Basic EMC Technology Advancement for C(3) Systems. Volume 3B. Computer Simulation of EMI Effects in a Differential Line Receiver

摘要

This paper discusses the computer simulation of sinusoidal interference in a National DS 55115 integrated circuit differential line receiver. The receiver is designed to sense differential signals (i.e., differences in the signals at the two terminals of the input port). Typically, the receiver is used in conjunction with the National DS 55114 integrated circuit differential line driver which provides differential output signals with high current capability for driving balanced lines such as twisted pairs. Attention in this effort is focused on the receiver, as opposed to the line driver, because the receiver is significantly more susceptible. Consequently, the susceptibility of the driver-receiver pair is determined by that of the receiver for most interference situations.
