Power Supply for Core Logic Circuits: +1.8 V
Ground
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.
Power Supply for Analog PLL: +1.8 V
