OV7949

OV7949 NTSC/PAL product brief high-performance security CameraChip sensor available in a lead-free package The OV7949 CameraChip™ sensor is known as one of the most highly integrated true video NTSC/PAL camera systems. With high functionality and proven excellence in extreme low light settings, the OV7949 image sensor can compete head-to-head with the highly competitive CCD segment of the security surveillance market. With an ever growing security surveillance camera market, the OV7949 image sensor is the most cost efficient solution for applications requiring a high performance video camera with a small footprint, low voltage, low power consumption and high performance. The OV7949 excels in low light conditions and can operate within a wide temperature range from -20°C to +70°C. Key features of the 1/3 inch OV7949 include reduced blooming/smearing effects, and a Genlock function, which allows the synchronization of two or more video sources. This enables the development of very affordable closed-circuit security monitoring systems that are very easy to set up, making the OV7949 a very suitable product for consumer and small business solutions. The OV7949 supports NTSC/PAL composite video output and can directly interface with a TV monitor or another device with 75 Ohm loading. These features and functions of the OV7949 make it a strong solution for any surveillance camera application. applications security/surveillance cameras video conferencing video phones video e-mail toys fingerprint equipment medical and dental equipment OV7949 ordering information OV07949-C10A OV07449-C10A (color, NTSC CLCC-48) (b&w, NTSC CLCC-48) OV07949-C20A (color, PAL CLCC-48) (b&w, PAL CLCC-48) OV07449-C20A product features OmniPixel2 ™ technology single chip 1/3” format video camera composite video (NTSC/PAL) differential output drive sensitivity boost (+42 dB) automatic exposure/gain with 16-zone control auto white balance control aperture/gamma correction 50/60 Hz flicker cancellation external frame sync capability (Genlock) SPI/EEPROM used to control overlay and set other customer variables I2C compatible serial camera control bus (SCCB) control interface for register programming low power consumption extremely low dark current for high temperature applications defective pixel correction product specifications array size: PAL: 628 x 586 NTSC: 510 x 496 analog/ADC/10: 3.3 VDC ± 5% digital core: 1.8 VDC ± 5% 168 mW (DVDD=1.8V. all other voltages=3.3V. 75 Ω loading 5.961 mm x 4.276 mm -20°C to +70°C sensitivity: 4.6V/Lux-sec @ 5600K power supply: S/N ratio: 48 dB (max) dynamic range: 50 dB pixel size: 9.2 μm x 7.2 μm dark current: 70 mW/s @60°C fixed pattern noise: 0.079% of V PEAK TO PEAK 14.22 mm x 14.22 mm power consumption: image area: package dimensions: temperature range: exposure time range: 1/60 s - 12 μs (NTSC) 1/50 s - 12.5 μs (PAL) functional block diagram +CVO column sample/hold row select AMP ADC DSP overlay video encoder DAC -CVO image array gain control DSP control overlay control video encoder control CS SPI interface SCK ESO ESI timing/clock generator register bank SCCB interface CS0* CS1* FSI PAL* FSO XCLK1 XCLK2 SIO_C PWDN SIO_D 7949_PB_001 1341 Orleans Drive Sunnyvale, CA 94089 tel: +1 408 542 3000 fax: +1 408 542 3001 www.ovt.com OmniVision reserves the right to make changes to their products or to discontinue any product or service without further notice.
