标准范围

本文档描述了11992系列中指定的两个基于CAN的网络接口的数据链路层（DLL）和物理层（PHY）。DLL子条款包括:-DLL协议实体要求；-DLL设备接口要求；和-DLL网络系统要求。通常，物理信令子层在CAN协议控制器中实现。物理介质连接子层通常在CAN收发器或系统基芯片（SBC）中实现。可选地，它还可以包括额外的保护电路。媒体相关子层包括连接器和布线。物理信号（PS）子条款包括:-PS实体要求；-PS设备接口要求；和-PS网络系统要求。物理介质附件（PMA）子条款包括:-PMA协议实体要求；和-PMA设备接口要求。物理介质相关（PMD）子条款包括:-PMD实体要求；-PMD设备接口要求；和-PMD网络系统要求。

This document describes the data link layer (DLL) and physical layer (PHY) for the two CAN-based network interfaces specified in the 11992-series.The DLL sub-clauses are composed of:— DLL protocol entity requirements;— DLL device interface requirements; and— DLL network system requirements.Normally, the physical signalling sub-layer is implemented in the CAN protocol controller. The physical medium attachment sub-layer is normally implemented in the CAN transceiver or the System Base Chip (SBC). Optionally, it can comprise also additional protection circuitry. The media-dependent sub-layer comprises the connectors and the cabling.The physical signalling (PS) sub-clauses are composed of:— PS entity requirements;— PS device interface requirements; and— PS network system requirements.The physical medium attachment (PMA) sub-clauses are composed of:— PMA protocol entity requirements; and— PMA device interface requirements.The physical medium dependent (PMD) sub-clauses are composed of:— PMD entity requirements;— PMD device interface requirements; and— PMD network system requirements.
