Abstract
A Rapid Single-Flux-Quantum (“RSFQ”) encoder output interface device is provided. The RSFQ output interface device includes a variable phase multi-junction voltage controlled oscillator (VCO) that provides multiple clock signals having similar frequencies based on a DC bias current setting. The multiple clock signals are phase shifted from one other based on a flux bias current setting. The clock signals are then mixed together according to logic states of a data stream to provide an encoded output data stream. The encoded output data stream can be in a phase shifted keying (PSK) format. The PSK format can be provided in binary, quadrature or other PSK formats. The Single-Flux-Quantum (SFQ) voltage pulses of the encoded output data stream are converted to a voltage level appropriate for transmitting over a wire.
