Function

Blue data input pin (bit 0)

System clock input.

RGB data is taken into the IC at the timing of this clock.

GND pin for digital circuit

RGB DAC reference voltage output pin. A 0.1µF capacitor should be connected

between the GND pins.

This pin is not connected internally in the IC.

GND pin for analog circuits (other than 75Ω driver)

Analog red signal clamping pin

Power supply pin for analog circuits (other than 75Ω driver)

Analog green signal clamping pin
