ISO 11898-2 standard specifies the High-Speed Physical Medium Attachment (HS-PMA)

  • 2024 Revision: The latest version integrates CAN SIC (Signal Improvement Capability) transceivers, which improve signal integrity and allow for longer bus lengths or higher data rates in complex topologies.
  • Older Versions: Focused strictly on classical high-speed CAN transceivers.

Key Scope of the Standard:

  • Speed: Defines communication speeds up to 1 Mbit/s.
  • Topology: Describes the linear bus topology with two terminated ends.
  • Medium: Specifies the use of twisted pair copper wires.
  • Electrical Characteristics: Defines voltage levels, bus levels (dominant/recessive), and input/output circuits.

4. Connectors

While the standard does not enforce a specific connector shape, it references the pin assignments for the 9-pin D-Sub connector frequently used in industrial CANopen applications. iso 11898-2 pdf download

Understanding ISO 11898-2: The High-Speed CAN Physical Layer Standard
Guide to Accessing and Utilizing the Standard 2024 Revision: The latest version integrates CAN SIC

Implementing the ISO 11898-2 standard requires a thorough understanding of the CAN bus protocol and its requirements. Here are some steps to follow: Key Scope of the Standard:

ISO 11898-2 is the international standard for the High-Speed Medium Access Unit of the Controller Area Network (CAN) . It defines the Physical Layer requirements, ensuring that different devices (nodes) can communicate reliably over the same two-wire bus . ISO 11898-2 Official PDF & Documentation

Termination is Key: If you've ever wondered why you need those 120-ohm resistors at each end of a CAN bus, this standard is the reason. They prevent signal reflections that would otherwise turn your data into digital "noise." What’s Inside the Standard?

Another angle: sometimes parts of ISO standards are available for free preview. Does ISO 11898-2 have a preview available? Maybe a few pages? I should mention that, but not link to it directly if it's against the rules. Also, note that many organizations offer training or certification related to these standards, which might include summaries or course materials.
