Abstract
An automotive Ethernet physical-layer (PHY) transceiver includes an Analog Front End (AFE) and a digital processor. The AFE is coupled via a full-duplex Ethernet link to a peer transceiver. The AFE is configured to receive from the peer transceiver, over the full-duplex Ethernet link, an analog Ethernet signal conveying data symbols, at a reception data rate that is lower than a transmission data rate used in transmitting data from the PHY transceiver to the peer transceiver, the Ethernet signal being modulated by a spreading sequence having a Spreading Factor including a ratio between a spreading chip-rate and the reception data rate, and to convert the received analog Ethernet signal into a digital signal. The digital processor is configured to de-spread the digital signal using the spreading sequence to recover the data symbols.
