3U OpenVPX Multifunction I/O Board

NAI's 68C3 is a rugged 3U OpenVPX multifunction I/O and communication control board with three function module slots, allowing for configurable I/O and communication tasks. Some modules feature FIFO data buffering for enhanced performance. With multiple DSPs, the motherboard delivers higher bandwidth and dedicated pre-processing control for each module. This innovative design eliminates the need for multiple specialized single-function boards, increasing packaging density, saving enclosure slots, and reducing power consumption.

The 68C3 low-power/high-performance board is ideal for rugged defense, commercial aerospace, and industrial applications. In a VPX chassis, it acquires sensor measurement data, controls simulation signals, and sends information to an external host processor via Gigabit Ethernet (Gig-E) or PCIe. The board's preexisting, fully-tested functions can be easily combined in unlimited ways, with each I/O function having dedicated processing to unburden the system's Single Board Computer (SBC) from unnecessary data management overhead.

  • Support for three independent, intelligent function modules
  • A variety of I/O and communication modules to choose from
  • VPX / OpenVPX (ANSI / VITA 46 & VITA 65) Slot Profile: SLT3-PER-1U-1F2U-14.3.3
  • Control via Gig-E, or PCIe interface
  • FIFO data buffering for A/D, D/A, S/D, and LVDT functions
  • Connections via front panel, rear panel, or both
  • Background Built-In-Test (BIT) (module dependent)
  • Software Support Kits (SSKs) and drivers available
  • VICTORY Interface Services (contact factory.)
  • Commercial and rugged models
  • Designed to meet ANSI / VITA 47 environmental requirements
  • Operating temperature: 0° C to 70° C commercial, -40° C to +85° C rugged


The 68C3 includes SSKs to support multiple operating systems. In addition, SSKs are supplied with source code and board-specific library I/O APIs to facilitate system integration.
