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