Clock Distribution
One 12-MHz oscillator (connected to the UART-to-USB converter [FT2232HL]) and one 24.576-MHz
oscillator (connected to the audio codec [AIC3104]) are used in the CSK carrier card. In this configuration,
the audio codec is configured as the McASP and McBSP master, and the DMX processor as a McASP
and McBSP slave.
