SYNC SIGNAL PROCESSOR

DESCRIPTION OF PIN (cont.)

Pin No.

Name

Pin voltage

Peripheral circuit of pins

0.1mA

Description of function

V TIME GATE SW pin

Can select whether to output the pulse of

14 15

VD portion from pin

output pluse.

The threshold voltage is approx. 2.5V.

VTH L=0 to 2V

VTH H=3 to 5V

V.TEME

GATE SW

≈3.2V when

open

2.5V

30kΩ

20kΩ

V S/S IN pin

Inputs a signal of having externally inte-

grated composite sync for V sync separa-

tion.

4kΩ

0.1mA

7.5kΩ

V S/S

1kΩ

5.5kΩ

1.75kΩ

20kΩ

0.2mA

V S/S pulse output pin

1kΩ

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 synchro-

nous signal

When pin input signal is POSI, outputs

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

NEG, outputs "H".

0 VDC or

5 VDC

H.POL.

Logic output pin for vertical synchronous

signal

When pin input signal is POSI, outputs

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

NEG, outputs "H".

0 VDC or

5 VDC

V.POL.

Same as pin

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.
