Card cage for an electronic control unit having signal-processing components and high-speed digital components coupled to a common ground plane

A card cage for an electronic control unit, comprising:

• a common ground plane;
• signal-processing components, the signal-processing components including at least one of an analog component and a digital component, the signal-processing components being combined into modules, wherein the signal-processing components of each module have at least one shared function, and wherein the signal-processing components of each module are connected to the common ground plane via a first single connection point of a plurality of first shared connection points;
• high-speed digital components, each of the high-speed digital components being individually electroconductively connected via a direct path to the common ground plane;
• and
• a voltage-supply plane having at least one voltage-supply line and at least one conductive planar section,
• wherein the first single connection point is one of a single via and a plurality of interconnected vias which are situated substantially close to one another,
• wherein each of the signal-processing components of a first one of the modules is conductively connected to a corresponding second shared connection point which is connected to the at least one voltage-supply line of the at least one voltage-supply plane, and
• wherein the high-speed digital components are individually conductively connected to the at least one conductive planar section of the at least one voltage-supply plane.
