In addition, the "connection" in the following embodiments can include both direct connection between elements and indirect connection between an element and another element through other components.

[0049] It can be understood that “at least one” means one or more, “plurality” means two or more, and “at least a portion of an element” means a part or all of an element.

[0050] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise.

At the same time, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0051] In one embodiment, Figure 1 As shown, the present application provides a compatible circuit, which includes an interface unit 200, a network card module 100 and a compatible module 300; the compatible module 300 includes a first compatible resistor group 302 and a second compatible resistor group.

[0052] The first signal end of the interface unit 200 is connected to the transceiver interface of the network card module 100, and the second signal end of the interface unit 200 is connected to the indicator light control interface of the network card module 100 through the first compatible resistor group 302 and the partial resistor 304 in the second compatible resistor group, and the other partial resistor 306 in the second compatible resistor group is connected to the indicator light control pin of the network card module 100.

[0053] The network card type of the network card module 100 is determined by switching the loading status of the first compatible resistor group 302 and the second compatible resistor group. The network card type includes a first network card type and a second network card type.

[0054] Exemplarily, the transceiver interface of the network card module 100 corresponds to the transceiver interface of the installed network card chip. The network card module 100 can be used to install different types of network card chips with the same pin type. For example, the network card module 100 can be used to install network card chips such as RTL8111H or YT6801 of REALTEK. The interface unit 200 can be used to realize the function of network data transmission by connecting the transceiver interface of the network card chip. Optionally, the interface unit 200 can be an RJ45 interface.

[0055] Furthermore, the compatible module 300 can be used to control the working status of the corresponding network port light while being compatible with the operation of two different network card chips, for example, it can control the on and off frequency of the network port light.

[0056] It should be noted that part of the resistors of the first compatible resistor group 302 and the second compatible resistor group are associated with the working status of the network port lights corresponding to the network card chip; another part of the resistors 306 of the second compatible resistor group are used to match the driver program operation of the network card of the second network card type.

[0057] Specifically, when a network card corresponding to the first network card type needs to be installed, the first compatible resistor group 302 can be installed, while the second compatible resistor group is in the non-installed state; when a network card corresponding to the second network card type needs to be installed, the second compatible resistor group can be installed, while the first compatible resistor group 302 is in the non-installed state.

[0058] In one of the embodiments, the first network card type is an RTL8111H network card; the second network card type is an YT6801 network card.

[0059] It is understandable that although the pins of the YT6801 network card are consistent with those of REALTEK's RTL8111H network card, traditional computer motherboards still need to add and delete large amounts of original computer motherboard circuits when installing these two network cards, which greatly reduces the network card compatibility of computer motherboards and increases the component replacement cost of computer motherboards.

[0060] Specifically, when the compatible circuit of this embodiment is applied, when the RTL8111H network card needs to be installed, the first compatible resistor group 302 can be installed, while the second compatible resistor group is in a non-installed state; when the YT6801 network card needs to be installed, the second compatible resistor group can be installed, while the first compatible resistor group 302 is in a non-installed state.

[0061] In one embodiment, the network card chip of the network card module 100 is RTL8111H as an example, and the pins of RTL8111H are the same as the pins of the YT6801 network card. Figure 2 As shown, the indicator light control interface includes a first network port light control interface (i.e., LED0_R end) and a second network port light control interface (i.e., LED1 / EESK end); the indicator light control pin includes a first network port light control pin (i.e., LED0 pin of the network card chip in the figure), a second network port light control pin (i.e., LED1_GPO pin of the network card chip in the figure) and a third network port light control pin (i.e., LED2 pin of the network card chip in the figure); the network card module 100 also includes a first network port light control resistor R201, a second network port light control resistor R202, a third network port light control resistor R203 and a fourth network port light control resistor R204.

[0062] One end of the first network port light control resistor R201 is connected to the first network port light control pin, and the other end of the first network port light control resistor R201 is respectively connected to the other end of the second network port light control resistor R202 and the first network port light control interface.

[0063] One end of the second network port light control resistor R202 is respectively connected to the second network port light control pin and one end of the fourth network port light control resistor R204, and the other end of the second network port light control resistor R202 is also connected to the first network port light control interface.

[0064] One end of the third network port light control resistor R203 is connected to the third network port light control pin, and the other end of the third network port light control resistor R203 is respectively connected to the other end of the fourth network port light control resistor R204 and the second network port light control interface.

[0065] One end of the fourth network port light control resistor R204 is also connected to the second network port light control pin, and the other end of the fourth network port light control resistor R204 is also connected to the second network port light control interface.

[0066] The transceiver interface of the network card module 100 includes Figure 2 The MDI1_P0, MDI1_N0, MDI1_P1, MDI1_N1, MDI1_P2, MDI1_N2, MDI1_P3, and MDI1_N3 interfaces shown are used to connect to the first signal terminal of the interface unit 200 to perform network data transmission.

[0067] Specifically, the network card chip of the network card module 100 can connect some resistors of the second compatible resistor group through the first network port light control interface (LED0_R end) and the second network port light control interface (LED1 / EESK end), thereby realizing the function of controlling the working state of the network port light.

[0068] In one embodiment, illustratively, Figure 3 Taking the circuit part shown as an example, the interface unit 200 is an RJ45 interface; the first compatible resistor group 302 includes a first resistor R301, a second resistor R302, a third resistor R303 and a fourth resistor R304; some resistors of the second compatible resistor group are a fifth resistor R305, a sixth resistor R306, a seventh resistor R307 and an eighth resistor R308; the compatible module 300 also includes a fifth network port light control resistor R205, a sixth network port light control resistor R206, a seventh network port light control resistor R207 and an eighth network port light control resistor R208.

[0069] One end of the first resistor R301 is respectively connected to one end of the fifth resistor R305 and the first interface G_P of the second signal terminal, and the other end of the first resistor R301 is respectively connected to the other end of the second resistor R302 and the VCC power supply interface (ie, the “+VCC3 end” in the figure).

[0070] One end of the second resistor R302 is respectively connected to one end of the sixth resistor R306 and the fourth interface Y_P of the second signal end, and the other end of the second resistor R302 is respectively connected to the other end of the first resistor R301 and the VCC power supply interface.

[0071] One end of the third resistor R303 is respectively connected to the second interface G_N of the second signal end and one end of the eighth resistor R308, and the other end of the third resistor R303 is respectively connected to the other end of the fifth resistor R305, the other end of the fifth network port light control resistor R205 and the other end of the sixth network port light control resistor R206; the other end of the eighth resistor R308 is grounded.

[0072] One end of the fourth resistor R304 is respectively connected to the third interface Y_N of the second signal end and one end of the seventh resistor R307, the other end of the fourth resistor R304 is respectively connected to the other end of the sixth resistor R306, the other end of the seventh network port light control resistor R207 and the other end of the eighth network port light control resistor R208, and the other end of the seventh resistor R307 is grounded.

[0073] One end of the fifth resistor R305 is also connected to the first interface G_P of the second signal end, and the other end of the fifth resistor R305 is also connected to the other end of the fifth network port light control resistor R205 and the other end of the sixth network port light control resistor R206 respectively.

[0074] One end of the sixth resistor 306 is also connected to the fourth interface Y_P of the second signal end, and the other end of the sixth resistor 306 is also connected to the other end of the seventh network port light control resistor R207 and the other end of the eighth network port light control resistor R208 respectively.

[0075] The first network port light control interface (LED0_R end) is respectively connected to one end of the fifth network port light control resistor R205 and the other end of the seventh network port light control resistor R207;

[0076] The second network port light control interface (LED1 / EESK terminal) is respectively connected to one end of the sixth network port light control resistor R206 and one end of the eighth network port light control resistor R208.

[0077] Among them, each interface of the second signal end (i.e., the G_P, G_N, Y_N, and Y_P interfaces of the RJ45 in the figure) can be used to transmit the corresponding network port light control signal to the corresponding network port light, for example: the G_P (Green_Positive) interface can be associated with the positive pole of the green network port light, and the Y_N (Yellow_Negative) interface is associated with the negative pole of the yellow network port light. Further, when each interface of the second signal end transmits a "LINK" signal to the corresponding network port light, the corresponding network port light is always on; when each interface of the second signal end transmits an "Active" signal to the corresponding network port light, the corresponding network port light flashes.

[0078] In some examples, such as Figure 3 As shown, the interfaces of the first signal end of the interface unit 200 include TD1+, TD1-, TD2+, TD2-, TD3+, TD3-, TD4+, and TD4-. Further, the interfaces of the first signal end of the interface unit 200 are respectively connected to the transceiver interface (e.g. Figure 2 The following figure shows the MDI1_P0, MDI1_N0, MDI1_P1, MDI1_N1, MDI1_P2, MDI1_N2, MDI1_P3, MDI1_N3) connections to achieve network data transmission.

[0079] It can be understood that the VCC power supply interface (i.e. the "+VCC3 terminal" in the figure) can be used to power each network port light.

[0080] Optionally, the internal VCC interface of the interface unit 200 can also be connected to the VDD10 pin of the network card module 100 through a ninth resistor R309; wherein one end of the ninth resistor R309 is connected to the VDD10 pin of the network card module 100, and the other end is respectively connected to the pin of the internal VCC interface of the interface unit 200 and one end of the first capacitor C301, and the other end of the first capacitor C301 is grounded.

[0081] In one embodiment, if Figure 4 As shown, the network card chip of the network card module 100 is a YT6801 network card as an example; the other part of the resistors 306 are respectively a first driving resistor R401, a second driving resistor R402 and a third driving resistor R403.

[0082] One end of the first driving resistor R401 is connected to the first network port light control pin (i.e. Figure 2 The LED0 pin of the network card chip shown in the figure), the other end of the first driving resistor R401 is grounded.

[0083] One end of the second driving resistor R402 is connected to the second network port light control pin (i.e. Figure 2 The other end of the first driving resistor R401 is grounded.

[0084] One end of the third driving resistor R403 is connected to the third network port light control pin (i.e. Figure 2 The LED2 pin of the network card chip shown in the figure), the other end of the first driving resistor R401 is grounded.

[0085] The first driving resistor R401 , the second driving resistor R402 and the third driving resistor R403 are used to match a driver program corresponding to a network card of the second network card type.

[0086] Specifically, when a second network card type network card (such as a YT6801 network card) is required, the second compatible resistor group can be installed, while the first compatible resistor group 302 is in an uninstalled state, thereby ensuring the normal operation of the second network card type network card and its driver.

[0087] In one embodiment, if Figure 5 As shown, it also includes an electrostatic discharge protection module connected between the first signal terminal and the transceiver interface.

[0088] The electrostatic discharge protection module is used to provide electrostatic discharge protection for the network card module 100. Optionally, the electrostatic discharge protection module may include ESD 0524.

[0089] Specifically, the electrostatic discharge protection module is Figure 2 Take the ESD 0524 shown as an example: the pins on one side of the ESD 0524 are connected to the corresponding transceiver interface of the network card chip, and the corresponding pins on the other side are connected to the corresponding pins (or interfaces) of the first signal end of the interface unit 200, thereby achieving ESD protection. For example, if pin 5 of the ESD 0524 is connected to the MDI1_P0 of the network card chip, then pin 6 of the ESD 0524 corresponding to pin 5 is connected to the corresponding MDI1_P0 pin of the interface unit 200 (i.e., the TD1+ port of the RJ45).

[0090] In one possible implementation, Figure 6 As shown, the network card chip of the network card module 100 is RTL8111H or YT6801 as an example; the circuit also includes a clock reference module; the clock module includes a first reference resistor R601, a first reference capacitor, a second reference capacitor and a crystal oscillator unit.

[0091] Among them, one end of the first reference resistor R601 is respectively connected to the XTAL1A end of the network card chip of the network card module 100 (corresponding to the CKXTAL2 pin of the network card chip) and the first end of the crystal oscillator unit YL2, and the other end of the first reference resistor R601 is respectively connected to the third end of the crystal oscillator unit YL2, the XTAL2A end of the network card chip of the network card module 100 (corresponding to the CKXTAL1 pin of the network card chip) and one end of the first reference capacitor C601. One end of the first reference capacitor C601 is also connected to the third end of the crystal oscillator unit YL2, and the other end of the first reference capacitor C601 is grounded; one end of the second reference capacitor C602 is also connected to the first end of the crystal oscillator unit YL2 and one end of the first reference resistor R601, and the other end of the second reference capacitor C602 is grounded.

[0092] Specifically, the clock reference module can be used to provide a reference frequency for the network card. Optionally, the reference frequency can include 25 MHz.

[0093] In one possible implementation, Figure 7 As shown, the network card chip of the network card module 100 is RTL8111H or YT6801 as an example; the circuit also includes a digital circuit power supply module.

[0094] The digital circuit power supply module includes a first power supply inductor L701, a first power supply resistor R701, a first power supply capacitor C701, a second power supply capacitor C702, a third power supply capacitor C703, a fourth power supply capacitor C704, a fifth power supply capacitor C705, a sixth power supply capacitor C706, a seventh power supply capacitor C707 and an eighth power supply capacitor C708.

[0095] Among them, one end of the first power supply inductor L701 is respectively connected to the REGOUT port of the network card module 100 and one end of the eighth power supply capacitor C708, and the other end of the first power supply inductor L701 is respectively connected to one end of the first power supply capacitor C701, one end of the second power supply capacitor C702, one end of the third power supply capacitor C703, one end of the fourth power supply capacitor C704, one end of the fifth power supply capacitor C705, one end of the sixth power supply capacitor C706, one end of the seventh power supply capacitor C707 and the VDD10 end of the network card module 100.

[0096] The other end of the first power supply capacitor C701, the other end of the second power supply capacitor C702, the other end of the third power supply capacitor C703, the other end of the fourth power supply capacitor C704, the other end of the fifth power supply capacitor C705, the other end of the sixth power supply capacitor C706, the other end of the seventh power supply capacitor C707 and the other end of the eighth power supply capacitor C708 are grounded.

[0097] Furthermore, the first power supply inductor L701 may be replaced by the first power supply resistor R701, that is, the first power supply inductor L701 or the first power supply resistor R701 may be selected for loading. Figure 7 “CO-LAY” is used in FIG. 7 to represent the compatibility relationship between the first power supply inductor L701 and the first power supply resistor R701.

[0098] Specifically, the digital circuit power supply module makes the power supply of the network card chip more stable through the above circuit structure.

[0099] In one embodiment, the present application provides a compatibility method, which is applied to the compatible circuit described in any one of the embodiments of the first aspect above; the method includes:
