (Parity Preserve/Prohibit RMTR) modulation.
The recording data is converted to multi-pulse in the BDC,
and the multi-pulse data is sent through the flexible card
wire to the optical block to be written into the disc.
Playback System
• Data Playback System
The RF signal played back from the disc is sent from the
optical block to the Front End Processor (FEP) IC200 on
the DR-606 board where equalizing and asymmetry
correction are performed after the RF signal passes
through the AGC. After A/D conversion by the read
clock played back in the PLL, the signal is sent to the
BDC IC300.
In the BDC, the signal passes through the adaptive
digital filter, and Viterbi demodulation, 17PP demodulation, and ECC decoding are applied to the signal. Then
the signal is sent through the ATA bus to the DVP-45
board as played back data.
The tilt actuator is controlled for its angle against the
disc to be optimum based on the tilt adjustment result for
the jitter of the playback signal to be minimum and the
output of the angular velocity sensor.
The SA actuator position is controlled for the spherical
aberration to be optimum at the start-up adjustment when
the disc is inserted. The SA actuator for the double layer
disc is controlled to the optimum position every time to
jump the layer.
• Seek Motor
The seek motor controls the position of the optical block
so that the track to be recorded or played back is kept
within the object lens driving range.
• ND Filter
The transmission factor of the ND filter is selectable to
reduce the laser noise that occurs when the read power
light is emitted for the single layer disc.
• Spindle Motor
The FG generated by the spindle motor is amplified and
shaped on the SE-857 board, and is then input into the
SV DSP IC400 on the DR-606 board.
The SV DSP compares the FG frequency with the target
frequency, and then controls the spindle motor via the
driver IC500.
• Address restoration system
The address data restored from the disc is sent from the
optical block to the FEP (IC200) on the DR-606 board.
The analog address data passes through the AGC and
BPF and is converted to digital data in the FEP. The
digital data is then sent to the BDC (IC300) for address
decoding.
The PLL in the FEP generates a wobble clock (WCK).
Servo System
• Tri-Axis Actuator and SA Actuator
The object lens of the optical block is controlled for
focus direction, track direction, and tilt angle by the tri
axis actuator.
The light reflected from the disc is converted to the
electrical signal by the optical block. The electrical
signal is input to the FEP IC200, and the focus error
signal and the track error signal are detected. The SV
DSP IC400 outputs the control data based on the errors
to the driver IC501 and controls the focus actuator and
the track actuator through the driver.
System Control
The SY CPU IC600 on the DR-606 board performs system
control. It controls ATA interface, Data Manager, RFrelated ICs, servo ICs, and loader. It also carries out
interlocking control, maintenance and error log
management of each device including the optical block.
Firmware programs of the SY CPU and DSP as well as
sources of each PLD are stored in the flash memory IC602,
and the CPU loads them to each device when the power is
turned on.
The BDC IC300 and SV DSP IC400 are controlled by the
parallel CPU bus, while RF-related ICs are controlled by
the serial port through SYS PE IC700.
Adjustment values and hours meter data are stored in the
EEPROM IC4 on the SE-857 board.

the input power is set to below 18 V.
CNB-25 board
The board checks the input voltage +12 V, and controls
distribution of the input power to each circuit board.
• Power ON/OFF Control
The ON/OFF control is performed in IC1 and IC5. The
IC1 input signals include L PWR SW ON signal, H
POWERW HOLD signal, EXTDC detection signal,
battery detection, excess voltage detection, and low
voltage detection. During normal operation, when L
PWR SW ON signal is turned to “L”, Q4, 5, 6, and 7 or
Q11, 12, 15, and 16 are turned on, and the battery or
EXT DC IN +12 V is supplied to respective circuit. The
H POWERW HOLD signal is sent from the FP-157
board after the main power of this unit is turned on.
Therefore, the power is kept on even if the L PWR SW
ON (L) signal is set to OFF (H). In order to turn off the
main power of this unit, the L PWR SW must be turned
off (H) and the H POWERW HOLD signal must be
opened and set to “L”. When the FP-157 board detects
that the POWER switch is turned OFF, it sets the
POWERW HOLD signal to “L” to turn off the power
after a disc operation is completed if the equipment is in
the midst of operating a disc.
• Battery/EXT DC selector
The EXT DC voltage is detected and either battery or
EXT DC is selected with priority given to the EXT DC.
The IC5 performs the control and Q4, Q5, Q6, and Q7
are turned on when a battery is selected and Q11, Q12,
Q15, and Q16 are turned on when the EXT DC is
selected.
In this IC5, a step-up circuit (Vcc +8.5 V) that drives the
N-CH MOS FET gate is employed.
• Excess current detection
The output circuit of the UNREG +12 V has excess
current detection resistors R70, R71 and R72. A voltage
drop at the resistors is detected by the IC5.
When the voltage drop at the resistors exceeds 200 mV,
the +12 V output is turned off.(SHUT DOWN)
Another SHUT DOWN signal is the H SHUT DOWN
signal that is supplied from the RE-246 board. If any one
of the DC-DC converter outputs is shorted, the output 12
V enters the SHUT DOWN state except UN SW +12 V.
(SHUT DOWN)
Since this function is a latch operation, the main power
of the unit needs to be turned off once and back on after
the cause of the excess current is removed.
• Protection against input power connection of reverse
polarity
If the input power is connected in reverse polarity, FET
(Q2) is turned off so that the GND lines of the control
system circuits are disconnected. Thus the control
circuits are protected and supply of +12 V power to the
respective circuits is stopped.
• FAN voltage control
The Q13 and Q14 are controlled by the FAN CONT
signal from the AT-177 board and the PWM wave is
converted to the DC voltage according to the DUTY.
The voltage controls the FAN and reduces the temperature increase.
• Audio Circuit
This is the output circuit for the AUDIO OUT (rear
connector). The signal is output by selecting the CH1/2
or CH3/4 in the MONITOR.
• Protection from Excess Input Voltage
VOLTAGE DETECT (IC18) monitors the input +12 V.
If the voltage exceeds approximately +18 V, the output
of the IC18-1 is set to “H”. This is input to IC1 to start
the protection from the excess voltage and turn on the
+12 V output. (SHUT DOWN)
Since this function is a latch operation, the main power
of the unit needs to be turned off once and back on after
PDW-700/V1 (E)
• ± 4.8 regulator circuit
This is the voltage regulator for AUDIO using on the
AXM-38 board.

1-2-10. LCD System
PD-118 board
The PD-118 board consists of the color LCD panel drive
circuit and the power supply circuit for LCD backlight.
IC1 is the color LCD panel drive IC that contains of the
built-in video signal RGB driver, the timing generator, and
the VCO.
IC1 also contains the serial interface circuit and electronic
potentiometers that are used to establish the various setups
in accordance with the commands from the microprocessor
(IC921) of the FP-157 board.
The RGB video signals that are input to IC1 pin-37
through pin-39 receive contrast adjustment and brightness
adjustment. Then, they pass through the output signal
polarity inversion circuit and are output from IC1 pin-20
through pin-22.
The factory adjustment data is stored in the IC3 EEPROM.
The respective timing signals for driving the LCD panel
are generated from the sync signals that are input to IC1
pin-41 and pin-42.
The operations such as turning off the backlight and
inverting the video signal left to right or up to down are
performed in accordance with the control signals supplied
from the microprocessor (IC921) of the FP-157 board.
LOW so that the camera microprocessor checks capacity
and types of the memory stick inserted.
VCC is supplied to a memory stick only when a memory
stick is inserted or only when accessing a file on a memory
stick. When VCC is supplied, the INS_LED and
ACTIVE_LED (D1) is turned ON.
Access to the memory stick data is processed in the
following order: VCC IN → SCLK ON → BS Pulse →
DATA IN/OUT → SCLK OFF → . . → SCLK ON →
BS ON → DATA IN/OUT → SCLK OFF → . . → VCC
OFF.
