摘要： A method of sample offset adjustment comprises providing edges associated with an asynchronous input to a receiver (201 ). The waveform edges are densely distributed across an adjustment range. At least a portion of the adjustment range is scanned for samples to obtain an error count (202). A first sample position is fixed, and a second sample position is moved across at least a portion of the adjustment range. A threshold bit error rate ("BER") is located from the scanning (203). An amount and a direction of a sample offset at the threshold BER from a reference location is determined (204). Either the first sample position or the second sample position is adjusted responsive to the amount and the direction of the sample offset to at least reduce the sample offset (205).
