Switch Fabric 4K x 4K/2K x 2K/1K x 1K 3.3V 160-Pin MQFP Tray

The MT90826 Quad Digital Switch has a non-blocking switch capacity of 4,096 x 4,096 channels at a serial bit rate of 8.192 Mbps or 16.384 Mbps, 2,048 x 2,048 channels at 4.096 Mbps and 1024 x 1024 channels at 2.048 Mbps. 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. The per stream input and output delay control is particularly useful for managing large multi-chip switches with a distributed backplane. Operating in Split Rate mode allows rate conversion for switching between two groups of bit rate streams.
