Abstract: A system may include one or more high-speed serial interfaces for moving data. A system may include a transmission unit configured to serially transmit data bits, and a receiving unit coupled to the transmission unit. The receiving unit may receive a stream of data bits from the transmission unit and establish an initial sample point. The receiving unit may then sample the bits at multiple offsets from the initial sample point, reestablishing the initial sample point between each offset. The receiving unit may also calculate bit error rates (BERs) for the samples taken at each sample point. Based on the BERs, the receiving unit may set a data sampling point for receiving a second stream of data bits from the transmitter unit. The receiving unit may limit the amount of time the data sampling point is used and recalculate the data sampling point when the amount of time has expired.
