3U VPX embedded board serves multi-protocol avionics standards

A multi-channel, multi-protocol embedded board has been added to the VadaTech family. The VPX339 is a 3U VPX board which uses the latest Mil-Std-1553 technology, says the company.

It is based on Data Device Corporation’s (DDC) BU-67118 multi-channel, multi-protocol avionics product and uses what is claimed to be the world’s most advanced Mil-Std-1553 technology.

The module is low power, with high mean time between failure (MTBF). It has up to four dual redundant Mil-Std-1553 channels and features a bus controller disable for remote terminal-only applications and a transmit inhibit feature for mechanical transfer-only applications. There is also transmit inhibit for ARINC 429 Rx-only applications.

Other features are IRIG-106 Chapter 10 MIL-STD-1553 MT (mechanical transfer) and full line rate on all channels simultaneously.

The VPX339 has programmable ARINC 429 speed, up to two programmable Tx/Rx ARINC 717 channels, up to two CAN bus 2.0/ARINC 825 channels and up to eight programmable RS-232/422/485 channels.

There is asynchronous communications on all channels and synchronous communication on up to two channels. In addition there are up to 10 avionics/digital discrete I/O, a 48bit per 100 nanoseconds time stamp and IRIG-B input.

The VPX339 module can output Mil-Std-1553A/B, IRIG106, ARINC 429, CAN bus/ARINC 825 channels, discrete I/O, ARINC-717, advises VadaTech.

There is also an onboard DMA engine to reduce the CPU utilisation.

The inclusion of IRIG-106 Chapter 10, Tx inhibit, and ARINC 717 make the VPX339 particularly suitable for flight data recorders. The module can be used for a wide selection of equipment, including mission computers, displays and line replaceable units (LRUs) in aircraft cargo, digital data recorders, radar systems/situational awareness, commercial aerospace, flyable avionics/unmanned aerial vehicles (UAVs), data loading and data monitors.

VadaTech provides embedded computing, ranging from board level products, chassis level platforms, to configurable application-ready systems. The company has a focus on AdvancedTCA, MicroTCA, VPX and PCIe and combines electrical, mechanical, software, and system level expertise to provide customised commercial or rugged computing solutions to meet the most complex customer requirements.

VadaTech also offers specialised products for VME, CompactPCI, and other architectures.

The company is a member of PICMG and VITA. Its headquarters, design and manufacturing facilities are in Henderson, NV, USA and the company has design, support and sales offices in Europe and Asia Pacific.
