The demand for high speed data transmission between electronics systems in modern vehicles has experienced a dramatic increase over the past years. The current generation of infotainment and ADAS systems already requires high data rates that are projected to grow even further in the future, fueled by trends like the upcoming introduction of connected and autonomous vehicles.
Automotive ethernet based on the BroadR-Reach technology is a promising candidate to become the standard high speed interface in vehicles. The current implementation offers a data rate of 100 Mbit/s over a single unshielded twisted pair cable, with plans to further increase it to 1000 Mbit/s. Unshielded twisted cables are lightweight and cost effective, however this comes at the cost of reduced EMC performance. The high data rates and the cable layout can pose significant challenges on designers of automotive electronics.
This webinar will present simulations of EMC related aspects of the automotive ethernet: the effect of the PCB layout on the emission from an automotive ethernet channel, crosstalk from the automotive ethernet channel to other cables inside one harness, and susceptibility of the channel based on the BCI testing method.
Andreas Barchanski received an MSc in physics in 2003 and a PhD in numerical EM in 2007 from the Technical University Darmstadt. He has joined CST’s HQ in Darmstadt in 2007 as an application engineer. Since 2012 he is Market Development Manager for EMC. Besides EMC, his main interest lies in simulation of various electronic systems ranging from high speed digital to power electronics. He has authored over 50 scientific papers, journal articles and presentations on numerical EM and its application.
