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.
