The ARINC 429 Rx IP Core implements a receiver as specified in the ARINC Specification 429 Part 1-17.
This “Mark 33 Digital Information Transfer System (DITS)” specification defines how to transfer digital data between avionics systems elements. The transmission is done over a twisted and shielded pair of wires and bi-directional data flow is not permitted. An extra twisted and shielded pair of wires is used when data is required to flow both ways.
The ARINC 429 Rx Core has been developed to DAL A according to the DO-254 / ED-80 and is accompanied by a Certification Kit.
A radiation-hardened version with Triple Modular Redundancy (TMR) is also available.
Safe Core Devices provides two separate IP Cores, one for the ARINC 429 Rx Core and one for the ARINC 429 Tx Core. If the system needs to be capable of transmitting and receiving both cores can be instantiated in the target device.
The ARINC 429 Rx Core is already being used in one program: a civil large airplane program, as DAL A.
