Horizontal Synchronous Detection
Output Pin :
The phase between horizontal
synchronous signal and horizontal
output pulse is detected
When synchronising comes off, Pin18
voltage goes low
When not synchronising,color
control is minimum,and chroma output
disappears
In the case where Pin18 voltage is used
by MICOM, impedance has to be taken
care(Zo
1 M
is required)
