Function
1 GND 1
 GND l pin
Ground pin for circuits other than 75 Ω output driver
2 R-IN
3 G-IN
4 B-IN
I
Analog RGB input
pins
With CSYNC-IN at the “L” level, the R-IN, G-IN, and B-IN
pins are clamped. During the “L” level period, the R-IN,
G-IN, and B-IN pins input pedestal levels. (100% = 1 Vp-p)

 Unused pin

6 fsc-IN
I Subcarrier input pin Inputs a sine wave of 1.0 to 5.0 Vp-p or a pulse carrier.
7
