The VSP2080 is a complete front-end processing IC for digital cameras. The VSP2080 provides signal conditioning for the output of a CCD array. The VSP2080 provides correlated double sampling to extract the video information from the pixels, 0dB to +34dB gain range with analog control for varying illumination conditions, and black level clamping for an accurate black reference. The stable gain control is linear in dB. Additionally, the black level quickly recovers after screen changes. The MODE pin allows the selection of logic-input polarity. The VSP2080 is available in a 20-lead TSSOP package.
