GND

Adjusts delay time of R and B

output for G output. The delay

time is adjusted by changing

the resistance value between

this pin and GND. The B

output delay time is twice the R

output delay time.

Connecting this pin to VCC

turns off the R output and B

output delay circuits.

Fine adjustment for R and B

signal contrast. This pin is

preset internally.
