Data Sheet
Description
The MT90820 Large Digital Switch has a 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 per stream or per channel basis, including message mode, input offset delay
and high impedance output control.
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, input stream can be individually calibrated for input frame offset using a dedicated pin.
