1-3. Circuit Description
1. CMOS Block System
BI-202/203/204 Board
The BI-202, BI-203 and BI-204 boards are the rigid
flexible boards connecting the CMOS image sensors (IC1)
to the DPR-289A board.
the following AUTO operations of the camera are detected.
The detected signals are sent to the CAMERA MICON
(camera u-processor: IC314).
. Auto white balance
. Auto black balance
. Auto focus
. Auto iris
. Auto knee
The CMOS image sensor receives the three primary colors
of R, G and B that are separated from the incoming light
by the prism. The CMOS image sensor converts the
incoming primary color to electric signal. The built-in 12bit column A/D converters then convert the R, G and B
analog video signals to the digital video signals respectively.
The electronic shutter, analog gain amplifier and black
level clamp functions are also provided in the above
boards.
The BI-202 board is for the R-channel signal, the BI -203
board is for the G-channel signal and the BI -204 board is
for the B-channel signal.
The CMOS image sensor receives the sync signal and the
serial communication signal from the DPR-289A board.
The 12-bit digital video signals that are supplied from the
CMOS image sensors pass through the EMI filters (FL1 to
FL4) and are input to the DPR-289A board.
Various decoupling capacitors and the damping resistors
are also mounted in the above boards.
IC3 of the BI-203 board is a temperature sensor that sends
the temperature data to the CAMERA MICON (camera u-
processor: IC314) on the DPR-289A board via I2C bus.
2. Camera Block System
DPR-289A Board
The DPR-289A board consists of the Camera Signal
Processor IC (IC100) and the CAMERA MICON (camera
u-processor: IC314) whereas the Camera Signal Processor
IC (IC100) performs various processing on the digital
video signal supplied from the CMOS image sensor, and
the CAMERA MICON (IC314) performs control of IC100
and other various controls such as control of the CMOS
image sensor and of lens. The output digital video (Y/C)
signal is sent to the next circuit the video (baseband video)
signal processing circuit.
The 12-bit digital video (RGB) signals supplied from the
CMOS block (BI-202, BI-203 and BI-204 boards) first
enter the camera signal processor IC (IC100). In the
camera signal processor IC (IC100), average value, peak
value of the RGB digital video signals that are required for
The digital video signal from the CMOS image sensor
enters first the selector circuit selecting either the digital
video signal from the CMOS image sensor or the internal
TEST signal. The output video signal from the selector
enters the compensation circuits consisting of the CMOS
imager-related compensation circuit and the lens-related
compensation circuit. The video signal then receives the
white balance processing, and the matrix signal and the
detail signal are added to the video signal. The video signal
then receives the pedestal control, knee compensation,
gamma correction and white/black clip processing. The
video signal finally enters the baseband processing IC
(IC400).
The pixel number conversion processing from 1920/1080
to 1440/1080 or 1280/720 is also performed inside IC100.
The CAMERA MICON (camera u-processor: IC314)
performs the overall control over the entire camera system
and is controlled by the camera system controller
(IC1600).
Peripheral ICs of the CAMERA MICON (camera u-
processor: IC314) are FLAH ROM (IC312) and SRAM
(IC313). The CAMERA MICON (camera μ–processor:
IC314) confirms the iris control and lens setup when the
analog I/F lens is installed.
3. Video Signal System
DPR-289A Board
The digital video (Y/C) signal output from the camera
signal processor IC (IC100) enters the baseband processing
IC (IC400).
The baseband processing IC (IC400) performs the overall
baseband processing of video and audio signals with a
single chip IC containing the various scaler functions
(supporting the multiple format outputs), various OSD
functions, PLL function (54 MHz → 74 MHz) and CPU.
The baseband processing IC (IC400) provides the following outputs:
. HD/SD-SDI (digital): To TX-129 board
. HD/SD Component (analog): To JK-81 board
. Composite (analog): To JK-84 board
. S-Video (analog): To JK-84 board
. LCD signal (digital): To IF-1072 board
PMW-EX3

The input/output signals of the baseband processing IC
(IC400) are the following signals:
. MPEG encoder/decoder I/F signal (digital): To IC901
. Audio I/F signal (digital): To IC804
PAM memory (IC700, IC701).
Peripheral circuits of the built-in CPU are FLASH ROM
(IC603) and SDRAM (IC607).
The baseband processing IC (IC400) is controlled by the
system controller (IC1600). The LCD driver IC, SDI Copro, the audio system and the power save control of the
output systems are controlled by the built-in CPU inside
IC400.
4. Media Recording and Playback
DPR-289A board
Output from the baseband processing IC (IC400) is input
into the MPEG encoder/decoder (IC901).
The MPEG encoder/decoder (IC901) is the single-chip
MPEG Codec IC that encodes and decodes both the highquality HD video signal and audio signal in real-time. It
has various interfaces with signals such as MPEG video,
video input/output, MPEG audio, audio input/output, bit
stream input/output, and interface with the host.
IC901 output is then input into LSI (IC900) for AVIT
signal processing.
LSI (IC900) for AVIT signal processing contains the builtin CPU and has interfaces for DDR2 SDRAM memory
(IC1000, IC1001), PCI bus, PCI-Express bus, I/O for
IC901, and serial communication with system controller
(IC1600).
IC900 is also connected to the NOR-type Flash ROM
(IC1100) to read the CPU program in the IC900 during
initial startup.
LSI (IC900) for AVIT signal processing is controlled by
the system controller (IC1600), in the same way as other
main devices, and provides the following types of functions: video/audio stream control, access to the SxS
memory card, mass storage operations when connected to
USB and HDV device controls when connected to i-LINK.
Explanation of peripheral devices
<SxS memory card slot>
Two memory card slot boards (EC-63) are connected to the
dual channel PCI-Express signals coming from IC900
through a 0.5 mm pitch, 30-pin fine coaxial cables connected to CN1300 and CN1301.
Furthermore, dual channel USB host signals output from
USB host controller (IC1302) are connect to the EC-63
board through fine coaxial cables just as with the PCIExpress signals.
IC1302 is controlled by PCI bus from IC900.
<USB device controller>
USB device signal output from USB device controller
(IC1101) is connected to output board (JK-81) through the
both-sided flexible board (HN-347) from CN1805 connector, and then it is connected to USB Mini-B connector
(CN6) on the JK-81 board.
IC1101 is controlled by the dedicated bus from IC900.
If there is no USB connection, the power supply for
IC1101 drops off.
<i-Link controller >
The i-Link signal output from the i-Link controller
(IC1200) passes through the both-sided flexible board
(HN-337) from the CN1803 connector. Then, the signal is
sent from CN3 on HN-337 to the i-Link connector board
(CN-3050) through the shielded wire, and connected to the
4 Pin i-Link connector (CN3) on the CN-3050 board.
IC1200 is controlled by the PCI bus from IC900.

. Audio signal from the built-in microphone on the MA-
164 board is input to the balanced input amplifier IC101
and IC201 of this board. Output of the balanced amplifier is connected to the analog switch (IC105, IC205) for
switching between [INT/EXT].
. The DC-DC converter (IC1, Q1) for microphone power

be supplied, the EXT MIC +48 V is supplied by the
switch (Q301, Q302, Q321 and Q322).
. The audio input signals from MIC and LINE are input to
a common circuit that receives both of the MIC input
level (_8 dBu to _65 dBu) and the LINE input level (+4
dBu). The input attenuator is inserted in the circuit
switch (Q103 to Q105, Q203 to Q205) as required. This
audio input signal is received by the balanced input
amplifier (IC102, IC202) that performs amplification of
0/+12 dB and switching (Q110, Q111, Q210, Q211) in
accordance with the level that is set by INPUT TRIM.
After that, the audio signal is connected to the [INT/
EXT] switch (IC105, IC205).
. The [INT/EXT] switch (IC105, IC205) performs not only
the INT/EXT switching but also performs the input
channel mode selection [CH1/ (CH1/CH2)].

the ADC.
The digital signal receives the audio level control
processing from the DSP. After the audio signal receives
the [Wind Filter] (on/off) processing, the digital signal is
output for audio recording.
Playback output (including EE) is the digital signal that
is connected to Audio Codec where it is converted to the

playback output signal from the Display Block.
The playback system selects CH1/CH2 or CH3/CH4,
connects EE, and connects TEST TONE from the
Display Block depending on the data.
Furthermore, C-PLD divides the clock signal that is
supplied from the Display Block to Audio Codec.
. Serial control
The I2C control from Display Block (T-one) selects
either IC800 or IC801 for the target with I2C MPX and
sets the register of IC800 or IC801.
HN-337 flexible board
It relays the audio signal from the DPR-289A board to the
ASW-66 board.
ASW-66 board (Audio block)

is buffered by IC103 and is output to the A/V connector
after passing through the audio MUTE control.
. Analog output from DAC on the DPR-289A board re-
enters into the AUX input of the DPR-289A board
AUDIO CODEC after passing through the monitor
selector/mixer (IC100, IC101, IC102), and becomes the
monitor signal.
. Serial control

the system controller (IC1600).
It has the peripheral interface functions of SDRAM, USB,
SCI, and I2C. It operates on a 27 MHz clock (X1600).
FLASH ROM (IC1603), SDRAM (IC1604), and EEPROM (IC1703) are mounted as the peripheral ICs.
It performs the system control through serial communication with IC314 of the camera block system, IC400 of the
video signal system, and IC900 of the media recording/
playback system.
1-8
PMW-EX3
Main functions of the system controller and
peripherals
(1) Reading operation switch information
Reading the switch information and the LED control
are performed by I2C bus communication with each
sub-microprocessor.
. Handle switch: IC100 on the KSW-54 board
. Inside panel front switch: IC601 on the SWC-48
board
. Rear panel switch: IC106 on the ASW-66 board
. Power supply switch: IC1001 on the RE-261 board
(2) Watch IC (RTC) control
The watch IC (IC50) is built onto the AU-318 board.
The watch IC (IC50) is backed up by a lithium coin
battery, and the current time is read or set via IC601 on the
SWC-48 board.
(3) Infrared remote control demodulation
The RM-214 board has an IC (IC1) for infrared remote
control signal demodulation, and it receives the command
codes via IC100 on the KSW-54 board.
(4) Info-Battery communication
The Info-Battery of SM bus specifications is supported.
The serial terminal of the battery connector is connected to
IC1001 on the RE-261 board. This IC1001 reads the
battery authentication, battery type, remaining power, and
other information and send them to the system controller
via I2C bus communication.
(5) Power supply voltage detection
The power supply voltage at the DC IN connector is
measured by the A/D port on IC1001 on the RE-261 board,
and it is posted to the system controller as the input voltage
value.
(6) Power system control
IC1001 on the RE-261 board checks that the power switch
on the PMW-EX1 is turned ON, and turns on the system
controller of IC1600. After that, it controls the power for
each circuit block according to the system controller.
The system controller controls the respective power supply
systems in the RE-260 and RE-261 boards according to the
operation mode of the device, via the power supply uprocessor on the RE-261 board.
By turning off the power systems to unnecessary circuits
blocks, power can be saved.
(7) 700P communication
The serial communication driver (IC803) is mounted on
the TX-129 board.
Serial communication with the remote control unit connected to the REMOTE connector is performed.
7. SDI/GENLOCK/TC IN/TC OUT
TX-129 board
(1) SDI output
This board receives the parallel video signal with FPGA
(IC100) and IC500 and outputs the SDI signal.
Furthermore, it performs audio or timecode embedding.
The video and audio signals are supplied from CN400 on
the DPR-289A board to CN100 on the TX-129 board with
a 0.4 mm pitch, 40-pin fine coaxial cable.
The power voltages are supplied from CN401 on the DPR289A board to CN700 on the TX-129 board with a 15-pin
harness.
Output SDI signals are supplied to CN500.
Output SDI signals are then supplied from CN500 to the
coaxial connector via the mini coaxial connector and mini
coaxial cable.
The PLL circuit is used to reduce jitter of the HD-SDI
clock signal.
The FPGA (IC100) is controlled by IC400 on the DPR289A board through 4-line serial communication.
The FPGA program is stored in the IC203 ROM, and
JTAG can be used to overwrite the data from IC1600 on
the DPR-289A board.
When not using SDI, the power to cable driver inside
IC500 is turned off.
(2) GENLOCK
In IC902, sync signal separation is performed for GNELOCK. The separated sync signal enters IC400 on the
DPR-289A board where phase is compared by the internal
counter of IC400 and by IC521 to control the VCXO
(X500).
(3) TC IN/TC OUT
IC900, IC901, and IC907 reshape the waveform of the
time code connected to the TC IN connector and input it to
IC100.
IC903 is the external output circuit for the time code OUT
signal, which outputs the signal to the TC OUT connector.
They communicate with the FPGA (IC100) through the 4line serial interface on the DPR-289A board.
PMW-EX3

8. Power supply system
RE-260/261 board
This board is comprised of the power supply circuit and
the POWER SUPPLY MICON (power supply u-processor:
IC1001 on the RE-261 board).
However, part of the low-voltage power supply is mounted
on the DPR-289A board.
(1) Input power supply (UNREG) system operations
When the UNREG power is input, the EVER power state
is established.
In this state, the ON/OFF state of the Power switch can be
recognized.
If the POWER SUPPLY MICON (power supply uprocessor: IC1001) recognizes that Power switch is ON,
the power is turned on for the system control system and
the POWER SUPPLY MICON (power supply u-processor:
IC1001) controls the power supply for each block according to the system controller (DPR-289A board: IC1600).
The normal value for the input power supply (UNREG) is
in the range of about +10.5 V to +18 V.
. Battery/EXT-DC select
Input power comes in two systems: Battery and EXTDC. This switch monitors the input voltage for each
input and automatically switches the circuit settings with
priority given to EXT-DC.
. Input overvoltage protection
If the voltage is too high in the UNREG power supply,
the overvoltage protection circuit starts operating around
the set value of +17.9 V, and the camera shuts down.
When the input power supply voltage to this circuit
becomes less than +17.9 V, the power supply immediately switches on with automatic recovery.
. Input low-voltage protection
If the voltage is too low in the UNREG power supply,
the low-voltage protection circuit starts operating around
the set value of +10.5 V according to the control by the
POWER SUPPLY MICON (power supply u-processor:
IC1001), and the camera shuts down. When the input
power supply voltage becomes higher than +10.5 V, the
power supply immediately switches on with automatic
recovery according to the control by the POWER
SUPPLY MICON (power supply u-processor: IC1001).
. Overcurrent detection
The overcurrent detection circuit is comprised of IC308
on the RE-260 board. The setting value is approximately
4.3 (A). Even after clearing IC308 after overcurrent
detection, automatic recovery is not performed and the
power must be turned on again.
1-10
. Power supply reverse connection protection
If the input power has reverse voltage, Q301 on the RE260 board is immediately turned off and UNREG power
is stopped on the GND side, and the protection function
works.
(2) DC/DC converter function
The power supply output is divided into 25 systems, which
are separated into four blocks as seen below.
. CMOS/camera block system, 7 systems
(+4.6 V, +3.1 V, UNREG, etc.)
. Audio/video signal system, 7 systems
(+13.5 V, _4.6 V, +4.6 V, etc.)
. System controller system, 5 systems
(+4.6 V, +3.1 V, +2.5 V, etc.)
. Media recording/playback system, 6 systems
(+3.1 V, +2.5 V, +1.8 V, etc.)
The sequence control (powering up and powering down)
for the power supply system is controlled by the POWER SUPPLY MICON (power supply u-processor:
IC1001) for the respective power supply blocks of each
block.
By turning off the power for each block according to the
operation mode (camera mode or media mode), the
optimal power consumption for each operation is
achieved.
. Short-circuit protection for each power supply system
The circuit settings monitor each output voltage or
current for each power supply system and operate the
protection circuits per block.
Even after the protection circuit is cleared, automatic
recovery is not performed and the power must be turned
on again.
Even after short-circuit is cleared, the protection circuit
does not recover automatically and the power must be
turned on again.
Battery information functions
. Battery authentication function
The authentication function checks whether the battery is
of the specified type. This helps prevent one cause of
major accidents when using batteries as a power supply.
If the attached batter is not the specified type of batter,
the camera immediately turns off.
. Battery Info function
In an intelligent (specified) battery, the battery can
monitor information, such as how many times the battery
has been recycled or the internal temperature for the
battery. This helps provide detailed information about
the battery, including whether the battery is damaged or
how long the life is, in order to provide optimal operations.

number.
1-7-4. Memory Backup Battery
For replacing the battery, refer to “Backup Battery” of the
“Appendixes” in the Operating Instructions.
When the backup battery is replaced, the date and time in
the internal clock need to be set. Refer to “Setting the
Clock” of the “Preparations” in the Operating Instructions.
1-7-5. Unleaded Solder
Boards requiring use of unleaded solder are printed with a
lead free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come
printed with the lead free mark due to their particular size.)
: LEAD FREE MARK
1-14
m
. Be sure to use the unleaded solder for the printed circuit
board printed with the lead free mark.
. The unleaded solder melts at a temperature about 40 dC
higher than the ordinary solder, therefore, it is recommended to use the soldering iron having a temperature
regulator.
. The ordinary soldering iron can be used but the iron tip
has to be applied to the solder joint for a slightly longer
time. The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful.

1-9. Replacing the Flexible Card Wires
n
The flat cables, flexible card wires and boards are used to
connect between the following boards. Life of flexible card
wire will be significantly shortened if it is folded. Be very
careful not to fold the flat cables, flexible card wires and
boards.
The two types of different shape connectors are used in
this unit.
Because the direction of the flat cables, flexible card wires
and boards are different depending on the shape of the
connector, be careful when connecting the flat cables,
flexible card wires and boards.
Disconnecting
1. Turn off the power.
2. Slide or lift up the portion A in the direction of the
arrow to unlock and pull out the flexible card wire.
