The best match for the Sony IMX728 image sensor: why it is essential to choose ultra-fine coaxial cable束

With the continuous development of technologies such as intelligent driving, industrial robots, and drones, the demand for 4K-level high-speed image acquisition is constantly increasing. Sony IMX728, as an outstanding image sensor, has been rapidly applied in the fields of vehicle vision, robot vision, and high-end surveillance. However, in the high-speed MIPI CSI-2 transmission link, simply having an excellent sensor module is far from enough; choosing the appropriate MIPI interface cable is particularly crucial. Among them, ultra-fine coaxial cables are gradually becoming the mainstream solution.

Part 1: Technical Background of Sony IMX728 and High-Speed Interface

Sony IMX728 features an 8.39MP 4K resolution and supports MIPI CSI-2 as well as being compatible with GMSL2 and GMSL3 for long-distance video transmission and PoC power supply capabilities. In high-speed transmission systems, the IMX728 outputs large amounts of data at high rates, demanding strict requirements for cabling losses, impedance, and anti-interference capabilities. The extremely fine coaxial cable束 is an interconnect solution specifically designed for high-speed differential signals, which can effectively enhance bandwidth stability and overall system reliability.

Why is IMX728 more suitable for ultra-fine coaxial cable束

Compared with traditional FFC and twisted pair cables, extremely thin coaxial cable bundles provide independent shielding for each signal line, giving them superior EMI interference resistance and more stable impedance control. Within a transmission distance of 15-20cm, they can maintain lower loss and higher eye diagram margin, thus further improving MIPI signal integrity. At the same time, the high flexibility of micro coaxial cables allows for flexible wiring in applications with compact structures and frequent movement, such as robotic arms and drones. In GMSL2/GMSL3 schemes, a single coaxial cable can enable long-distance transmission and support PoC, significantly reducing the number of cables required, which is an important advantage for vehicle and robotic vision systems.

Typical application scenarios demonstration

In vehicle ADAS systems, when paired with GMSL2 and micro coax, the IMX728 achieves a transmission distance of up to ten meters while maintaining stable image quality. In industrial robots, the anti-bending capability of micro coax significantly reduces the risk of wire breakage caused by mechanical motion, ensuring the real-time and reliable nature of visual recognition. In drones and aerial photography equipment, the lightweight and small diameter design of the extremely thin coaxial cable makes it possible to route cables in narrow structures, making it more suitable for lightweight design requirements.

In the high-speed image transmission applications of IMX728, selecting the appropriate cable harness is crucial. Extremely thin coaxial cable harnesses can provide more stable data transmission performance in high-speed, long-distance, and complex installation environments. They are an ideal matching solution for MIPI CSI-2 and GMSL systems and will continue to be the core interconnection method in the fields of vehicle vision, industrial robots, and drones.
