Mx5 Series Avionics Interface Cards

XMC and PMC Avionics Interface Cards

Mx5 avionics interface cards enable embedded systems to communicate with, simulate, test, and monitor avionics equipment and systems. These rugged cards are available in both XMC and PMC standards with a choice of front or rear I/O configurations.

Mx5 high performance mezzanine cards efficiently manage fully loaded databuses with ease. On-board protocol processors handle all databus activity, freeing the host for application-specific processing. 64 MB ECC (error correction) memory provides generous data storage with a variety of buffering schemes.

High speed host interfaces are achieved with an x4 PCI Express lane with bus mastering on XMC versions and a 32/64-bit, 33/66/133 MHz PCI-X interface on PMC versions. All cards have extensive built-in test (PBIT, CBIT, IBIT).


The Mx5 includes an array of important features, including:

  • High I/O density:
    • MIL-STD-1553 (up to 8 dual-redundant channels, single or multi-function)
    • ARINC 429 (up to 18R4T)
    • ARINC 717 (up to 2R2T)
    • ARINC 708 (up to 2R2T)
    • 6 avionics discrete I/O
    • 2 In, 2 Out differential discretes
    • 4 virtual discretes
  • IRIG A/B PWM and AM
  • 48 bit time-tag
  • 64 MB ECC data memory
  • Extensive Built-in Test (BIT)
  • Extended temperature range
  • Conformal coating available

With so many features and so much flexibility, the Mx5 is your best solution in a wide variety of applications, such as:

  • Rugged deployed systems
  • Embedded test systems
  • High performance simulators
  • Demanding requirements
  • Mixed protocol systems
  • Avionics upgrades and retrofits
  • Databus health monitoring

With the Mx5, it has never been easier to standardise on one product line for all of your mezzanine card I/O needs.

Choose one or a combination of two or more protocols on a single card: MIL-STD-1553, ARINC 429, 717, and 708. Mx5 also includes numerous discrete I/O.
