Backplane Data Bus
|Publication Date:||27 December 1993|
This document defines the electrical characteristics for a controlled impedance backplane bus for use with Integrated Modular Avionics (IMA). It defines the necessary characteristics of the bus that will ensure electrical compatibility at the interface between the avionics module and the IMA cabinet. ARINC Specification 659 defines the protocol, timing, bit rate and power requirements for the physical backplane. It defines the physical medium, physical layer and parts of the Media Access Control (MAC) sublayer referred to in the OSI Reference Model.
