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-311 board.
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 12-bit 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-311 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-311 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
μ-processor: IC500) on the DPR-311 board via I2C bus.
2. Camera Block System
DPR-311 Board
The DPR-311 board consists of the Camera Signal Processor IC (IC200) and the CAMERA MICON (camera μ-processor:
IC500) whereas the Camera Signal Processor IC (IC200) performs various processing on the digital video signal supplied
from the CMOS image sensor, and the CAMERA MICON (IC500) performs control of IC200 and other various controls
such as control of the CMOS image sensor and of lens. And 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 (IC200). In the camera signal processor IC (IC200), average value, peak value of the RGB
digital video signals that are required for the following AUTO operations of the camera are detected.
The detected signals are sent to the CAMERA MICON (camera μ-processor: IC500).
.Auto white balance
.Auto black balance
.Auto focus
.Auto iris
.Auto knee
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 compensa-
tion 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 (IC600).
The pixel number conversion processing from 1920/1080 to 1440/1080 or 1280/720 is also performed inside IC200.

1-5 (E)
PMW-EX1R
The CAMERA MICON (camera μ-processor: IC500) performs the overall control over the entire camera system and is con-
trolled by the camera system controller (IC2900).
Peripheral ICs of the CAMERA MICON (camera μ-processor: IC500) are FLAH ROM (IC413) and SDRAM (IC414).
3. Video Signal System
DPR-311 Board
The digital video (Y/C) signal output from the camera signal processor IC (IC200) enters the baseband processing IC
(IC600).
The baseband processing IC (IC600) 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 (IC600) provides the following outputs:
.HD/SD Component (digital): To TX-131 board
.HD/SD Component (analog): To TX-131 board
.Composite (analog): To TX-131 board
.LCD signal (digital): To LCD module
.EVF signal (analog): To DR-644 board
The input/output signals of the baseband processing IC (IC600) are the following signals:
.MPEG encoder/decoder I/F signal (digital): To IC1500
.Audio I/F signal (digital): To IC1300
Peripheral circuits of the baseband processing IC (IC600) are the master clock 54 MHz VCXO (X800) control circuit
(IC803, IC804, IC806, IC807, IC808) and the Mobile DDR SDRAM memory (IC1100, IC1101).
Peripheral circuits of the built-in CPU are FLASH ROM (IC1003) and SDRAM (IC1000).
The baseband processing IC (IC600) is controlled by the system controller (IC2900). The LCD driver IC, the EVF driver
IC, SDI Co-pro, the audio system and the power save control of the output systems are controlled by the built-in CPU
inside IC600.
4. Media Recording and Playback
DPR-311 Board
Output from the baseband processing IC (IC600) is input into the MPEG encoder/decoder (IC1500).
The MPEG encoder/decoder (IC1500) is the single-chip MPEG Codec IC that encodes and decodes both the high-quality
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.
IC1500 output is then input into LSI (IC1600) for AVIT signal processing.
LSI (IC1600) for AVIT signal processing contains the built-in CPU and has interfaces for DDR2 SDRAM memory (IC1800,
IC1801), PCI bus, PCI-Express bus, I/O for IC1500, and serial communication with system controller (IC2900).
IC1600 is also connected to the NOR-type Flash ROM (IC1901) to read the CPU program in the IC1600 during initial startup.
LSI (IC1600) for AVIT signal processing is controlled by the system controller (IC2900), 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-68) are connected to the dual channel PCI-Express signals coming from IC1600 through
a 0.4 mm pitch, 30-pin fine coaxial cables connected to CN2400 and CN2401.
Furthermore, dual channel USB host signals output from USB host controller (IC2300) are connect to the EC-68 board
through fine coaxial cables just as with the PCI-Express signals.
IC2300 is controlled by PCI bus from IC1600.

1-6 (E) PMW-EX1R
<USB device controller>
USB device signal output from USB device controller (IC2000) is connected to output board (DAP-41) through the both-
sided flexible board (HN-356) from CN3302 connector, and then it is connected to USB Mini-B connector (CN106) on the
DAP-41 board.
IC2000 is controlled by the dedicated bus from IC1600.
If there is no USB connection, the power supply for IC2000 drops off.
<i-Link controller>
The i-Link signal output from the i-Link controller (IC2200) is connected to the 4-pin i-Link connector (CN3) on the
CN-3273 board passing through the both-sided flexible board (CN-3273) from the CN3400 connector.
IC2200 is controlled by the PCI bus from IC1600.

This board performs the read and tally controls for the switch on the handle. The audio signal block relays the audio signal
between the MA-183 board and AXM-42 board.
HN-360/HN-361 Flexible board
This board relays the audio signal between the KSW-55 board and the AU-326 board.
AU-326 Board (Audio block)
This board controls the analog audio input signal processing, as well as microphone +48 V power supply and serial signal.
.Audio signal from the built-in microphone on the MA-183 board is input to the balanced input amplifier IC200 and IC201
of this board. Output of the balanced amplifier is connected to the analog switch (IC208, IC209) for switching between
[INT/EXT].
.The DC-DC converter (IC100, Q100) for microphone power +48 V is built-in, and when EXT MIC +48 V is going to be
supplied, the EXT MIC +48 V is supplied by the switch (Q200, Q201, Q202 and Q203).
.The audio input signals from MIC and LINE are input to a common circuit that receives both of the MIC input level (_20
dBu to _65 dBu) and the LINE input level (+4 dBu). The input attenuator is inserted in the circuit switch (Q212, Q213,
Q214, Q215 and Q216 to Q219) as required. This audio input signal is received by the balanced input amplifier (IC202,
IC203) that performs amplification of 0/+12 dB and switching (Q224, Q225, Q226, Q227) in accordance with the level
that is set by INPUT TRIM. After that, the audio signal is connected to the [INT/EXT] switch (IC208, IC209).
.The [INT/EXT] switch (IC208, IC209) performs not only the INT/EXT switching but also performs the input channel
mode selection [CH1/ (CH1/CH2)].
.SEL (IC204, IC205)/AMP (IC206, IC207) are a signal selector and buffer amplifier to perform AGC link.
DAP-41 Board (Audio block)
The DAP-41 board is comprised of two pieces of the Audio Codec IC and the IC202, IC203.
(RTC is also built on this board, but the explanation has been omitted here.)

PMW-EX1R
.Audio Codec (IC202, IC203)
The analog audio signal from the AU-326 board is connected to IC202 and IC203 that are the Audio Codec (PGA, ADC,
DSP, Digital IF, headphones amplifier, speaker amplifier are built on one chip and the parameters are set with I2C).
The analog signal after level adjustment by the Input TRIM (PGA) is converted to the digital signal with the ADC.
The digital signal receives the [Wind Filter] (on/off) processing of the Audio Level control, AGC Limiter and Internal
mic from the DSP. After the audio signal receives these 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 analog
signal with DAC and output to the ASW-68 board.
Furthermore, the audio signal that is processed for audio monitoring in the ASW-68 board is connected to the headphones
amplifier and speaker amplifier through the monitor level control from the IN2LP input and IN2RP input of IC202.
From the DPR-311 board, BEEP (IC600) is level-controlled internally by IN2LN (IC202), and output to the speaker HP.
.FPGA (IC1300) on the DPR-311 Board
The digital signal output signal is supplied to the Display Block (Base band) from the Audio Codec. FPGA (IC1300) also
receives 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, FPGA divides the clock signal that is supplied from the Display Block to Audio Codec on the DAP-41 board.

It has the peripheral interface functions of SDRAM, USB, SCI, and I2C. It operates on a 27 MHz clock
(X2900). FLASH ROM (IC2908), SDRAM (IC2909), and EEPROM (IC3205) are mounted as the periph-
eral ICs.
It performs the system control through serial communication with IC500 of the camera block system,
IC600 of the video signal system, and IC1600 of the media recording/playback system.

1-9 (E)
PMW-EX1R
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-55 board
.Inside panel switch: IC200 on the SWC-50 board
.Rear panel switch: IC301 on the ASW-68 board
.Power supply switch: IC1001 on the RE-273 board
(2) Watch IC (RTC) control
The watch IC (IC100) is built onto the DAP-41 board.
The watch IC (IC100) is backed up by a lithium coin battery, and the current time is read or set via IC200
on the SWC-50 board.
(3) Infrared remote control demodulation
The RM-224 board has an IC (IC1) for infrared remote control signal demodulation, and it receives the
command codes via IC100 on the KSW-55 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-273 board. This IC1001
read 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-273
board, and it is posted to the system controller as the input voltage value.
(6) Power system control
IC1001 on the RE-273 board checks that the power switch on the PMW-EX1R is turned ON, and turns on
the system controller of IC2900. 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-272 and RE-273 boards
according to the operation mode of the device, via the power supply μ-processor (IC1001) on the RE-273
board.
By turning off the power systems to unnecessary circuits blocks, power can be saved.
7. EVF/SDI System
SDI block
TX-131 Board
This board receives the parallel video signal with FPGA (IC200) and outputs the SDI signal.
Furthermore, it performs audio or timecode embedding.
The video and audio signals are supplied from CN700 on the DPR-311 board to CN100 on the TX-131
board with B to B connector.
Output SDI signals are supplied to CN500 through the cable driver (IC500).
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 (IC200) is controlled by IC600 on the DPR-311 board through 4-line serial communication.

1-10 (E) PMW-EX1R
8. Power supply system
RE-272/273 Board
This board is comprised of the power supply circuit and the POWER SUPPLY MICON (power supply
μ-processor: IC1001 on the RE-273 board).
However, part of the low-voltage power supply is mounted on the DPR-311 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 μ-processor: IC1001) recognizes that Power switch is
ON, the power is turned on for the system control system and the POWER SUPPLY MICON (power
supply μ-processor: IC1001) controls the power supply for each block according to the system controller
(DPR-311 board: IC2900).
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 EXT-DC. 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 operat-
ing 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 μ-processor: IC1001), and the camera shuts down. When the input power supply voltage be-
comes higher than +10.5 V, the power supply immediately switches on with automatic recovery accord-
ing to the control by the POWER SUPPLY MICON (power supply μ-processor: IC1001)
.Overcurrent detection
The overcurrent detection circuit is comprised of IC308 on the RE-272 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.
.Power supply reverse connection protection
If the input power has reverse voltage, Q301 on the RE-272 board is immediately turned off and UN-
REG power is stopped on the GND side, and the protection function works.
.Power saving function during standby
When the power switch of the camera is turned off, the POWER SUPPLY MICON (power supply
μ-processor: IC1001) enters the Sleep mode in order to save the power by minimizing the detection
circuit of the camera power switch.

1-11 (E)
PMW-EX1R
(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 μ-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.
(3) 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 speci-
fied 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 infor-
mation about the battery, including whether the battery is damaged or how long the life is, in order to
provide optimal operations.
