control busses to a high-performance data network for connecting sensors, processors, and actuators to enable autonomous driving [1]. A plurality of highbandwidth 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. Figure 30.1.1 shows a typical domain-based network as used in today’s cars. Domains are separated for safety reasons, with a secure gateway for cross-domain connections. Data traffic within a domain cannot be hampered by other domains. However, this architecture has also disadvantages. Nodes of a domain are typically
