Various embodiments of the present invention provide systems and methods for timing recovery. As an example, timing recovery circuits include: a first digital interpolation circuit, a second digital interpolation circuit, a phase selection circuit, and a sampling clock rotation circuit. The first digital interpolation circuit is operable to receive a data input and to provide a first interpolated output corresponding to a first phase, and the second digital interpolation circuit is operable to receive the data input and to provide a second interpolated output corresponding to a second phase. The phase selection circuit operable to select the first phase for processing, and the sampling clock rotation circuit is operable to move a sampling clock away from the first phase.
