Adapter card for converting PCI Express X2 into CPCI Express X2

Abstract

An adapter card for converting PCI Express X2 into CPCI Express X2 is used for converting a PCI Express X2 slot in a commercial and industrial console computer into a CPCI Express X2 slot meeting PICMG EXP.0R1.0 standards, so that a CPCI Express X2 interface card (expansion card) meeting the PICMG EXP.0R1.0 standards can be applied, debugged and tested in the PCI Express X2 slot in the common commercial and industrial console computer. The adapter card comprises an impedance control circuit board, a PCI Express X2 interface, a CPCI Express signal socket, a double-row-hole socket, an adapter circuit board, a connecting block, a bent pin double-row plug, a CPCI Express power socket and a baffle plate. The quality and the effect of signals in the PCI Express X2 and the CPCI Express X2 cannot be affected, development difficulty and cost of the CPCI Express X2 interface card are greatly reduced, and the adapter card is simple in structure and convenient to use.

Description

technical field [0001] The present invention relates to a kind of adapter card that is used for PCI Express X2 to CPCI Express X2, and it is used for converting the PCI Express2 slot in the computer into the CPCI Express X2 slot that conforms to PICMG EXP.0R1.0 standard, so that conforms to PICMG The CPCI Express X2 card of EXP.0R1.0 standard can be applied, debugged and tested in the PCI Express2 slot. The invention belongs to the fields of computer communication, computer aided testing and automatic testing. Background technique [0002] PCI Express is a new generation of computer serial bus, which replaces the traditional synchronous or asynchronous sequential logic bus interface with a protocol. It has high transmission rate, saves hardware resources, no crosstalk, no intersymbol interference, no signal offset, no DC bias and other outstanding features. Therefore, once launched, it has been widely valued and applied. At present, all kinds of commercial computers and i...

AI Technical Summary

Problems solved by technology

However, due to the difference between CompactPCI Express and PCI Express standard connectors and interface definitions, the CompactPCI Express interface board cannot be directly applied, debugged and tested in the PCI Express system (computer).

In other words, the current PCI Express system is not compatible with CompactPCI Express interface boards (expansion cards)
