Abstract
A physical (PHY) circuit can include a Physical Medium Dependent (PMD) circuit, the PMD circuit having a receiver and a transmitter, a Physical Medium Attachment (PMA) circuit coupled to the PMD circuit, and a plurality of Physical Coding Sublayer (PCS) circuits coupled to the PMA circuit, wherein each PCS circuit is configured to implement a different communication protocol. The PHY circuit can also include an auto-negotiation circuit coupled to the PMD circuit, wherein the auto-negotiation circuit is configured to determine a selected communication protocol compatible with a link partner device from a plurality of communication protocols by configuring the receiver to operate at different data rates over time, the different data rates corresponding to different ones of the plurality of communication protocols.
