OV7740

OV7740 VGA product brief ultra-high sensitivity CMOS image sensor available in a lead-free package The OV7740 (color) CameraChip™ sensor is a low power, high sensitivity VGA CMOS image sensor that provides the full functionality of a single-chip VGA camera in a small footprint. Using OmniVision's proprietary OmniPixel3-HS™ technology, the 1/5-inch OV7740 boasts a best-in-class low light sensitivity of 6800mV/(Lux-sec), making it ideal for integrated notebook cameras, as well as stand-alone PC webcams, security and gaming applications. The OV7740 can operate at 60 frames per second (fps) in VGA resolution and 120 fps in QVGA resolution with complete user control over image quality, formatting and output data transfer. It supports a digital video parallel port, and provides full-frame, sub-sampled, windowed or scaled 8-bit/10-bit RAW RGB and 8-bit YUV images. All required image processing functions including exposure control, gamma, white balance, color saturation, hue control, defective pixel canceling, noise canceling, etc., are programmable through the serial camera control bus (SCCB) interface. In addition, the OV7740 uses proprietary technology to improve image quality by reducing or eliminating common lighting/electrical sources of image contamination, such as fixed pattern noise and smearing, to produce a clean and fully stable color image. For storage purposes, the OV7740 also includes one-time programmable (OTP) memory. applications PC multimedia security/surveillance toys/games OV7740 ordering information OV07740-A32A OV07740-G00A (color, lead-free, 32-pin CSP3) (color, chip probing, no backgrinding) product features support for output formats: RAW RGB and YUV support for image sizes: VGA, QVGA, CIF and any size smaller support for black sun cancellation support for internal and external frame synchronization standard SCCB serial interface digital video port (DVP) parallel output interface embedded one-time programmable (OTP) memory on-chip phase lock loop (PLL) embedded 1.5 V regulator for core product specifications array size: 656 x 488 power supply: – core: 1.5VDC ± 5% – analog: 3.3V ± 5% – I/O: 1.7 ~ 3.47V max image transfer rate: – VGA (640x480): 60 fps – QVGA (320 x 240): 120 fps sensitivity: 6800 mV/(Lux-sec) maximum exposure interval: 502 x tROW pixel size: 4.2 μm x 4.2 μm image area: 2755.2 μm x 2049.6 μm package/die dimensions: – CSP3: 4185 μm x 4345 μm – COB: 4200 μm x 4360 μm temperature range: – operating: -30° C to 70°C – stable image: 0° C to 50° C output format: – 8-/10-bit raw RGB data – 8-bit YUV lens size: 1/5" input clock frequency: 6 ~ 27 MHz functional block diagram OV7740 image sensor core column sample/hold image sensor processor image output interface digital gain black level calibration row select image array AMP 10-bit A/D formatter FIFO DSP DVP DATA[9:0] gain control control register bank SCCB slave interface PLL timing generator and system control logic PWDN HREF VSYNC PCLK XVCLK1 SIOD SIOC SFIN 7740_PB_1 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.
