Description

Technical Field

[0001] The present application relates to the field of electronic technology, and more particularly, to a network transceiver and a wake-up circuit. Background Art

[0002] Currently, many networked electronic devices, such as commercial signage, educational systems, televisions, all-in-one computers, industrial control systems, and commercial displays, often remain in standby mode when not in use. When powered on, these devices may remain in standby mode for extended periods, requiring quick wake-up upon user demand. Furthermore, these devices often require network control and operation, necessitating network wake-up functionality that allows them to be awakened from standby mode via network commands.

[0003] The relevant standards of some countries and regions have upper limits on the standby power consumption of electronic devices that support network wake-up functionality. In related technologies, electronic devices with network wake-up functionality in standby mode require their system-on-chip (SoC) to receive and analyze network data in real time in order to identify user-defined network wake-up requests. This SoC consumes relatively high power, so electronic devices using this technology consume relatively high power in standby mode and may not meet the upper power consumption limits set in the relevant standards.

[0004] In view of this, how to enable electronic devices to have a network wake-up function with low power consumption in standby mode is an issue that needs to be solved urgently. Summary of the Invention

[0053] The technical solution in this application will be described below with reference to the accompanying drawings.

[0054] In this application, the methods, situations, categories and divisions of the embodiments in each application embodiment are only for the convenience of description and should not constitute special limitations. The features of various methods, categories, situations and embodiments can be combined without contradiction.

[0055] It should be understood that the "first", "second" and "third" in the application embodiments are only for distinction and should not constitute any limitation to this application. The "multiple" in the application embodiments refers to two or more. The term "and / or" is used to describe the association relationship of associated objects, indicating that three relationships can exist; for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and subsequent associated objects are in an "or" relationship.

[0056] It should also be understood that in the various embodiments of the present application, the size of the serial number of each process does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0057] This application relates to electronic devices and network wake-up functionality in electronic devices. The electronic devices may be network-enabled devices that can be used in a variety of fields and scenarios. For example, the electronic devices may include commercial signage, educational systems, televisions, all-in-one computers, industrial control systems, commercial displays, electronic whiteboards, and other electronic products. This application does not limit the specific type of electronic device.

[0058] In addition, the network wake-up function involved in the present application can be to transmit network instructions to wake up the electronic device through the Ethernet communication method. The Ethernet communication method may include Ethernet protocol stack firmware compatible with the IEEE802.3 protocol, such as Internet Protocol (IP), Dynamic Host Configuration Protocol (DHCP), Address Resolution Protocol (ARP), Internet Control Message Protocol (ICMP), Internet Group Management Protocol (IGMP), User Datagram Protocol (UDP), Transmission Control Protocol (TCP), etc., or it can be through network technologies such as token ring, fiber distributed data interface (FDDI), asynchronous transfer mode (ATM) through routing relay to transmit network instructions to wake up the electronic device. The present application does not limit the specific type of network technology used by the electronic device. When the electronic device is in the standby state, the electronic device can enable the network wake-up function. In this case, the electronic device can detect the network instruction and enter the wake-up state or continue to maintain the standby state according to the instruction content.

[0059] Figure 1 This is the basic framework of an electronic device provided by the embodiment of the present application. Figure 1 As shown, the electronic device 100 includes a network interface 110, a network transceiver 120 and a control device 130. As an example, Figure 1 The network interface 110 shown can be a registered jack (RJ) 45 interface, the network transceiver 120 can be a network interface chip (shown as a CH392F chip in the figure), and the control device 130 can be a control chip in the electronic device 100 (shown as a SoC in the figure).

[0060] Optionally, the electronic device 100 may further include a power management unit (PMU) 140 for controlling the power supply of various components in the electronic device 100, for example, Figure 1The PMU 140 may be connected to the control device 130 and may be used to control the power supply of the control device 130 .

[0061] Based on the above solution, the CH392F can implement an RJ45 to Universal Asynchronous Receiver / Transmitter (UART) or Universal Serial Bus (USB) serial port integrated circuit and supports customized TCP / IP commands. However, the CH392F only supports wake-up interrupts when external network data changes at a specified IP address, and does not support custom commands to wake the device. If responding to custom commands, the SoC needs to monitor and analyze the CH392F data in real time. In this case, the device power consumption will usually approach or exceed 2W, which may exceed the relevant standards.

[0062] Therefore, based on Figure 1 The technical solution of the embodiment shown requires the control device 130 to receive and judge network instructions for the user-defined wake-up function, and the standby power consumption is relatively high.

[0063] Figure 2 This is the basic framework of another electronic device provided in the embodiment of the present application. Figure 2 As shown, the electronic device 200 includes a network interface 210, a network transceiver 220, a first control device 230 and a second control device 240. As an example, similar to Figure 1 , Figure 2 The network interface 210 shown may be an RJ45 interface, the network transceiver 220 may be a network interface chip (illustrated in the figure as a CH392F chip), the first control device 230 may be the first control chip in the electronic device 200 (illustrated in the figure as a SoC), and the second control device 240 may be the second control chip in the electronic device 200 (illustrated in the figure as a low-power microprocessor [microprogrammed control unit, MCU]). Optionally, the electronic device 200 may further include a PMU as a power management device 250, which has similar functions to the PMU in the electronic device 100 described above and will not be further described.

[0064] In this embodiment of the present application, a low-power MCU is added between the SoC and the Ethernet PHY (CH392F). When the machine is operating normally, the MCU acts as a bridge for Ethernet data conversion: it receives Ethernet data and sends it to the SoC, and sends data from the SoC to the external network. When the machine is in standby mode, the MCU maintains the network port data monitoring function. When it determines that a power-on command has been received, the MCU triggers the SoC / PMU power-on signal through the IO, thereby waking up the machine.

[0065] The above solution can meet customer needs, that is, to achieve network standby wake-up through customer-defined TCP / IP protocol instructions. However, it is necessary to add an additional low-power MCU to monitor network data when the machine is in standby mode. Therefore, it is necessary to add corresponding MCU circuits and MCU code writing and maintenance, which increases the complexity of the system.

[0066] In view of the deficiencies in the above-mentioned solutions, the embodiments of the present application provide an improved solution.

[0067] Figure 3 This is a circuit block diagram of a network transceiver provided in an embodiment of the present application. The network transceiver can be applied to an electronic device.

[0068] like Figure 3 As shown, the network transceiver 320 includes: a first port 321, a second port 322, and a processor 323. The first port 321 is connected to the network interface 310 in the electronic device and is used to receive network instructions sent by the network interface 310; the processor 323 is used to obtain a preset network wake-up condition, and when the electronic device is in a network standby state, determine whether the network instruction meets the network wake-up condition, and generate a wake-up instruction if the network instruction meets the network wake-up condition; the second port 322 is connected to the control device 330 or the power management device 340 in the electronic device and is used to send the wake-up instruction to the control device 330 or the power management device 340 to wake up the electronic device.

[0069] Optionally, in the embodiment of the present application, the network transceiver device 320 may be a network transceiver chip or a network interface chip, for example, a network transceiver chip. In some embodiments, the network transceiver device 320 may be the above-mentioned Figure 1 or Figure 2 The CH392F chip in the embodiment shown.

[0070] The first port 321 in the network transceiver 320 is used to connect to the network interface in the electronic device, and the network interface can be, for example, the network interface described above. Figure 1 or Figure 2 The RJ45 interface in the illustrated embodiment. Alternatively, in some alternative embodiments, the network interface may also be an RJ11 interface, a USB interface, a coaxial cable connector (Bayonet Neill-Concelman, BNC) interface, or other types of interfaces. The first port 321 may be used to receive network instructions, network data, or other network information sent by the network interface. In addition, the first port 321 may also be used to send network instructions, network data, or other network information generated by the network transceiver 320 to the network interface. In other words, the first port 321 may enable information exchange between the network interface and the network transceiver 320.

[0071] Optionally, the network instructions or network data between the network interface and the network transceiver 320 may satisfy the TCP / IP protocol. In other words, the network instructions or network data between the network interface and the network transceiver 320 may be TCP / IP instructions or TCP / IP data.

[0072] The second port 322 in the network transceiver 320 is used to connect to a control device or a power management device in the electronic device. The control device can be, for example, the above-mentioned Figure 1 or Figure 2 In the SoC of the embodiment shown, the power management device may be, for example, the Figure 1 or Figure 2 Alternatively, in some alternative implementations, the control device may also be a central processing unit (CPU) or other types of controllers or processors.

[0073] In some embodiments, the power management device and the control device can be separately configured as two circuit modules, such as two separate chips. In other embodiments, the power management device and the control device can also be integrated into one circuit module, such as integrating power management related circuits into a SoC chip.

[0074] When the power management device and the control device are separately configured as two circuit modules, the network transceiver 320 can send a wake-up instruction to the power management device 340 via the second port 322, so that the power management device 340 controls the control device and other modules in the electronic device to enter a wake-up state.

[0075] The processor 323 is a processing module in the network transceiver device 320. When the network transceiver device 320 is a network transceiver chip, the processor 323 is a data processing module in the chip. The processor 323 is used to obtain a preset network wake-up condition and determine whether the network instruction meets the network wake-up condition. If the network instruction meets the network wake-up condition, it generates a wake-up instruction. Optionally, the processor 323 can obtain the preset network wake-up condition from the outside. For example, the processor 323 can obtain the preset network wake-up condition from a memory. The memory can be a storage module in the network transceiver device 320 or a storage module in an electronic device. For another example, the processor 323 can also obtain the preset network wake-up condition from a control device. The preset network wake-up condition can include a user-defined network wake-up condition.

[0076] Based on the technical solution provided in the embodiment of the present application, a network transceiver device can be used to obtain a preset network wake-up condition, and when the electronic device is in a network standby state, it can be determined whether the network instruction received from the network interface meets the preset network wake-up condition, thereby realizing the wake-up function of the electronic device. The network transceiver device can replace the control device to monitor the network instruction and perform the wake-up function, which is beneficial to reducing the overall operating power consumption of the electronic device. In addition, the embodiment of the present application does not need to introduce an additional low-power device to implement the wake-up function, which is beneficial to reducing the complexity of the system and thus reducing the cost of the electronic device. Furthermore, the network transceiver device can perform wake-up based on the preset network wake-up condition, and thus can support user-defined network wake-up function, which can improve the user's satisfaction with the use of the electronic device and is beneficial to the further promotion and use of the electronic device.

[0077] Optionally, in the technical solution of the above embodiment, the power consumption of the network transceiver device may be less than or equal to 0.1 watt (W). For example, the power consumption of the network transceiver device may be between 0.025 W and 0.0825 W. The power consumption of the network transceiver device may be much less than the power consumption of the control device (such as a SoC).

[0078] Optionally, by implementing the wake-up function of the electronic device through the network transceiver, the standby power consumption of the electronic device in the network standby state can be reduced to less than or equal to 2W. In some embodiments, the standby power consumption of the electronic device can be reduced to less than 0.5W. This electronic device can have a low standby power consumption in the network standby state and can meet relevant green energy-saving standards, which is conducive to the promotion and use of electronic devices.

[0079] Optionally, the preset network wake-up condition acquired by the network transceiver includes: a user-defined network wake-up condition. The user-defined network wake-up condition may include, for example, a user-defined network wake-up instruction.

[0080] In some embodiments, the preset network wake-up condition may be a single network wake-up instruction or a network wake-up instruction set including one or more instructions. When the electronic device is in a standby state, the network transceiver device may receive network instructions sent by the network interface in real time. When the network transceiver device determines that a received network instruction corresponds to the single network wake-up instruction or to any instruction in the network wake-up instruction set, the processor in the network transceiver device may generate a wake-up instruction.

[0081] The technical solution of the embodiment of the present application can wake up the electronic device through the network through a network instruction corresponding to the network wake-up instruction or any instruction in the network wake-up instruction set, making the network wake-up instruction optional and making the network wake-up more convenient.

[0082] Optionally, the network instruction satisfies the network wake-up condition, and the network instruction may correspond to a single network wake-up instruction, or may correspond to any instruction in the network wake-up instruction set. The above correspondence may include multiple correspondence methods. For example, the network instruction is the same as the network wake-up instruction; for another example, the network instruction can be calculated or transcoded to obtain the same instruction as the network wake-up instruction; for another example, the network wake-up instruction and the network instruction perform certain calculations to obtain a preset result. This application does not limit the correspondence method between the network instruction and the network wake-up instruction.

[0083] Optionally, the network wake-up condition obtained by the network transceiver may be obtained through a network, or may be input by a user into the electronic device.

[0084] In some embodiments, the network transceiver device may obtain the network wake-up condition from the control device of the electronic device, i.e., the control device of the electronic device sends the network wake-up condition to the network transceiver device. As an example, the control device may obtain the network wake-up condition input by a user, who may enter the network wake-up condition directly into the electronic device or may enter the network wake-up condition into the electronic device via the network.

[0085] Optionally, the control device may send the network wake-up condition to the network transceiver immediately based on a user's instruction or automatically based on a preset instruction of the user or the electronic device. For example, the control device may first store the obtained network wake-up condition and then, based on a preset instruction, automatically send the network wake-up condition to the network transceiver upon receiving a network standby instruction.

[0086] Optionally, the network transceiver device may further include a third port, through which the network transceiver device is connected to the control device, and before the electronic device enters the network standby state, the third port is used to receive a preset network wake-up condition sent by the control device.

[0087] Figure 4 It is a schematic diagram of another network transceiver device provided in an embodiment of the present application.

[0088] like Figure 4As shown, the network transceiver 420 includes a first port 421, a second port 422, a third port 423, and a processor 424. The third port 423 is connected to the control device 430. Before the electronic device enters the network standby state, the third port 423 is used to receive a preset network wake-up condition, such as a user-defined network wake-up instruction set, sent by the control device 430. Then, when the electronic device enters the network standby state, the network transceiver 420 can receive a network instruction sent by the network interface 410 via the first port 421. Furthermore, the network transceiver 420 can determine whether the received network instruction meets the preset network wake-up condition via the processor 424. If the network instruction meets the network wake-up condition, the processor 424 can generate a wake-up instruction. This wake-up instruction can be transmitted to the control device 430 or the power management device 440 via the second port 422, thereby controlling the electronic device to enter the wake-up state from the standby state.

[0089] Based on the above Figure 4 The network transceiver device of the embodiment shown, Figure 5 A network wake-up method for a network transceiver provided by an embodiment of the present application is shown. In the network wake-up method, the preset network wake-up condition includes: a user-defined network wake-up instruction.

[0090] like Figure 5 As shown, the network wake-up method of the network transceiver device includes the following steps:

[0091] S510, the network transceiver receives a network instruction.

[0092] When the network transceiver of the electronic device receives the network command, the electronic device is already in a network standby state, the network transceiver has stored a user-defined network wake-up command, and the network transceiver monitors information received from the network interface. When the network transceiver receives the network command from the network interface, the process proceeds to step S520.

[0093] The network instruction may be any type of instruction. For example, the network instruction may be a TCP / IP instruction. Correspondingly, the network wake-up condition includes a preset TCP / IP instruction.

[0094] S520: The network transceiver device determines whether the network instruction is the same as the customized network wake-up instruction.

[0095] When the network transceiver of the electronic device in the network standby state receives a network command, the network transceiver compares the network command with the stored network wake-up command. If the network command is the same as the preset network wake-up command, the process proceeds to step S530; otherwise, the network transceiver returns to step S510.

[0096] S530: The network transceiver device sends a wake-up instruction to the power management device or the control device.

[0097] The network transceiver generates a wake-up instruction and sends the wake-up instruction to the power management device or the control device to wake up the electronic device from the network standby state.

[0098] The power management device and the control device may be separate. Step S530 may be implemented in a variety of ways. For example, the network transceiver may send a wake-up instruction to the power management device, which in turn wakes up the control device, causing the control device to wake up the electronic device. Another example is the network transceiver may directly send a wake-up instruction to the control device, causing the control device to wake up the electronic device.

[0099] The power management device and the control device may also be integrated. Then, step S530 may be that the network transceiver sends a wake-up instruction to the control device, and the control device wakes up the electronic device.

[0100] Optionally, in the above Figure 5 Before the network wake-up method shown, the network transceiver device may first obtain a preset network wake-up condition. Figure 6 Another network wake-up method of the network transceiver device provided in an embodiment of the present application is shown.

[0101] like Figure 6 As shown, the network standby method of the network transceiver device includes the following steps:

[0102] S610: The control device receives a user-defined network wake-up instruction input.

[0103] When the electronic device is in normal operation, the user can input a customized network wake-up instruction into the electronic device so that the control device in the electronic device can receive the network wake-up instruction. Optionally, the control device can further store the network wake-up instruction.

[0104] S620: The network transceiver receives a network wake-up instruction sent by the control device.

[0105] S630: The control device controls the electronic device to enter a network standby state.

[0106] After the electronic device enters the network standby state, the control device can be in the standby state or the off state. The network transceiver can be in the standby state or the normal operation state. In these two states, the network transceiver can receive and monitor network instructions or other information sent by the network interface.

[0107] Optionally, before step S630, the control device may also receive a standby instruction input by the user. Based on the standby instruction input by the user, the control device controls the electronic device to enter the network standby state. This step may occur simultaneously with or before step S620, and the order of the steps is not limited in this embodiment of the present application.

[0108] S640: The network transceiver receives a network instruction.

[0109] S650: The network transceiver device determines whether the network instruction is the same as the customized network wake-up instruction.

[0110] S660: The network transceiver device sends a wake-up instruction to the power management device or the control device.

[0111] The specific implementation of the above steps S640 to S660 can be found in the above Figure 5 The relevant description of the embodiment shown is not repeated here (steps S640 to S660 are not included in the description). Figure 6 (The winning bid is out).

[0112] The above describes the functional architecture and some wake-up methods of a network transceiver provided by an embodiment of the present application in combination with the basic framework of the network transceiver. The following describes the wake-up circuit architecture of the electronic device in which the network transceiver provided by an embodiment of the present application is located.

[0113] Figure 7 A circuit block diagram of a wake-up circuit provided in an embodiment of the present application is shown.

[0114] like Figure 7 As shown, the wake-up circuit includes: a network interface 710, a network transceiver 720 and a control device 730. The network interface 710 may be an RJ45 interface, which is used to connect to the network and send and receive data and / or instructions through the network. The network transceiver 720 may be a port physical layer, for example, the port physical layer may be as follows Figure 7 The CH392(S) chip shown in FIG. The control device 730 may be a SoC. Optionally, the wake-up circuit may further include a power management device 740.

[0115] The network transceiver 720 can be a customized chip or an improved version of an existing chip with added functionality. For example, the CH392(S) chip shown in the figure is a chip based on the existing CH392F chip with firmware added. The added firmware enables the CH392(S) chip to enter a network standby state, implement a standby monitoring function, determine whether received information is a network wake-up command, and wake up the electronic device when a network wake-up command is recognized.

[0116] The technical solution of the embodiment of the present application can realize the functions provided by the present application at a lower cost by making modifications based on the existing CH392F chip, thereby reducing the standby power consumption of electronic devices when the network wake-up function is turned on, without the need to add too much additional supporting software and hardware, and the modification is simple and easy to maintain.

[0117] Optionally, a network switching device is further connected between the first port of the network transceiver device and the network interface, and the network instruction is transmitted to the first port through the network switching device.

[0118] For example, Figure 8 FIG. 1 shows a schematic structural diagram of another wake-up circuit provided by the present application. Figure 8 As shown, the wake-up circuit includes: a network interface 810, a network switch 820, a network transceiver 830, and a control device 840. The network switch 820 may be an Ethernet switch. A first port of the network switch 820 is connected to the network interface 810, and a second port is connected to the network transceiver 830. The network switch 820 may also include a third port for connecting to the control device 840. The wake-up circuit may also include a power management device 850. Network commands are transmitted to the first port of the network switch 820 via the network switch 820.

[0119] Through the network switching device, electronic devices can transmit information to the network at higher speeds. For example, electronic devices can transmit information to the network at 100 megabits per second (Mbps) or 1000 Mbps through the network switching device 820. Different network transmission methods can be used for different information transmission rates. For example, when the third port of the network switching device 820 is connected to the control device 840, different network transmission methods can be used according to the real-time network transmission rate. For example, when the transmission rate between the electronic device and the network is lower than a first threshold, for example, when the transmission rate is lower than 10 Mbps, the network switching device 820 transmits information to the control device 840 via the network transceiver 830. When the transmission rate between the electronic device and the network is higher than or equal to the first threshold, for example, when the transmission rate is higher than or equal to 10 Mbps, the network switching device 820 transmits information directly to the control device 840 without using the network transceiver 830.

[0120] In the above embodiment, the wake-up circuit also includes a network switching device 820. When the electronic device is in a network standby state, the network interface 810 and the network switching device 820 maintain a certain information transmission function; when the network interface 810 receives a network instruction, it sends the network instruction to the network switching device 820; when a network instruction is received, the network switching device 820 sends the network instruction to the network transceiver 830; the network transceiver 830 monitors the received network instruction and determines whether the received network instruction is a network wake-up instruction. When the network transceiver 830 determines that the received network instruction is a network wake-up instruction, the network transceiver 830 sends a wake-up instruction to the power management device 850 or the control device 840 to wake up the electronic device.

[0121] The technical solution provided in this application enables electronic devices that support higher speeds, such as 100M / 1000M Ethernet, to achieve network standby and network wake-up functions by introducing a network switching device.

[0122] Optionally, the network switching device is further connected to one or more device interfaces, and the network switching device is connected to one or more devices through the one or more device interfaces.

[0123] Optionally, the network switching device may have a routing function. Figure 9 FIG. 1 shows a schematic structural diagram of another wake-up circuit provided by the present application. Figure 9 As shown, the wake-up circuit includes: a network interface 911, a device interface 912, a network switch 920, a network transceiver 930, and a control device 940. Device interface 911 can be an RJ45-IN interface, and device interface 912 can be an RJ45-OUT interface. The RJ45-IN interface can be used to connect to the network, and the RJ45-OUT interface can be used to connect to other terminal devices. The Ethernet transceiver 920 can be an Ethernet switch. The RJ45-IN interface and the RJ45-OUT interface are used in conjunction with the Ethernet switch to implement the routing function of the Ethernet switch. The first port of the network switch 920 includes at least one first terminal and at least one second terminal, the first terminal and the second terminal being respectively used to connect to the RJ45-IN interface and the RJ45-OUT interface. The network switch 920 also includes a second port and a third port, which are respectively used to connect to the network transceiver 930 and the control device 940. The network switch 920 transmits information to the network via the RJ45-IN interface, which serves as the network interface 911. The network switching device can transmit multiple network commands sent by multiple network interfaces to the first port of the network transceiver device through the RJ45-IN interface and the RJ45-OUT interface. Optionally, the wake-up circuit may further include a power management device 950 .

[0124] The technical solution provided in this application enables electronic devices with routing functions to realize network standby and network wake-up functions.

[0125] Figure 10 This is a schematic structural diagram of another wake-up circuit provided in this application.

[0126] like Figure 10 As shown, the wake-up circuit includes a network interface 1010, a network transceiver 1020, a control device 1070, and may also include a power management device 1080.

[0129] When the network transceiver 1020 receives a network instruction and determines that it is a network wake-up instruction, it sends the wake-up instruction to the power management device 1080 or the network transceiver 1020 through the output terminal. After receiving the wake-up instruction, the power management device 1080 or the control device 1070 wakes up the electronic device.

The reset circuit 1040 control device 1070 transmits a reset signal to the network transceiver 1020 through the reset circuit 1040. When the network transceiver 1020 receives the reset signal, the network transceiver 1020 is reset.

[0135] The reset signal may be a low-level signal and a high-level signal that are successively sent by the control device to the network transceiver device through the reset circuit, so that the network transceiver device can be reset.

[0137] Specifically, the output data of the control device 1070 is serial port data, which is transmitted to the network transceiver device 1020 via the serial port circuit 1050. The processor in the network transceiver device 1020 can be used to convert the serial port data sent by the control device into network data, which is then sent to the network interface. In addition, the processor in the network transceiver device 1020 can also convert the network data sent by the network interface into serial port data, which is then sent to the control device. The serial port data sent to the control device can also be referred to as first serial port data, and the serial port data sent by the control device can also be referred to as second serial port data; the network data sent by the network interface can also be referred to as first network data, and the network data sent to the network interface can also be referred to as second network data.

[0138] In addition, the serial port circuit 1050 can also be used for the control device 1070 to send network instructions to the network transceiver device 1020 through it. For example, the control device 1070 can send a network wake-up instruction to the network transceiver device 1020 through the serial port circuit 1050.

[0139] The switch circuit 1060 is connected between the control device 1070 and the network transceiver 1020 and is used for the control device 1070 to control the network transceiver to be turned on, turned off, or enter a network standby state.

[0140] The protection circuit 1090 is connected between the network transceiver 1020 and the network interface 1010 , and includes a transformer for isolating the first port of the network transceiver 1020 from the network interface 1010 .

Alternatively, the RXD pin and TXD pin can be the third port of the network transceiver device in the above embodiment.

Optionally, to distinguish it from other ports of the network transceiver, the RST pin may also be referred to as a fifth port of the network transceiver.

[0150] UN1 further includes a VCC pin, a VCC1 pin, and a VCC2 pin. The VCC pin, the VCC1 pin, and the VCC2 pin can be connected to a power supply terminal ETH_VCC of the circuit for receiving a power supply signal.
