Abstract: A primary device implementing the subject system of link establishment for single pair Ethernet may include at least one processor circuit. The at least one processor circuit may be configured to transmit a first synchronization sequence to a secondary device and to subsequently detect a second synchronization sequence, different than the first, transmitted by the secondary device. The synchronization sequences may be pseudo-noise sequences that have strong autocorrelation characteristics. The at least one processor circuit may be configured to wait a predetermined amount of time after completing the detection of the second synchronization sequence, and then may initiate a training stage. The training stage may include exchanging scrambler states of additive scramblers used by the primary and secondary devices. The at least one processor circuit may be configured to enter a data mode upon completion of training. In the data mode, data is forward error correction encoded and then scrambled.

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: Systems and methods for implementing an Energy-Efficient Ethernet (EEE) communication are provided. In some aspects, a method includes identifying an EEE signal configured to be communicated via a first set of wires. The method also includes processing the EEE signal such that the processed EEE signal is configured to be communicated via a second set of wires. The second set of wires including fewer wires than the first set of wires. The method also includes communicating the processed EEE signal via the second set of wires.
