    Abstract: Technology for a phase detector is described. The phase detector can include a reference clock. The phase detector can include a feedback clock. The phase detector can include a first latch operable to set a first latch output depending on a lead-lag status between the reference clock and the feedback clock. The phase detector can include a second latch that loads the lead-lag status when the reference clock and the feedback clock produce clock signals in a high state. The phase detector can include a third latch that loads the lead-lag status from the second latch when the reference clock and the feedback clock produce clock signals in a low state.

    Abstract: In one aspect of the teachings herein, a timing circuit detects the assertion of an incoming timing pulse signal at a timing resolution higher than that afforded by the sampling clock signal used to detect the assertion event. To do so, the timing circuit uses delay circuitry to obtain incrementally delayed versions of the incoming timing pulse signal or sampling clock signal. The delay increments are fractions of the sampling clock period and the timing circuit uses the delayed versions to determine a timing difference between actual assertion time of the incoming timing pulse signal and the sampling clock edge at which assertion of the incoming timing pulse signal is detected. In another aspect, a timing circuit uses similar delay techniques to control the timing of an outgoing timing pulse signal at a timing resolution higher than that afforded by the clock circuitry associated with generating the outgoing signal.

    Abstract: An integrated circuit device includes a delay circuit, sampling circuit and delay control circuit that cooperate to carry out adaptive timing calibration. The delay circuit generates a timing signal by delaying an aperiodic input signal for a first interval. The sampling circuit samples a data signal in response to the timing signal to generate a sequence of data samples, and also samples the data signal in response to a phase-shifted version of the timing signal to generate a sequence of edge samples. The delay control circuit adjusts the first interval based, at least in part, on a phase error indicated by the sequence of data samples and the sequence of edge samples.

    Abstract: A synchronous clock signal can be adjusted relative to a data signal by decreasing a delay in the synchronous clock signal if a transition of a data signal occurs before a pulse of an offset clock signal which is delayed by one half cycle relative to the synchronous clock signal. The synchronous clock signal can be delayed if the transition of the data signal occurs after the pulse of the offset synchronous clock signal.
