Because the GSM adopts the TDM system, the operation of TRX relies on various clocks.
Therefore, the TRX contains the clock processing part.
Clocks of the TRX are from the clock bus of the TMU. To ensure high reliability, the clock
bus operates in active and standby modes. These clocks include frame clock, 1/8-bit clock and
FN. The clock processing part of TRX first selects the active or standby clock, and then
generates the timeslot number and bit clock that are necessary for the TRX through frequency
dividing counter.
