摘要： Aspects of a method and system for interference cancellation substantially as shown in and/or described in connection with at least one of the figures, as set forth more completely in the claims. In this regard, a receiver may be operable to receive a differential signal via a differential channel, and to sense a common mode signal on the differential channel. A frequency range in which interference is present in the common mode signal may be determined. The differential signal and the common mode signal may be filtered to attenuate frequencies outside the determined frequency range. A phase and/or amplitude of the filtered common mode signal may be adjusted based on the filtered differential signal and the adjusted and filtered common mode signal may be subtracted from the received differential signal. The common mode signal may be sensed via a pair of resistors coupled to the differential channel.

摘要： Ethernet link partners coupled via an Ethernet link that comprises a plurality of channels are operable to transmit and receive at different maximum data rates on different channels. Based on link conditions, a link partner may negotiate a transmission rate and/or accept or reject a reception rate. Based on link conditions, a first link partner is configured to communicate in simplex mode at a first rate via at least one channel and receive in simplex mode at a second rate via at least one channel. The configured data rates are less than or equal to the respective maximum rates or a rate of zero. Link conditions comprise link load or utilization, current or past conditions, PER, BER and SNR. Power may be lowered for transmitters, receivers, near-end and/or far end cross talk cancellers, hybrids, echo cancellers and other components. Channels may be transitioned from duplex mode to simplex.

摘要： An Ethernet link may comprise one or more link partners that may be communicatively coupled via one or more silent channels. One or more circuits and/or parameters corresponding to silent channels may be retrained, refreshed and/or updated based on various triggers, for example, fixed times, periodic or aperiodic time intervals, random or pseudorandom timer, events, link statistics, physical conditions such as noise, temperature level, cable type and/or cable length, communication from a corresponding link partner and/or based on programming from, for example, a layer above the physical layer. The retraining, refreshing and/or parameter updating may occur for one or more of an echo canceller, a far-end crosstalk canceller and a near-end crosstalk canceller corresponding to the one or more silent channels. Subsequent to the retraining, refreshing and/or parameter updating, the one or more silent channels may be activated and/or may remain silent.

摘要： Aspects of a method and system for reducing transceiver power via a variable signal constellation are provided. In this regard, an Ethernet PHY device may receive one or more signals indicative of a current state of an Ethernet link to which the PHY device is coupled and/or indicative of resources, such as power, available to the PHY device. Accordingly, a number of points comprising a signal constellation utilized to communicate data via the Ethernet link may vary based on the one or more signals. A current state of the link may comprise a bit error rate, a packet error rate, and/or utilization, in terms of bandwidth for example, of the link. Aspects of the invention may enable controlling, at least in part, power consumption of the PHY device may altering the number of points comprising the signal constellation.

摘要： A system and method for using a link energy signal in physical layer devices (PHYs) having a silent channel/interface in energy efficient Ethernet (EEE). LPI modes in EEE suffer deficiencies in cable unplug detection due to the latency in refresh cycles. LPI modes in EEE also suffer from potential frequency drift, which leads to high bit error rate (BER) when coming out of LPI mode. A link energy signal transmitted during LPI modes enables real-time detection of cable unplug and the frequency lock to be maintained.

摘要： Aspects of a method and system for reducing transceiver power via a variable number of channels are provided. In this regard, utilization and/or availability of network and/or device resources may be determined and a configuration of channels utilized for transmitting data may be determined based on the determined utilization and/or availability of resources. Accordingly, the number of channels over which data is communicated may be altered based on determined thresholds for the utilization and/or availability of resources. Moreover, the configuration of channels utilized for communicating data may be dynamically altered by monitoring changes to the utilization and/or availability of resources. For example, the number of channels may be altered based on available bandwidth on one or more channels, based on capacity and/or available space of one or more buffers, and/or based on available power or desired power consumption of a transmitter.
