MOTOROLA ANALOG IC DEVICE DATA
The MC1378 is a bipolar composite video overlay encoder and
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.
Contains All Needed Reference Oscillators
Can Be Operated in PAL or NTSC Mode, 625 or 525 Line
Wideband, Full–Fidelity Color Encoding
Local or Remote Modes of Operation
Minimal External Components
Designed to Operate from 5.0 V supply
Will Work with non standard Video
