Overview

SIST EN IEC 62228-7:2026 defines standardized test methods for the electromagnetic compatibility (EMC) evaluation of CXPI transceiver integrated circuits (ICs). Developed by the Slovenian Institute for Standardization (SIST), this standard is part of the broader IEC 62228 series, focusing on transceivers used in automotive applications. Part 7 addresses the specific requirements for CXPI (Clock Extension Peripheral Interface) transceivers, which play a critical role in modern in-vehicle networking, particularly for cost-sensitive, robust, and efficient communication.

The document provides detailed requirements for test configurations, measurement methods, test signals, and pass/fail criteria. It is designed to help manufacturers, test engineers, and automotive electronics developers ensure CXPI transceiver ICs meet international EMC requirements under realistic network operation and environmental conditions.

Key Topics

• Definition of CXPI Transceiver Types:
  The standard distinguishes between standard type-A, type-B, and embedded CXPI transceivers, based on their physical layer (PHY) implementations and functionalities.

• EMC Test Methods:
  The main focus areas include:

  • RF Emission: Measurement of radio-frequency interference generated by CXPI transceivers.
  • RF Immunity: Evaluation of the transceiver's resistance to external RF disturbances.
  • Impulse Immunity: Tests for resilience against electrical impulses.
  • Electrostatic Discharge (ESD) Immunity: Assessment of behavior under ESD conditions when unpowered.

• Test Setups and Conditions:
  Comprehensive guidance is provided for:

  • Test and operating conditions for both powered and unpowered states.
  • Preparation of test circuit boards and selection of required external components.
  • Minimum test network configurations simulating real application scenarios.

• Evaluation Criteria and Reporting:
  The standard specifies how to evaluate the EMC performance of CXPI transceivers and how to document test results to ensure repeatability and comparability.

Applications

• Automotive Electronics Design:
  As CXPI networks gain traction in automotive applications for body control modules, light controls, and other non-safety-critical systems, ensuring EMC-compliant CXPI transceiver ICs is essential to avoid unwanted interference with other vehicle electronics.

• IC Development and Qualification:
  Semiconductor manufacturers benefit from clear requirements when designing, validating, and certifying CXPI transceiver ICs for international markets.

• Third-party Testing and Certification:
  Test laboratories and organizations responsible for EMC certification utilize this standard to perform consistent and recognized EMC evaluations.

• System Integration:
  Automotive OEMs and Tier-1 suppliers use the standard for validating the EMC behavior of assembled electronic control units (ECUs) that incorporate CXPI transceivers.
