PIN
No.
PIN NAME
FUNCTION
INTERFACE CIRCUIT
INPUT /
OUTPUTSIGNAL
1
SCP OUTPUT
Output terminal of Sand Castle
Pulse. (SCP)
To connect drive resistor for SCP.
2
V-AGC
Controls pin 52 to maintain a
uniform V-ramp output.
Connect a current smoothing
capacitor to this pin.
3
H-VCC (9V)
VCC for the DEF block (deflecting
system).
Connect 9V (Typ.) to this pin.
4
Horizontal Output Horizontal output terminal.
5
Picture Distortion
Correction
Corrects picture distortion in high
voltage variation. Input AC
component of high voltage variation.
For inactivating the picture distortion
correction function, connect 0.01µF
capacitor between this pin and GND.
4.5V at Open
6
FBP Input
FBP input for generating horizontal
AFC2 detection pulse and horizontal
blanking pulse.
The threshold of horizontal AFC2
detection is set H.VCC-2Vf
(Vf≈0.75V).
Confirming the power supply
voltage, determine the high level of
FBP.
