DESCRIPTION
Initializing input.
Input for reference clock oscillation. Connect to CKO (pin 3) with R.
Output for reference clock oscillation. The output is the inverse of CKI (pin 2).
Supply of +3.3 V power.
A grounding pin.
Clock output of AD converter, connected to pin 13 of IR3Y38M.
Clock output of serial data, connected to pin 16 of IR3Y38M.
Serial data output, connected to pin 19 of IR3Y38M.
Digital signal input, fed from pin 12 of IR3Y38M (MSB).
Digital signal input, fed from pin 11 of IR3Y38M.
Digital signal input, fed from pin 10 of IR3Y38M.
Digital signal input, fed from pin 9 of IR3Y38M.
Digital signal input, fed from pin 8 of IR3Y38M.
Digital signal input, fed from pin 5 of IR3Y38M.
Supply of +3.3 V power.
A grounding pin.
Digital signal input, fed from pin 4 of IR3Y38M.
Digital signal input, fed from pin 3 of IR3Y38M.
Digital signal input, fed from pin 2 of IR3Y38M.
Digital signal input, fed from pin 1 of IR3Y38M (LSB).
Optical clamp pulse output, connected to pin 32 of IR3Y38M.
Clamp pulse output, connected to pin 45 of IR3Y38M.
Blanking pulse output, connected to pin 35 of IR3Y38M.
Data input from EEPROM output pin.
Supply of +3.3 V power.
A grounding pin.
Clock output to EEPROM clock input pin.
This pin keeps high-impedance under high level of pin 29.
Control pin of EEPROM. Connect to the pull-up resistor.
Control pin of EEPROM. A pull-down resistor should be connected between pin
29 and GND. High level of pin 29 can make data-setting from outside available.
White balance mode setting by both WB1 and WB2.
