Adapter card for PCI (peripheral component interconnect ) Express X8 to CPCI (compact peripheral component interconnect ) Express X8

Abstract

The invention relates to an adapter card for PCI (peripheral component interconnect ) Express X8 to CPCI (compact peripheral component interconnect ) Express X8. The adapter card comprises an impedance control circuit board, an adapting circuit board, a PCI Express X8 interface, a CPCI Express X8 signal socket, a CPCI Express X8 power supply socket, a double row socket, a curved needle double row plug, a connecting block and a baffle, wherein the upper edge of the impedance control circuit board is crimped with the CPCI Express X8 signal socket and the adapting circuit board; the lower edge is provided with the PCI Express X8 interface; the curved needle double row plug is arranged in an inclined left middle part of the impedance control circuit board; the CPCI Express X8 power supply socket and the curved needle double row plug are installed on the adapting circuit board; the connecting block is used for vertically fixing the impedance control circuit board and the adapting circuit board trough screws; and the baffle is connected with the impedance control circuit board and a computer case through screws. With the adoption of the adapting card for PCI Express X8 to CPCI Express X8 provided by the invention, the quality and function of signals in the PCI Express X8 and CPCI Express X8 are not affected, application of current PCI Express X8 slots is expanded, and the development difficulty and cost of a CPCI Express X8 interface card is greatly reduced; and the adapting card is simple in structure and convenient in use.

Description

technical field [0001] The invention relates to an adapter card from a PCI Express X8 bus interface to a CPCI Express X8 bus interface, which is used for converting a PCI Express X8 slot in a commercial and industrial console computer into a CPCI Express X8 conforming to the PICMG EXP.0R1.0 standard slot, so that the CPCI Express X8 interface card (expansion card) conforming to the PICMG EXP.0R1.0 standard can be applied, debugged and tested in the PCIExpress X8 slot. The invention belongs to the fields of computer communication, computer aided testing and automatic testing. Background technique [0002] PCIExpress 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 ...

AI Technical Summary

Problems solved by technology

However, due to the difference between CompactPCIExpress 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)
