ARINC 429 Data BusARINC 429 defines the Air Transport Industry's standard for the transfer of digital data between avionics systems. This standard defines the Electrical Interface, Label and Address assignments, and Word Format Description.
Based on the ARINC 429 specification for serial communication, Device Engineering has developed a complete product line of line drivers that accept TTL/CMOS signals and put the data on the ARINC 429 avionics serial bus. These devices will also interface similar RZ type busses such as the 571 and 575. Many of the line drivers also support differential NRZ type serial busses such as the RS-422.
Incoming Data on the serial bus is in the dual rail format of the ARINC 429 and must be converted to signals that can be used in normal TTL/CMOS circuitry. Device Engineering offers these "line receivers" in a multitude of arrangements and packages.
The Transceiver circuit is used to interface a standard 16 bit wide micro computer bus with the ARINC serial data bus. The interface circuit includes a transmitter circuit, two identical but independent receiver circuits, and a programmable control register to select operating options.
