Abstract

A high-isolation, 16/spl times/16 crosspoint switch is reported, capable of aggregate data throughput of 160 Gb/s with low crosstalk and output jitter. Each of the 16 fully asynchronous channels can transmit data at rates up to 10 Gb/s with a worst case r.m.s. output jitter of 4 ps. Single channel operation output jitter below 2.8 ps r.m.s. has been demonstrated. The high-isolation circuitry allows for inter-channel crosstalk isolation of more than 40 dB with all channels operative. The circuit is based on AlGaAs/GaAs heterojunction bipolar transistor technology.
