Patent ID: 6891910

Claim:
A baud-rate timing recovery system for recovering timing information from a transmitted signal, the system comprising: a sampler having first and second inputs and an output, the first input adapted to receive a transmitted signal, the second input adapted to receive a clock signal, the sampler operative to sample a transmitted signal according to the clock signal; a DFE having an input and first and second outputs, the input coupled to the output of the sampler, the DFE having a first pre-cursor tap providing the first output and a first post-cursor tap providing the second output; and a timing error detector having first and second inputs and in output, the first input coupled to the first output of the DFE and the second input coupled to the second output of the DFE, the liming error detector operative to provide at the output a signal that includes a ratio of the first and second inputs, wherein the signal is representative of the timing error reflected in the sampled transmitted signal, the signal provided at the output of the timing error detector being used to derive the clock signal at the second input of the sampler.
