LVDS Automotive Wiring Harness

　　LVDS Automotive Wiring Harness is a low voltage differential signal (LVDS) automotive wiring harness. The following is a detailed introduction to it:

　　Features

　　High-speed transmission: LVDS technology can achieve high-speed data transmission, meeting the transmission requirements of high-speed data in the car, such as camera image data, infotainment system video signals, etc. The transmission rate is usually between 100Mbps and 3.12Gbps.

　　Low power consumption: The differential signal transmission method effectively reduces power consumption compared to single-ended transmission, which helps to improve the energy efficiency of the car and extend the battery life.

　　Strong anti-interference ability: Differential transmission can offset common mode noise and electromagnetic radiation interference, and can provide more reliable signal transmission quality, reduce signal distortion and bit error rate in the complex electromagnetic environment of the car.

　　Convenient wiring: The cable is relatively thin, light, and flexible, which is convenient for wiring in the complex space inside the car, and is also conducive to the lightweight design of the car.

　　High cost-effectiveness: The use of ordinary copper wire materials for transmission is relatively low in cost compared to other high-speed transmission media such as optical fiber, and also reduces the overall manufacturing cost of the car.

　　Application

　　In-vehicle display system: connects the car's central control display, instrument panel display, rear entertainment display, etc. to achieve high-resolution, high-refresh rate image and video data transmission, providing drivers and passengers with a clear and smooth visual experience.

　　In-vehicle camera system: used to connect the in-vehicle camera with the vehicle's image processing unit or driving computer, and quickly and accurately transmit the high-definition video image signal collected by the camera to the processing center to achieve auxiliary driving functions such as reversing image, panoramic image, and adaptive cruise.

　　Infotainment system: transmits audio, video and control signals between the car's audio system, navigation system and other infotainment devices, and supports multimedia playback, navigation map display and other functions.

　　Design and manufacturing points

　　Cable selection: According to the electromagnetic environment, transmission distance and data transmission rate requirements inside the car, select the appropriate cable type and specification, such as twisted pair or coaxial cable with good shielding performance, to ensure signal transmission quality and anti-interference ability.

　　Connector design: Use reliable LVDS connectors to ensure a firm and stable connection with the cable, with good electrical and mechanical properties. At the same time, the waterproof, dustproof, and shockproof characteristics of the connector should be considered to adapt to the use environment of the car.

　　Wiring planning: Reasonably plan the direction and layout of the wiring harness to avoid close contact with other high interference sources (such as engines, motors, etc.), reduce the impact of electromagnetic interference, and facilitate installation, maintenance and replacement.

　　Performance requirements

　　Electrical performance: including low insertion loss, low voltage standing wave ratio, high impedance matching accuracy, etc., to ensure the integrity and stability of the signal during transmission and reduce signal reflection and attenuation.

　　Electromagnetic compatibility: It has good electromagnetic shielding performance, which can not only prevent the electromagnetic radiation generated by itself from interfering with other devices, but also effectively resist external electromagnetic interference to ensure the normal operation of the automotive electronic system.

　　Environmental adaptability: It can work normally under various harsh environmental conditions in which the car is located, such as high temperature, low temperature, humidity, vibration, impact, etc., to ensure the performance and life of the wiring harness.
