An apparatus and methods for recovering a clock and a data stream from a source synchronous input data stream are disclosed. The apparatus comprises a filter, a decision feedback equalizer (DFE), a phase error detector, and a clock generator. The input data stream is coupled to the filter and the DFE. The DFE synchronizes the input data stream to a clock generated by the clock generator. A filter output and a DFE output are each coupled to the phase error detector. During an initialization period, the phase error detector conveys a phase error to the clock generator based on one or more phase error estimates of the filter output and during a period of steady-state operation, the phase error detector conveys a phase error to the clock generator based on one or more phase error estimates of the DFE output. The output of the DFE comprises a recovered data stream.
