Abstract:
1. A method performed by a network device, comprising: transitioning at least part of the network device from an active mode to an energy saving mode, the network device including a bus between a media access control device and a physical layer device, wherein during the energy saving mode, a first part of a media access control device interface coupled to the bus and a first part of a physical layer device interface coupled to the bus are powered down; and while in the energy saving mode, operating a second part of the media access control device interface and/or a second part of the physical layer device interface in a powered mode that enables generation of an adjusted clock signal transmitted across the bus, wherein the adjusted clock signal has a reduced duty cycle lower than a duty cycle of a clock signal generated when the at least part of the network device is in the active mode, the adjusted clock signal having multiple periodic cycles in a first time period having a reduced frequency and/or amplitude, and a second time period where no clock signal is generated.
