VSP2264GSJ [Texas Instruments]

The VSP2264 is a complete mixed-signal IC for CCD signal processing with a CCD timing generator and A/D converter. It supports all signal terminals that the CCD and the vertical driver require. The R driver and H driver synchronize the A/D converter clock phase to realize ideal performance. The CCD channel has correlated double sampling (CDS) to extract image information from the CCD output signal. The digital control gain curve is linear in dB, ranging from –6 dB to 42 dB. A black-level clamping circuit ensures black reference level accuracy and speeds black-level recovery after a gain change. Input signal clamping with a CDS offset adjustment function is available.
