Organization: ISO
Publication Date: 1 May 2019
Status: active
Page Count: 32
ICS Code (Car informatics. On board computer systems): 43.040.15
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.
