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.

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
