Description
The
MT90823
non-blocking switch capacity of: 2,048 x 2,048
channels at a serial bit rate of 8.192 Mb/s; 1,024 x
1,024 channels at 4.096 Mb/s; and 512 x 512
channels at 2.048 Mb/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.

a
Per stream input delay control is particularly useful
for managing large multi-chip switches that transport
both voice channel and concatenated data channels.
In addition, the input stream can be individually
calibrated for input frame offset using a dedicated
pin.
