1. A vision system for a vehicle, said vision system comprising:

  • a camera disposed at a vehicle equipped with said vision system, wherein said camera, when disposed at the vehicle, has a field of view exterior of the vehicle, said camera capturing image data;

    a control comprising an image processor;

    a single coaxial cable connecting said camera with said control;

    wherein said single coaxial cable comprises a single core wire, an inner shielding layer and an outer shielding layer;

    wherein said inner shielding layer circumscribes said single core wire and said outer shielding layer circumscribes said inner shielding layer, and wherein said outer shielding layer is electrically isolated from said inner shielding layer and said inner shielding layer is electrically isolated from said single core wire;

    wherein said single coaxial cable carries (i) image data from said camera to said control, (ii) camera control data from said control to said camera and (iii) electrical voltage for powering said camera;

    wherein said image processor is operable to process image data captured by said camera and carried to said control via said single coaxial cable;

    wherein electrical voltage for powering said camera is carried by said inner and outer shielding layers, and wherein one of said inner and outer shielding layers is electrically connected to negative voltage or ground and the other of said inner and outer shielding layers is electrically connected to positive voltage;

    wherein said control receiving image data carried thereto via said single coaxial cable comprises a phase lock loop locking to a signal carrier frequency carried by said single coaxial cable; and

    wherein said camera is part of a plurality of cameras, and wherein respective coaxial cables connect said cameras with said control, and wherein said plurality of cameras and said control are part of a multi-camera surround view vision system of the vehicle.
