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 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.
