Method and device for link over-training |
摘要 |
A method and device of over training a connection is provided. Noise is intentionally supplied and added to a signal that is subjected to a link training operation. The link training operation is used to obtain a link between a source device and a receiving device. The device includes a noise source from which noise is obtained and added to a signal to aid in link over-training. |

1. A method of training a data link including:
obtaining signal noise by one of changing clock distribution methods associated with the data link; removing a first noise filter from cascaded phase-locked loops associated with the data link, increasing a level of a spread spectrum setting associated with the data link, and other noise sources related to routing, isolation, and tying to a power or ground rail; selectively and intentionally adding the obtained noise to a signal; and using the signal with the noise added thereto to train a data link. |
