Abstract
A digital clock generation system provides both a digital composite clock and a digital component clock synchronized with an input synchronization video signal. The digital composite clock is generated from the burst portion of the input synchronization video signal, and the digital component clock is synthesized from the digital composite clock. A frame timing pulse is generated at regular intervals from the composite sync of the input video signal for resetting the digital component clock to establish a defined phase relationship between the digital composite and component clocks according to an offset constant.
