Disclosed are systems, methods, and devices for communicating a source of a 10SPE wake. Such a communication may be performed over a low-pin count hardware interface of a 10SPE physical layer (PHY) module having a split arrangement. A controller side of a 10SPE PHY may perform a local or remote 10SPE wake forward in response to a communicated source of a wake. Also disclosed is a digital interface for operatively coupling a PHY controller to PHY transceiver over a low-pin count connection, where the digital interface includes circuitry for checking the integrity of circuitry of the digital interface.

Low connection count interface wake source communication according to 10SPE local and remote wake and related systems, methods, and devices

A communication system, network, interface, and port architecture are provided for transporting data across a ring network. A network node operating as a first timing master generates a set of frames, each frame having a preamble, a data field and a time count field, which represents a portion of the time information associated with the set of frames. This time information may include counted time units, like seconds, or a number of generated and transmitted over the network. As the individual frames of a set of frames are generated and sent on the network, they pass other network nodes and are forwarded through the ring bus to the first timing master which receives at least a portion of the set it is still generating. This enables a received time count field to be compared with a transmitted time count field of the same set. If the fields are identical, there is no other timing master on the bus. If there is another timing master on the bus, the additional timing master would overwrite the contents of the time count field propagating through the network; therefore, the received time count field would not be equal to the time count field being transmitted by the first timing master.
