Function descriptions
fSC VCO input pins. Connect a
3.58 MHz oscillation filter between
pins 27 and 28 and a 4.43 MHz
oscillation filter between pins 27
and 29. Switch of pin 28 input and
pin 29 input is suppressed in
response to pin 41 (fSC switch)
voltage.
Pin for connecting filter of chroma
APC detector.
