DESCRIPTION:
The IDT72V71623 has a maximum non-blocking switch capacity of
2,048 x 2,048 channels with data rates at 2.048 Mb/s, 4.096 Mb/s, 8.192 Mb/s
or 16.384 Mb/s. With 16 inputs and 16 outputs, a variety of rate combinations
is supported under Mux/Demux mode, to allow for switching between streams
of different data rates.
