In the daily contact with electronic products, you may often hear the concept of "differential signal. Simply put, it is a common signal transmission method: two wires transmit signals with the same amplitude and opposite phase at the same time, and the receiving end recovers the data by comparing the difference between the two. The advantage of this method is that external noise usually acts on both lines at the same time, and the differential receiver only focuses on the difference between the two, so the influence of interference can be greatly reduced. This is why differential transmission is widely used in high-speed interfaces such as USB, HDMI, and MIPI.

1. differential transmission of the key:

To play a role in differential transmission, it is necessary to ensure the "electrical consistency" of the two wires, that is, the length, impedance, and wiring are as symmetrical as possible. If the asymmetry, it may lead to signal distortion, bit error rate rise, or even direct transmission of high-speed data. Therefore, whether it is PCB design or wiring harness selection, maintaining the consistency of differential pairs is a top priority.

Why 2. choose a very fine coaxial harness?

In compact devices, such as mobile phone camera modules, flat panel displays, and robot joint sensors, it is difficult for conventional FPC or twisted pair to meet the requirements of "high frequency anti-interference small space" at the same time. At this time, the very fine coaxial harness (micro coaxial cable) shows its advantages:

2.1. Self-shielding layer: Each wire has a metal shield, which can effectively reduce crosstalk and external interference.

2.2. Better impedance consistency: The parameters can be strictly controlled during processing, which is more suitable for high-speed differential signals.

2.3, extreme miniaturization: the diameter is usually only 0.3mm ~ 0.5mm, very suitable for small space.

2.4, strong transmission capacity: can support high-speed data links at the GHz level.

This is why very fine coaxial online downstream consumer electronics, medical imaging and industrial automation fields are becoming more and more common.

Examples of 3. applications:

3.1. Image sensor: MIPI differential transmission to ensure clear and high-speed picture.

3.2, medical imaging: low error rate and signal stability requirements are very high.

3.3. Automation equipment: robot joint sensors, high-speed communication in motion control modules.

Differential transmission is a core means to ensure the stability of high-speed signals, and the very fine coaxial wire harness is the "ideal medium" to achieve this way ". In more and more pursuit of thin and high-speed equipment, the combination of the two is gradually becoming the industry trend.
