Description
Inputs the vertical separate sync.
Inputs at TTL level and polarity is
positive/negative.
V Low
≤
0.5V
V High
≥
4.5V
Connect a pull-down resistance of
470k
or less to GND.
Connection pin of an integral capacitor
for the polarity discriminator circuit
(Polarity Check); connects a 0.22μF
capacitor to GND.
When the capacitor is connected at
positive polarity: 3.4V;
negative polarity: 0.3V.
No input : 3.7V.
Vertical ramp waveform generator.
Generates a ramp waveform
synchronized to the input separate
sync frequency. Connects a 0.68μF
capacitor to GND.
The charging time constant (rising
edge) of ramp waveform is determined
by the 2k
resistance and the external
0.68μF capacitor, and the discharging
time constant (falling edge) by the
external 0.68μF capacitor and the
internal 17μA current.
When there is a verticai separate
sync, the voltage at Pin 3 rises
between 5.5 and 7.9V, existence
discrimination (Exist Check) is
performed, and an input signal is
judged to exist.
The voltage is 4.3V when no input
signal exists.
Inputs the composite and horizontal
separate sync (positive/negative
polarity). Amplitude is 1 to 5Vp-p. Input
through a capacitor.
