Figure 12 - Synchronization at the Slave End of the CEPT Digital Transmission Link
Figures 11 and 12 show how the MT8941B can be used to synchronize the ST-BUS to the CEPT transmission link
at the master and slave ends.
Generation of ST-BUS Timing Signals
The MT8941B can source the properly formatted ST-BUS timing and control signals with no external inputs except
the crystal clock. This can be used as the standard timing source for ST-BUS systems or any other system with
similar clock requirements.
Figure 13 shows two such applications using DPLL #2. In one case, the MT8941B is in FREE-RUN mode with an
oscillator input of 16.384 MHz. In the other case, it is in NORMAL mode with the C8Kb input tied to V
DD
. For these
applications, DPLL #2 does not make any corrections and therefore, the output signals are free from jitter. DPLL #1
is completely free.
