Claim 1:
2. The method for reliably receiving data claimed in claim 1, wherein:
preparing the non-equalized signal for extraction of data by processing the non-equalized signal using the physical layer transceiver comprises preparing the non-equalized signal for extraction of data by processing the non-equalized signal using the physical layer transceiver that has been configured to:
reduce jitter in the non-equalized signal by:
detecting, using a timing error detector, a timing error based on the non-equalized signal received at the physical layer transceiver; and
adjusting, using a phase interpolator, a sample clock phase of an analog-to-digital converter sample clock to compensate for the timing error;

improve the signal-to-noise ratio of the non-equalized signal by:
generating, using the matching filters, a filtered signal based on the non-equalized signal received at the physical layer transceiver;

compensate for noise or interference distortion in the non-equalized signal by:
detecting, using peak search circuitry, peak values in the filtered signal;
tracking, using peak tracking circuitry, the peak values to identify an optimal value among the peak values; and
synchronizing a sample phase used by the data select circuitry based on the identified optimal value;

the method further comprises generating, using a Differential Manchester Encoding (MDE) decoder, a decoded signal based on the filtered signal; and
selecting, using the data select circuitry, a logic zero or a logic one is based on the decoded signal and the sample phase.
