    摘要: System, methods and apparatus are described that facilitate transmission of data, particularly between two devices within an electronic apparatus. A first transition may be detected in a signal carried on a data lane of a data communications link or carried on a timing lane of the data communications link and an edge may be generated on a receiver clock signal based on the first transition. Data may be captured from the data lane using the receiver clock signal. The timing lane may carry a clock signal, a strobe signal or another signal providing timing information. The strobe signal may transition between signaling states when no state transition occurs on any of a plurality of data lanes at a boundary between consecutive data periods.

    摘要: A clock recovery circuit (10) for a superconductor system that enables the phase of a system clock to be instantaneously reset without any pulse interaction. The clock recovery circuit (10) includes a Josephson transmission line oscillator loop (14) of length 2T, where T is equal to one clock period. First and second data inputs (16, 18) are for injecting a data pulse onto the oscillator loop (14). A pulse generator (24) is for injecting an initial clock pulse onto the oscillator loop (14) that is output as periodic clock signals. An output tap (12) is for outputting the data pulse from one of the first and second data inputs (16, 18), and the periodic clock signals in the absence of the data pulse. When the data pulse is input on one of first and second output taps (32, 34), the clock phase is instantaneously reset.
