Description

The MT90823 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 MT90823 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.

Per stream input delay control of MT90823 is particularly useful for managing large multi-chip switches that transport both voice channel and concatenated data channels.

In addition, the input stream of MT90823 can be individually calibrated for input frame offset using a dedicated pin.
