摘要： Described herein are an apparatus, system and method for timing recovery in processors by means of a simplified receiver architecture that consumes less power consumption, has lower bit error rate (BER), and higher jitter tolerance. The apparatus comprises a phase interpolator to generate a clock signal; a first integrator to integrate a first portion of a data signal over a duration of a phase of the clock signal; a first sampler to sample the first integrated portion by means of the clock signal; a first circuit to store a first edge sample of the data signal; a second sampler to sample the stored first edge sample by means of the clock signal; and a clock data recovery unit to update the phase interpolator based at least on the sampled first integrated portion and sampled stored first edge sample of the data signal.
