ISO 11898-2

Road vehicles — Controller area network (CAN) — Part 2: High-speed physical medium attachment (PMA) sublayer

ISO 11898-2:2016 specifies the high-speed physical media attachment (HS-PMA) of the controller area network (CAN), a serial communication protocol that supports distributed real-time control and multiplexing for use within road vehicles. This includes HS-PMAs without and with low-power mode capability as well as with selective wake-up functionality. The physical media dependant sublayer is not in the scope of this document.
