ISO 11898-2 specifies the High-Speed Medium Dependent Interface (MDI) and part of the Physical Layer Signalling (PLS) for the CAN bus. It governs how data bits are electrically transmitted over the physical wires. Key Functions Defined by the Standard:
If you are currently working on a CAN-based system design or need to resolve an interoperability bug, purchasing the official is an invaluable investment that saves development time and guarantees engineering precision. If you are troubleshooting a design, let me know: What microcontroller or CAN transceiver you are using Your target data rate (Classical CAN or CAN FD) The physical length of your network
: The latest edition, released in March 2024, introduces support for CAN XL , pushing transceiver speeds to a maximum of 20 Mbit/s . It also adds Signal Improvement Capability (SIC) to manage signal ringing in complex topologies. Introduction to the Controller Area Network (CAN) (Rev. B)
