Can select whether to output the pulse

of VD portion from pin 14, 15 output

pulse.

The threshold voltage is approx. 2.5 V.

V S/S IN pin

Inputs a signal of having externally

integrated composite sync for V sync

separation.

V S/S pulse output pin

No problem occurs when current of

approx. 6 mA flows to internal part of

the IC. To improve the rising speed,

connect a resistance between power

supplies.

Logic output pin for horizontal

synchronous signal

When pin 6 input signal is POSI,

outputs "L"; when NON, outputs "L";

and when NEG, outputs "H".

V.POL.

0 VDC or

5 VDC

Same as pin 1

Logic output pin for vertical

synchronous signal

When pin 8 input signal is POSI,

outputs "L"; when NON, outputs "L";

and when NEG, outputs "H".

CLAMP TIMING pin

The clamp pulse width is determined

depending on the external resistance

and capacitance. As the resistance

value and capacitance value are

larger, the clamp pulse width is wider.
