The MIPI/CSI-2 module, including its serializer, connects to an embedded system (such as NVIDIA Jetson) via FPD-Link III with a maximum cable length of 15 meters. This setup is particularly relevant for applications requiring longer cable runs while maintaining high data transmission quality.

What Is MIPI/CSI-2?

MIPI/CSI-2 refers to the Camera Serial Interface 2 (CSI-2), developed by the Mobile Industry Processor Interface Alliance—a global organization with over 250 companies. This alliance specializes in standardizing interfaces for mobile devices, including camera-related protocols like CSI-2 and display interfaces such as Display Serial Interface 2 (DSI-2). Their focus is on enabling multiple interfaces to operate efficiently within a single physical layer.

The widespread adoption of MIPI/CSI-2 can be attributed to several factors. First, System-on-Chips (SoCs) derived from smartphones are increasingly available in industrial variants, often including CSI-2 by default. Second, components based on MIPI standards are known for their robustness, cost-effectiveness, and energy efficiency.

MIPI/CSI-2 for Vision Applications

Modern SoCs with MIPI/CSI-2 inputs incorporate hardware-accelerated image preprocessing features via an Image Signal Processor (ISP). The ISP handles tasks such as demosaicing, color correction, or even complex operations like H.264/H.265 encoding and distortion correction. This capability allows for compact camera designs while leveraging the SoC’s processing power.

The automotive industry is a significant driver of MIPI/CSI-2 adoption today. Components like infotainment systems increasingly rely on these protocols to transmit high-quality video data over longer distances, supporting features such as digital rear-view mirrors and surround-view cameras.

The 15-Meter Cable Advantage

One challenge in extending cable lengths for camera modules is the limitation of standard ribbon cables (typically under 30 cm). FPD-Link III from Texas Instruments addresses this by offering high-resolution video transmission alongside bidirectional control channels. These systems use a single coaxial cable, which is thin, flexible, and cost-effective—ideal for automotive and industrial applications.

To transmit MIPI/CSI-2 signals via FPD-Link III, two components are needed: a serializer (converting from MIPI/CSI-2 to FPD-Link III) placed on the camera module side, and a deserializer (converting back). This setup ensures seamless transmission without interrupting the user experience.

Summary

The Imaging Source now provides FPD-Link III bridges for embedded systems like NVIDIA Jetson. These modules enable MIPI/CSI-2 signals to be transmitted reliably over longer distances—up to 15 meters—while maintaining high performance and cost-efficiency.
