摘要：
In this paper, the problem of simultaneous switching noise (SSN) in the design of high-speed mixed-signal backplane is analyzed from the aspect of power integrity. How to suppress SSN of high-speed mixed-signal backplane becomes an important research direction at present. Based on the analysis of the traditional decoupling capacitor noise reduction method and the latest noise reduction principle of the electromagnetic band gap (EBG) structures, a novel type of EBG structures is proposed to suppress the noise on the printed circuit board (PCB). The simulation and measurement results show that the noise isolation depth reaches -40dB in the frequency band from 0.4 to 20GHz, which achieves the effect of ultra-wideband high isolation and meets the power and signal integrity requirements of high-speed mixed-signal backplane based on VPX(VITA 46). It provides an experimental reference for the application of the EBG structure on other high-speed mixed-signal backplane and other projects.
