Abstract:
1. A signaling system comprising: a first integrated circuit (IC) device to receive a data signal and a strobe signal and having circuitry to sample the data signal at times indicated by the strobe signal to generate phase error information and circuitry to output the phase error information from the first IC device, the circuitry to sample the data signal including a data sampling circuit to sample the data signal in response to the strobe signal to generate a sequence of data samples, and an edge sampling circuit to sample the data signal in response to a phase-shifted version of the strobe signal to generate a sequence of edge samples; and a second IC device to output the data signal and the strobe signal to the first IC device, the second IC device having delay circuitry to generate the strobe signal by delaying an aperiodic timing signal for a first time interval and timing control circuitry to receive the phase error information from the first IC device and adjust the first time interval in accordance with the phase error information.
