VGA resolution USB2.0 web camera sensor
The VL6522 is a VGA imager on chip (IOC), fabricated in a high performance 0.18 μm CMOS imaging process. The device produces a YUV 4:2:2 digital video data stream at up to 60(a) frames per second, and supports a microphone input.
Video and audio data is output via a USB2.0 high speed (480 Mbps) interface and allows simple interfacing to a host PC using generic audio and video class drivers under the appropriate operating system (Windows XP). Audio/video class compliance and vendor command sets allow development of other O/S drivers with relative ease
