Name & Function

O Analog signal output pin for R channel.

O Analog signal output pin for G channel.

O Analog signal output pin for B channel.

Reference voltage input pin. This pin is used to set the analog output

dynamic range. When the internal reference voltage is used, this pin is

I connected with VROUT1 pin (36 pin) or VROUT2 pin (38 pin). When the

reference voltage is supplied from the external generator, 2.65V to

4.3V or VCCA - VRIN = 0.7V to 2.2V is input to this pin.

Reference voltage output #1 pin. The output voltage is set to 0.6 x

O

VCCA by the resistor divided method. When this pin is connected with

VRIN pin (37 pin), an analog voltage is output from this pin in a range of

0.6 x VCCA to VCCA.

Reference voltage output #2 pin. The output voltage is set to VCCA - 2V

O

by the band-gap reference method. When this pin is connected with

VRIN pin (37 pin), an analog voltage is output from this pin in a range of

VCCA - 2V to VCCA.

Phase compesation capacitor pin. A phase compesation capacitor of

0.1µF or greater is connected between this pin and A. GND pin.

— No connection, Leave those pins open.
