The camera module can be miniaturized through CMOS+SERDES encoding chip and USB3.0 chip, and the transmission distance between the camera and the motherboard can be up to 15 meters, which is convenient for deployment on automated equipment and supports data transmission with a maximum bandwidth of 5G.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] Through the above technical solution, the COAX coaxial cable is a cable composed of an inner conductor, an insulating layer, an outer conductor and an outer sheath. Its structure makes the signal less interfered during transmission and can maintain good signal integrity and stability. The COAX coaxial cable is used to connect the encoding module and the decoding module to transmit the encoded serial data signal, which can reduce signal attenuation and interference and is suitable for transmitting high-frequency signals.

[0010] Furthermore, the 5V power supply module is connected to the USB3.0 chip module, and the USB3.0 chip module is connected to the serdes decoding module through two groups of I2C buses and GPIO interfaces;

The SERDES chip encodes the received parallel data and converts it into a serial data stream to ensure reliable data transmission and error detection. The encoded serial data stream is transmitted to the receiving end through a high-speed serial transmission line. After receiving the serial data stream, the SERDES chip at the receiving end decodes it and converts it into a parallel data stream. The decoding process is opposite to the encoding process. The decoding operation is performed by identifying the encoding algorithm. The decoded parallel data stream is output to the target device of the system to complete the data transmission process. In the entire system process, SERDES technology plays a key role in data encoding and decoding and serial / parallel data conversion, realizing the requirements of high-speed data transmission and communication.
