The application and advantages of extremely fine coaxial cables in LVDS high-speed transmission

In modern electronic devices, LVDS (Low Voltage Differential Signal) is widely used in high-speed display and transmission systems such as laptops, tablets, vehicle displays, and industrial cameras. With the development of devices towards high resolution, high-speed transmission, and slimming down, signal integrity and anti-interference performance have become key challenges. Micro coaxial cable, with its precise structure, excellent shielding ability, and high flexibility, is becoming the ideal solution for LVDS high-speed signal transmission.

One、The Structure and Characteristics of Superfine Coaxial Beam

The ultra-fine coaxial cable束 consists of a central conductor, insulating medium, shielding layer, and outer sheath, with a diameter that can be as small as less than 0.3mm. Its coaxial structure ensures excellent electromagnetic shielding performance, reduces crosstalk and signal reflection, while maintaining precise impedance control. The thin and flexible design makes it possible to densely route in confined spaces, suitable for high-speed miniaturized scenarios such as laptops, camera modules, vehicle displays, and medical equipment.

Section 2: Advantages and Challenges of LVDS Signal Transmission

LVDS employs low-voltage differential signaling, featuring low power consumption, high speed, and anti-interference capability. However, reflections, crosstalk, and EMI interference in high-speed environments still easily affect signal quality, especially inside compact devices. Traditional ribbon cables find it difficult to balance miniaturization and high-speed transmission. The ultra-fine coaxial cable bundle, with its precise impedance, independent shielding, and low loss characteristics, effectively solves the stability problem of LVDS signals in high-speed transmission.

Section 3: Application Advantages and Design Key Points

Extremely fine coaxial cable bundles have significant advantages in LVDS applications: high shielding ensures signal integrity, low impedance loss supports high-speed transmission, and mechanical flexibility and high bend life accommodate thin and vibration environments. In design, attention should be paid to impedance matching, length consistency, shielding grounding, routing optimization, and connector matching to ensure stable and efficient transmission of multi-channel LVDS signals. Typical applications include notebook and tablet display modules, in-vehicle display and image systems, as well as high-speed data collection and image transmission for industrial and medical equipment.
