Description
The CS7615 is a low-power Analog front-end processor for standard four-color interline transfer CCD imagers. The architecture includes a correlated double sampler, AGC amplifier, black-level clamp, 10-Bit A/D converter, and a complete multi-sync CCD timing generator. The analog CCD imager output can be directly connected to the CS7615 input, which does not require an external buffer amplifier. The pixel data is double sampled for improved noise performance, and gain adjusted prior to being digitized by the A/D converter.
