In the field of high-speed data transmission, differential signals are widely used in high-speed camera modules, in-car entertainment systems, industrial automation equipment, and medical electronic instruments due to their excellent anti-interference ability and signal integrity. However, to maintain stable and low-loss transmission performance of differential signals in high-frequency environments, choosing the appropriate transmission medium is particularly crucial. At this point, micro coaxial cable becomes an ideal solution.
Significant structural advantages
The extremely thin coaxial cable consists of an inner conductor, insulating layer, shielding layer, and outer sheath. The inner conductor is coaxially wrapped within the shielding layer.
This design can effectively suppress external electromagnetic interference (EMI) and crosstalk, maintain signal integrity and consistency, and is very suitable for high-speed differential signal transmission in harsh application environments with strict interference requirements.
Two, Precision Impedance Control
Through high-precision manufacturing technology, extremely fine coaxial cables can achieve strict impedance control (commonly differential impedance of 45Ω, 50Ω, etc.).
Ensure perfect matching with system ports, reduce reflection and signal loss, thereby significantly improving the quality of signal transmission.
Transmission loss is lower.
Benefiting from its uniform coaxial structure and excellent shielding characteristics, the micro coaxial cable has the advantages of low insertion loss and low attenuation in high-frequency signal transmission. It can stably support Gbps-level high-speed differential signal transmission, such as MIPI CSI/DSI, USB 3.1, LVDS, HDMI, and other interface standards.
Four, high-density wiring capability
Extremely thin coaxial cables have the minimum outer diameter of 0.3 mm, which can realize high-density routing of multiple signals and still meet the needs of equipment miniaturization and multi-channel high-speed transmission in limited space. This makes it the preferred cable solution for micro-devices such as laptops, tablets, and camera modules. Therefore, extremely thin coaxial cables not only transmit high-speed differential signals but also excel in signal integrity, anti-interference performance, and spatial utilization, becoming an indispensable core component of today's high-speed data transmission systems.
