[0039] Embodiment 1

[0040] Please refer to Figure 1 , Embodiment 1 of the present invention is: a millimeter wave wireless connector chip, which can be applied to a wireless connector.

[0041] like Figure 1 As shown, it includes a data interface module 1, a serial-to-parallel conversion module 2, a millimeter wave transceiver module 3 and a state machine control module 4. The data interface module 1, the serial-to-parallel conversion module 2 and the millimeter wave transceiver module 3 are connected in sequence 4, and the state machine control module 4 is respectively connected to the serial-to-parallel conversion module 2 and the millimeter wave transceiver module 3.

[0042] In this embodiment, the data interface module 1 is a data interface circuit for receiving or sending data signals. The serial-to-parallel conversion module 2 is a SERDES (short for serializer SERializer and deserializer DESerializer), which is used to convert parallel signals into serial signals and send the serial signals to the wireless transceiver module. It is also used to receive serial signals sent by the millimeter wave transceiver module and convert the received serial signals into parallel signals. The millimeter wave transceiver module 3 is a millimeter wave circuit for sending and receiving data via millimeter waves. The state machine control module 4 is a state machine control circuit for controlling the serial-to-parallel conversion module and the millimeter wave transceiver module to receive data, send data or sleep.

[0043] Furthermore, the data interface module is connected to the data signal pins of the chip.

[0044] The data signal to be transmitted is written into the data interface module through the input pin in the data signal pin. The data interface module sends the data signal to the serial-to-parallel conversion module. At this time, the data signal is a parallel signal. The serial-to-parallel conversion module then converts the parallel signal into a serial signal, which is finally sent out through the millimeter wave module.

[0045] The millimeter wave wireless connector chip can also receive data signals sent by other chips through the millimeter wave module, and then send them to the data interface module after conversion through the serial-to-parallel conversion module, and finally output them through the output pins in the data signal pins.

[0046] This embodiment reduces the cost and complexity of implementing the wireless connection function by integrating the wireless transceiver function and the baseband processing function into the same chip and adding a data signal interface.

[0047] Embodiment 2

[0048] Please refer to Figure 2 This embodiment is a further extension of the first embodiment, and the similarities are not repeated here. The difference is that, in this embodiment, the millimeter wave wireless connector chip also includes a control interface module 5 and a register module 6, the control interface module 5 is connected to the register module 6, and the register module 6 is connected to the state machine control module 4.

[0049] In this embodiment, the control interface module 5 is a control interface circuit for receiving or sending control signals, and the control signals include control signals corresponding to the chip itself. The register module 6 is a register or a configuration register for storing control signals corresponding to the chip itself. The state machine control module 4 is also used to perform corresponding configuration according to the control signal in the register module 6; for example, to activate the chip according to the control signal, or to control the serial-to-parallel conversion module and the millimeter wave transceiver module.

[0050] Furthermore, the control interface module is connected to the control signal pins of the chip. The control signal can be written into the chip through the input pins of the control signal pins, and the control signal can also be read from the chip through the output pins of the control signal pins to verify it.

[0051] Based on the first embodiment, this embodiment further provides a control signal interface to implement the configuration of the millimeter wave wireless connector chip.

[0052] Embodiment 3

[0053] Please refer to Figure 3This embodiment is a further expansion of the second embodiment, and the similarities are not repeated. The difference is that, in this embodiment, the control signal also includes control signals corresponding to other chips; the millimeter wave wireless connector chip also includes a judgment and selection module 7, a bridge module 8, a packing module 9 and an unpacking distribution module 10; the control interface module 5 is connected to the judgment and selection module 7, the judgment and selection module 7 is respectively connected to the register module 6 and the bridge module 8, the bridge module 8 is respectively connected to the packing module 9 and the unpacking distribution module 10, and the data interface module 1 is respectively connected to the serial-to-parallel conversion module 2 through the packing module 9 and the unpacking distribution module 10.

[0054] In this embodiment, the judgment and selection module 7 is a judgment and selection circuit (which can be realized by a digital circuit), which is used to obtain the control signal corresponding to the state machine control module of its own chip from the control signal sent by the control interface module 5 and send it to the register module 6, obtain the control signal corresponding to other chips from the control signal sent by the control interface module 5 and send it to the bridge module 8, and obtain the control signal corresponding to the control interface module 5 of its own chip from the control signal sent by the bridge module 8 and send it to the control interface module 5. The bridge module 8 is a bridge circuit, which is used to forward the control signal, that is, to send the control signal sent by the control interface module 5 to the packaging module 9, and to send the control signal sent by the unpacking distribution module 10 to the judgment and selection module 7. The packaging module 9 is a data packaging circuit, which is used to package the control signal and the data signal to obtain a parallel signal, and send the packaged parallel signal to the serial-to-parallel conversion module 2. The unpacking distribution module 10 is an unpacking distribution circuit, which is used to unpack the parallel signal sent by the serial-to-parallel conversion module 2 to obtain a control signal and a data signal, and send the unpacked control signal to the judgment and selection module 7 through the bridge module 8, and send the unpacked data signal to the data interface module 1.

[0055] Furthermore, the control signal includes identifiers of corresponding chips and modules. The judgment and selection module determines which chip or module the control signal corresponds to through the identifiers in the control signal. If it is a control signal of a state machine control module corresponding to its own chip, the control signal is sent to the register module. If it is a control signal of a control interface module corresponding to its own chip, the control signal is sent to the control interface module. If it is a control signal corresponding to other chips, the control signal is sent to the bridge module, which is then forwarded to the packaging module by the bridge module.

[0056] After the packing module receives the control signals corresponding to other chips sent by the bridge module and the data signals sent by the data interface module, it packs the control signals and the data signals into parallel signals. The packed signals are sent to the serial-to-parallel conversion module, and then the serial-to-parallel conversion module converts the parallel signals into serial signals, which are finally sent to another millimeter-wave wireless connector chip through the millimeter-wave transceiver module.

[0057] In another millimeter wave wireless connector chip, after receiving the serial signal through the millimeter wave module, the serial signal is sent to the serial-to-parallel conversion module, and the serial-to-parallel conversion module converts the serial signal into a parallel signal and sends it to the unpacking distribution module; after receiving the parallel signal, the unpacking distribution module unpacks it to obtain the control signal and the data signal, and sends the unpacked control signal to the judgment and selection module through the bridge module, and sends the unpacked data signal to the data interface module. The judgment and selection module judges whether the control signal sent by the bridge module is the control signal corresponding to the state machine control module of its own chip. If so, the control signal is sent to the register module; otherwise, it judges whether the control signal sent by the bridge module is the control signal corresponding to the control interface module of its own chip. If so, the control signal is sent to the control interface module, and the control interface module is sent to the device connected to it through the output pin in the control signal pin. In other words, the control signal corresponding to the control interface module of the chip is equivalent to the control signal corresponding to the device connected to the chip.

[0058] For example, assume that device A is connected to millimeter wave wireless connector chip A (hereinafter referred to as chip A), and device B is connected to millimeter wave wireless connector chip B (hereinafter referred to as chip B). Furthermore, device A is respectively connected to the control signal pin and data signal pin of chip A, and device B is connected to the control signal pin and data signal pin of chip B; chip A and chip B are wirelessly connected.

[0059] Device A can send the data to be transmitted to chip A through the data signal pin, and chip A wirelessly sends it to chip B. Chip B then sends the data to be transmitted to device B through the data signal pin, thereby realizing data signal communication between device A and device B.

[0060] Device A can also send a control signal to chip A through a control signal pin, wherein the control signal includes a control signal corresponding to chip A, and may also include a control signal corresponding to chip B and a control signal corresponding to device B; chip A stores its own corresponding control signal in its own register module, and wirelessly sends the control signal corresponding to chip B and the control signal corresponding to device B to chip B; after chip B receives the control signal, it determines through its own judgment and selection module that the control signal is the control signal corresponding to its own chip, and then stores the control signal in its own register module. If it determines that the control signal is the control signal corresponding to device B, it sends the control signal to its own control interface module, and then sends it to device B via the output pin of the control signal pin, thereby realizing the control of the remote chip and remote device.

[0061] That is to say, chip A, chip B and device B can be configured by device A at the same time, that is, the chip at the sending end and the chip and device at the receiving end can be configured by the device at the sending end at the same time, and the device at the receiving end does not need to set up a control module, such as an MCU.

[0062] In addition to configuring the near-end millimeter wave wireless connector chip, this embodiment can also configure the far-end millimeter wave wireless connector chip and the far-end device.

[0063] In summary, the millimeter wave wireless connector chip, wireless connector and signal transmission system provided by the present invention greatly reduce the cost and complexity of realizing the wireless connection function by integrating the wireless transceiver function and the baseband processing function into the same chip, and adding a data signal interface and a control signal interface; at the same time, it can realize the control of the near-end millimeter wave wireless connector chip, and can also realize the configuration of the far-end millimeter wave wireless connector chip and the far-end device, so that the far-end device does not need to set a control module, further reducing the cost of the overall system.
