Various embodiments of the present invention provide systems and methods for data processing. For example, a data processing circuit is disclosed that includes an analog to digital converter, a digital interpolation circuit, a phase error circuit, and a phase adjustment control circuit. The analog to digital converter samples an analog data input at a sampling phase governed at least in part by a coarse control, and provides a series of digital samples. The digital interpolation circuit interpolates between a subset of the series of digital samples based at least in part on a fine control. The phase error circuit calculates a phase error value. The phase adjustment control circuit is operable to determine the coarse control and the fine control based at least in part on the phase error value.
