Box 17847, Austin, Texas 78760 (512) 445 7222 FAX: (512) 445 7581 http://www.crystal.com CS7666 Digital Color-Space Processor for CCD Cameras Features l ITU-601 Compliant Image Formatting l ITU-656 and SMPTE-125/M Transport l Provides Separate HREF and VREF (or alternately HSYNC and VSYNC) Signals l I2C Control Interface l Limited Secondary I2C Bus Master l Automatic White Balance l Programmable Gamma Correction l Programmable Interpolation l Programmable Luma Gain and Saturation Control l Fully Programmable Color Separation Matrix Coefficients l Supports up to 1440, active pixels per line, with no limitation on Vertical Size l Pin and software compatible with the CS7665 l Programmable "Color Killer" circuit l Highly integrated for low part count cameras Description The CS7666 is a low-power Digital Color-Space Proces- sor for CCD cameras. It provides all necessary digital image processing for standard four-color interline trans- fer CCD imagers. The CS7666 processes the magenta, yellow, cyan, and green (MYCG) CCD imager data into YCrCb formatted component digital video. Internal pro- cessing includes color separation, automatic white balance, user programmable gamma correction, pro- grammable scaling (interpolation), and output formatting. Also, a special "Color Killer" circuit eliminates false colors during saturation. The digital output of the CS7666 can be configured to comply with the ITU-601, ITU-656 and SMPTE-125/M standards. Additionally, HREF and VREF (or HSYNC and VSYNC) output pins are provided to support older analog video encoders and the current ZV-Port definition. The CS7666 is designed to work directly with the CS7615 CCD Imager Analog Processor, and is a drop in replacement for the CS7665.
