Asynchronous Mode
In
asynchronous mode
, each port uses its own clock to sample and drive the data streams. Since each clock
can be at a slightly different frequency, trunking of timeslots is restricted to be within the same stream. The TDM
cross-connect switch cannot be used in asynchronous mode.
The diagram in Figure 22 shows how the device might be connected to T1/E1 framers in asynchronous mode.
Each incoming line is independently timed, bypassing the DPLL in the MT9088x device. The MT9076 contains
an integrated PLL to multiply up the line rate to the 4.096 MHz ST-bus clock.
