Description

Connect a resistor between this

pin and GND1 to control the

internal LPF and trap

frequencies.

Connect a 33kΩ resistor

(tolerance ±2%, temperature

characteristics ±200ppm or less).

This pin is easily affected by

external noise, so make the

connection between the pin and

external resistor, and between

the GND side of the external

resistor and the GND1 pin as

close as possible.

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 and PSIG output

circuits)

R, G, B and PSIG 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.
