The MC44145, Pixel Clock Generator, is a component of the MC44000

family.

The MC44145 contains a sync separator with composite sync and vertical

outputs, and clock generation circuitry for the digitization of any video signal

along with the necessary circuitry for clock generation, such as a phase

comparator and a divide–by–2 to provide a 50% duty cycle.
