    Abstract: Various embodiments relate to detecting collisions on a communication network. A method may include transmitting a first signal to a shared bus. The method may also include observing a second signal at the shared bus during the transmitting. Further, the method may include detecting a collision on the shared bus in response to an amplitude of the second signal being one of greater than a first threshold and less than a second threshold.

    Abstract: Systems, device, and methods related to estimating a Signal to Noise Ratio (SNR) of a signal are disclosed. A method of estimating an SNR includes setting a threshold of a comparator of a physical layer device to a first value, applying a signal to the comparator, and determining a first bit error number of an output of the comparator with the threshold set at the first value. The method also includes setting the threshold of the comparator to a second value that is different from the first value, applying the signal to the comparator, and determining a second bit error number of the output of the comparator with the threshold set at the second value. The method further includes determining an SNR of the signal based on the first bit error number and the second bit error number.

    Abstract: 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. Also disclosed is a PHY transceiver of a 10SPE PHY, where the transceiver includes a circuitry for controlling a starting polarity of frames.
