Abstract

A device includes a transmitter coupled to a node, where the node is to couple to a wired link. The transmitter has a plurality of modes of operation including a calibration mode in which a range of communication data rates over the wired link is determined in accordance with a voltage margin corresponding to the wired link at a predetermined error rate. The range of communication data rates includes a maximum data rate, which can be a non-integer multiple of an initial data rate.

First claim

What is claimed is:

1. A device, comprising:
a node to couple to a wired link;
a receiver having an input coupled to the node for receiving a baseband signal that includes data transmitted by another device having a transmitter, the transmitter having an output coupled to the node; and
control logic to determine a performance metric, the performance metric comprising at least one of a timing margin corresponding to an error rate of the wired link and a voltage margin correspon…
