The VPX base standard defined in VITA 46 is a scalable backplane technology designed specifically for high speed, critical embedded systems.
The VITA 46 working group was first launched in 2003. At that time VMEbus systems (first introduced in 1981) were in wide use.
The VPX specification was extended in VITA 48 (VITA REDI, ruggedized enhanced design implementation) to support the increased operating power of high -density electronic modules by defining the mechanical design requirements to support enhanced cooling methods. VPX REDI also sets standards for the use of ESD covers on both sides of boards. WaveTherm provides engineered products & services that meet the VPX REDI (VITA 48) standard.
OpenVPX (VITA 65) is a system-level VPX specification designed to address interoperability between VPX boards and backplanes from multiple vendors. It was ratified in 2010.
Additional VITA standards have been ratified to support specific types of connectivity and other issues, and new VITA standards are still being actively worked on by their respective VITA
committees.
