Description

A kind of pcie_x8 interface extended equipment

Technical field

The utility model relates to computer peripheral accessories field more particularly to a kind of pcie_x8 interface extended equipment.

Background technique

With growing steadily for electric automatization industry, many computer peripheral accessories are designed with pcie interface.Due to onboard Pcie card slot, which limits pcie equipment, can only be inserted in the enterprising enforcement use of mainboard, therefore for needing the pcie equipment of frequent plug It says and is not easy to operate, seriously affect the efficiency of plug interface.In addition, existing pcie extend line length can only within 30cm, Haves the shortcomings that extended line apart from inadequate when host and pcie equipment hypertelorism.And too long extended line will lead to signal mistake Problem true and that connection is unstable, influences reading of the mainboard to pcie equipment, mainboard can not read pcie equipment.

Therefore, the prior art is defective, needs to improve.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of pcie_x8 interface extended equipment, are having While effect extends pcie interface, guarantee the quality and stability of data-signal.

The technical solution of the utility model is as follows: a kind of pcie_x8 interface extended equipment, comprising: connect with computer main board Host side, the equipment end of external pcie equipment and the connection host side and equipment end two connecting lines, the host End include: host side power module, the pcie_x8 golden finger being connect with computer main board and the host side power module, with The host end signal trunk module and the host side of the pcie_x8 golden finger and host side power module connection The host side data input module of signal trunk module connection and the host end data being connect with the pcie_x8 golden finger Output module, the equipment end include: equipment end power module, connect with pcie equipment and the equipment end power module Pcie_x8 slot, the equipment end signal trunk module being connect with the pcie_x8 slot and the equipment end power module, It the equipment end data input module that is connect with the equipment end signal trunk module and is connect with the pcie_x8 slot Equipment end data outputting module.

Further, the host end signal trunk module and equipment end signal trunk module are all made of chip DS80PCI810。

Further, the host side data input module, host side data outputting module, equipment end data input mould Block and equipment end data outputting module use sff-8643 interface, and the connecting line uses sff-8643_5MX2 high speed number According to line.

Further, length L≤5m of the connecting line.

Further, the host side power module and equipment end power module are separately connected a power socket, two power sockets It is connected by power supply line.

Using the above scheme, the utility model can be by the length of pcie interface extended to 5m.Meanwhile in pcie application When operation, chip DS80PCI810 retains the characteristic of transmitting signal, so that host end signal trunk module and equipment end Signal trunk module can be negotiated to emit equalizer coefficients.The transparent management of this link negotiation agreement, helps to realize system Grade interoperability, and shorten delay in maximum guarantees data-signal quality of data-signal and steady in extension wire It is qualitative.

Specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

Referring to Fig. 1, the utility model provides a kind of pcie_x8 interface extended equipment, comprising: connect with computer main board Two connecting lines of host side, the equipment end of external pcie equipment and the connection host side and equipment end.

Fig. 2 to Fig. 7 is please referred to, the host side includes: host side power module and computer main board and the host side The pcie_x8 golden finger of power module connection, the master being connect with the pcie_x8 golden finger and the host side power module Generator terminal signal trunk module, the host side data input module being connect with the host end signal trunk module and with it is described The host side data outputting module of pcie_x8 golden finger connection.

Fig. 8 to Figure 13 is please referred to, the equipment end includes: equipment end power module and pcie equipment and the equipment The pcie_x8 slot of end power module connection, the equipment being connect with the pcie_x8 slot and the equipment end power module End signal trunk module, the equipment end data input module being connect with the equipment end signal trunk module and with it is described The equipment end data outputting module of pcie_x8 slot connection.Host side is used to be inserted on the pcie interface of computer main board, equipment end For connecting external pcie equipment, and host side and equipment end signal are connected to by connecting line.

The host end signal trunk module and equipment end signal trunk module are all made of chip DS80PCI810.In pcie When being run in, chip DS80PCI810 retain transmitting signal characteristic so that host end signal trunk module and Equipment end signal trunk module can be negotiated to emit equalizer coefficients.The transparent management of this link negotiation agreement, facilitates reality Existing system-level interoperability, and shorten delay in maximum, the distorted signals problem in remote transmission is effectively treated.

The host side data input module, host side data outputting module, equipment end data input module and equipment End data output module uses sff-8643 interface, and the connecting line uses sff-8643_5MX2 high speed data lines.Pass through Sff-8643_5MX2 high speed data lines are connected host side and are carried out data transmission with equipment end, ensure that transmission matter to greatest extent Amount.Length L≤5m of the connecting line.
