The
MC44002/7 is a highly advanced circuit which performs most of the
basic
functions required for a color TV. All of its advanced features are
under
processor
control via an I2C bus, enabling potentiometer controls to
be
removed
completely. In this way the component count may be reduced
dramatically,
allowing significant cost savings together with the possibility
of
implementing
sophisticated automatic test routines. Using the
MC44002/7,
TV
manufacturers will be able to build a standard chassis for anywhere in
the
world.
Additional features include 4 selectable matrix modes (primarily
for
NTSC), fast
beam current limiting and 16:9 display.
