Standard ECMA-369 MAC-PHY interface for ECMA-368

Summary

The document outlines various clauses and annexes related to the MAC-PHY interface. Clause 8 describes the interface signals, their directions, and functions. Clause 9 covers interface parameters and registers, providing a recommended mapping for PHY parameters, the register map, and timing for register access. Clause 10 defines frame formats for data exchanges over the interface. Clause 11 explains the Theory of Operation, detailing PHY states, transitions, reset and sleep protocols, frame timing, preamble control, and transmit/receive operations, including error cases. It concludes with the definition of CCA and Management interface protocols.

Annex A provides an Electrical Interface, while Annex B defines formats for two managed identifiers. The MAC-PHY signal interface, depicted in Figure 1, includes a Data Interface (8-bit data bus), a Control Interface (for operating state control and TX/RX status indication), a CCA Interface (for Clear Channel Assessment status), and a Management Interface (for accessing PHY registers). The Data Interface operation varies with the PHY state.
