Defined by the OPEN Alliance SIG, Automotive Ethernet, or IEEE 802.3bw (formerly BroadR-Reach), is an Ethernet physical layer standard designed for automotive connectivity applications, such as advanced safety features, comfort and infotainment features.
Automotive Ethernet enables multiple in-vehicle systems to simultaneously access information over an unshielded single twisted pair cable. The benefits for automotive manufacturers include reduced connectivity costs and cabling weight, with greater signal bandwidth.
To achieve greater signal bandwidth, Automotive Ethernet utilizes a full-duplex communication link over a twisted pair cable with simultaneous transmit and receive capabilities with PAM3 signaling. Full-duplex communication with PAM3 signaling can make visualization of Automotive Ethernet traffic and signal integrity testing very complex.
