The VSP2262 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 VSP2262Y is a complete mixed-signal processing IC designed for digital cameras. It provides signal conditioning and Analog-to-Digital (A/D) conversion for the output of a CCD array. Key features include Correlated Double Sampling (CDS) to extract video information, a programmable gain amplifier (PGA) with a range of -6dB to +42dB, and a 12-bit digital data output capable of up to 20MHz conversion rates. The device also offers programmable black level clamping and operates from a single +3V/+3.3V supply.
