Preliminary Information
MT88V32
3-55
Figures 4, 5 and 6 show methods of interfacing the
MT88V32 to Motorola and Intel microcontrollers. The
address decoding for these configurations is in Table
3.
Video Signal Terminology
1) Component Video - separate red (R), blue (B),
green (G), and synchronization signals.
2) Composite
(brightness),
synchronization signal components in a single
waveform.
Video
chrominance
-
contains
luminance
(colour),
and
3) Synchronization signal - horizontal sync pulses
are negative going excursions of the composite
video signal that occur every 63.5 μsec. Their
function is to align the horizontal sweep.
Vertical synchronization is achieved during the
vertical blanking interval, which is about 1200
μsec or 20 horizontal scan intervals long. It
consists of a number of vertical synchronization
and equalization pulses.
4) Luminance - is the black to white brightness
component of a composite video signal. Its range
is from reference white (maximum amplitude) to
reference black (minimum amplitude).
5) Chrominance - rides on the luminance signal and
determines the hue (phase) and brightness
(amplitude) of the colour component of a
composite video signal.
6) Colour burst - is about 9 (minimum 8) cycles of a
3.578545 MHz reference signal, which is
transmitted with every horizontal sweep of the
composite video signal. A phase comparison
