Switch Fabric 2K x 2K/1K x 1K/512 x 512 3.3V 100-Pin LQFP Tray

The MT90823 Large Digital Switch has a non-blocking switch capacity of: 2,048 x 2,048 channels at a serial bit rateof 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 manyfeatures that are programmable on a per stream or per channel basis, including message mode, input offset delayand high impedance output control. Per stream input delay control is particularly useful for managing large multi-chip switches that transport both voicechannel and concatenated data channels. In addition, the input stream can be individually calibrated for input frame offset using a dedicated pin.
