30.1 Single-Pair Automotive PHY Solutions from 10Mb/s to 10Gb/s and Beyond

Abstract

Car communication networks are rapidly evolving from a collection of sub-MHz control busses to a high-performance data network for connecting sensors, processors, and actuators to enable autonomous driving [1]. A plurality of high-bandwidth nodes like cameras, displays, radars, and wireless transceivers, demand a network architecture revision and drive the need-for-speed on individual links [1], [2]. Harsh automotive requirements on emissions, robustness, and reliability apply [3]. Size and weight of cables are critical factors too. These challenges inspired a new class of single-pair physical layer solutions, with 100Mb/s currently in production, 1Gb/s ramping up soon, and new standards for 2.5-10Gb/s in development.
