Analysis of new differential-mode source cable bundle crosstalk model based on FDTD

Abstract

The establishment of traditional cable bundle crosstalk model is based on the intra-system common mode source, without considering the crosstalk of cable bundles between different systems, and the cables are encouraged by differential-mode source. In this paper, a new differential-mode source cable bundle crosstalk method is proposed, which establishing a new three conductor transmission lines parasitic parameter circuit model, and disperses the new model to iterates the transmission line equations by one dimension Finite Difference time domain method. By calculating the new differential-mode cable bundle crosstalk model near and far end boundary conditions, it finally works out the result of the crosstalk voltage in time domain. The result shows the crosstalk of the victim cable which is located between differential-mode circuit is much larger than that located outside the differential-mode circuit.
