V/I input
U/Q input
The pin through which R-Y
(V)/I and B-Y (U)/Q
signals are input. Input via
clamp capacitor.
When Burst: Chroma
= 1:1
360 mVp-p
DC: 5.0 V

Black peak
hold
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.
DC

APL
detection
Connect the filter
correcting DC restoration
ratio.
Opening this pin can
monitor the Y-signal that
was subjected to black
stretching.
DC
4
NC
None connect PIN.
These pins connect to
GND.
5
VSM output
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.
