Abstract: According to an example embodiment, a communications receiver may include a variable gain amplifier (VGA) configured to amplify received signals, a VGA controller configured to control the VGA, a plurality of analog to digital converter (ADC) circuits coupled to an output of the VGA, wherein the plurality of ADC circuits are operational when the communications receiver is configured to process signals of a first communications protocol, and wherein only a subset of the ADC circuits are operational when the communications receiver is configured to process signals of a second communications protocol.

Abstract: A system, method and apparatus for multi-lane auto-negotiation over reduced-lane media. Auto-negotiation over an M-lane communication interface can be coordinated with the auto-negotiation over an N-lane communication interface, wherein M>N. A recursive-type auto-negotiation process would begin with the M-lane communication interface and be prevented from completing until the auto-negotiation process over the N-lane communication interface completes.
