EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 62228-7 testing. This part of IEC EN 62228 specifies test and measurement methods for EMC evaluation of CXPI transceiver ICs under network conditions. It defines test configurations, test conditions, test signals, failure criteria, test procedures, test setups, and test boards.
This specification applies to standard CXPI transceiver ICs and ICs with an embedded CXPI transceiver and covers:
The purpose of this standard is to evaluate the EMC performance of CXPI transceiver ICs under minimum network application conditions. CXPI Transceiver ICs are generally classified into three types.
Overview of PHY substrates follows ISO 20794-4. The standard type-A includes a CXPI transceiver IC containing the PS sublayer and the PMA sublayer. The standard type B includes only the PMA substrate. Embedded type includes a microcontroller or ASSP functionality in addition to the functions of Standard type-A. The PMA sublayer transmits and receives communication data on the bus line in PWM signal format. The PS sublayer has clock generation functionality, encoding and decoding of CXPI frames, and bitwise collision resolution logic. The microcontroller or ASSP transmits and receives the communication data in NRZ signal format according to the specifications of the application.
