Purpose.

This document specifies the physical layer requirements for a Carrier Sense Multiple Access/Collision Resolution (CSMA/CR) data link which operates on a dual wire medium to communicate among Electronic Control Units (ECU) on road vehicles at normal transmission rates of:

• High Speed Bus 500 kbits/s

• Medium Speed Bus 95.24 kbits/s and 125 kbits/s

This document is to be referenced by the particular Component Technical Specification (CTS) which describes any given ECU in which the dual wire data link controller and physical layer interface is located. The performance of the data link layer and physical layer is specified in this document. ECU environmental and other requirements shall be provided in the CTS. Functional as well as parameter requirements in this document generally apply over the applicable operating conditions and aging. This includes, for example, operating ambient temperature, operating supply voltage and age drift over component lifetime unless otherwise noted.

The intended audience includes, but is not limited to, ECU suppliers, component release engineers, platform system engineers and semiconductor manufacturers of Controller Area Network (CAN) controller and CAN transceiver Integrated Circuits (IC).
