The next stage is called the color difference stage where a
number of control functions are carried out together with
matrixing of the components to derive RGB signals. At this
point a number of auxiliary signals may also be switched in,
again all under MCU control. External RGB (text) and Fast
Commutate enter here; also an external luminance (Y2) may
be used instead of Y1. External R-Y and B-Y are switched in
via the delay line circuit to save pins on the main device. The
Y2 and External R-Y, B-Y will obviously be of considerable
benefit from the system point of view for use with external
decoders.
The final stage of video processing is the RGB outputs which
drive the high voltage amplifiers connected to the tube
cathodes. These outputs are controlled by a sophisticated
digital servo-loop which is maintained and stabilized by a
sequentially sampled beam current feedback system.
Automatic gray scale control is featured as a part of this system.
Both horizontal and vertical timebases are incorporated
into the MC44002/7 and control is via the I2C bus. The
horizontal timebase employs a dual loop system of a PLL and
variable phase shifter, and the vertical uses a countdown
system. For the vertical, a field rate sawtooth is available
which is used to drive an external power amplifier with
flyback generator (usually a single IC). The line output
consists of a pulse which drives a conventional line output
stage in the normal way. The line flyback pulse is sensed and
used by the second loop for horizontal phase shift.
Where E-W correction is required, a parabola waveform is
available for this which, with the addition of a power amplifier,
can be used with a diode modulator type line output stage for
dynamic width and E-W control. The bottom of the EHT
overwinding is returned to the MC44002/7 and is used for
anode current monitoring.
Fast beam current limitation is also made possible by the
use of an analog contrast control.
A much more detailed description of each stage of the
MC44002/7 will be found in the next section. Information on
the delay line is to be found in its own data sheet.
