Description
VCC
For setting the reference current inside the IC
(mainly, Y color difference signal processing
system).
Connect to GND via the 22kΩ resistor (such
as a metal film resistor) with an error of less
than 1%.

The pin voltage is approximately 2.6V.
GND
Power supply for Y color difference signal
processing system.
VCC
Input the selector output YCbCr (Pins 76, 77,
78) signals through a clamping capacitor.
Signals are input at a 0.7Vp-p 100 IRE level
(but only with 100% color bars for CbCr). The
pedestal is clamped to 4.9V.

VCC
IN2 to IN5 selector outputs.
YCbCr-converted signals are output.
These pins can be connected to an external
processor, etc.
Signals are output at a level equivalent to
0dB compared with the IN2 to IN5 input level.
The conversion types are shown on the
pages with the description of operation.
Select these signals with I2C bus "MAT-OUT."
