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.
