Unfortunately, PCB size and connector positions for the cables are usually pre-defined by mechanical constraints. Therefore, a certain minimum distance is required between the noise source, filter components, and connector. In close-field environments, the amplitude of the fields falls by 1 over distance squared (1/d 2). This filtering is only effective if no H- or E-fields from the noise source couple into the filter components or cables. To block this potential radiation path, filter circuitry is required at each cable connection point. Typically, noise from the DC/DC converter and other high-speed circuits radiates via connected cables that provide an effective antenna path. Integrating a DC/DC converter from the car board net into an automotive control unit and still fulfilling the EMC requirements of automotive OEMs is a difficult task.
