A 1.544 / 6.176 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 1.544 MHz.
Marks the beginning of every transmit multiframe or optionally
every 12 frames.
Marks the time-slots which are defined by register TTR1-4 of
every frame at port XDI. Optionally in CAS-BR applications the
robbed bits are marked every six frames.
Marks the DL-bit position within the data stream on XDI.
Frequency: 1.544 MHz
