Abstract--A high-isolation, 16 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 rms output jitter of 4 ps. Single channel operation output
jitter below 2.8-ps rms 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.
Index Terms--Bipolar intergated circuits, communication
switching, electronic switching systems, Gallium Arsenide, het-
erojunction bipolar transistors, III­V semiconductors, high speed
integrated circuits, current mode logic, jitter.
