4.2V
H deflection pulse input for H AFC.
Input an about 5Vp-p pulse via a
capacitor. Set the pulse width to 10 to
12µs. This pin is also used as the hold-
down signal input for the HD output, and
if this pin is 1V or less for a 7V cycle or
longer, the hold-down function operates
and the HD output is held to 9VDC. In
addition, the RGB outputs are all blanked.
Outputs “1” to the status register XRAY.
V parabola wave output.
Sample-and-hold for AGC which
maintains the V sawtooth wave at a
constant amplitude.
Connect to GND via a capacitor.
Connect a capacitor to generate the V
sawtooth wave. For the capacitor, use an
MPS (metalized polyester capacitor), etc.,
with a small tan .
Power supply for the V deflection block.
H drive signal output.
This signal is output with the open
collector.
