Color Television Composite
Video Overlay Synchronizer
microcomputer synchronizer. The MC1378 contains the complete encoder
function of the MC1377, i.e., quadrature color modulators, RGB matrix, and
blanking level clamps, plus a complete complement of synchronizers to lock
a microcomputer–based video source to any remote video source. The
MC1378 can be used as a local system timing and encoding source, but it is
most valuable when used to lock the microcomputer source to a remotely
originated video signal.

Page 2

... The MC1378 and a video system combine to provide a fully synchronized standard signal source. In this case, composite sync must be supplied by the video system or other time base system. In the MC1378 the phase detectors operate as follows: PD1 locks the internally counted–down 4 MHz horizontal VCO ...
