ISO 11992-1:2019 - Std. & Spec

Scope: 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.
