Problems solved by technology

[0004] At present, in general personal computers, in response to the consideration of the production cost of the mainboard and the internal space of the personal computer, most of the mainboards only have one or two PCI-Express slots, so the PCI-Express slots that users can connect and use -The number of peripheral devices related to the Express interface is also limited, which has become a fly in the ointment

Embodiment Construction

[0015] The main technical feature of the PCI-Express multi-mode expansion card of the present invention is that in the connection interface regulated by the PCI-Express standard, in addition to the pins used to transmit the PCI-Express signal, additional built-in USB2.0 connection pin. Therefore, on the PCI-Express multimode expansion card of the present invention, in addition to being provided with the expansion port conforming to the PCI-Express pin position, the USB2. Extend out and form another expansion port. In this way, the PCI-Express multimode expansion card of the present invention can expand and connect two peripheral devices (one using the PCI-Express communication protocol and the other using the USB2. 0 communication protocol) to achieve the function of multi-mode expansion.

[0016] In order to describe the PCI-Express multimode expansion card proposed by the present invention more clearly, the following will list the embodiment to describe in detail the PCI-E...

Abstract

PCI-Express expansion card in multiple modes includes following parts: a PCI-Express interface port is in use for plugged to PCI-Express slot on main board; a PCI-Express expansion port; a USB expansion port; and jumper circuit connected between the PCI-Express interface port and two expansion ports. The PCI-Express expansion port can expand connecting a peripheral device in PCI-Express interface, and the USB expansion port can expand connecting a peripheral device in USB interface. In single PCI-Express slot setup on main board, one PCI-Express multiple modes expansion card can expand connecting two peripheral devices in different interfaces so as to reach expansion function in multiple modes.

Description

technical field [0001] The present invention relates to a PCI card and its communication device, in particular to a PCI-Express slot that can be inserted into a motherboard, and the PCI-Express slot is provided with an expansion link to a PCI-Express slot. A multi-mode expansion card for an Express interface peripheral device and a USB interface peripheral device and a communication device with the expansion card. Background technique [0002] In the past, PCI (Peripheral Component Interface) in personal computers was used to provide a transmission interface specification for connecting different functional devices, such as: VGA display card (Video Graphics Array; VGA), sound card, network card, data card , Image capture card, TV card, SCSI card, and 1394 expansion card, etc. Among them, the PCI peripheral devices need to share and use the total bandwidth of the PCI, so when there are more PCI peripheral devices connected, the bandwidth available for each device will be les...
