20. INTERLEAVED PCM BUS OPERATION
In many architectures, the outputs of individual framers are combined into higher speed serial buses to
simplify transport across the system. The DS21352/552 can be configured to allow data and signaling
buses to be multiplexed into higher speed data and signaling buses eliminating external hardware saving
board space and cost.
The interleaved PCM bus option (IBO) supports two bus speeds. The 4.096 MHz bus speed allows two
SCTs to share a common bus. The 8.192 MHz bus speed allows four SCTs to share a common bus. See
Figure 20-1 for an example of 4 devices sharing a common 8.192MHz PCM bus. Each SCT that shares a
common bus must be configured through software and requires the use of one or two device pins. The
elastic stores of each SCT must be enabled and configured for 2.048 MHz operation. See Figure 21-6
and Figure 21-7.
For all bus configurations, one SCT will be configured as the master device and the remaining SCTs will
be configured as slave devices. In the 4.096 MHz bus configuration there is one master and one slave. In
the 8.192 MHz bus configuration there is one master and three slaves. Refer to the IBO register
description for more detail.
