Here are the typical design problems an Engineer faces when implementing a USB HD camera: The 1080p video requires 1.5 Gbps bandwidth but USB 2.0 provides only 480 Mbps. Therefore USB 2.0 requires compression to reduce bandwidth and compression degrades image quality. Many camera designs require customization to suit specific applications. But dedicated USB camera chips are not programmable. They are fixed function chips for PC webcams. Customers who want to implement advance features or customization simply would not be able to use these fixed function camera chips. As image resolution increases over time, higher resolution image sensors are migrating to a serial interface such as MIPI CSI-2, to keep up with bandwidth requirements. Older parallel interface can no longer keep up with the increase in bandwidth requirements. Large image sensors, typically 5 MP or higher, can use up to four CSI-2 lanes to support the required bandwidth. The CX3 solves all these problems. CX3 is a CSI-2 to USB 3.0 bridge capable of delivering 1080p video without the need for compression. This helps provide much higher video quality compared to that of USB 2.0. The CX3 has an ARM chip (ARM9), and comes with a robust software development kit which provides everything a designer needs for programming to support camera customization. The CX3 provides four CSI-2 lanes and is able to interface with any CSI-2 compliant image sensor or image processor.
