摘要
EMC设计与接口设计紧密相关,很多产品的EMC指标都是由合理的接口电路方案实现。通过对USB 3.0接口EMC和安规设计要求的详细分析,从静电防护、信号线EMI抑制、电源限流及稳压滤波等方面提供了USB 3.0接口的EMC和安规设计全套解决方案。经试验验证,设计方案完全符合CE认证等对USB接口的EMC和安全要求。
The EMC design is closely related to the interface design.The EMC performance of many products are implemented through a reasonable interface circuit scheme.Based on the detailed analysis of the EMC and security design requirements of the USB 3.0 interface,a complete set of EMC and security design solution for the USB 3.0 interface are provided in terms of static electricity protection,EMI suppression of the signal line,power current limiting and regulated voltage filter.The test result shows that the design fully meets the EMC and security requirements of the CE certification on the USB interface.
