Description
1
Power supply 12 V (VCC ): Supply pin, Apply DC 12 V.
Frequency-divided output 1:
2
Frequency-divided output of V-sync.: f in6/2
Outputted with current
Frequency-divided output 2 on/off:
3
On/off changeover pin for frequency-divided output 2,
Off at 0 V.
Frequency-divided output 2 control input:
4
Control input pin for frequency-divided output 2,
Apply DC 0 V to 5 V.
Frequency-divided output1 control input:
5
Control input pin for frequency-divided output1
Apply DC 0 V to 5 V.
V-sync. input:
6
Input pin for V-sync.
Input negative polarity pulse.
7
GND1: Ground pin
H-sync. input:
Input pin for H-sync.
8
Possible to input with both polarities, but phase will be delayed by a pulse width if
pulse is inputted with positive polarity.
