    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: Energy efficient Ethernet with asymmetric low power idle. Low power idle mode is typically leveraged when both direction of a link do not have data traffic to transmit. Such a requirement reduces the application of low power idle due to the frequent existence of data traffic in only one direction. An asymmetric low power idle mode enables reduction in power consumption and signal emissions even when one direction has data traffic to transmit.

    摘要: A physical layer (PHY) in a network device may provide self-adapting power reduction based on monitoring of activity associated with an interface between the PHY and remaining components of the network device. The power management operations of the PHY may then be configured and/or adjusted based on that monitoring. The PHY may comprise an Ethernet PHY, which may support energy efficient Ethernet (EEE) features. The monitored interface may comprise a Media Independent Interface (MII) based interface. In instances where the monitored activity comprises outbound traffic, outbound data received via the interface may be buffered when at least one subcomponent of the PHY that is operable to support transmission of the outbound traffic is unavailable due to the power management operations. The buffering may be configured to last to allow sufficient time to reactivate the at least one subcomponent.
