VITA (organization)
The VITA ( V MEBUS I nternational T rade A ssociation ) is a non-profit organization of vendors and users with a common market interest in modular, real-time embedded systems. VITA became known through the publication of the VMEbus specification in 1994.

Important standards
VME64x (VITA1.1)
Today, many of the standards are outdated and no longer used. While the classic VMEbus (VITA1) is no longer relevant, systems and backplanes with the expansion of VITA 1.1 (VME64x) are still used frequently. Thanks to the downward compatibility, older VME cards can still be used here.
Gigabit Ethernet on VME64x backplanes (VITA31.1)
A VITA31.1 backplane is based on a standard VME64x backplane and is only extended by a Gigabit Ethernet link (1000BASE-T). This leads to a standard PICMG 2.16 Gigabit Ethernet switch , which connects the links to one another and, if necessary, to the front panel via an RJ45 connector. The Gigabit Ethernet is implemented in a star topology . Optionally, two Ethernet switch slots can also be integrated into the backplane, creating a double-star topology. This means that each slot has two Gigabit Ethernet links that are redundant to one another.
VME Switched Serial Standard - VXS (VITA41.X)
A VITA41 backplane is basically also based on a VME64x backplane. However, the P0 connector differs from that of the VME64x backplane. Instead of the Hard Metric (HM) connector, a MultiGig connector is used, which is designed for differential pairs of LVDS transmission. This enables transmissions in the range of several Gb / s. The standard defines many high-speed protocols that can be transmitted over these connections. These protocols are InfiniBand and Serial Rapid IO as well as the specifications for protocol transmissions of Gigabit Ethernet, PCI Express , Aurora and 10 Gigabit Ethernet, which have only been available as drafts so far .
VPX (VITA46.X)
A VPX backplane is no longer compatible with VME64x backplanes due to the connectors. However, the sub-standard VITA46.1 defines how the signals of the VMEbus can be mapped to the MultiGig connectors of the VPX backplane. In this way, hybrid backplanes can be produced easily, which enable the inclusion of VME64x, VXS and VPX cards. The VPX backplanes allow the transmission of high-speed signals in all connector areas in order to increase the transmission bandwidth. With VPX there are also some drafts for mapping the protocols Serial Rapid IO, PCI Express, Gigabit Ethernet and Infiniband for transmission on the backplane.
