| | MT90868 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 8.192 Mbps. The backplane port has sixty-four input and sixty-four output streams which operate at 16.384 or 32.768 Mbps.
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. |
