INTERLEAVED PCM BUS OPERATION
In many architectures, the PCM outputs of individual framers are combined into higher-speed PCM buses to
simplify transport across the system backplane. The DS21Q58 can be configured to allow PCM data buses to be
multiplexed into higher-speed data buses, eliminating external hardware and saving board space and cost. The
DS21Q58 uses a channel interleave method. See Figure 24-4 and Figure 24-7 for details of the channel interleave.
The interleaved PCM bus option supports three bus speeds. The 4.096MHz bus speed allows two PCM data
streams to share a common bus. The 8.192MHz bus speed allows four PCM data streams to share a common bus.
The 16.384MHz bus speed allows eight PCM data streams to share a common bus. See Figure 23-1 for an
example of four transceivers sharing a common 8.192MHz PCM bus. The receive elastic stores of each transceiver
must be enabled. Through the IBO register the user can configure each transceiver for a specific bus speed and
position. For all IBO bus configurations each transceiver is assigned an exclusive position in the high-speed PCM
bus. When the device is configured for IBO operation, the TSYNCx pin should be configured as an output or as an
input connected to ground. The user cannot supply a TSYNCx signal in this mode.
