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.
