The MT90866 Digital Switch provides switching capacities of 4,096 x 2,432 channels between backplane and local streams, 2,432 x 2,432 channels among local streams and 2,048 x 2,048 channels among backplane streams. The local connected serial inputs and outputs have 32, 64 and 128 64kb/s channels per frame with data rates of 2.048, 4.096 and 8.192Mb/s respectively. The backplane connected serial inputs and outputs have 128 and 256 64kb/s channels per frame with data rates of 8.192 and 16.384Mb/s respectively. The MT90866 also offers a sub-rate switching configuration which allows 2-bit wide 16kb/s or 4-bit wide 32kb/s data channels to be switched within the device. |
