DESCRIPTION D CCD Signal Processing - Correlated Double Sampling (CDS) The VSP2230 is a complete mixed-signal processing IC - Programmable Black Level Clamping for digital cameras that provides signal conditioning and analog-to-digital conversion for the output of a CCD D Programmable Gain Amplifier (PGA) array. The primary CCD channel provides correlated - -6-dB to 42-dB Gain Ranging double sampling (CDS) to extract the video information D 10-Bit Digital Data Output from the pixels, a -6-dB to 42-dB gain with digital control - Up to 36-MHz Conversion Rate for varying illumination conditions, and black level - No Missing Codes clamping for an accurate black level reference. D 76-dB Signal-to-Noise Ratio Input signal clamping and offset correction of the input D Portable Operation CDS is also performed. The stable gain control is linear - Low Voltage: 2.7 V to 3.6 V in dB. Additionally, the black level is quickly recovered - Low Power: 120 mW (typ) at 3.0 V after gain change. - Standby Mode: 6 mW The VSP2230Y
