Circuit operation
(1) Synchronization separation circuit
Detects the charging current to a externally-connected
capacitor, and performs synchronization separation.
(2) Horizontal oscillation circuit
When a video signal is input, it is synchronized with
Hsync by the PLL. The horizontal free-running frequency
is determined by external resistor R1.
(3) Vertical synchronization separation circuit
When a video signal is input, synchronization signal
separation is done over the vertical synchronization
pulse interval.
