Impact of PCB routing techniques on EMC radiated emission performance of high-speed interfaces
The design of modern electronic modules, packed with high speed digital interfaces, presents challenges in several areas. EMC and Signal-Integrity typically play a key role in defining the design direction, but PCB cost and manufacturing technologies also must be considered. Numerous publications focus on providing PCB design rules and guidelines for optimizing performance in a specific area, but little information addresses how to optimize design performance simultaneously in multiple areas. When such studies are available, often setups are too different for comparison purposes or test cases are idealized and do not represent solutions that can be practically implemented. This study examined how to manage existing time and cost pressures to identify a PCB routing strategy that is an optimal compromise between EMC and Signal-Integrity performance. This study used an 8-layer PCB to run a variety of test cases implementing different high speed signal routing techniques to provide equivalent Signal-Integrity performance. For example, we considered microstrip versus stripline routing, the presence of vias, using power and ground as references, and the presence of stitching vias when reference planes were changed. Each of these test cases was then evaluated from an EMC radiated emission performance standpoint using both CISPR-25 test results and CST simulation data.
