SYNC.
output
Output the synchronizing signal
that was separated in the
synchronous separation circuit.
This pin is of the open collector
system. Connect the pull-up
resistor.
19 DEF GND The GND pin of DEF block.
20 AFC filter
Connect the filter for horizontal
AFC.
The frequency of the horizontal
output varies depending on the
voltage at this pin.
