MC1378 Color Television Composite Video Overlay Synchronizer
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

Description of Operation - Refer to Figures 3, 4
Remote Mode The incoming remote video signal (Pin 24) supplies all synchronizing information. A discussion of the function of the phase detectors helps to clarify the lockup method: PD1 locks the internally counted-down 4 MHz horizontal VCO to the incoming horizontal sync. It is fast acting, to follow VCR source fluctuations. PD2 locks the 36 MHz clock VCO, which is divided down by the video system, to the divided down horizontal VCO. PD3 is a gated phase detector which locks the 14 MHz crystal oscillator, divided by 4, to the incoming color burst. PD4 controls an internal phase shifter to assure that the outgoing color burst is the same phase as incoming burst at PD3. PD5 not used in REMOTE MODE Vertical lock is obtained by continuously resetting the sync generator in the video system with separated vertical sync from the MC1378, Pin 38. This signal is TTL level vertical block sync, negative going. The horizontal sync from the video system to Pin 40 is also TTL level with sync negative going. The local/remote switch, Pin 1, is in local mode when grounded, remote mode when taken to 5.0 V. The overlay control, Pin 25, has an analog characteristic, centered about 1.0 V, which allows fading from local to remote. Local Mode 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 to a Horizontal Sync signal (at Pin 40) from the video system (counted down from 36 MHz) PD2 not used in LOCAL MODE. PD3 not used in LOCAL MODE. PD4 active, but providing an arbitrary phase shift setting between the color oscillator and the output burst phase. PD5 locks the 36 MHz clock VCO (which is divided down by the video system) to the 14 MHz (crystal) color oscillator. The 14 MHz is, therefore, the system standard in LOCAL MODE, and is not DC controlled. COMPOSITE VIDEO GENERATION The color encoding at the RGB signals is done exactly as in the MC1377. Composite chroma is looped out at Pins 18 and 20 to allow the designer to choose band shaping. Luminance is similarly brought out (Pins 17 and 22) to permit installation of the appropriate delay. Composite sync output, Pin 39, and burst gate output, Pin 5, are provided for convenience only.
