Data transmission system for motor vehicle, has symmetric non inductive controller area network filter disposed after controller area network bus transceiver, and including two impedances that connect data signals to ground

摘要

The system has a controller area network (CAN) bus transceiver (1) placed after each transmitter and converting logic signals (TxD, RxD) into bus data signals (CANH, CANL). A symmetric non inductive CAN filter (2) is disposed after the bus transceiver. The filter has two impedances (Zy1, Zy2) that connect the lines (CANH, CANL) to the ground (GND) respectively.
