一、前言

随着汽车行业朝着电动趋势发展，摄像头、雷达、传感器等设备的设备使用场景越发广泛，对高速数据传输的需求也愈发依赖。而车载以太网具有低延迟、高带宽的特性可以满足高速、大容量数据传输，进一步支持高级智能驾驶功能的同时显著减小车身重量和整体线束成本，在现在及未来都会占据汽车通信总线的一席之地。

二、车载以太网降噪措施的必要性

1.以太网等差分信号传输中因各种原因共模电流会产生噪声，如IC内部原因、其他的走线或者空间耦合原因以及不同模式下的差共模转换产生的噪声。

2.在以太网传输时会因为双绞线和USB、HDMI等通信电缆的区别，会导致共模电流的磁场无法消除从而引起共模噪声能量变大。

3.高速差分信号存在偏斜（时间偏差）或振幅偏差，则两条线的信号均衡将被打破，从而产生共模噪声。

4.为了处理越来越复杂的车内电磁环境，通信链路的抗扰性能需要进一步的防护。基于以上原因，为了不影响车载以太网通信的正常通信以及不影响整体车内电磁环境，所以很有必要在车载以太网链路上增加滤波和防护措施，而在差分对上的滤波措施，最常见和最常用的就是共模滤波器，共模滤波器有不同的种类，磁芯、滤波频段各有差异，能应用在车载以太网上的共模则要求更严格。

三、车载以太网共模选型标准

为了保证车载以太网正常通信，并不是随便一颗信号线共模都可以使用在车载以太网通信链路上，所使用的共模必须遵循BS EN IEC 62228‑5:2021标准中给出的S参数标准，以保证CMC在滤除共模噪声的同时不会影响正常车载以太网的通信质量。如下图所示。

满足以上要求的共模电感需要在绕组、线圈、工艺上严格把控才有可能达到该标准上的要求，而韬略科技的车载以太网共模则都能满足该标准的要求，达到滤波要求的同时也保证了通信的正常。

四、总结

随着车载以太网的慢慢普及和使用，车载以太网链路上的滤波普及十分有必要，而作为滤波首选的共模滤波器，在选择时也应该更加谨慎和合理。

【经验】LVDS线路的EMC对策

LVDS即低压差分信号是目前最常见的差分传输系统，由于其高速传输能力、低功耗、低电压的特性优势，广泛应用于各种设备。与USB、HDMI等外部接口相比，LVDS多用于连接基板与屏的内部接口，同时在产品进行EMC测试时，LVDS也是经常遇到的一大问题点。韬略科技本篇介绍了一系列有关的对策。
