the slave devices. The MT9088x family can also be connected as slave devices to older TDM backplanes such
as MVIP and H-MVIP buses (reference 9), either directly or through a TDM switch.
In synchronous slave mode although the DPLL is not used to sample data from the WAN TDM ports, it is still
used to provide the clocks required by the internal TDM switch. The device is able to tolerate jitter on the
primary and secondary reference clocks in excess of the G.823 and G.824 standards (references 11 and 12)
when the WAN TDM ports are run at 2.048 Mbs data rate.
