A high frequency transmission cable is matched with a circuit board. The circuit board is equipped with a conducting portion and a grounding portion. The high frequency transmission cable includes a conducting wire, a first insulating layer surrounding the conducting wire, an aluminum foil layer and a second insulating layer. The aluminum foil layer surrounds the first insulating layer. An outer surface of the aluminum foil layer is a conducting surface. The second insulating layer surrounds the aluminum foil layer. The second insulating layer surrounds the conducting surface of the aluminum foil layer. The conducting wire is connected with the conducting portion. The conducting surface of the aluminum foil layer is connected with the grounding portion, so that the high frequency transmission cable has a grounding effect.

A vehicular vision system includes an ECU disposed at a vehicle and a front camera having a CMOS imaging sensor operable to capture image data. Image data captured by the imaging sensor of the front camera is conveyed from the front camera to the ECU via a single core coaxial cable. The front camera is in bidirectional communication with the ECU over the single core coaxial cable. The single core coaxial cable commonly carries (i) image data captured by the imaging sensor for processing at a data processor of the ECU and (ii) power from a DC power supply of the ECU to the front camera. Image data captured by the imaging sensor is serialized at a data serializer of the front camera and is transmitted to the ECU via the single core coaxial cable and is deserialized at the ECU by a data deserializer of the ECU.

Flexible cables may include multiple power, ground, and signal traces, and include EM interference suppression devices within the cable itself. Signal traces may be shielded by ground traces. The body of a cable may be divided into lateral portions through which different types of traces extend. One lateral side of a cable body may include a stack of power traces, while another lateral side of the cable body may include ground and signal traces. EBG patterns may be incorporated into ground traces. Capacitors may be positioned within the cable along its length, mounted between power and ground traces, for decoupling.
