[0026] Referring to Figure 1 , it is structure schematic drawing of a preferable embodiment of the network card based on WX1820AL. In this preferable embodiment, according to the design of the utility model, a gigabit network card integrating four optical modules is made. One CPCIEx8 connector 11 is arranged on the side edge of the network card 10, and the corresponding curved pin guide pin seat 12 is arranged adjacent to the CPCIEx8 connector 11, so that the CPCIE interface can be fixed, and poor contact caused by network card shaking is prevented. Four optical modules 13 are arranged at the opposite side edge of the network card 10. In this preferable embodiment, the model of the curved pin guide pin seat 12 can adopt JC8.203.003, and the model of the CPCIEx8 connector 11 can adopt HMMH120P029A2B.

[0027] Referring to Figure 2 and Figure 3 , Figure 2 It is frame diagram of a preferable embodiment of the network card based on WX1820AL.Figure 3 The circuit block diagram of the preferred embodiment is described by taking the circuit block diagram of one of the two WX1820AL chips as an example. In the preferred embodiment, four SFP+ optical modules are integrated into a gigabit network card by using two WX1820AL (PCIE protocol to SFP+ protocol) chips. The preferred embodiment mainly comprises a CPCIEx8 connector, two WX1820AL chips, four optical modules, and a power module (POWER module). The CPCIEx8 connector is electrically connected to the two WX1820AL chips. The CPCIEx8 connector receives PCIE signals from external devices on one side and sends the received PCIE signals to the corresponding WX1820AL chips on the other side. The four optical modules are evenly divided into two groups, and each group of two optical modules is electrically connected to the corresponding same WX1820AL chip. Each WX1820AL chip converts the received PCIE signals into two SFP+ signals and sends them to the corresponding group of two optical modules. The power module is electrically connected to the two WX1820AL chips for power supply.

[0028] The gigabit network card is connected to the mainboard or other devices through the CPCIEx8 connector to receive PCIE signals from the mainboard or other devices, and then sends the received PCIE X8 signals to the WX1820AL network chip. The WX1820AL chip converts the PCIE signals into two groups of SFP+ signals and sends them to the corresponding optical modules. In the preferred embodiment, the optical module specifically uses an SFP+ connector. Therefore, the gigabit network card can have up to four SFP+ gigabit optical module interfaces.

[0029] Meanwhile, the network card is integrated with a power module for power supply to the WX1820AL chip. Because the CPCIE interface itself only has 12V and 3.3V power supply, the WX1820AL chip needs 3.3V, 1.8V, and 0.9V power supply. Therefore, in the design of the preferred embodiment, the power module converts the required power supply from the 12V power supply of the CPCIE interface. In the preferred embodiment, the power module can be designed based on power chips MPQ8633BGLE and MPQ8626GD-Z. The 1.8V and 0.9V power supplies are converted by the 12V power supply and additional power chips. The 0.9V power supply can be converted by MPQ8633BGLE, and the 1.8V power supply can be converted by MPQ8626GD-Z. The specific circuit of the power module can be designed according to the conventional design in the field, which is not described here.

[0030] In addition, according to the conventional design of the network card in the art, in the preferred embodiment, the network card is further provided with a reset module, a clock module, a UART socket, an SPI flash and the like, which will not be described herein.

[0031] Furthermore, referring to Figure 3 in the preferred embodiment, the WX1820AL chip and the optical module are electrically connected via a level conversion module, and the stray signal on the optical port needs to be additionally converted by the level conversion module, because the WX1820AL outputs a 1.8V level, and the optical port connector outputs a 3.3V level, so the conversion is needed. As for the SFP+ signal, it has its own protocol, so it does not need to be converted.

[0032] Referring to Figure 4 to Figure 8 which is a wiring diagram of the network card device in the preferred embodiment, the element marked NS in the drawing indicates that the element is not mounted, and the position is reserved. Among them, Figure 4 is a wiring diagram of the CPCIE x8 connector in the preferred embodiment; Figure 5 is a PCIE signal input wiring diagram of the WX1820AL chip in the preferred embodiment; Figure 6 is an SFP+ signal output wiring diagram of the WX1820AL chip in the preferred embodiment; Figure 7 is a wiring diagram of the level conversion module in the preferred embodiment; Figure 8 is a wiring diagram of the SFP+ optical module in the preferred embodiment.

[0033] Referring to Figure 4 which illustrates the wiring mode of the CPCIE x8 connector in the preferred embodiment, so that it can be used to connect the CPCIE socket on the mainboard or other equipment to receive the PCIE signal from the external equipment of the network card.

[0034] Referring to Figure 5 and Figure 6 the WX1820AL chip converts the PCIE signal to the SFP+ signal, which is a function provided by the chip itself, and the WX1820AL chip receives the PCIE signal input on one side and outputs the SFP+ signal on the other side, and each WX1820AL chip outputs two groups of signals.

[0035] Referring to Figure 7 which is a wiring diagram of the level conversion module in the preferred embodiment, in combination with Figure 3 it can be known that the stray signal on the optical port is converted by the level conversion module, and in the preferred embodiment, the level conversion module can be designed and manufactured based on the SGM4568YTS20G / TR chip.

[0036] Referring to Figure 8SFP+ signals from the WX1820AL chip are connected to the SFP+ connector, and SFP2 represents the optical connector, and JSFP2 represents the optical connector shell.
