Technical Field

[0001] This application relates to the field of network communication technology, and in particular to a module and network communication device for transmitting Ethernet signals based on a Type-C interface. Background Technology

[0002] Network communication devices can extend network connectivity by providing multiple ports to connect multiple terminal devices. Indoor network communication devices are small in size and are typically used in hospitals, small offices, homes, schools, and other similar locations. When a customer needs to add more devices, they often expand the ports by cascading another network communication device. However, adding a new device requires additional power cables, increasing the cabling complexity.

[0003] In related technologies, standard Ethernet signals are transmitted and powered through Ethernet cables; however, this transmission method requires the addition of adapters at the connection ends of the Ethernet cables, which takes up more installation space; at the same time, it also requires the addition of Power over Ethernet (POE) chips in network communication equipment, resulting in high costs.

[0031] Type-C cables can both supply power and transmit signals. Therefore, in related technologies, replacing Ethernet cables with Type-C cables expands network communication devices without the need for adapters or PoE chips within the network communication devices.

[0032] However, Type-C cables transmit USB signals and cannot transmit Ethernet signals.

[0033] This application provides a module for transmitting Ethernet signals based on a Type-C interface. The Type-C interface is redefined according to the Ethernet definition, enabling the Type-C interface to transmit Ethernet signals. At the same time, a PHY chip is added, and the polarity correction function of the PHY chip is used to ensure that the Ethernet signal is transmitted in the correct manner, thereby achieving the purpose of adapting to the common Type-C cable.

[0034] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0035] refer to Figure 1 This application provides a module for transmitting Ethernet signals based on a Type-C interface, which includes a Type-C interface.

[0036] The Type-C interface includes an uplink signal pin combination and a downlink signal pin combination.

[0037] The uplink signal pin combination includes: first ground pin A1, first uplink signal pin A2, second uplink signal pin A3, first power transmission pin A4, first direction pin A5, first floating pin A6, second floating pin A7, third floating pin A8, second power transmission pin A9, third uplink signal pin A10, fourth uplink signal pin A11, and second ground pin A12, for a total of 12 pins.

[0038] The downlink signal pin combination includes: third ground pin B12, first downlink signal pin B11, second downlink signal pin B10, third power transmission pin B9, fourth floating pin B8, fifth floating pin B7, sixth floating pin B6, second direction pin B5, fourth power transmission pin B4, third downlink signal pin B3, fourth downlink signal pin B2 and fourth ground pin B1, for a total of 12 pins.

[0039] Among them, the first uplink signal pin A2, the second uplink signal pin A3, the third uplink signal pin A10, the fourth uplink signal pin A11, the first downlink signal pin B11, the second downlink signal pin B10, the third downlink signal pin B3, and the fourth downlink signal pin B2 are all used to transmit Ethernet signals.

[0040] Furthermore, the first uplink signal pin A2 and the first downlink signal pin B11 are symmetrical, the second uplink signal pin A3 and the second downlink signal pin B10 are symmetrical, the third uplink signal pin A10 and the third downlink signal pin B3 are symmetrical, and the fourth uplink signal pin A11 and the fourth downlink signal pin B2 are symmetrical, so as to enable the module of this application to be connected to the peer device's peer Type-C interface via the Type-C interface in both forward and reverse directions.

[0041] The correct orientation of the Type-C interface on this end and the correct orientation of the Type-C interface on the other end refers to the insertion direction of the Type-C interface. Correct orientation means that the front side of the Type-C interface is facing up when it is inserted into the socket, and incorrect orientation means that the back side of the Type-C interface is facing up when it is inserted into the socket. The Type-C interface can work normally regardless of whether the front side or the back side of the plug is facing up.

[0042] Meanwhile, the first grounding pin A1 and the second grounding pin A12 are symmetrical, the first power transmission pin A4 and the second power transmission pin A9 are symmetrical, the third grounding pin B12 and the fourth grounding pin B1 are symmetrical, the third power transmission pin B9 and the fourth power transmission pin B4 are symmetrical, the first floating pin A6 and the second floating pin A7 are symmetrical, the fifth floating pin B7 and the sixth floating pin B6 are symmetrical, the first direction pin A5 and the third floating pin A8 are symmetrical, and the fourth floating pin B8 and the second direction pin B5 are symmetrical.

[0043] The first ground pin A1, the second ground pin A12, the first power transmission pin A4, the second power transmission pin A9, the third ground pin B12, the fourth ground pin B1, the third power transmission pin B9, and the fourth power transmission pin B4 are all used for charging and powering the Type-C interface, so that the Type-C interface can be connected to an external power supply device, or so that the Type-C interface can supply power to other communication devices.

[0044] The first floating pin A6, the second floating pin A7, the third floating pin A8, the fourth floating pin B8, the fifth floating pin B7, and the sixth floating pin B6 are all left floating and not connected.

[0045] When the second direction pin B5 is left floating and not connected, the Type-C interface is connected in the correct direction; when the first direction pin A5 is left floating and not connected, the Type-C interface is connected in the reverse direction.

[0046] Continue to refer to Figure 1 In this embodiment of the application, the first uplink signal pin A2 is the network differential signal MDI1+, the second uplink signal pin A3 is the network differential signal MDI3+, the third uplink signal pin A10 is the network differential signal MDI4+, and the fourth uplink signal pin A11 is the network differential signal MDI2+.

[0047] The first downlink signal pin B11 is the network differential signal MDI1-, the second downlink signal pin B10 is the network differential signal MDI3-, the third downlink signal pin B3 is the network differential signal MDI4-, and the fourth downlink signal pin B2 is the network differential signal MDI2-.

[0048] refer to Figure 2In a standard Ethernet connection, the MDI1+ of the local Type-C interface is connected to the MDI1+ of the remote Type-C interface; the MDI1- of the local Type-C interface is connected to the MDI1- of the remote Type-C interface; the MDI2+ of the local Type-C interface is connected to the MDI2+ of the remote Type-C interface; the MDI2- of the local Type-C interface is connected to the MDI2- of the remote Type-C interface; the MDI3+ of the local Type-C interface is connected to the MDI3+ of the remote Type-C interface; the MDI3- of the local Type-C interface is connected to the MDI3- of the remote Type-C interface; the MDI4+ of the local Type-C interface is connected to the MDI4+ of the remote Type-C interface; and the MDI4- of the local Type-C interface is connected to the MDI4- of the remote Type-C interface.

[0049] This means that the correct transmission of Ethernet signals can only be achieved when the pin polarities of the local Type-C interface are the same as those of the remote Type-C interface, and the pins of the local Type-C interface correspond one-to-one with those of the remote Type-C interface.

[0050] refer to Figure 3 When the local Type-C interface and the remote Type-C interface are connected in the correct order, the MDI1+ of the local Type-C interface is connected to the MDI1- of the remote Type-C interface, the MDI1- of the local Type-C interface is connected to the MDI1+ of the remote Type-C interface, the MDI2+ of the local Type-C interface is connected to the MDI2- of the remote Type-C interface, the MDI2- of the local Type-C interface is connected to the MDI2+ of the remote Type-C interface, the MDI3+ of the local Type-C interface is connected to the MDI3- of the remote Type-C interface, the MDI3- of the local Type-C interface is connected to the MDI3+ of the remote Type-C interface, the MDI4+ of the local Type-C interface is connected to the MDI4- of the remote Type-C interface, and the MDI4- of the local Type-C interface is connected to the MDI4+ of the remote Type-C interface.

[0051] This means that when the local Type-C interface and the remote Type-C interface are connected in the correct orientation, the pin polarity of the local Type-C interface is opposite to that of the remote Type-C interface. In this case, the correct transmission of Ethernet signals cannot be achieved when using a general Type-C cable to connect the local Type-C interface and the remote Type-C interface.

[0052] In other words, when the Type-C interface on this end and the Type-C interface on the other end are connected in the correct order, it does not support universal Type-C cables, resulting in poor compatibility.

[0053] In this embodiment of the application, the module for transmitting Ethernet signals based on the Type-C interface further includes: a correction chip, which includes a polarity correction chip and / or an automatic crossover chip.

[0054] The polarity correction chip has a polarity correction function, which can automatically detect the received signal to determine whether the polarity of the signal is correct. If a polarity error is detected, the polarity correction chip will automatically adjust the polarity of the signal to match the expected signal polarity, ensuring that communication between devices can proceed normally.

[0055] Polarity correction chips can be physical layer transceiver (PHY) chips, reverse connection protection chips, power controller chips, audio amplifier chips, digital signal processing chips, differential transceiver chips, or video signal processing chips, etc.

[0056] Among them, polarity correction chips such as PHY chips have polarity correction functions, which can automatically adjust the polarity of the signal to match the expected signal polarity, ensuring normal communication between devices. Reverse connection protection chips typically integrate diodes or metal-oxide-semiconductor field-effect transistors (MOSFETs) to automatically correct the power supply polarity, preventing circuit damage caused by reversed power supply polarity.

[0057] The power controller chip has a built-in polarity detection and correction function to ensure the correctness of the power input.

[0058] The audio amplifier chip has a phase correction function to ensure the polarity of the audio signal is consistent, thereby improving sound quality.

[0059] Digital signal processing chips include polarity correction functionality to process inverted signals.

[0060] Differential transceiver chips have polarity detection and automatic correction functions to ensure correct data transmission.

[0061] The video signal processing chip has a polarity correction function to ensure the phase consistency of the image signal.

[0062] When the local Type-C interface and the remote Type-C interface are connected in the correct orientation, the polarity correction function of the polarity correction chip is used to correct the polarity of the local signal pins so that the polarity of the signal pair formed by the signal pins of the local Type-C interface and the signal pins of the remote Type-C interface is the same.

[0063] That is, to Figure 4 The MDI1- of the local Type-C interface is modified to MDI1+, so that the MDI1+ of the local Type-C interface is connected to the MDI1+ of the remote Type-C interface; Figure 4 The MDI1+ of the local Type-C interface is modified to MDI1-, so that the MDI1- of the local Type-C interface is connected to the MDI1- of the remote Type-C interface; Figure 4 The MDI2- of the local Type-C interface is modified to MDI2+, so that the MDI2+ of the local Type-C interface is connected to the MDI2+ of the remote Type-C interface; Figure 4 The MDI2+ of the local Type-C interface is modified to MDI2-, so that the MDI2- of the local Type-C interface is connected to the MDI2- of the remote Type-C interface; Figure 4 The MDI3- of the local Type-C interface is modified to MDI3+, so that the MDI3+ of the local Type-C interface is connected to the MDI3+ of the remote Type-C interface; Figure 4 The MDI3+ of the local Type-C interface is modified to MDI3-, so that the MDI3- of the local Type-C interface is connected to the MDI3- of the remote Type-C interface; Figure 4 The MDI4- of the local Type-C interface is modified to MDI4+, so that the MDI4+ of the local Type-C interface is connected to the MDI4+ of the remote Type-C interface; Figure 4 The MDI4+ of the local Type-C interface is modified to MDI4-, so that the MDI4- of the local Type-C interface is connected to the MDI4- of the remote Type-C interface.

[0064] refer to Figure 5 When the local Type-C interface, after being corrected by the polarity correction chip, is connected to the remote Type-C interface, the following connections are made: MDI1+ of the local Type-C interface is connected to MDI1+ of the remote Type-C interface; MDI1- of the local Type-C interface is connected to MDI1- of the remote Type-C interface; MDI2+ of the local Type-C interface is connected to MDI2+ of the remote Type-C interface; MDI2- of the local Type-C interface is connected to MDI2- of the remote Type-C interface; MDI3+ of the local Type-C interface is connected to MDI3+ of the remote Type-C interface; MDI3- of the local Type-C interface is connected to MDI3- of the remote Type-C interface; MDI4+ of the local Type-C interface is connected to MDI4+ of the remote Type-C interface; and MDI4- of the local Type-C interface is connected to MDI4- of the remote Type-C interface.

[0065] At this point, using a standard Type-C cable to connect the local Type-C interface and the remote Type-C interface will enable correct transmission of Ethernet signals.

[0066] refer to Figure 6 When the local Type-C interface and the remote Type-C interface are reversed, MDI1+ of the local Type-C interface is connected to MDI2+ of the remote Type-C interface, MDI1- of the local Type-C interface is connected to MDI2- of the remote Type-C interface, MDI2+ of the local Type-C interface is connected to MDI1+ of the remote Type-C interface, and MDI2- of the local Type-C interface is connected to MDI1- of the remote Type-C interface; MDI3+ of the local Type-C interface is connected to MDI4+ of the remote Type-C interface, MDI3- of the local Type-C interface is connected to MDI4- of the remote Type-C interface, MDI4+ of the local Type-C interface is connected to MDI3+ of the remote Type-C interface, and MDI4- of the local Type-C interface is connected to MDI3- of the remote Type-C interface.

[0067] This means that when the local Type-C interface and the remote Type-C interface are reversed, the pins of the local Type-C interface and the remote Type-C interface do not correspond one-to-one. In this case, the correct transmission of Ethernet signals cannot be achieved when using a Type-C to Type-C cable from a general Type-C cable to connect the local Type-C interface and the remote Type-C interface.

[0068] In other words, when the Type-C interface on this end and the Type-C interface on the other end are reversed, it does not support universal Type-C cables, resulting in poor compatibility.

[0069] In this embodiment, the automatic crossover chip has an automatic crossover function (Medium Dependent Interface / Medium Dependent Interface Crossover, or MDI / MDI-X function for short), which can automatically detect the arrangement of internal wires and automatically adjust the pin configuration of its transmit and receive signals according to the arrangement to ensure correct communication.

[0070] The internal line sequence arrangement methods mentioned above include straight-through line sequence and cross-line sequence.

[0071] refer to Figure 2A straight-through cable has the same wiring sequence at both ends and is mainly used to connect different types of network devices, such as computer to switch, computer to router, or computer to modem.

[0072] refer to Figure 7 Crossover wiring has different wire sequences at both ends and is mainly used to connect the same type of network devices, such as switch to switch or computer to computer.

[0073] In other words, the automatic crossover chip in this application embodiment can adjust the configuration relationship of signal pairs according to the automatically detected internal wiring sequence (straight-through or crossover) so that when the Type-C interface is reversed, the pins of the Type-C interface on this end correspond one-to-one with the pins of the Type-C interface on the other end, thereby realizing the correct transmission of Ethernet signals.

[0074] refer to Figure 7 When the local Type-C interface and the remote Type-C interface are reversed, the automatic cross-connection chip of the local Type-C interface will internally perform logical port switching and redefine MDI2+ as MDI1+.

[0075] Similarly, refer to Figure 8 , Figure 8 The MDI1+ and MDI2+ interfaces of the local Type-C interface are swapped, so that the MDI1+ interface of the local Type-C interface is connected to the MDI1+ interface of the remote Type-C interface, and the MDI2+ interface of the local Type-C interface is connected to the MDI2+ interface of the remote Type-C interface.

[0076] Will Figure 8 The MDI1- and MDI2- of the local Type-C interface are swapped, so that the MDI1- of the local Type-C interface is connected to the MDI1- of the remote Type-C interface, and the MDI2- of the local Type-C interface is connected to the MDI2- of the remote Type-C interface.

[0077] Will Figure 8 The MDI3+ and MDI4+ interfaces of the local Type-C interface are swapped, so that the MDI3+ interface of the local Type-C interface is connected to the MDI3+ interface of the remote Type-C interface, and the MDI4+ interface of the local Type-C interface is connected to the MDI4+ interface of the remote Type-C interface.

[0078] Will Figure 8 The MDI3- and MDI4- of the local Type-C interface are swapped, so that the MDI3- of the local Type-C interface is connected to the MDI3- of the remote Type-C interface, and the MDI4- of the local Type-C interface is connected to the MDI4- of the remote Type-C interface.

[0079] This ultimately ensures that the pins of the Type-C interface on this end correspond one-to-one with the pins of the Type-C interface on the other end.

[0080] The automatic crossover chip can be a PHY chip. A PHY chip with automatic crossover functionality can automatically detect the internal pin arrangement and adjust the pin configuration for transmitting and receiving signals accordingly to ensure correct communication. Alternatively, the automatic crossover chip can be any other chip with automatic crossover functionality.

[0081] Therefore, the module for transmitting Ethernet signals based on the Type-C interface provided in this application redefines the Type-C interface according to the Ethernet definition, enabling the Type-C interface to transmit Ethernet signals; at the same time, it adds a polarity correction chip and an automatic crossover chip, utilizing the polarity correction function of the polarity correction chip and the automatic crossover function of the automatic crossover chip to ensure that the Ethernet signal is transmitted in the correct manner, thereby achieving the purpose of adapting to the common Type-C cable.

[0082] Of course, you can also add only a polarity correction chip and require the Type-C interface to be connected in the correct orientation only; or you can add only an automatic crossover chip and require the Type-C interface to be connected in the reverse orientation only.

[0083] It should be noted that the PHY chip has polarity correction and automatic crossover functions; that is, by simply adding a PHY chip, the Ethernet signal can be transmitted in the correct manner.

[0084] Meanwhile, when network connectivity needs to be expanded, simply interconnect the Type-C interfaces of network communication devices using a universal Type-C cable, enabling rapid cascading deployment of multiple network communication devices; avoiding the occupation of excessive installation space on site, preventing messy on-site wiring, and reducing the difficulty of maintenance and replacement.

[0085] Among them, the common Type-C cable can be a Type-C to Type-C cable.

[0086] In this embodiment, the signal pins also include other types of permutations and combinations.

[0087] refer to Figure 9 In one embodiment, the first uplink signal pin A2 can be the network differential signal MDI3+, the second uplink signal pin A3 can be the network differential signal MDI1+, the third uplink signal pin A10 can be the network differential signal MDI2+, and the fourth uplink signal pin A11 can be the network differential signal MDI4+.

[0094] The Type-C interfaces of any two network communication devices can be interconnected to achieve cascading deployment and facilitate network expansion.

[0095] In summary, this application provides a module and network communication device for transmitting Ethernet signals based on a Type-C interface. The module includes a Type-C interface and a correction chip. The Type-C interface includes an uplink signal pin combination and a downlink signal pin combination. The pins in the uplink signal pin combination used for transmitting Ethernet signals include a first uplink signal pin A2, a second uplink signal pin A3, a third uplink signal pin A10, and a fourth uplink signal pin A11. The pins in the downlink signal pin combination used for transmitting Ethernet signals include a first downlink signal pin B11, a second downlink signal pin B10, a third downlink signal pin B3, and a fourth downlink signal pin B2. The first uplink signal pin A2 and the first downlink signal pin B11 are used for transmitting Ethernet signals. The first uplink signal pin B11 is symmetrical, the second uplink signal pin A3 and the second downlink signal pin B10 are symmetrical, the third uplink signal pin A10 and the third downlink signal pin B3 are symmetrical, and the fourth uplink signal pin A11 and the fourth downlink signal pin B2 are symmetrical, so that the module can connect to the peer's Type-C interface through the Type-C interface. When the module is connected to the peer's Type-C interface through the Type-C interface, the correction chip is used to adjust the configuration relationship of the signal pairs of the Type-C interface and the peer's Type-C interface so that the polarity of the signal pairs is the same and that the local signal pins and the peer signal pins that make up the signal pairs correspond one-to-one. The Type-C interface includes the local signal pins, and the peer's Type-C interface includes the peer signal pins.

[0096] The Type-C interface is redefined according to the Ethernet definition, enabling it to transmit Ethernet signals. At the same time, a correction chip is added, utilizing its polarity correction and automatic crossover functions to ensure that Ethernet signals are transmitted correctly, thereby achieving compatibility with common Type-C cables.

[0097] Meanwhile, when network connectivity needs to be expanded, simply interconnect the Type-C interfaces of network communication devices using a universal Type-C cable, enabling rapid cascading deployment of multiple network communication devices; avoiding the occupation of excessive installation space on site, preventing messy on-site wiring, and reducing the difficulty of maintenance and replacement.
