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.

Description of Operation – Refer to Figures 3, 4
Remote Mode
Local 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:
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 the incoming horizontal sync. It is fast acting, to follow
VCR source fluctuations.
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
PD3
PD4
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
active, but providing an arbitrary phase shift setting
between the color oscillator and the output burst phase.
controls an internal phase shifter to assure that the
outgoing color burst is the same phase as incoming burst
at PD3.
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.

Vertical lock is obtained by continuously resetting the sync
COMPOSITE VIDEO GENERATION
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.
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.
