Detailed Description

The following describes in further detail the embodiments of the present invention with reference to the drawings and examples. The following examples are illustrative of the invention and are not intended to limit the scope of the invention.

Based on the problems in the prior art, part of equipment manufacturers and companies make further improvements to the problems in order to make up for the defects, referring to fig. 1, fig. 1 is a schematic diagram of an existing data transmission device based on an electrical port PHY chip; in fig. 1, some manufacturers and companies have developed and developed to use proprietary serial transmission protocols (FPD-LINK/GMSL) to support coaxial line (Coax) or twisted pair (STP) transmission, and the transmission distance can be up to 15m, so that the distance between the camera/screen and the host, such as the current transmission between the camera, the screen and the host in the intelligent automobile, is effectively extended. Meanwhile, MIPI (Mobile Industry Processor Interface ) is also actively making an interface standard of A-PHY, and is targeted for being applied to the fields of intelligent automobiles and Internet of things (IOT). Support camera, screen zoom out to 15m distance.

Based on the problems in the prior art, in order to solve the second solution of the problem of camera/screen zoom out, refer to fig. 2, fig. 2 is a schematic diagram of the conventional data transmission device based on the interface conversion function; in fig. 2, the MIPI C/D-PHY interface is converted into a USB or ethernet interface by using an interface conversion function and using a specific protocol conversion chip, supporting longer-distance transmission.

Both of the above solutions, one of which can solve some of the problems due to the 15m distance change, cannot support longer distance and higher rate data transmission; and secondly, the MIPI C/D-PHY is converted into a USB interface, the USB interface is the universal serial interface which is most widely applied in the field of consumer electronics, the industry chain is mature, and the transmission distance can be expanded by multi-stage driving in a bridging mode through a redrive chip. Meanwhile, functions such as port expansion and the like can be supported through the USB hub, but the mode can increase cost and power consumption, and also brings problems such as time delay and safety. And the extended transmission distance is limited. And the MIPI C/D-PHY is converted into an Ethernet interface, which is the interface most widely applied in the communication field, and has complete interface serialization and covers the speed of 10M-800G and the distance coverage within 40 KM. However, the interface conversion still brings about the problems of high cost, high power consumption, complex technology, time delay, safety and the like.

Therefore, the invention provides a data transmission device based on an optical fiber as a transmission medium, which uses an O-PHY technology as another PHY technology different from an A/C/D-PHY in an MIPI interface, is mainly applied to high-speed video transmission between a camera/screen and a host, and can be widely applied to the fields of intelligent automobiles, security, medical treatment, intelligent home and the like which need long-distance transmission.

As an embodiment, the data transmission apparatus further includes: an I2C module; the I2C module is used for providing control management functions for the data transmission device.

In an embodiment of the present invention, an optical fiber-based data transmission device is provided, where the device includes: the device comprises a signal serialization module, a laser driving module, a laser generating module, a multimode optical fiber, a laser receiving module, a signal amplifying module and a signal deserializing module, wherein the signal serialization module is connected with the signal deserializing module sequentially through the laser driving module, the laser generating module, the multimode optical fiber, the laser receiving module and the signal amplifying module; compared with the prior art, the beneficial effects are as follows: the invention provides a PHY layer solution based on optical transmission, which has higher transmission rate (6G is improved to 10G) and longer transmission distance (15 m is improved to 100 m) compared with the PHY layer technologies such as C/D/A-PHY, LVDS, USB and the like; compared with the existing copper wire transmission scheme, the method has the advantages that the power consumption is lower, EMC interference is avoided, the used data threshold is greatly reduced, the time delay of data transmission is reduced, and the safety of data is improved.

In a possible application scenario, the device can also be used for video data transmission of a camera, referring to fig. 4, fig. 4 is a schematic diagram of a structure of a camera for realizing optical fiber transmission in a bridging manner provided by the invention; in fig. 4, the camera is mainly composed of modules such as LENS, CIS, transmitter, VCSEL laser, optical fiber, copper wire, PIN Receiver, I2C, power, etc.

The LENS and the CIS chip can be selected from corresponding universal devices (such as LENS and CIS processors in the vehicle-mounted field), the CIS and the Transmitter are connected through a C/D-PHY interface (the most universal interface of the CIS processor in the current industry chain is D-PHY, and a small part of the CIS processor is C-PHY), and the C/D-PHY interface is integrated inside the Transmitter. C/D-PHY interface connection is used between the CIS and the Transmitter (the most common interface of the CIS processor in the industry chain is D-PHY at present, and a small part of the CIS processor is C-PHY), and the C/D-PHY interface is integrated inside the Transmitter. The digital signal received from the C/D-PHY is serialized (serialized) and fed into a laser Driver (DRV) that is used to drive the VCSEL laser.

VCSEL (vertical cavity surface emitting laser) is a universal laser widely applied to multimode optical fiber transmission in the communication industry, is generally used for transmission distances below 100m, is only an example, and can be replaced by a DFB (distributed feedback) or EML (enhanced mode laser) commonly used for communication as required, and is matched with corresponding DRV (discontinuous mode) and Single Mode Fiber (SMF) to realize different transmission distance requirements. The VCSEL laser is coupled with the multimode optical fiber, different optical fiber lengths can be prepared according to the application scene requirement, and a pluggable optical fiber interface can be also manufactured to support the field installation of the optical fiber and the camera.

An I2C module is supported in the Transmitter, MIPI CCI (control management channel) is supported, and a Host can control and manage the Transmitter and the CIS chip through an I2C interface.

The Camera internal power module also supports the function of remote power supply, the power supply is connected with the I2C interface by using copper wires, the copper wires and the optical fibers form a photoelectric composite cable together, and all connection functions of a Camera are achieved by using only one cable. (remote supply is an optional function, and local power supply can be used according to actual application requirements.)

One end of the cable at the host side is connected with an optical Receiver PIN (different optical receivers such as APD can be selected according to the requirement) through a coupling mode, and then the optical fiber is connected with a Receiver chip, wherein TIA (transimpedance amplifier) is integrated in the Receiver chip to amplify weak electric signals sensed by the PIN, and the weak electric signals are sent to an MIPI C/D-PHY after passing through a Deserializer and are in butt joint with an SOC chip at the host side through an MIPI C/D-PHY interface.

The host side Receiver chip is internally integrated with an I2C interface module as the same as the Transmitter, and the host side SOC chip can control and manage the Receiver chip through the MIPI CCI interface and can manage the Transmitter and the CIS chip.

In fig. 4, the camera, the photoelectric composite cable, the Transmitter and the Receiver can be integrated as a whole device, and are in butt joint with the host computer SOC to complete the video acquisition function, and in practical application, the four components of the camera, the photoelectric composite cable, the Transmitter and the Receiver can be flexibly combined according to the needs and are divided into a plurality of components.

In the application scenario, the video data source is collected from the LENS, (the LENS is a LENS component commonly used in the industry), the external optical signal reaches the CIS chip (the CIS is a camera video signal processing chip commonly used in the industry), after video signal processing, the video signal is transmitted to the Transmitter through the MIPI interface (the protocol layer uses CSI-2 and the physical layer uses D-PHY), the Transmitter is a functional chip defined by the embodiment, the digital signal is recovered through the docking of the D-PHY interface with the CIS chip, and then is subjected to serialization processing, and converted into a high-speed serial signal to be sent to the DRV, (the DRV is a functional module in the chip and drives the VCSEL laser), the DRV drives the VCSEL laser, and the VCSEL laser is a laser chip widely used in the communication industry, wherein a 10G bps laser chip with mature technology can be selected, and a single channel can support the 10G rate (can support the highest rate D-PHY, 20mp,15hz camera application), so that the cost is low, and the power consumption is low. The video signal is converted into an optical signal after passing through the VCSEL, and the optical signal is coupled into an optical fiber for transmission, and the transmission distance can support 100m application. The optical fiber is coupled with the PIN Receiver after being transmitted to the opposite end, the recovered electric signal is sent to the Receiver, the Receiver is another functional chip defined by the invention, the electric signal recovered by the PIN can be amplified (TIA), after the high-speed serial digital signal is recovered, the deserialization is carried out, and the interface is connected with the host side SOC through the MIPI D-PHY interface, so that the transmission of MIPI video is completed. Compared with the traditional PHY layer technology, the method has the advantages that the transmission rate is higher, the transmission distance is longer, the delay is greatly reduced, and the safety is improved.

In another possible application scenario, the method may further include implementing the optical fiber video data transmission of the camera by using the on-chip O-PHY mode, referring to fig. 5, fig. 5 is a schematic diagram of implementing the optical fiber video data transmission by using the on-chip O-PHY mode provided by the present invention.

The bridge-type optical fiber transmission camera implemented in fig. 4 uses a C/D-PHY, mainly because the main stream chips of the current camera and screen come from the mobile phone industry, so the interface form defined by the MIPI organization is naturally used, and with the application popularization of the internet of things and the intelligent automobile in the future, the future serialization Deserializer function (Serialize/Deserializer) can be integrated into the CIS and the host side SOC chip respectively, and through the general high-speed SerDes transmission, the Transmitter and Receiver functions only need to realize the DRV and TIA functions, and the general optical module device in the communication industry can be selected.

Therefore, in fig. 5, the future camera CIS processor chip and the host side SOC chip can implement serialization and deserialization processing by using the general high-speed SerDes (currently, the main-stream high-speed communication interfaces, such as PCIe, USB, rapid-IO, FC interfaces all tend to use the general SerDes interface as the PHY layer transmission technology, and the main-stream semiconductor companies all have the general high-speed SerDes technology, which can support docking of different manufacturers and maturation of industrial chains), so that the C/D-PHY function module between two chips (between the Transmitter and CIS/between the Receiver and SOC) is omitted, and the cost and the power consumption are better. The other DRV, TIA, PIN, VCSEL devices can be mature devices in the communication industry. Meanwhile, the devices can select device combinations with different performances according to different speed requirements and different transmission distances.

In another possible application scenario, the system further comprises a data transmission device for transmitting data between the SOC and the display screen, and the structure schematic diagram is shown in fig. 6 and fig. 7. Fig. 6 may correspond to fig. 4, and fig. 7 may correspond to fig. 5, in which video data transmission between the host and the screen is implemented by a built-in O-PHY.

The data transmission mode between the host and the display screen is similar to the data transmission scene applied between the camera and the host, and the difference is that:

1. when the display screen is applied, the MIPI interface direction is output from the host to the screen, so that the direction is opposite to that of the camera when the display screen is applied, the display screen is used as a transmitting end on the host side, and the display screen is used as a receiving end on the screen side.

2. In screen applications, the cable does not include the functionality of a screen, but merely provides a standard C/D-PHY interface to interface with the screen.

3. In screen application, the configuration management channel is the same as the high-speed video transmission direction, so that an out-of-band CCI channel is not needed. Control management information is integrated internally in MIPI C/D-PHY.

4. When the screen is applied, the power supply channel is optional, and the power supply channel and the optical fiber can form a photoelectric composite cable together, and can supply power independently.

It can be appreciated that, based on the defects in the background art, the optical fiber-based data transmission device provided by the invention comprises: the Transmitter chip is connected with the laser deserializing module sequentially through the laser transmitting module, the multimode optical fiber, the laser receiving module and the Receiver; compared with the prior art, the beneficial effects are as follows: the invention provides a PHY layer solution based on optical transmission, which has higher transmission rate (6G is improved to 10G) and longer transmission distance (15 m is improved to 100 m) compared with the PHY layer technologies such as C/D/A-PHY, LVDS, USB and the like; compared with the existing copper wire transmission scheme, the method has the advantages that the power consumption is lower, EMC interference is avoided, the used data threshold is greatly reduced, the time delay of data transmission is reduced, and the safety of data is improved.
