OV6920 NTSC product brief ultra small 1/18-inch CMOS camera-on-a-chip available in a lead-free package The OV6920 is a 1/18-inch optical format CMOS image sensor incorporating a high level of functionality and very low power consumption in an ultra-small footprint package. This makes it ideal for use in small disposable cameras for medical imaging applications such as diagnostic and intubation systems. The 2.1 x 2.3 mm CSP packaged sensor enables a microscopic camera module with a 4.0 mm diameter, to make medical procedures even less invasive for the patient. Having been designed for very low power operation, the OV6920 only requires a clock and a single 3.3-volt DC power supply to get the NTSC composite signal out to a direct interface with a VCR and TV monitor. The OV6920 is built on OmniVision's proprietary OmniPixel2™ architecture providing the highest image quality, performance and clarity. It is an ideal solution for medical applications that require both color video and a very small footprint package.
