Abstract
An automotive Ethernet physical-layer (PHY) transceiver includes an analog Front End (FE) and a digital processor. The FE is configured to receive an analog Ethernet signal over a physical Ethernet link while the Ethernet PHY transceiver is operating in a vehicle, and to convert the received analog Ethernet signal into a digital signal. The digital processor is configured to hold one or more noise profiles that characterize respective predefined noise types of noise signals that are expected to corrupt the received analog Ethernet signal, to classify an actual noise signal present in the digital signal into one of the noise types, using the noise profiles, and in response to deciding that the actual noise signal matches a given noise type among the predefined noise types, to apply a noise mitigation operation selected responsively to the given noise type.
