Quick Tips for Automotive Ethernet Transmitter Compliance Test
应用文章
The automotive industry is growing faster, including the upgrading of ADAS/AD technology and the innovation of EE architecture. Now most architecture shifted from distributed system to centralized computing domain system or a zonal system, which aims to reduce the number of ECUs and cables. Multiple sensors can be interconnected, each transmitting raw, high-resolution data to the Zonal ECU. In this process, sensors may be consolidated into a single link to minimize cable weight and costs, which subsequently increases throughput demands. Such zonal architectures require high-speed communication links. However, simply increasing the speed presents significant technical challenges. Therefore, we need to comply with the IEEE 802.3 series of standards or Open Alliance TC series standards strictly to guarantee the reliability. For 100BASE-T1and 1000BASE-T1 transmitter test, we need to follow IEEE 802.3 series and Open Alliance TC8 standard, there are several test items for Automotive Ethernet Physical Layer Transmitter Compliance Test. Sometimes we fail the test using AE6910T/AE6920T solution, it’s hard to find the root cause and fix it. This article can provide some tips for you to improve the test results and finally pass them.
