1. A signal transmission system comprising:
an equalization filter configured to filter an input signal based at least in part on a feedback signal;
a slicer coupled to the equalization filter and configured to compare the filtered input signal sampled at a plurality of different phases with a threshold and to generate a binary output per unit sample;
a synchronizer coupled to the slicer and configured to compute a phase delay between the input signal at each of the different phases and the binary output for each of the unit samples;
a pattern generator coupled to the synchronizer and configured to generate the feedback signal at a phase adjusted by the phase delay;
a de-serializer coupled to the slicer and configured to parallelize the sampled signal;
a serializer coupled to the equalization filter and configured to serialize the feedback signal; and
a synchronous replica path coupled between the serializer and the de-serializer.
