Description
RGB output DC voltage
control.
When used with a VCC2 of
12V or more, apply 6V from
an external source.
Color difference demodulation
circuit inputs.
Color difference signal is input
when using Y/color difference
input. At this time, the clamp
level is approximately 2.8V.
Pin 52 signal is input in other
modes. (except D-PAL∗1) At
this time, the DC level is
approximately 2.0V.
Color adjusted chroma signal
output. The burst level is
approximately 140mVp-p (typ.).
(420mVp-p during D-PAL.)

∗1 D-PAL is a demodulation method that uses an external delay line during demodulation; S-PAL is a demodulation
method that internally processes chroma demodulation.
