RinS1

This pin is for input a right audio

signal from an external source (S1

channel). The signal fed into this pin

is presented to Rout1 and Rout2.

13

The input dynamic range of this pin

is 6.5 Vp-p and the input resistance is

70 kΩ.

CinS1

This pin is for input a chroma signal

from an external source (S1

channel). It also functions as an

S-mode select switch for the S1

channel. The S mode is selected

when the pin voltage is 2.25 V or

less. The signal fed into this pin is

presented to Cout directly and to

14

Vout1 and Vout2 after being

combined with the YinS1 signal.

The input dynamic range of this pin

is 2.0 Vp-p and the input resistance is

30 kΩ.

LinS2

This pin is for input a left audio

signal from an external source (S2

channel). The signal fed into this pin

is presented to Lout1 and Lout2.

Y/VinS2

This pin is for input a luminance

signal or composite aoudio signal

from an external source (S2

channel). The signal fed into this pin

is presented to Vout1, Vout2, Yout,

and Cout.

16
