MT90863AG2 [MICROSEMI]

The MT90863 is a rate conversion switch that supports switching between backplane and local streams with capacities of 2,048 × 512 and 512 x 512. It handles data rates of 2.048, 4.096, and 8.192 Mb/s, and offers sub-rate switching for 2.048 Mb/s streams. Features include per-channel variable or constant throughput delay, compatibility with HMVIP and H.100 specifications, automatic frame offset delay measurement, per-stream frame delay offset programming, per-channel message mode, per-channel direction control, per-channel high impedance output control, and support for ST-BUS, HMVIP and H.100 interfaces. It has a non-multiplexed microprocessor interface, connection memory block programming, 3.3 V local I/O with 5 V tolerant inputs and TTL-compatible outputs, and IEEE-1149.1 (JTAG) Test Port.
