Abstract: Aspects of a method and system for an extended range copper transceiver are provided. Reducing the communication rate provided by multi-rate physical (PHY) layer operations in an Ethernet transceiver may extend the range of the Ethernet transceiver over twisted-pair copper cabling from a standard connection length. The Ethernet transceiver may support up to 1 Gbps or up to 10 Gbps transmission rate over copper cabling. The multi-rate PHY layer architecture in the Ethernet transceiver may support signal-processing operations, such as echo cancellation and/or equalization, which may be applied to the reduced communication rate to enable range extension. The reduced communication rate may be achieved by reducing the symbol rate provided by the multi-rate PHY layer operations. Reducing the communication rate may also enable utilizing greater insertion loss cabling for a standard connection length.

Abstract: A programmable channel-swap crossbar switch for swapping signal flow from one channel to another within an Ethernet physical layer device (PHY) is presented. The crossbar switch includes two or more programmed multiplexers, each multiplexer configured to receive two or more input signals and to select which one of the input signals to pass to a programmed corresponding channel, such that a first, input signal associated with a first channel can be swapped to a second channel as operating conditions necessitate. The crossbar switch can be used for Ethernet communications with various communication speeds, such as 10BaseT, 100BaseT, and Gigabit communications. A crossbar switch can be used in both a transmit path and a receive path. Two crossbar switches may be used in a receive path in order to undo channel swapping for control signal processing. A method of channel-swapping in an Ethernet PHY communications system is also presented.

Abstract: Communication devices coupled via a communication link may comprise physical layer devices that may be operable to determine presence of a received signal and to mitigate noise in the signal prior to processing and/or validating the signal. Analog and/or digital signal processing may be utilized to process the signal and/or mitigate noise in the signal. Noise mitigation may comprise near-end crosstalk cancelling and/or echo cancelling and/or may utilize local transmit signal information. Subsequent to noise mitigation, samples of the noise reduced signal may be accumulated and/or an average signal strength and/or average signal power level may be determined. The average signal strength and/or average signal power level may be compared to one or more thresholds which may be configurable and/or programmable.

Abstract: Aspects of a method and system for extended range Ethernet link discovery signaling are provided. A local PHY may detect of one or more active twisted-pair wires in a remote PHY in extended range applications. The local PHY may determine whether to operate as a master or slave based on detected pairs. When operating as a master device, the local PHY may correct twisted-pair wire swap information received from the remote PHY before communicating an encoded link length value to the remote PHY. When operating as a slave device, the local PHY may transmit encoded twisted-pair wire swap information to the remote PHY before recovering a link length value communicated from the remote PHY. The local PHY may communicate supported operating modes based on the link length value to the remote PHY. Moreover, the local PHY may enable establishing a common full duplex operating mode with the remote PHY.
