Description

Analog 3.0V GND.

Serial clock, serial load and

serial data inputs for serial

communication.

Connect a resistor for setting

the injector current of the IIL

logic circuit. Connect a 15kΩ

resistor between this pin and

GND1. Use a resistor with a

deviation of ±2% and

temperature characteristics of

±200ppm or less.

Analog 12.0V GND.

(for the RGB output circuits)

R, G and B output DC voltage

setting.

Connect a 0.01µF capacitor

between this pin and GND1.

When using a SIG.C of other

than VCC2/2, input the SIG.C

voltage from an external

source.
