    摘要: A low gain phase-locked loop circuit comprising a phase detector, a plurality of voltage controlled oscillators, wherein each voltage controlled oscillator is selectable to provide an output clock signal based at least in part on information generated by the phase detector; and a multiplexer to output a signal generated by one of the voltage controlled oscillators as the output clock signal based on a multi-bit selection control signal.

    摘要: According to some embodiments an apparatus comprising a vote generator, a vote governor, and a local clock controller is provided. The vote generator generates votes based on a local clock signal and transitions in a stream of received data. The vote governor receives the generated votes and discards at least some of the votes. The local clock controller adjusts the local clock signal based on a generated vote that has not been discarded.

    摘要: A method and apparatus for retraining skew compensation in an interface is presented. In one embodiment, a retraining interval is determined, and counters in the transmitting agent and receiving agent count up until the retraining interval is reached. A tracking unit used to select one of several interpolated clocks may then be powered up, and a special retraining phit may be sent across the interface. During the retraining process, the transfer of flits into and out of the flow-control mechanism may be inhibited. When the retraining process is finished, the tracking unit may be powered down.
