VV5300

VV5300 Sensor Integrated CMOS Image Sensor with on-chip ADC. DISTINCTIVE CHARACTERISTICS Standard image format: 160 x 120 164 x 124 pixel array Variable frame rate (2 fps - 60 fps) On-chip 8-bit A/D convertor 8-bit and 4-bit conversion modes 8-wire and 4-wire parallel data output modes Options selectable via serial interface Automatic black level calibration Automatic exposure and gain controller 2 serial data output modes Reduced flicker operation with 50Hz and 60Hz mains frequencies GENERAL DESCRIPTION VV5300 is a highly-integrated CMOS image sensing device. In addition to a 160 x 120 pixel image sensor array, the device includes on-chip circuitry to drive and sense the array. The primary image size is 160 x 120 but border pixels/lines can be enabled to give an effective image size of 164 x 124. BLOCK DIAGRAM Pr Pixel Resolution Pixel Size SDA SCL el im DIGITAL CONTROL LOGIC D[7:0] IMAGE FORMAT SIN FST QCK The output stage of the sensor contains a successive approximation circuit which performs analogue-todigital conversion of the photodiode array to produce 8-bit or 4-bit pixel data. in VV5300 features electronic exposure and gain control over a wide range, enabling the use of a single fixed-aperture lens. A bi-directional 2-wire serial communications interface allows the device to be configured and its operating status monitored. The status information may also be multiplexed onto the digital output bus. ar Array Size Power Supply Min.illumi...
