RinV2

(29)

This pin is for input a right audio

signal from an external source (V2

channel). This pin can also be used

for PIP signal input. The signal fed

into this pin is presented to Rout1

and Rout2.

Cin

(30)

33

VCC

(33)

This pin is for input a chroma signal

from an external comb filter. The

signal fed into this pin is presented

to Cout.

The input dynamic range of this pin

is 5.5 Vp-p and the input resistance is 32

60 kΩ.

(30)

This pin also functions as a audio

mute switch. The entire audio output

can be muted by pulling the voltage

on this pin below 2.25 V.

This is the power supply pin. Apply 9

V to this pin. The current

consumption of this pin is 47 mA.

(34)

This pin is for output a chroma

signal. The signal fed into Cin,

CinS1, CinS2, VinV1, VinV2,

Y/VinS1, Y/VinS2, or VinTV is

outputted from this pin. The output

resistance of this pin is 25 Ω.
