| OV7950 NTSC product brief available in a lead-free package ultra-compact, high-performance automotive CameraChipTM sensor The OV7950 is a highly integrated CMOS video camera that packs a high level of functionality. It is the new generation of advanced CMOS image sensors developed specifically for automotive applications, performing exceptionally well in low light conditions (<0.01 lux) and in a wide temperature range from -40 to 105C. At only 1/4-inch square and using only one 3.3 volt DC power supply, the OV7950 color sensor is ideal for applications requiring a small footprint, low power consumption, high-performance video camera. The OV7950 supports NTSC composite video output and can directly interface with an in-car LCD screen or other device with 75 Ohm loading. Key features of the OV7950 include a new windowing feature which allows customers to adjust their camera setup by moving the sensitive area of the camera in either vertical or horizontal directions. This feature is especially useful in fine tuning the viewing window and angle of fixed position cameras, for example cameras mounted in places where there is a chance of obstructed view such as car bumpers. The OV7950 image sensor is particularly well suited to automotive applications because it features a dual static overlay function allowing for both a dynamic and a static visual aid layer (text or graphics) within the image. This is especially useful for reference frames and guiding systems in backup and parking assist cameras for cars and trucks. The OV7950 has completed all required AEC-Q100 Grade 2 qualifications. applications occupant sensor adaptive cruise control rear view/backup camera lane departure warning blind spot detection night vision OV7950 ordering information OV07950-F48V OV07451-F48V (color, NTSC - QFP2-48) (b&w with microlens, NTSC - QFP2-48) product features OmniPixel2TM technology single chip 1/4" format video camera composite video (NTSC) output high sensitivity automatic exposure/gain with 16 zone control horizontal and vertical windowing capability 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 dual static overlay control master/slave 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 AEC-Q100 Grade 2 qualified product specifications array size: 656 x 492 power supply: - analog/ADC/IO: 3.3VDC 5% - digital core: 1.8 VDC 5% optical format: 1/4" sensitivity: 3.0 V/(Lux-sec) @ 5600K S/N ratio: 48 dB dynamic range: 60 dB pixel size: 6.0 m x 6.0 m dark current: 10 mV/s @ 60C fixed pattern noise: 0.22% of V PEAK-TO-PEAK image area: 4.080 mm x 3.102 mm package dimensions: 12.00 mm x 12.00 mm power consumption: - operating: 180 mW (typical) - power down: 10 A (typical) temperature range: -40 to 105C exposure time range: - OV7950: 1/60s - 20s - OV7451: 1/30s - 20s output format: composite video (NTSC) functional block diagram OV7950 overlay column sample/hold row select AMP ADC DSP video encoder DAC +CVO image array gain control DSP control overlay control SPI interface CS SCK ESO ESI timing/clock generator register bank SCCB interface XCLK1 XCLK2 PWDN RESET FSIN OVL2 OVLEn VS SIO_C SIO_D CS1* CS0* OV7950_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.
