Low Electro Magnetic Interference (EMI) CXPI Transceiver for Automotive

BD41003FJ-C can reduce EMI (Electromagnetic Emission) noise of AM frequency band in comparison with BD41000AFJ-C. BD41003FJ-C is a transceiver for the CXPI (Clock Extension Peripheral Interface) communication. Switching between Master/Slave Mode can be done using the external pin (the MS pin). Low power consumption during standby (non-communication) using Power Saving function. Arbitration function stops transmitter output upon the detection of BUS data collision. Also Fail-safe function stops transmitter output upon the detection of under voltage or temperature abnormality.
