Function
Logic output pin for horizontal
synchronous signal
When pin 6 input signal is POSI,
outputs "H"; when NON, outputs "L";
and when NEG, outputs "H".
Logic output pin for vertical
synchronous signal
When pin 8 input signal is POSI,
outputs "H"; when NON, outputs "L";
and when NEG, outputs "H".
This SW is available to change the
generating position of clamp pulse for
input signal. (See Table 2.)
VTH L = 0 to 1 V
VTH M = 1.6 to 2.8 V

The internal double threshold
comparator is used for shaping
waveform and detecting polarity.
Optimum input amplitude is 0.6 VP-P
at pin 6. Up to approx. 50% of duty,
waveform shaping and polarity
detection can be done.
