Description
12V power supply.
4.5V power supply.
RGB output DC voltage
control.
When used with a VCC2 and
VCC3 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
standard signal input level is
0.3Vp-p and the clamp level is
approximately 2.8V. Pin 53
signal is input in other modes
(except D-PAL∗). At this time,
the DC level is approximately
1.6V.
Color adjusted chroma signal
output.
The burst level is 180mVp-p
(typ.).
(540mVp-p during D-PAL.)
Leave this pin open when
using Y/color difference input.

∗ 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.
