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.

The MC44145 is available in a SO–14 package and is fabricated in the Motorola high density, high speed, low voltage, process called MOSAIC 1.5.
