Abstract
A sampling phase selection method for a data stream is provided, wherein the data stream has a variable data rate in a fixed time period. The method comprises generating a calibration signal, wherein the time interval of the calibration signal is longer than the fixed time period of the data stream, generating a first clock sequence and a subsequent second clock sequence, wherein the first and the second clock sequence are composed of a plurality of continuous clock phases and the number of the clock phases of the first clock sequence are the same as that of the clock phases of the second clock sequence, selecting one of the phases of the first and the second clock sequence, in turn, to provide a sampling phase, performing a plurality of samplings on the data stream to generate a flag signal, and selecting a final sampling phase according to the flag signals with different sampling phases.
