Abstract
A device includes a transmitter to generate a sampled stream of data for a packet at a first sample rate. A data re-sampling circuit includes a re-timer engine to determine, using a fractional rate between the first sample rate and a crystal oscillator (XO)-divided sample rate, re-timer values including a difference between pulses of a pseudo-clock corresponding to the XO-integer-divided sample rate and closest corresponding pulses of a clock corresponding to the first sample rate, and a time-shifting circuit to re-sample data values of the sampled stream of data associated with locations of the plurality of re-timer values. A comparator circuit uses the re-sampled data values to match the re-sampled data values to a corresponding data value detected in the data pattern in the frame delimiter. A timing logic uses the plurality of re-timer values and the location of the marker in the data pattern in a timing calculation.
