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.
