Box 17847, Austin, Texas 78760 (512) 445 7222 FAX: (512) 445 7581 http://www.cirrus.com CS7620 CCD Imager Analog Processor Features l 13-Bit A/D Conversion Using DRX™ Technology l Backlight Compensation l Supports three Input Ranges of 0.53V, 1.07V, and 1.60V l Multi-Sync CCD Timing Generator l High Resolution Output Mode l Low Resolution (Preview) Output Mode for LCD Driver l Integrated Correlated Double Sampler l Digital Black Level Clamp l Digital Outputs Selectable for 13, 12, or 10 Bits l Two Integrated General Purpose DACs l Low Power Consumption l Power Down Mode l High Speed Serial Interface l Supports a Large Variety of Clock Input Frequencies l Low power mode option Description The CS7620 is a low-power analog front-end processor for interline or frame transfer CCD imagers. Main appli- cations include digital still image cameras with up to 8k×8k pixels. The architecture includes a correlated double sampler, black level clamp and a 13-bit A/D conversion module using patented DRX technology. In addition, the chip contains a timing generator, which supports common CCDs from IBM, and Polaroid. For CCDs using different timing signals, the internal timing generator can be bypassed. There are 2 general purpose DACs available which can be used to drive motors for iris and shutter control. Chip parameters can be programmed using a high speed 4-wire asynchronous digital interface. The chip outputs digitized CCD data in either 13-bit, 12- bit or 10-bit format. 10-bit outputs are generated from the 13-bit A/D output by a programmable companding curve.
