DESCRIPTION
The VSP2230 is a plete mixed-signal processing IC for digital cameras that provides signal conditioning and analog-to-digital conversion for the output of a CCD array. The primary CCD channel provides correlated double sampling (CDS) to extract the video information from the pixels, a
- 6-d B to 42-d B gain with digital control for varying illumination conditions, and black level clamping for an accurate black level reference. Input signal clamping and offset correction of the input CDS is also performed. The stable gain control is linear in d B. Additionally, the black level is quickly recovered...
