Functional Description
The MSC III is a component of the TV-SAM Featurebox and is responsible for driving the picture
memory devices (TV-SAMs) and generating sync signals (
figure 6
). Together with the other
devices of the Featurebox it enhances picture quality and offers a number of special operating
modes.
The MSC III is set via the
I
2
C Bus, it being possible to switch the
I
2
C Bus address by hardware so
that implementation of a simple frame Featurebox is possible in conjunction with the signal MUX
supplied by the MSC III.
Other major output signals of the SDA 9220-5, in addition to the clocks LL3X (13.5 MHz) and LL1.5X
(27 MHz), are the memory-driving signals (RA, RB, WT, RE, SCAD, SCA) and the sync signal CSY
for the teletext device. The horizontal sync signals (HS2, BLN2) and the vertical sync signals (VS1,
VS2) are also generated.
