Abstract
Aspects of a method and system for MAC and PHY synchronization for energy efficient networking are provided. In this regard, an interface that enables communication between a MAC controller and a PHY device may be configured to operate in an energy saving mode. While the interface is operating in an energy saving mode, synchronization between the MAC controller and the PHY device may be maintained by one or both of adjusting a clock generated for the interface and/or communicating dummy data via the interface. The clock may be adjusted by one or more of adjusting a frequency of the clock, adjusting an amplitude of the clock, and/or duty cycling the clock. The MAC controller and/or the PHY device may generate the dummy data. The PHY device and/or the MAC controller may discard the dummy data upon receiving the dummy data.
