SYNC SIGNAL PROCESSOR

DESCRIPTION OF PIN

Pin No.

Name

Pin voltage

Peripheral circuit of pins

Description of function

Logic output pin for horizontal synchro-

nous signal

20kΩ

0 VDC or

5 VDC

H.STATE

When pin input signal is POSI, outputs

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

NEG, outputs "H".

Logic output pin for vertical synchronous

signal

0 VDC or

5 VDC

V.STATE

Same as pin

When pin input signal is POSI, outputs

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

NEG, outputs "H".

0.1mA

This SW is available to change the gener-

ating position of clamp pulse for input sig-

nal. (See Table 2.)

VTH L =0 to1V

VTH M =1.6 to 2.8V

28kΩ

CLAMP

≈2.2V when

open

VTH H =3.4 to 5V

22kΩ

20kΩ 20kΩ

GREEN (SYNC ON VIDEO) input pin

Input with negative sync.

GREEN

≈2.8V when

open

Comparison of pin input signal and ref-

1kΩ

erence voltage within the IC performs

synchronous separation.

GND

Grounding

1.5kΩ

20kΩ

Composite sync/H sync input pin.

Bias is approx. 2.5V and impedance is

10kΩ.

The internal double threshold comparator

is used for shaping waveform and detect-

ing polarity. Optimum input amplitude is

0.6 Vp-p at pin . Up to approx. 50% of

duty, waveform shaping and polarity

detection can be done.

COMP/H

2.8V

2.2V

0.3mA

12kΩ

External capacitance is required as a ﬁl-

ter pin for detecting polarity and detecting

non-input. As the value is larger, the rip-

ple is smaller and less malfunction

occurs. However, this lowers the

nal)

response speed of detection.
