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