Abstract

We have designed and measured single flux quantum (SFQ) circuits for data switching at 2.5 Gbps. A fully functional 2/spl times/2 switching node is presented. The node can be used to form a larger switching fabric (4/spl times/4, 8/spl times/8, etc.). The node accepts data streams at either or both inputs, routing the data based on address bits present in the data stream. This approach allows the data to be self-routing and the switch to be self-synchronous. In addition, the switch can route data correctly on an active input line if the other is idle.
