The primary CCD channel provides Correlated Double Sampling (CDS) to extract video information from the pixels, –6dB to +42dB gain ranging with digital control for varying illumination conditions, and black level clamping for an accurate black reference. Input signal clamping and offset correction of the input CDS is also performed. The stable gain control is linear in dB. Additionally, the black level is quickly recovered after gain change. The two on-chip general-purpose 8-bit digital-to-analog converters allow you to obtain analog various control voltage, such as VSUB control of CCD imager. The VSP2212 is the high-performance version of the VSP2000/2100 families. The VSP2212Y is available in an LQFP-48 package and the VSP22...
