PIN NAME
(1) Used to correct distortion of
(2) Double scan mode
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 (5V or over).
The SDA pin of I
The SCL pin of I
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 0.01µF between
this pin and GND.
This pin is to input external CP
(Clamping Pulse) and BPP
(Black Peak detection stopping
Pulse).
