Description

The MT90826 Quad Digital Switch has a nonblocking switch capacity of 4,096 x 4,096 channels at a serial bit rate of 8.192Mb/s or 16.384 Mb/s, 2,048 x 2,048 channels at 4.096Mb/s and 1024 x 1024 channels at 2.048Mb/s. The device has many features that are programmable on a per stream or per channel basis, including message mode, input offset delay and high impedance output control.

 The per stream input and output delay control of MT90826 is particularly useful for managing large multi-chip switches with a distributed backplane.

Operating in Split Rate mode of MT90826 allows for switching between two groups of bit rate streams.
