Problems solved by technology

[0004] Due to the high data transmission rate and stable quality of the PCI Express interface, this interface is adopted by more and more users, but the types of PCI Express interfaces required by different users are often different. A variety of possible PCI Express expansion slot lines are designed on the new motherboard, but some PCI Express expansion slot users often do not use them, resulting in unnecessary waste

Embodiment Construction

[0014] Because the signals connected by the lines of a large number of pins are the same between various PCI Express expansion slots, only the signals connected by a few pins are different. The PCI Express expansion slot circuit of the present invention is aimed at various PCI Express expansion slots. According to this feature, a circuit that can adapt to different types of PCI Express expansion slots has been designed. This embodiment takes PCI Express X1 and PCI Express X16 as examples for illustration, and PCI Express X1 is used for network card expansion slots, and PCI Express X16 is used for network card expansion slots. Graphics expansion slot.

[0015] see figure 1 and figure 2 , which respectively show the circuit diagrams of PCI Express X1 and PCI Express X16 expansion slots.

[0016] figure 1 The pins of PCI Express X1 are shown. There are 18 pins B1-B18 at the left end of the expansion slot, and 18 pins A1-A18 at the right end. The definition of each pin and th...

Abstract

A PCI Express expansion slot circuit is used for on circuit board, optional set as different kinds of PCI Express expansion slot. Said expansion slot circuit includes longer first PCI Express expansion slot circuit set with several first leading pins, corresponding each leading pin respectively set one first connection terminal on circuit board, corresponding first leading pin set at least one second connection terminal used for one shorter second PCI express expansion slot.

Description

【Technical field】 [0001] The invention relates to a PCI Express (Peripheral Component Interconnection Express, peripheral component expansion interface) expansion slot circuit and a design method thereof. 【Background technique】 [0002] PCI Express is a new generation of bus interface. Compared with PCI, this bus interface has realized the change of transmission mode from parallel to serial. PCI Express adopts point-to-point serial connection mode. Compared with PCI and earlier computer bus Sharing the parallel architecture, PCI Express allows each device to establish an independent data transmission channel without requesting bandwidth from the entire system, thereby increasing the data transmission rate. The serial connection method adopted by PCI Express can greatly reduce the signal interference and electromagnetic interference between cables, and compared with the parallel connection method, the number of transmission cables is also reduced, which can save space.
