PIN NAME
(9V)
The V
color difference blocks.
Connect 9V (Typ.).
The half-tone switch for internal
RGB signal.
When the voltage at this pin is set to
7.0V or more, the RGB output
voltage.
Outputs the Y-signal that routed
HPF after it had been subjected to
DC restoration.
The output is muted with the
switches of pins 32 and 36.
Connect the filter correcting DC
restoration ratio.
Opening this pin can monitor the
Y-signal that was subjected to black
stretching.
Connect the filter controlling the
black stretching gain of the black
stretching circuit.
The black stretching gain varies
depending on the voltage at this pin.
