Abstract: This application is directed to transferring data over a data link coupled between two electronic devices. The data link includes a retimer having a full data path and a bit level data path that are coupled in parallel. A first sequence of data packets is transferred via the bit level data path of the retimer. While transferring the first sequence of data packets, the data link detects initiation of an equalization procedure based on an initiation data packet in the first sequence of data packets. In accordance with detection of the initiation of the equalization procedure, the data link selects the full data path of the retimer for data transfer over the data link. During the equalization procedure, a second sequence of data packets immediately follows the first sequence of data packets, and is transferred via the full data path of the retimer.
