Abstract

Various embodiments provide for phase interpolators with phase adjusters to provide step resolution, which can be used with a circuit such as a data serializer/deserializer circuit. In particular, for some embodiments, a phase interpolator is coupled to a phase adjuster, where the combination of the phase interpolator and the phase adjuster is configured to interpolate between phases in phase adjustment steps at a phase adjustment step resolution. For such embodiments, the phase adjustment step resolution of the steps is achieved by controlling the phase interpolator and the phase adjuster.
