3 CKO
OSCO
Output for reference clock oscillation. The output is the inverse of CKI (pin 2).
4 VDD
–
Supply of +3.3 V power.
5 GND
–
A grounding pin.
6 ADCK OBF6M
Clock output of AD converter, connected to pin 13 of IR3Y38M.
7 SCK
OBF4M
Clock output of serial data, connected to pin 16 of IR3Y38M.
8 SDATA OBF4M
Serial data output, connected to pin 19 of IR3Y38M.
9 ADI9
IC
Digital signal input, fed from pin 12 of IR3Y38M (MSB).
10 ADI8
IC
Digital signal input, fed from pin 11 of IR3Y38M.
11 ADI7
IC
Digital signal input, fed from pin 10 of IR3Y38M.
12 ADI6
IC
Digital signal input, fed from pin 9 of IR3Y38M.
13 ADI5
IC
Digital signal input, fed from pin 8 of IR3Y38M.
14 ADI4
IC

19 ADI1
IC
Digital signal input, fed from pin 2 of IR3Y38M.
20 ADI0
IC
Digital signal input, fed from pin 1 of IR3Y38M (LSB).
21 OBCP OBF4M
Optical clamp pulse output, connected to pin 32 of IR3Y38M.
22 ADCLP OBF4M
Clamp pulse output, connected to pin 45 of IR3Y38M.
23 BLKX OBF4M
Blanking pulse output, connected to pin 35 of IR3Y38M.
24 EEPDA IO4MU
Data input from EEPROM output pin.
25 GND
–
Supply of +3.3 V power.
26 VDD
–
A grounding pin.
27 EEPCK IO4MU
Clock output to EEPROM clock input pin.
This pin keeps high-impedance under high level of pin 29.
28 EEPFL
IC
Control pin of EEPROM. Connect to the pull-up resistor.
29 EEPSL
IC
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.
