CCD SIGNAL PROCESSOR for

DIGITAL CAMERAS

FEATURES

DESCRIPTION

● CCD SIGNAL PROCESSING:

The VSP2260 is a complete mixed-signal processing

IC for digital cameras, providing signal conditioning

and Analog-to-Digital (A/D) conversion for the output

of a CCD array. The primary CCD channel provides

Correlated Double Sampling (CDS) to extract video

information from the pixels, –6dB to +42dB gain

range 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 are also performed. The

stable gain control is linear in dB. Additionally, the

black level is quickly recovered after gain change. The

VSP2260Y is available in an LQFP-48 package and

operates from a single +3V/+3.3V supply.
