Abstract

In an exemplary system, a first sampling circuit is coupled to a clock module to receive values therefrom. A second sampling circuit is coupled to the clock module to receive the values therefrom. The first sampling circuit includes a first converter, a first phase interpolator, and a first sampler. The first converter is coupled to replace the values with first replacement values for input to the first phase interpolator. The second sampling circuit includes a second converter, a second phase interpolator, and a second sampler. The second converter is coupled to replace the values with second replacement values for input to the second phase interpolator.
