The MSC III SDA 9220-5 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 SDA 9220-5 offers a number of special operating modes.

The MSC III SDA 9220-5 is set via the I2C Bus, it being possible to switch the I2C 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) of SDA 9220-5 are also generated.
