Aviolinks® PXIe is a versatile and high-performance single Slot (3U) PXI Express module designed to support a wide range of avionic protocols. With its modular architecture, the device can be configured to meet the specific application requirements.

Key Features

• The device supports up to two modules, each capable of handling one or more of the following avionic protocols:
  • MIL-STD-1553 (M1553-1): provides 2 channel dual redundant communication per module with a single or multi-function operation with selectable direct or transformer coupling interface
  • ARINC-429 (A429-1): enables data transmission with 16 RX & 16 TX channels per module, ideal for various avionics applications
  • ARINC-825 (A825-1): supports bidirectional communication with 4 channels per module, offering versatility in system integration
  • Avionic Discrete (DISC-1): provides precise control of avionic discrete signals with 32 channels per module
• IRIG B time decoder: decodes IRIG B time signals up to 10 V peak to peak
  • Format: IRIG-B-122
  • Carrier wave: 1 KHz Amplitude modulated sine wave
  • Input amplitude: -5 V to 5 V (10 V peak to peak)
  • Modulation ratio: 3:1
• IRIG B time encoder: encodes SPI data from FPGA as 10 V peak to peak analog output.
  • Format: IRIG-B-122
  • Carrier wave: 1 KHz Amplitude modulated sine wave
  • Output amplitude: -5 V to 5 V (10 V peak to peak)
  • Modulation ratio: 3:1
• Discrete I/O: Offers 8 TTL level discrete input/output channels for digital control and monitoring.
• Conformity with PXI Express: enables data transfer and communication with a PXI Chassis. It supports PCIe Gen2 x1 link width (500 MB/s).
• Scope circuitry: features two channels for capturing differential analog signals. These two channels can be switched between external signals that are connected to the DSUB-78 connector or module signals that are attached to the carrier board.
  • Input signal range: -2.5 V to 2.5 V or -15 V to +15 V
  • Sampling frequency: 20 MHz
  • ADC output: 10 bits parallel
