: 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) iso 11898-2 pdf download
The transceiver actively drives CAN_H up to approximately 3.5V and CAN_L down to approximately 1.5V. This creates a minimum differential voltage ( Vdiffcap V sub d i f f end-sub ) of 1.5V to 2.0V. 2. Termination and Impedance

ISO - International Organization for Standardization Key Specifications of ISO 11898-2 This standard focuses on the Physical Media Attachment (PMA)
While ISO 11898-1 covers the data link layer, focuses entirely on the hardware interface—the transceiver and the medium. It is the standard used for the most common form of CAN, utilized extensively in the automotive industry (OBD-II diagnostics, engine control units) and industrial automation.
Q: What is the difference between ISO 11898-1 and ISO 11898-2? A: ISO 11898-1 covers the CAN bus protocol, while ISO 11898-2 covers the data link layer and physical layer of the CAN bus system.
Searching for a "free" ? You’re likely neck-deep in a project involving High-Speed CAN (Controller Area Network) physical layers. However, you can purchase and download the official
(the latest active version as of this writing) specifies the high-speed physical layer for CAN up to 1 Mbit/s. It describes:
The scope of ISO 11898-2 specifically covers the PMA sublayer, which sits at the lowest level of the CAN protocol stack. This sublayer handles the electrical signaling between the CAN controller (which manages the data link layer) and the physical medium (the twisted-pair wiring).
: The 2024 edition introduces support for SIC mode, which improves signal quality for high-speed CAN-FD (Flexible Data-Rate) networks. This annex spec enhances the standard's applicability for advanced automotive architectures.
