Overview
IEC 62228-2:2016 is an International Electrotechnical Commission (IEC) standard focused on integrated circuits (ICs), specifically defining methods for evaluating electromagnetic compatibility (EMC) of Local Interconnect Network (LIN) transceiver ICs under network conditions. The standard provides comprehensive guidelines for test setups, measurement procedures, conditions, and criteria to ensure that LIN transceivers meet EMC requirements in actual applications.
This standard applies to both standalone LIN transceiver ICs and ICs with embedded LIN transceivers, encompassing:
- RF emission (electromagnetic disturbances)
- Immunity against RF disturbances
- Immunity against impulses
- Immunity against electrostatic discharges (ESD)
IEC 62228-2:2016 provides a structured, reproducible framework for assessing the EMC performance of LIN transceivers-critical components in the automotive and electronics industries.
Key Topics
IEC 62228-2:2016 covers several core areas for EMC evaluation of LIN transceivers:
- Test Configurations: Defines required network and board setups for both powered operation and unpowered conditions, ensuring real-world relevance and repeatability.
- Test Signals: Specifies format, amplitude, frequency, and timing of signals for routine operation and wake-up modes to simulate normal LIN network communication.
- Test Methods: Details procedures and parameters for:
- Emission of RF disturbances via direct coupling methods
- RF immunity testing using direct RF power injection (DPI)
- Impulse immunity using non-synchronous transient injection
- ESD immunity tests aligned with automotive industry practices
- Failure and Evaluation Criteria: Establishes pass/fail conditions for each EMC test, covering both powered “functional” and unpowered “passive” modes.
- Test Boards and Setups: Recommends soldered ICs on purpose-designed boards to minimize artifacts and ensure consistency.
Applications
IEC 62228-2:2016 is directly relevant for:
- Automotive Electronics: LIN transceivers are key in automotive communication networks. Compliance with this standard ensures reliable in-vehicle communication, data transmission, and robust response to EMC disturbances.
- IC Design and Validation: Semiconductor manufacturers, design engineers, and testing labs use IEC 62228-2 to verify new or existing LIN transceiver products meet EMC requirements before production release.
- Automotive System Integration: Integrators and OEMs rely on standard-compliant LIN transceivers for safer, more reliable vehicles. The standard supports evaluations under realistic network conditions, including the effects of network filtering.
- Conformance and Certification: Ensures global consistency in product testing, certification, and regulatory submission.
The standard is indispensable for professionals targeting robust EMC performance in LIN-based systems, offering a reliable benchmark for automotive communication ICs.
