High-speed CAN networks prefer a linear topology. Avoid long "stubs" (branches off the main bus). Keep stub lengths under 0.3 meters to avoid signal degradation. Proper Termination Placement
To prevent signal reflections across the twisted-pair cable, the standard mandates a characteristic impedance of .
Specifies differential signal voltage levels, receiver thresholds, and loop-through delays. : A reputable European source for automotive standards
Many websites (such as GitCode repositories or "Wendang" uploads) offer links claiming a "free download" of the ISO 11898-2 PDF. However, these almost always involve copyright infringement. Besides being illegal, these scanned or leaked copies are often outdated, missing annexes, or contain corrupted images that could mislead your hardware design.

Explicitly defines requirements for higher data rates, which require stricter transceiver timing and electrical characteristics.
Outlines impedance and physical media guidelines to ensure signal integrity. Evolutionary Changes: ISO 11898-2 and CAN FD
Standardized for transmission rates up to 1 Megabit per second (Mbps) for classical CAN, and up to 2 Mbps, 5 Mbps, or higher for CAN FD (Flexible Data-rate).
ISO 11898-2 specifies the electrical characteristics and access parameters of the . It governs how data is translated into electrical signals and transmitted across the physical wires. Key Technical Specifications
Before downloading, ensure you select the correct version. In 2016, ISO consolidated the physical layer standards. The current version, , merged the older high-speed standard (ISO 11898-2:2003) with the low-power wakeup standard (ISO 11898-5) and the selective wakeup standard (ISO 11898-6) into a single, comprehensive document.
