Description
The MT90826 Quad Digital Switch has a non-
blocking 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 is
particularly useful for managing large multi-chip
switches with a distributed backplane.
Operating in Split Rate mode allows for switching
between two groups of bit rate streams.
