Abstract

Modern automotive electronic products with highspeed digital interfaces pose design challenges in the areas of signal integrity (SI) and electromagnetic compatibility (EMC). On one hand, the manufacturer must comply with legal and industry specific EMC requirements and on the other hand, the product is expected to function seamlessly over all environmental conditions and process tolerances. Numerous guidelines have been published on how to optimize the design performance in these two areas (EMC & SI) but few address the impact one can have on the other. This paper examines the impact several SI compliant routing patterns have on EMC emissions performance.

时钟网路由对汽车电子模块电磁兼容发射性能的影响
具有高速数字接口的现代汽车电子产品在信号完整性(SI)和电磁兼容性(EMC)方面提出了设计挑战。一方面,制造商必须遵守法律和行业特定的EMC要求,另一方面,产品应在所有环境条件和工艺公差下无缝运行。关于如何优化这两个领域(EMC和SI)的设计性能,已经发布了许多指导方针,但很少涉及其中一个可能对另一个产生的影响。本文研究了几种符合SI的路由模式对EMC发射性能的影响。
