MT90868 32,768 x 8,192 Channels High Bandwidth Digital Switch with up to 128 Streams on Backplane and 128 Streams on Local and Data Rates From 8 to 32 Mbps
| Product Status - Production |
|
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.
Features
- 32,768 channel x 8,192 channel blocking switching between backplane and local streams
- 8,192 channel x 8,192 channel non-blocking switching for local input and output streams
