Auto LANs Suppression of Noise in CANs Using CMCCs

The integration of electronic products into vehicles continues to grow at a fast pace. This trend includes the expansion and improvement of additional functions such as Advanced Driver Assistance Systems (ADAS). For the electrification of vehicles, automotive LANs that relay information between the various electronic devices inside the car play an essential role. Automotive LANs must not only offer high speeds in order to handle large volumes of information but also must offer high reliability, which is required for communication quality. Many interfaces tailored to these automotive devices are currently being used. It is in this context that Controller Area Networks (CANs) are becoming widely used as automotive LANs. Murata studies the electromagnetic noise issues in CANs and noise suppression components that offer a solution.
