CompactPCI and PXI Bus Interfaces

CompactPCI bus interfaces and PXI bus interfaces are rugged, high-performance computer components that connect to system devices that use CompactPCI (cPCI), a high-performance standard based upon peripheral component interconnect (PCI) technology, and PCI eXtensions for instrumentation (PXI). CompactPCI interfaces are plug-in computer cards that function as system controllers. PXI bus interfaces provide programming control and are typically used in high-speed applications such as computer telephony and real-time data acquisition. Both Compact PCI interfaces and PXI bus interfaces use form factors popularized by VersaModule Eurocard (VME). Devices with a 3U form factor are 100 mm x 160 mm and have one 96-pin DIN connector that plugs into the backplane. Devices with a 6U form factor are 233 mm x 160 mm and have two 96-pin DIN connectors.
