Figure 7. Phase Comparator
The sync-pulse drives the current in the compara-
tor. The line flyback integrated by the external net-
work gives on pin 11 a saw tooth, the DC offset of
this saw tooth is fixed by VC. The comparator out-
put provides a positive current for the part of the
signal on pin 11 greater than to VC and a negative
current for the other part.When the line flyback and
the video signal are synchronized, the output of
the comparator is an alternatively negative and
positive current. The frame sync-pulse inhibits the
comparator to prevent frequency drift of the line
oscillator on the frame beginning.
