| 摘要 |
Embodiments of methods and apparatus for clock and data recovery are disclosed. In some embodiments, a method for recovering data from an input data stream of a device is disclosed, the method comprising synchronizing, during an initialization phase, a data clock (DCK) with an input data stream; synchronizing, during the initialization phase, an edge clock signal (ECK) with the input data stream based at least in part on a phase relationship between the ECK and the synchronized DCK; and sampling, during the initialization phase, a rising edge of the input data stream with the synchronized ECK to generate a transition level reference voltage. Additional variants and embodiments may also be disclosed and claimed.
