Data Sheet

Zarlink Semiconductor Inc.
Figure 11 - Synchronization at the Master End of the CEPT Digital Transmission Link
At the slave end of the link (Figure 10) both the DPLLs are in NORMAL mode, with DPLL #2 providing the ST-BUS
timing signals locked to the 8 kHz frame pulse (E8Ko) extracted from the received signal on the T1 line. The
regenerated frame pulse is looped back to DPLL #1 to provide the T1 line clock, which is the same as the master
end.
The 12.352 MHz and 16.384 MHz crystal clock sources are necessary for DPLL #1 and #2, respectively.
Synchronization and Timing Signals for the CEPT Transmission Link
The MT8941B can be used to provide the timing and synchronization signals for the MH89790/790B, Zarlink’s
CEPT (30+2) Digital Trunk Interface Hybrid. Since the operational frequencies of the ST-BUS and the CEPT
primary multiplex digital trunk are the same, only DPLL #2 is required.
