CXA2000Q

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.

E-WOUT

V parabola wave output.

VAGCSH

Sample-and-hold for AGC which

maintains the V sawtooth wave at a

constant amplitude.

Connect to GND via a capacitor.

SAWOSC

Connect a capacitor to generate the V

sawtooth wave. For the capacitor, use an

MPS (metalized polyester capacitor), etc.,

with a small tan

δ.

DVCC1

Power supply for the V deflection block.

HD OUT

H drive signal output.

This signal is output with the open

collector.
