A Method to Quantify the Coupling between DVI and HDMI Connectors

Abstract

In a high-speed connector system, coupling to an adjacent cable-connector system is not uncommon. It is essential to understand and quantify this coupling path in order to mitigate the coupling. Though simulation based methods are widely used, such an approach is generally very time consuming and computationally resource hungry. A measurement based method for quantifying the EMI coupling path between a highspeed connector and an adjacent connector on the same board is presented. This is based on measured S-parameters for the mode conversion representing the coupling from the differential mode in one connector to the antenna mode current on the other connector-cable system. The method is validated on two test structures comparing estimated and measured radiated field emissions.
