ARINC 429 Transmitter

ARINC 429 Transmitter

The ARINC 429 TX is a soft IP for a single transmitter for serial communication in airborne applications. It has been developed in compliance with the requirements and objectives of the DO-254 DAL A. As a COTS IP, it can be instantiated as many times as required within a SoC to have multiple ARINC 429 transmitters. This IP has the following technical characteristics:

• User configurable data transmission bit rate: high speed or low speed
• 32-bit parallel user interface to write the frame to be transmitted
  • Frames are stored in a FIFO within the ARINC429-TX IP
  • FIFO size is configurable by the user (from 2 to 512 words)
• Parity bit calculation
• Frame encoding and transmission through data_high and data_low outputs according to the ARINC429 standard.
