Abstract: A system for relaying communication for a PHY/data link level communication protocol may include a first device having a first and second transceiver, the first transceiver having a first protocol controller configured to detect a first bus condition and second transceiver having a second protocol controller configured to detect a second bus condition and a switching matrix coupled to the first and second transceiver and configured to operate in a relaying mode to enable: the first protocol controller to control a physical layer of the second transceiver and enables the second protocol controller to control a physical layer of the first transceiver, a physical layer of a first transmitter of the first transceiver to receive an output of a second receiver of the second transceiver, and the physical layer of a second transmitter of the second transceiver to receive an output of a first receiver of the first transceiver.

Abstract: A method of determining a phase misalignment between a first signal generated from a first signal path and a second signal generated from a second signal path may include obtaining multiple samples of the first signal proximate to when the first signal crosses zero wherein the first signal can be approximated as linear; obtaining multiple samples of the second signal proximate to when the second signal crosses zero wherein the first signal can be approximated as linear; based on the multiple samples of the first signal, approximating a first time at which the first signal crosses zero; based on the multiple samples of the second signal, approximating a second time at which the second signal crosses zero; and determining the phase misalignment between the first signal and the second signal based on a difference between the first time and the second time.
