摘要： A first PHY may be coupled to a second PHY via a network link. The first PHY may transition from a role of timing master for the network link to a role of timing slave for the network link. During a first time interval subsequent to the transition, the PHYs may communicate half-duplex over the link while the first PHY synchronizes to a transmit clock of the second PHY. During a second time interval, the PHYs may communicate full-duplex while the second Ethernet PHY synchronizes to a transmit clock of the first PHY. Also during the second time interval, the first PHY may determine that the first PHY and the second PHY are synchronized. Subsequent to the determination, the PHYs may begin full-duplex communication of data on the network link.

摘要： Aspects of a method and system for physical-layer handshaking for timing role transition are provided. Prior to changing the timing role of a first Ethernet device, the first Ethernet device may communicate over an Ethernet link to a second Ethernet PHY utilizing a first set of one or more PCS code-groups. In response to a determination to change the timing role of the first Ethernet device, the first Ethernet device may communicate one or more IDLE symbols over the Ethernet link to the second Ethernet device. The IDLE symbol(s) may be generated utilizing a second set of one or more PCS code-groups. The first set of PCS code-group(s) may be mutually exclusive with the second set of PCS code-group(s). In response to detecting a received Ethernet physical layer symbol corresponding to the second set of PCS code-groups, the second Ethernet device may make a determination to change its timing role.

摘要： An Ethernet PHY may receive an indication from a local timing source that a local clock is suitable for propagation to a link partner. In response, a timer in the Ethernet PHY may be started. In instances that the Ethernet PHY receives, during a time period subsequent to starting the timer and before the timer reaches a predetermined value, an indication that the link partner is propagating a clock that is suitable for the Ethernet PHY to synchronize to, the Ethernet PHY may be configured as timing slave. In instances that the Ethernet PHY does not receive, during the time period subsequent to starting the timer and before the timer reaches a predetermined value, an indication that the link partner is propagating a clock that is suitable for the Ethernet PHY to synchronize to, Ethernet PHY may be configured as timing master upon the timer reaching the predetermined value.

摘要： 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.

摘要： A system and method for loop timing update of energy efficient physical layer devices using subset communication techniques. During a quiet period during which a subset of communication channels are transitioned from an active mode to a low-power mode, circuitry in the active channel can be designed to track, on behalf of the inactive channels, the phase drift due to the frequency offset. This tracking of the frequency estimation error would reduce the time required to perform a timing update for the communication channels when transitioning back to the active mode.

摘要： A system and method for dynamic power control for energy efficient physical layer communication devices. Energy-efficiency features are continually being developed to conserve energy in links between such energy-efficient devices. These energy-efficient devices interoperate with many legacy devices that have already been deployed. In these links, energy savings can be produced by having a local receiver enter an energy saving state based upon the receipt of standard IDLE signals.
