A Single Flux Quantum cross-bar switch and demultiplexer

A Single Flux Quantum (SFQ) demultiplexer and a cross-bar switch for a high speed data switch are described. Both circuits were error-free in simulation to 15 Gbps. The cross-bar switch was two input, two output (2/spl times/2) and used /spl sim/400 /spl mu/A control signals to set the data path. The switch has been demonstrated at over 15 Gbps/line using average voltage measurements. The correct routing of a bit stream was demonstrated at 2.488 Gbps.<
