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 mode,
input bit delay, output bit advancement, constant throughput delay, high impedance output control for both local and
backplane streams and the driven-high backplane output control.
