Abstract:
1. A method for selecting a sampling phase of a data stream, wherein the data stream has a variable data rate during a fixed time period, comprising the following steps: generating M section signals, having a same time interval, during the fixed time period of the data stream; generating N continuous clock phases, according to a rising edge of each of the section signals; selecting one of the N continuous clock phases in turn to provide a sample phase, wherein the continuous clock phases are corresponding to different section signals; performing a plurality of samplings on the data stream to generate a flag signal; repeating steps of the selecting and the sampling to generate N flag signals which are corresponding to different section signals, wherein the step of repeating steps of the selecting and the sampling further comprises: selecting a final sampling phase according to the N flag signals which are corresponding to the different section signals.
