Function
Connected to X'tal. Oscillation frequency f0 and frequency
adjustment range can be changed in series capacity and parallel
capacity respectively.
Frequency adjustment range for oscillation frequency f0 with
series capacity can be changed to parallel capacity.
Connected to the chroma demodulation APC filter.
VCXO oscillation frequency is determined by the voltage of this pin.
Chroma processing circuit GND pin.
Chroma input pin.
Inputs Y/C separated chroma signal.
Connected to the filter for vertical sync separation.
Sync separation circuit input.
Outputs the sync signal separated in the sync separation circuit.
Connected to the filter for horizontal AFC.
Horizontal output frequency is determined by the voltage of this pin.
GND pin of the sync processing circuit.
Connected to the ceramic oscillator for horizontal oscillation.
Vertical pulse output.
Outputs the HD pulse imposed with AFC.
