This document describes the data link layer (DLL) and physical layer for the two CAN-based network interfaces specified in this standard series. The DLL sub-clauses are composed of: – DLL protocol entity requirements, – DLL device interface requirements, – 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 may 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, – PS network system requirements. The physical medium attachment (PMA) sub-clauses are composed of: – PMA protocol entity requirements, – PMA device interface requirements. The physical medium dependent (PMD) sub-clauses are composed of: – PMD entity requirements, – PMD device interface requirements, – PMD network system requirements.
