Table 2-3:
FMC-Video only has one clock input and one clock output from the FMC connector.
The clock input to FMC-Video is used to drive the video encoder for the S-Video output,
typically at 27 MHz.
This clock output is needed by all of the video interfaces, which includes four sources:
DVI-Analog, DVI-Digital, the video decoder, and camera input 1. This requires a clock
multiplexor, the ICS83054I. The select lines to this multiplexor are driven by the I
Expander. The clock multiplexor circuit is diagrammed in
