Detailed ways

The multifunctional PCIE IO adapter board described in the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

A multifunctional PCIE IO adapter board described in the utility model provides a function of a multifunctional PCIE IO interface, which is used for connecting a main board and various PCIE devices to a server; the adapter board is a rectangular PCB board, and the The adapter board is provided with several equipment ends, CLK BUFFER and main board end, connects the PCIE device through the adapter board of the equipment end, and a retimer chip (retimer chip) to prevent signal distortion is set on the equipment end Device), connected to the main board of the server through the adapter board at the main board end, the main board end is connected with the retimer chip and the device end through the CLK BUFFER, and the retimer chip and the device end are connected Interaction, and at the same time, the retimer chip communicates with the motherboard side through the PCIE bus.

Optimally, in order to prevent the impact on the current design of the mainboard side, an independent power supply device is provided for the retimer chip on the adapter board, and there is no need to specially add corresponding voltage wiring on the mainboard side.

Example:

The design content and advantages of the multifunctional PCIE IO adapter board described in the present invention will be described in detail below through an embodiment.

The multifunctional PCIE IO adapter board described in this embodiment, the device end on the adapter board is a PCIE card slot; the main board end on the adapter board is a golden finger. As shown in the accompanying drawing 1, three PCIE card slots 2, CLK BUFFER3 and gold fingers 5 for connecting to the main board of the server are arranged on the adapter plate of this embodiment, wherein the gold fingers 5 pass through the CLK BUFFER3 Connected to the PCIE card slot 2, three PCIE devices can be inserted on the adapter board through the three PCIE card slots, and considering that from the CPU end of the server motherboard to the device end of the PCIE device, it may be due to high-speed The wiring of the differential pair is too long to cause signal distortion.
