Description
The MT90868 Digital Switch provides switching
capacities of 32,768 x 8,192 channels between
backplane and local streams, 8,192 x 8,192
channels among local streams and 1,024 x 1,024
channels among two selected backplane streams.
The local port has sixty-four input and sixty-four
output streams which operate at 8.192Mb/s. The
backplane port has sixty-four input and sixty-four
output streams which operate at 16.384Mb/s or
32.768Mb/s.
The MT90868 has features that are programmable
on per-stream or per-channel basis including
message
advancement, constant throughput delay, high
impedance output control for both local and
backplane streams and the driven-high backplane
output control.
