10-Bit, 36Msps CCD Signal Processor For Digital Cameras
The VSP2230 is a complete Mixed-Signal processing IC for digital cameras that provides Signal Conditioning and Analog-to-digital conversion for the output of a CCD array. The primary CCD channel provides correlated double sampling (CDS) to extract the Video information from the pixels, a 6-dB to 42-dB gain 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 is also performed. The stable gain control is linear in dB. Additionally, the black level is quickly recovered after gain change.
The VSP2230Y is pin-to-pin compatible with the VSP2260Y (10 bit, 20 MHz) one-chip product.
The VSP2230Y is available in a 48-pin LQFP package and operates from a single 3-V/3.3-V supply.
