Lens control block
The H-BRIDGE IC (IC1741) is used to drive IRIS and is controlled by signals from the BEAR/ETC macro in the system
processor (IC6000).
The H-BRIDGE IC (IC1742) is used to drive the second ND filter and is controlled by signals from the BEAR/ETC
macro in the system processor (IC6000) and by signals from the TPU macro. The lens control LSI (IC1803) is used to
drive the first ND filter drive and the focus lens drive and is controlled by SIO communication from the system processor
(IC6000) and the V synchronization signal.
In addition, the IC1803 detects the focus lens position, zoom lens position, and ND filter position.
The vibration-proof control and lens drive IC (IC1802) is used to drive the vibration-proof lens, zoom lens, mechanical
shutter, and infrared light cut filter and is controlled by SIO communication from the system processor (IC6000), the V
synchronization signal, and the signals form the BEAR/ETC macro.
The IC1802 also detects the vibration-proof lens position and signals from the gyro-sensor (SE7701/MS-1037 board)
for detecting shake in the PITCH direction and the YAW direction.
Wireless LAN antenna block
The WLAN module (CP7330) converts data sent from the system processor (IC6000) through SDIO communication to
RF signals conforming to IEEE802.11, and the RF signals are output from the coaxial connector (J7381) through the
coaxial harness to the WLAN antenna on the WF-1008 board.
Tip
The HXR-MC88 does not support wireless communication.
Shake (ROLL direction) detection sensor block
The signal from the gyro-sensor (SE7711) for detecting shake in the ROLL direction is amplified by the angular velocity
sensor amplifier (IC7711), and is then input to the A/D conversion macro in the system processor (IC6000).
LCD_R/G/B signal conversion block
Parallel LCD_R/G/B signals that are output from the system processor (IC6000) are converted to the SubLVDS signal
by the serial interface transmitter (IC8000).
EVF_R/G/B signal conversion block
Parallel EVF_R/G/B signals that are output from the system processor (IC6000) are converted to the SubLVDS signal
by the serial interface transmitter (IC8020).
Furthermore, the voltage level of the SIO signal level shared with the other 3 V interface device is converted to 1.8 V
interface for ECX334AF-1 using the level shifter (IC3201).
AUDIO block
Audio signals captured from the external microphone (J0801/IR-1009 board), internal 2-channel microphone (CN4603/
GR-1003 board), and multi-interface shoe microphone (CN0001/FP-2269 flexible board) are processed (including
A/D conversion, gain setting, and AGC) in the audio signal processor IC (IC8500). Then processed signals are sent to
the system processor (IC6000) through I2S communication.
