The shielding effect of a multi-cable harness as function of IC output termination impedance

Abstract

Integrated circuits for automotive applications must not violate certain limits for maximum electromagnetic emissions. One of many standardized compliance tests is the CISPR 25 ALSE test, where the radiated emission from a straight cable harness attached to a device is evaluated. For devices with multiple outputs this harness may contain multiple cables. It is critical to understand, that non-operated cables have a certain shielding effect, which is a function of their termination impedance. The radiated emission originating from a harness consisting of multiple cables will, in some cases, be drastically lower than that of a single wire. By applying fundamental electrostatic relations this paper demonstrates how to estimate the deviation by simple calculations. The analytical results are compared to measurements and 3D EM simulation.
