Abstract

In this paper, the effects of high power and frequency radiated RF interference on a high speed low voltage differential signaling (LVDS) system are investigated for electromagnetic susceptibility (EMS) of LVDS. The improvement method of EMS on LVDS is proposed by using common mode self-rejection (CMSR) flexible printed cable (FPC). External electromagnetic noise source such as an antenna in mobile device is constituted based on IEC 62132-3 bulk current injection (BCI) injection method. Bit error rate (BER) and eye opening results of LVDS system are used to judge the susceptibility of the system against to external radiated RF interference. The proposed method can improve BER and signal integrity (SI) of the high speed LVDS system.
