A 2.048 / 8.192 MHz clock has to be sourced by the system if
the internal generated transmit clock (DCO-X) should not be
used. Optionally this input functions as a synchronization clock
for the DCO-X circuitry with a frequencyof 2.048 MHz.
Marks the beginning of every transmit multiframe.
Marks the time-slots which are defined by register TTR1-4 of
every frame at port XDI.
Marks the SA8-4 bits within the data stream on XDI.
Frequency: 2.048 MHz
