LVDS internal interconnect optimization: High-performance signal cable solution

In modern electronic devices, the speed and stability of signal transmission directly affect the overall performance of the entire machine. LVDS (Low Voltage Differential Signal) remains the mainstream method for internal high-speed transmission in display modules, vehicle-mounted systems, and industrial cameras, etc. With devices becoming increasingly thin, light, and compact, how to ensure signal integrity within a limited space has become a key issue. Extremely thin coaxial cables (micro coaxial cable) have gradually become the focus of engineers due to their excellent high-speed transmission performance and shielding ability.

LVDS signal characteristics

LVDS employs low voltage differential transmission, with paired signal lines effectively canceling out external interference, featuring advantages such as low power consumption, low noise, high speed, and strong anti-interference capability, and is widely used in display panels, camera modules, and industrial vision systems. Its performance highly depends on the cable structure, and impedance mismatch, crosstalk, or signal attenuation can lead to system instability, especially in high-speed and high-density applications, where strict requirements are placed on the wire materials.

The advantages of ultra-fine coaxial beam

Extremely thin coaxial cable bundles consist of conductors, insulating layers, shielding layers, and outer sheaths. Their diameter is extremely small, allowing for high-density wiring in narrow spaces. They have the advantages of independent shielding to reduce interference, precise impedance control to reduce reflections, adaptability to high-frequency and high-speed transmission, and flexibility and compactness for routing in tight spaces. Compared to traditional twisted pairs or FFC ribbon cables, they can significantly improve signal integrity and stability in high-speed, high-density, and strong interference environments.

Is it the optimal solution for LVDS?

The extremely thin coaxial cable bundle is not the only choice for all LVDS applications. Its cost and wiring complexity are higher than that of twisted pair or FFC cables, and it has slightly lower flexibility and higher requirements for the symmetry of the wire pairs. Overall, in applications with high system speeds, strong interference, or limited space, the extremely thin coaxial cable bundle is the best solution; while in scenarios with moderate speeds, low interference, or cost sensitivity, shielded twisted pair or FFC cables still have advantages.

Extremely thin coaxial cable束 performs outstandingly in LVDS high-speed signal transmission, significantly enhancing signal integrity and anti-interference ability under high-frequency, high-speed, strong interference, and space-limited conditions. It is an optimal solution for high-end equipment design. With the thinning of equipment and the increase of signal speed, its application prospects will continue to expand.
