NJW1303
SYNCHRONOUS SEPARATOR WITH COUNT DOWN
TGENERAL DESCRIPTION
The NJW1303 is a synchronous separator performs
Horizontal and Vertical synchronous signal from composit video
signals. It contains count down circuit for H,V keeping high sync
separation in the weak signal. It is suitable for car navigation and
LCD TV.
