PIN NAME
CC
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.
The GND pin of DEF block.
Connect the filter for horizontal
AFC.
The frequency of the horizontal
output varies depending on the
voltage at this pin.
Connect the ceramic oscillator for
horizontal oscillation.
The oscillator to be used is
CSBLA503KECZF30, made by
Murata electronics.
The V
Connect 9V (Typ.) to this pin.
Produces the horizontal output.
Connecting the DEF V
pin can swich Double Scan mode.
In this case, the horizontal output is
not produced.
