Description
The MT90863 Rate Conversion Switch provides
switching
capacities
of
between backplane and local streams, and 512 x
512 channels for local streams. The connected serial
inputs and outputs may have 32, 64 and 128 64kb/s
channels per frame with data rates of 2.048Mb/s,
4.096Mb/s and 8.192Mb/s respectively.

channels
The MT90863 also offers a sub-rate switching
configuration which allows 2-bit wide 16kb/s data
channels to be switched within the device.
The device has features (such as: message mode;
input and output offset delay; direction control; and,
high
impedance
output
programmable on per-stream or per-channel basis.
