MT90826AV [Microchip]

The MT90826 Quad Digital Switch is a non-blocking switch with capacity of 4,096 x 4,096 channels at 8.192 or 16.384 Mbps, 2,048 x 2,048 at 4.096 Mbps, and 1024 x 1024 at 2.048 Mbps. It accepts 32 ST-BUS streams of 2.048, 4.096, 8.192, or 16.384 Mbps. Features include per-channel variable or constant throughput delay, Split Rate mode for rate conversion, automatic frame offset delay measurement, per-stream input and output delay programming, per-channel high impedance output control, bit error monitoring, per-channel message mode, connection memory block programming, IEEE-1149.1 (JTAG) test port, and 3.3 V local I/O with 5 V tolerant inputs. The per-stream input and output delay control is useful for managing large multi-chip switches with a distributed backplane.
