Ethernet over a single unshielded twisted pair (UTP) copper cable coupled with power over data lines (PoDL) is gaining momentum for automotive networking, as evidenced by the recent adoption of BroadR-Reach as the IEEE802.3bw (100BASE-T1) standard and the drafting of the IEEE802.3bp (1000BASE-T1) and IEEE802.3bu (PoDL) standards [1]. BroadR-Reach has won out for its superb electromagnetic compatibility (EMC) performance - a major challenge for adapting Ethernet to automotive environments [2]. Ethernet over plastic optical fiber, as specified by IEEE802.3bv [1], appears to be an EMC solution, but a separate medium is required to deliver power to networked sensors (such as cameras). Shielded pairs are not a good choice either, due to weight/size constraints and reliability concerns about shield grounding. This paper describes an analog front-end (AFE) that tackles the EMC problems and enables a 100BASE-T1 automotive product in 28nm CMOS.
