The VSP2212 is a complete mixed-signal processingIC for digital cameras, providing signal conditioning and analog-to-digital conversion for the output of aCCD array. The primary CCD channel provides CorrelatedDouble Sampling (CDS) to extract video informationfrom 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 correctionof the input CDS is also performed. The stable gain control is linear in dB. Additionally, the black level isquickly recovered after gain change. The two on-chip general-purpose 8-bit digital-to-analog converters allowyou to obtain analog various control voltage, such as VSUB control of CCD imager. The VSP2212 is thehigh-performance version of the VSP2000/2100 families. The VSP2212Y is available in an LQFP-48 packageand the VSP2212M is avail able in a VQFN-48 package. Both products operate from a single +3V/+3.3V supply.
