ANSI/VITA 1-1994 (S2021)	VME64	The VME64 standard establishes a framework for 8-, 16-, 32, and 64-bit parallel-bus computer architectures that can implement single and multiprocessor systems. This bus includes the four basic sub-buses: (1) data transfer bus, (2) priority interrupt bus, (3) arbitration bus, and (4) utility bus. The mechanical specifications of boards, backplanes, subracks, and enclosures are based on IEC 297 and IEEE 1101.1 specifications, also known as the Eurocard form factor.

ANSI/VITA 1.3-1997 (S2021)	VME64x 9U x 400mm Format	This standard is an extension of the ANSI/VITA 1-1994, VME64 Standard. It defines 9U x 400 mm boards, backplanes and subracks for use in application requiring large format printed circuit boards.	ANSI/VITA Stabilized Maintenance
ANSI/VITA 1.5-2003 (S2014)	VME 2eSST	An extension of the ANSI/VITA 1-1994, VME64 and ANSI/VITA1.1-1997, VME64x standards, it defines a transfer protocol, based upon source synchronous concepts that permit the VMEbus signalling to operate at rates to at least 320MB/s. The 2eSST protocol requires low skew between signals and monotonic rising and falling edges on the signals. To meet these requirements, limited length backplanes, special backplane topologies and/or enhanced transceivers are required.

The SCSA buses coexist with products compliant with ANSI/VITA 1-1994, VME64. SCSA at the physical level consists of two separate subbuses, a sixteen line TDM data transfer bus called the SCbus, and a serial, peer-to-peer communication link called the SCmessage bus. The primary purpose of the SCbus is to support the exchange of real time telephonic voice, facsimile, data, video and other media streams.

ANSI/VITA 48.8-2022	Mechanical Standard for VPX REDI Air Flow Through Cooling, 1.0 "to 1.5 "Pitches	This document describes an open standard for the design requirements for an air-flow-through cooled plug-in module having 3U and 6U form factors while retaining the VITA 46.0 connector layout. Unlike using cooling air impinged directly upon the components and circuit boards, this plug-in module uses a finned heat exchanger frame located within the central section of the assembly to top cool primary circuit board components as well as mezzanine board components. Both 3U and 6U standard form factors are offered using 3 defined pitch spacings, with options to have alternate air flow intake and exhaust paths. The plug-in modules of this standard exhibit a weight reduction and cost savings by eliminating both wedge retainer usage and module lever usage by way of using light weight jack screws for plug-in module insertion and extraction into a subrack chassis. The intention of this standard is to optimize SWAP-C (Size, Weight, Power, Cost). This revision of the standard updates the plug-in module in the following areas: tab dimensions, thickness, jackscrew, and additional screw. Also, the option for insertion/extraction levers has been removed.	ANSI/VITA Approved
