Logic output pin for horizontal synchro-
nous signal
When pin
input signal is POSI, outputs
"H"; when NON, outputs "L"; and when
NEG, outputs "H".

Logic output pin for vertical synchronous
signal
When pin
input signal is POSI, outputs
"H"; when NON, outputs "L"; and when
NEG, outputs "H".

This SW is available to change the gener-
ating position of clamp pulse for input sig-
nal. (See Table 2.)

VTH M =1.6 to 2.8V
VTH H =3.4 to 5V

GREEN (SYNC ON VIDEO) input pin
Input with negative sync.
Comparison of pin
erence voltage within the IC performs
synchronous separation.

≈
2.5V when
open
Composite sync/H sync input pin.
Bias is approx. 2.5V and impedance is
10k
.
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
DET
≈
2.5V when
open (no sig-
nal)
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
response speed of detection.
