1. A resampler for use with a bit pump having a receive path couplable to an oscillator, comprising:
an interpolation stage, coupled to an input of said resampler via a delay stage, configured to receive separate one-bit input signals from a plurality of received signals representing at least a portion of the received signals propagating along said receive path and generate a corresponding plurality of intermediate samples from at least two input samples associated with each of said separate one-bit input signals, wherein each of the plurality of received signals is input to a separate delay line in said delay stage; and
a selection stage, coupled to said interpolation stage, configured to receive at least one of said corresponding plurality of intermediate samples via a plurality of said delay lines receiving a plurality of single bits and selecting at least one of said plurality of intermediate samples, thereby providing an output sample that corresponds to a phase of said oscillator.
