VME, VPX, and VXI Products Specifications on GlobalSpec

Help with VME, VPX, and VXI Products specifications:

Product Type


	Product Type:
	Your choices are...
	Controller / Processor		Controllers are special computers that are used to control the VME / VXI network. They can control the data transfer between devices in the network, the status of interrupts, IRQs, registers, triggers, etc. Also they are used to control instruments in the network for tests and analysis. Controllers are the most important single element in a VME / VXI system.
	Extender		Extenders are boards used to improve or extend the functions of the standard VME / VXI cards.
	Switches		Switches are used in industrial systems to connect test points or devices to instruments for the purpose of testing, measuring or monitoring the system.
	Bus Interfaces / Adapters		Bus interfaces or adapters allow the VME / VXI system to communicate with other devices or systems.
	Power Interface Boards (PIB)		Power Interface Boards (PIBs) are computer boards used for the power section of the backplane. They are used to facilitate pluggable power supplies, headers, and utility connectors.
	Load Boards		Load Boards are boards used to test the capabilities of system specifications and capabilities. For example, a load board can be used to test the cooling capabilities of a system by applying the load to the power supply and then creating the necessary heat to test chassis cooling.

Your choices are...

VMEbus

The original VMEbus specification (IEEE-1014-1987). Some features:

Asynchronous transfer
Addressing range between 16 and 32-bits
Data path widths: between 8 and 32-bits
Bandwidth: 40 MBps

VME64

VME64 is a mechanical and electrical superset of the original VMEbus specification (IEEE-1014-1987). Some new features:

Asynchronous transfer
Addressing range between 16 and 40-bits
Data path widths: between 8 and 64-bits
Bandwidth: 80 MBps

VME64x

The VME64 Extensions (VME64x) specifications were adopted in 1997 by the VITA (VMEbus International Trade Association) Standards Organization (VSO). This new standard adds new capabilities to the VME64 bus:

A new 160-pin connector family
3.3 V power supply pins
Bandwidth: up to 160 MBps
Injector / ejector locking handles
Live insertion (hot-swap capability)

VME160

VME160 is a version of the VME320 standard. The VME320 can transfer data from 320 MBps to over 500 MBps. The VME160 is the 160 MBps version.

VME320

VME320, a new modified VMEbus architecture, was developed in 1997 by Arizona Digital, Inc. Some features:

Allows synchronous data transmission
Bandwidth range: from 320 MBps to over 500 MBps
Also comes in 160 MBps version

VPX

VPX (aka VITA 46) is an ANSI standard based on the VME bus with support for switched fabric using a high speed connector.

VXI^TMCompliant

VXIT^M (VMEbus eXtensions for Instrumentation) is a platform trademarked by National Instruments and a Consortium of other companies in order to define a multivendor instrument-on-a-card standard for industrial applications. The VXIbus specifications combine the VMEbus with the popular GPIB to create a modular instrumentation platform to meet the needs of instrumentation applications.

Form Factor:

Card format is given in terms of (height x length). The height is expressed in units of 'U', and the length in mm (millimeters). The most popular heights are:

3U = 100mm
6U = 233mm
9U = 360mm (Not part of the VMEbus specifications)

The VMEbus specifications recognize two types of cards: A single height board, also known simply as a 3U card, is 100mm x 160mm with one 96 pin DIN connector (the P1 connector) on the rear that plugs into the backplane. A double height board, also known as a 6U card, is 233mm x 160mm and may have a second 96 pin DIN connector (the P2 connector). There are 9U boards in existence but they are not part of the VMEbus specification. For VXI systems the cards are referenced by assigning a letter to the card: Size A, Size B, Size C, etc. VME systems reference the card by naming the height and the length: 3U x 160mm, 6U x 340mm, etc. The front edge (width) of a typical board is 20mm wide and may incorporate connectors, indicator lights and switches. (See table at the end of this help module).

Your choices are...

Size B cards have a height of 233 mm (6U) and a length of 160 mm.

6U x 340 mm (Size C)

Size C cards have a height of 233 mm (6U) and a length of 340 mm.

9U x 340 mm (Size D)

Size D cards have a height of 360 mm (9U) and a length of 340 mm.

9U x 400 mm

Cards have a height of 360 mm and a length of 400 mm.
