Sander CAM-C3188A electronIC Sept. 2004 1/3 ” Color Camera Module with Digital Output The CAM-C3188A is a 1/3” color camera module with digital output. It uses OmniVision ’s CMOS image sensor Ov7620. Combining CMOS technology together with an easy to use digital interface makes CAM-C3188A a low cost solution for higher quality video image application. The digital video port supplies a continuous 8/16 bit-wide image data stream. All camera functions,such as exposure, gamma,gain,white balance,color matrix,windowing,are programmable through Specification Imager Pixels Array Size Pixel size Scanning 8/16 bit video data Data format A/D converter Synchronization Effective image area Exposure Electronic Exposure Gamma Correction S/N Ratio Min Illumination Operation Voltage Operation Current Lens (Optional) Size Interface Image enhancement Applications OV7620, CMOS image sensor 326688 pixels, VGA/CIF Video Conferencing 664 × 492 pixels PC Multimedia 7.6 × 7.6 µm Video Phone Progressive / interlace Video Mail CCIR601, CCIR656, ZV port Still Image -YCrCb 4:2:2, GRB 4:2:2, RGB Machine Vision Built in 10bit 2 ch A/D converter Process control Internal / external 4.86mm × 3.64mm Frame exposure / line exposure option Electronic exposure / Gain / White balance control 500:1 128 curve settings >48dB 2.5Lux, F1.4 5 VDC 120mW Active / 10µW Standby f6mm, F1.6 40 mm x 28 mm I2C interface brightness, contrast, gamma, saturation, sharpness, window, etc. Monochrome composite video signal output 50Hz Pin Description 1–8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 –30 31 32 Y0 – Y7 PWDN RST SDA FODD SCL HREF AGND VSYN AGND PCLK EXCLK VCC AGND VCC UV0 – UV7 GND VTO Digital output Y Bus Power down mode Reset I2C Serial data Odd Field flag I2C Serial clock input Horizontal window reference output Analog Ground Vertical Sync output Analog Ground Pixel clock output External clock input (remove crystal) Power Supply 5VDC Analog Ground Power Supply 5VDC Digital output UV bus Common Ground Video Analog Output (75 Ohm monochrome) PCB Layout (Top view) For programming see OV7620 datasheet
