摘要
采用脉冲电流注入(PCI)技术,对差分信号接收芯片(DS26C32ATM)的敏感阈值进行研究。试验结果表明,随着脉冲源电压的增大,传输线上的注入电流增大,差分信号接收芯片接口电路受到电磁脉冲干扰,发生损伤。对损伤芯片进行失效机理分析,定位故障。针对失效机理分析结果,对差分信号接收芯片进行加固防护研究。试验结果为后续差分芯片的抗电磁脉冲干扰的性能试验提供可靠依据。
The sensitivity threshold of differential signal receiving chip(DS26C32ATM)is studied by Pulse Current Injection(PCI)technology.The experimental results show that the injection current on transmission line increases with the increase of pulsed voltage,and the interface circuit of differential signal receiving chip is damaged by electromagnetic pulse interference.The failure mechanism of the damaged chip is analyzed and the fault position is located.Based on the analysis results of failure mechanism,the protection of differential signal receiving chip is studied.The experimental results provide a reliable basis for the experiment of anti-electromagnetic pulse interference.
