Description
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.
The device has features that are programmable on
per-stream or per-channel basis including message
mode, input delay offset, output advancement offset,
direction control and high impedance output control.
