Patent ID: 6973146

Claim:
A bit pump having a transmit and receive path, comprising: a precoder, coupled to said transmit path, that preconditions a transmit signal propagating along said transmit path; a modulator, coupled to said precoder, that reduces a noise associated with said transmit signal; an analog-to-digital converter, coupled to said receive path, that converts a receive signal received at said bit pump into a digital format; a resampler, coupled to said analog-to-digital converter and an oscillator of said bit pump, including: an interpolation stage, coupled to an input of said resampler, that receives a one-bit input signal representing at least a portion of said receive signal and generates a plurality of intermediate samples from at least two input samples associated with said one-bit input signal, and a selection stage, coupled to said interpolation stage, that selects one of said plurality of intermediate samples thereby providing an output sample that corresponds to a phase of said oscillator, and an echo canceling system, coupled between said transmit and receive path, that attenuates an echo in said receive signal.
