Backplane Serial Input Streams 0 to 15 (5 V Tolerant, Internal pull-
down).
In Non-32 Mb/s Mode, these pins accept serial TDM data streams
at a data-rate of:
16.384 Mb/s (with 256 channels per stream),
8.192 Mb/s (with 128 channels per stream),
4.096 Mb/s (with 64 channels per stream), or
2.048 Mb/s (with 32 channels per stream).
The data-rate is independently programmable for each input stream.
In 32 Mb/s Mode, these pins accept serial TDM data streams at a fixed
data-rate of 32.768 Mb/s (with 512 channels per stream).

Backplane Serial Input Streams 16 to 31 (5 V Tolerant, Internal pull-
down).
In Non-32 Mb/s Mode, these pins accept serial TDM data streams at a
data-rate of:
16.384 Mb/s (with 256 channels per stream),
8.192 Mb/s (with 128 channels per stream),
4.096 Mb/s (with 64 channels per stream), or
2.048 Mb/s (with 32 channels per stream).
The data-rate is independently programmable for each input stream.
In 32 Mb/s Mode, these pins are unused and should be externally
connected to a defined logic level.
