| 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 OmniPixel2TM 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. applications medical and dental equipment security and surveillance toys and games OV6920 ordering information OV06920-V09A (color, NTSC, 9-pin CSP2) product features single chip 1/18" NTSC lens video camera composite video output automatic exposure/gain/white balance aperture correction gamma correction low power consumption +3.3V only power supply wide dynamic range, anti=blooming, zero smearing SCCB programmable controls: - - - - color saturation exposure gain gamma curve product specifications array size: - total: 328 x 250 - active (NTSC): 320 x 240 optical size: 1/18" color mosaic: RGB Bayer pattern sensitivity: 0.7V(Lux-sec) S/N ratio: 42 dB dynamic range: 42 dB pixel size: 2.5 m x 2..5 m dark current: 3 mV/sec image area: 820 m x 625 m package dimensions: 2135 m x 2265 m power supply: 3.3VDC 5% power requirements: - without loading: 20 mA - with 75 ohm loading: 30 mA temperature range: - operating: 0C to 50C electronic exposure: 1/60s to 5.7 s output format: composite video functional block diagram +CVO column sample/hold row select AMP analog/digital signal processor image array gain control analog/digital signal control clock/timing generator and control logic control register bank SCCB interface XCLK1 XCLK2 SIO_C SIO_D 6920_PB_001 4275 Burton Drive Santa Clara, CA 95054 tel: +1 408 567 3000 fax: +1 408 567 3001 www.ovt.com OmniVision reserves the right to make changes to their products or to discontinue any product or service without further notice.
