| OV7725 VGA product brief high performance, all-digital VGA camera solution available in a lead-free package The OV7725 CameraChipTM sensor is a highperformance 1/4 inch, single-chip VGA camera and image processor in a small footprint package. Operating at full functionality, the OV7725 meets all pc multimedia and cameraphone market requirements in terms of performance, quality and reliability. The lowpower OV7725 excels in low light conditions and can operate in a wide temperature range, from -20C to +70C. The OV7725 incorporates a 640 x 480 image array, capable of operating at 60 frames per second in VGA mode with complete user control over image quality, formatting and output data transfer. The OV7725 provides full-frame, sub-sampled or windowed 8-bit/10-bit images in a wide range of formats, controlled through the serial camera control bus (SCCB) interface. The OV7725 possesses all required camera processing functions including exposure control, gamma, white balance, color saturation, hue control and more. These functions are also programmable through the SCCB interface. applications camera phones toys digital still cameras webcams OV7725 ordering information OV07725-VL1A (color, lead-free, CSP2-28) (color, no chip probing, no backgrinding) OV07725-G00A product features high sensitivity for low-light operation standard SCCB interface output support for: frame synchronization capability automatic image control functions including: product specifications array size: 640 x 480 power supply analog: 3.0V to 3.6V digital core: 1.8 VDC 10% I/O: 1.7V to 3.3V active: 120 mW (60 fps VGA, YUV) standby: <20 A 3984 m x 2952 m up to 510:1 (for selected fps) dynamic range: 60 dB pixel size: 6.0 m x 6.0 m lens size: 1/4" scan mode: progressive fixed pattern noise: < 0.03% of V PEAK-TO-PEAK CSP2: 5345 m x 5265 m COB: 5360 m x 5260 m -20oC to +70oC - raw RGB - RGB (GRB 4:2:2, RGB565/555/ 444) - YCbCr (4:2:2) formats supports image sizes: VGA, QVGA, and any size scaling down from CIF to 40x30 VarioPixel(R) method for sub sampling edge enhancement level auto adjust noise suppression technology auto adjust - automatic exposure control (AEC) - automatic gain control (AGC) - automatic white balance (AWB) - automatic band filter (ABF) - automatic black-level calibration (ABLC) power requirements image area: package dimensions: image quality controls including color saturation, hue, gamma, sharpness (edge enhancement), and anti blooming electronic exposure S/N ratio: 50 dB temperature range functional block diagram column sense amp row select analog processing G R B buffer A/D DSP* buffer image array image scaler FIFO video port D[9:0] exposure/ gain detect test pattern generator registers clock video timing generator exposure/gain control SCCB interface HREF RSTB XCLK PCLK VSYNC note 1 DSP* (lens shading correction, de-noise, white/black pixel correction, auto white balance, etc.) PWDN FSIN SDA SCL 7725_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. `OmniVision', the OmniVision logo, `VarioPixel', and `OmniPixel' are registered trademarks of OmniVision Technology.
