A 10 Gb/s 12x12 cross-point switch implemented with AlGaAs/GaAs heterojunction bipolar transistors

A 12x12 cross-point switch is reported which operates with data rate per channel of 10 Gb/s. The aggregate data rate for the switch, 120 Gb/s, is one of the highest of any reported IC. The circuit is based on AlGaAs/GaAs HBT technology and employs a double switching architecture to minimize jitter. An rms jitter below 4 psec has been demonstrated.
