Output signals
The output sync controller generates horizontal and vertical synchronization signals for
the scan rate converted output signal. The figure below shows the block diagram of the
OSCM/S and the existing I²C Bus parameters.

Furthermore the output sync controller derives framing signals from the generated
HOUT and VOUT for the output data processing. The framing signals depend on
different I²C Bus parameters. The whole output picture is a combination of three
channels:
