Why It Is Necessary to Use Extremely Fine Coaxial Beams in High-Speed Imaging with OV2311

In today's era of ever-improving high-speed imaging and real-time detection, OmniVision OV2311 is widely used in precision systems such as intelligent robots, eye-tracking, and AR/VR due to its advantages such as high frame rate and high sensitivity. With the continuous increase in sensor resolution and frame rate, the interface bandwidth also increases, which puts higher requirements on the shielding performance, anti-interference ability, and wiring method of the signal transmission cable. To ensure the stability and reliability of the image signal, choosing the appropriate cable structure becomes crucial.

Why OV2311 is more suitable for pairing with extremely thin coaxial cables

During high-speed transmission, if the shielding of the cable bundle is insufficient, the image output of the OV2311 is prone to be affected by electromagnetic noise, resulting in screen jitter, distortion, or random noise points. Micro coaxial cable (extremely thin coaxial cable bundle) has the characteristics of small size, low transmission loss, and strong anti-interference performance, which can realize stable transmission of high-speed signals in compact structures. Its flexible structure is particularly suitable for high-density wiring scenarios between camera modules, miniature sensor heads, and mainboards.

The shielding design determines the stability of high frame rate transmission.

In high-speed image interfaces such as OV2311, shielding performance is crucial. A good grounding method can reduce the impedance of the shielding layer and avoid the formation of "floating shielding" which causes parasitic interference. For high frame rate scenarios, a single-layer shielding may not provide sufficient anti-interference capability, and it is necessary to adopt double-layer or composite shielding when necessary. During wiring, try to avoid interference sources such as power lines and high-frequency circuits, which can further reduce signal crosstalk. In the connector area, it is necessary to ensure that the shielding layer is in continuous contact with the shell, so that the shielding path is complete and uninterrupted, thus maintaining the overall anti-interference effect.

How to improve the signal stability of the OV2311 system

To achieve high-speed and stable transmission for OV2311, in addition to using micro coaxial cable as the main wiring structure, it is also necessary to combine fine grounding design, shielding structure optimization, and reasonable layout planning. For example, maintaining symmetrical routing of the cable harness, avoiding sharp turns, and controlling impedance consistency can all reduce reflection and loss. During the cable harness manufacturing stage, selecting suppliers with mature technology can ensure shielding quality, terminal processing, and harness consistency, thereby effectively improving the overall stability of the system.

The OV2311 has extremely high requirements for the shielding and anti-interference capabilities of the cable in high-speed imaging and real-time interaction scenarios. By reasonably selecting micro coaxial cables, and combining them with scientific grounding methods and shielding designs, noise interference can be significantly reduced, improving the clarity and stability of image transmission. Only the combination of high-quality cables and professional design can fully utilize the performance advantages of the OV2311.
