非平衡E1接口的EMC设计
EMC Design for Asymmetrical E1 Interface
摘要 EMC设计与接口设计紧密相关,很多产品的EMC指标都是由接口来实现的。E1接口广泛使用于欧洲和中国的通信产品中,通过对非平衡E1接口的EMC设计分析,提供了EMS设计和EMI设计的全套解决方案。经过试验验证,非平衡E1接口的EMC设计电路完全满足CE认证设备对外接口的静电放电抗扰度、电快速脉冲群抗扰度、浪涌抗扰度和传导发射的要求。

Abstract The EMC design for interface is very importance,hereby EMC performance of
equipment is to be accomplished rely on the interface’s EMC design。A detailed EMC
design is analyzed for asymmetrical E1 interface and that a full means to EMS and EMI
is to be provided in this paper。The designed asymmetrical E1 interfaces are completely
meet the CE authentication to ESD,EFT,surge and conducted emission。
