Abstract
In one embodiment, the present invention includes a system having an amplifier to receive an incoming signal and a recovery circuit coupled to the amplifier that includes a phase detector to adjust a phase of a sampling clock via a signal indicative of a difference between transitions occurring between the sampling clock and each of a first error clock and a second error clock. Based on a phase adjusted output of the phase detector, the sampling clock may be generated with an appropriate phase. Thus, circuitry and methods are provided to reduce or eliminate phase offsets in the phase detector.
