Overview
IEC 62228-6:2022 is an international standard published by the International Electrotechnical Commission (IEC) that defines test and measurement methods for electromagnetic compatibility (EMC) evaluation of PSI5 transceiver integrated circuits (ICs). Specifically targeting Peripheral Sensor Interface 5 (PSI5) transceivers, this standard addresses both standalone satellite ICs, such as sensors, and ICs with embedded PSI5 transceivers, including electronic control unit (ECU) ICs.
This standard ensures that ICs comply with rigorous EMC criteria by defining test configurations, operating conditions, signal parameters, failure criteria, and measuring techniques. It covers key EMC aspects including emission of radio frequency (RF) disturbances, immunity to RF disturbances, impulse immunity, and electrostatic discharge (ESD) resistance.
