Abstract

A Physical Layer (PHY) device, for use in an Ethernet network in a vehicle, includes a link interface and a transceiver. The link interface is configured to connect to a full-duplex Ethernet link. The transceiver is configured to communicate over the full-duplex Ethernet link in a first direction using a High-Data-Rate (HDR) signal having a first data rate, and to communicate over the full-duplex Ethernet link in a second direction, opposite to the first direction, using a Low-Data-Rate (LDR) signal having a second data rate, lower than the first data rate. A frequency spectrum of the LDR signal is contained within a frequency spectrum of the HDR signal.
