This document is a recommended practice and intended to provide a minimum set of implementation requirements of the Clock Extension Peripheral Interface (CXPI) protocol. This document specifies the parameter requirements of the CXPI protocol. The CXPI protocol provides some selected features of the Controller Area Network (CAN) protocol implemented on a UART-based data link for mainly HMI (Human Machine Interface) of road vehicles electric systems.

This document covers the requirements for Ethernet PHY qualification. Requirements stated in this document will provide a minimum standard level of performance for the Ethernet PHY block in the IC to which all compatible Automotive PHYs shall be designed. No other features in the IC are tested or qualified as part of this recommended practice. This will assure robust serial data communication among all connected devices regardless of supplier.

The scope of this specification is to define the transfer layer and the consequences of the Controller Area Network (CAN) protocol on the surrounding layers.

The subject matter contained within this SAE Information Report is set forth by the Class A Task Force of the Vehicle Network for Multiplexing and Data Communications (Multiplex) Committee as information the network system designer should consider. The Task Force realizes that the information contained in this report may be somewhat controversial and a consensus throughout the industry does not exist at this time. The Task Force also intends that the analysis set forth in this document is for sharing information and encouraging debate on the benefits of utilizing a multiple network architecture.

THE CSC Bus components defined herein were developed to provide simple, yet reliable, communication between a host master module and its sensors and actuators. The scheme chosen provides the ability to communicate in both polling mode and direct addressing modes. Vehicle Architecture for Data Communication Standards Committee voted to cancel document - 7/19/2002 J2058 and J2106 Rationale Per Jack Volk, Vice Chairperson of Vehicle Architecture for Data Communication Standards Committee, document not being used. Information may be contained in other documents, (not necessarily SAE documents).

The Class A Task Force of the Vehicle Network for Multiplexing and Data Communications Subcommittee is providing information on sensors that could be applicable for a Class A Bus application. Sensors are generally defined as any device that inputs information onto the bus. Sensors can be an input controlled by the operator or an input that provides the feedback or status of a monitored vehicle function. Although there is a list of sensors provided, this list is not all-inclusive. This SAE Information Report is intended to help the network system engineer and is meant to stimulate the design thought process.

The Class A Task Force of the Vehicle Network for Multiplex and Data Communications Committee is publishing this SAE Information Report to provide insight into Class A Multiplexing. Multiplexed actuators are generally defined as devices which accept information from the multiplexed bus. A multiplexed actuator can be an output device controlled by the operator or an intelligent controller. A Multiplex actuator can also be a display device that reports the status of a monitored vehicle function. This document is intended to help the network system engineers and is meant to stimulate the design thought process. A list of multiplexed actuator examples is provided in Appendix A, Figure A1. Many other examples can be it identified.

This SAE Recommended Practice defines the information contained in the header and data fields of non-diagnostic messages for automotive serial communications based on SAE J1850 Class B networks. This document describes and specifies the header fields, data fields, field sizes, scaling, representations, and data positions used within messages. The general structure of a SAE J1850 message frame without in-frame response is shown in Figure 1. The structure of a SAE J1850 message with in-frame response is shown in Figure 2. Figures 1 and 2 also show the scope of frame fields defined by this document for non-diagnostic messages. Refer to SAE J1979 for specifications of emissions related diagnostic message header and data fields. Refer to SAE J2190 for the definition of other diagnostic data fields. The description of the network interface hardware, basic protocol definition, electrical specifications, and the CRC byte is given in SAE J1850.
