Input/Output
Signal
38 FBP input
The pin through which
FBP is input to generate
pulses for horizontal
AFC2, Y smoothing, and
horizontal blanking.
When double SCAM
mode, input H blanking
pulse (5 V or over).
39 NC
None connect PIN.
These pins connect to
GND.

Curve
correction
(ext.
CP/BPP
input)
(1) Used to correct
distortion of picture in
the case of
high-tension
fluctuation. Input the
AC component of
high-tension
fluctuation.
To disactivate the
distortion correction
feature, connect a
capacitor of 0.01
μ
F
between this pin and
GND.
(2) Double scan mode
This pin is to input
external CP (clamping
pulse) and BPP
(black peak detection
stopping pulse).
41
Horizontal
output
(mode SW)
Produces the horizontal
output.
Connecting the DEF V
CC
to this pin can swich
Double Scan mode. In this
case, the horizontal output
is not produced.
HIGH: 3.2 V
LOW: 0.2 V
