In high-speed signal transmission applications, differential signals have become the preferred transmission method for precision electronic systems such as displays, camera modules, and medical equipment due to their excellent anti-interference capability and signal integrity. At the same time, with the continuous acceleration of the trend towards slimming and miniaturization of devices, micro coaxial cable (extremely thin coaxial cable) has gradually become an important carrier for differential signal transmission due to its compact structure, high flexibility, and excellent electromagnetic shielding performance.
Then, can ultra-thin coaxial cable束 be used for differential signals? The answer is: absolutely. This article will analyze the advantages and implementation methods of ultra-thin coaxial cable束 in differential signal applications with the I-PEX 20680-060T-01 connector.
Why ultra-fine coaxial cables are suitable for differential signals
Differential signaling is a paired transmission method, where the signal is sent and received through one positive and one negative line, relying on voltage difference to restore information. Compared with single-ended signals, differential transmission has significant advantages in terms of anti-interference, signal integrity, and transmission distance.
Extremely fine coaxial beam structures perfectly meet the core requirements for differential transmission, and their main advantages are as follows:
Excellent shielding performance: Each wire has an independent shielding layer, which can effectively isolate external electromagnetic interference (EMI), enhancing the purity of the signal.
Extremely thin and soft: The wire diameter is usually around 0.3mm, with a small bending radius, suitable for applications with limited installation space or requiring multiple bends.
High impedance consistency: The coaxial structure helps maintain impedance matching between differential signal lines, reducing reflections and signal loss.
Therefore, the use of micro coaxial cable for transmitting differential signals has become an industry trend in camera modules, OLED displays, vehicle central control systems, and industrial control equipment.
I-PEX 20680-060T-01: the ideal connection scheme for differential signals
In ultra-fine coaxial differential signal transmission, the connector performance is also a key factor. The I-PEX 20680-060T-01 is a high-performance micro coaxial connector designed for high-speed differential signals, widely used in high-end equipment thanks to its precise structure and excellent electrical characteristics.
The main features of I-PEX 20680-060T-01 include:
0.4mm pitch, 60Pin high-density design, supports parallel transmission of multi-channel differential signals.
Optimized grounding structure design effectively suppresses EMI and crosstalk.
High insert and withdraw ability, long mechanical life, ensuring stable connection;
Supports various ultra-thin coaxial cable models, flexible assembly, and high reliability.
This model has been widely used in high-definition camera modules, VR/AR devices, vehicle imaging systems, and medical imaging terminals, helping devices achieve higher data transmission rates and signal integrity.
III. The Perfect Combination of Extremely Fine Coaxial Beam and Differential Signal
The facts have proven that extremely thin coaxial cables can fully meet the task of transmitting high-speed differential signals. Their independent shielding structure can effectively reduce external interference, while their high flexibility and high density characteristics allow them to maintain excellent signal stability in application environments with limited space. Paired with high-performance connectors (such as I-PEX 20680-060T-01), extremely thin coaxial differential cables can not only achieve lower signal loss but also significantly improve the system's anti-interference ability and overall electromagnetic compatibility (EMC), thereby satisfying the dual requirements of modern electronic equipment for high bandwidth and high reliability.
In high-speed transmission systems, the combination of extremely thin coaxial cables with differential signals is an ideal solution for miniaturization and high-performance design. The I-PEX 20680-060T-01, with its precise design and stable performance, provides solid support for differential signal transmission. Whether it is for display screens, camera modules, or vehicle and medical imaging equipment, micro coaxial cables continue to demonstrate their irreplaceable advantages.
