OG exemplary drawing
 
1. A vehicular vision system, said vehicular vision system comprising:
a front camera disposed at a vehicle equipped with said vehicular vision system, said front camera viewing at least forward of the equipped vehicle;
said front camera comprising a CMOS imaging sensor operable to capture image data;
wherein said front camera is disposed at a windshield of the equipped vehicle and views forward through the windshield of the equipped vehicle;
an electronic control unit (ECU) disposed at the vehicle and comprising (i) a data processor and (ii) a DC power supply;
wherein image data captured by said front camera is conveyed from said front camera to the ECU via a 50 ohm coaxial cable;
wherein said front camera is in bidirectional communication with the ECU over the 50 ohm coaxial cable;
wherein the 50 ohm coaxial cable commonly carries (i) image data captured by said front camera to the ECU for processing at the data processor of the ECU and (ii) power from the DC power supply of the ECU to said front camera;
wherein said front camera comprises a data serializer and the ECU comprises a data deserializer, and wherein image data captured by said front camera is serialized at the data serializer and is conveyed to the ECU via the 50 ohm coaxial cable using a Gigabit Multimedia Serial Link (GMSL) protocol and is deserialized at the ECU by the data deserializer; and
wherein said vehicular vision system, responsive to processing at the data processor of the ECU of image data captured by said front camera and conveyed to the ECU via the 50 ohm coaxial cable, generates an output for a driving assist system of the equipped vehicle.
