The CDS extracts the pixel video information from the CCD signal, and the analog-to-digital converter (ADC) converts the digital signal. For varying illumination conditions, a very stable gain control of –9 dB to 44 dB is provided. The gain control is linear in dB. Input signal clamping and offset correction of the input CDS are also provided. Offset correction is performed by the optical black (OB) level calibration loop, and is held in calibrated black level clamping for an accurate black level reference. Additionally, the black level is quickly recovered after gain changes. The VSP2560/62/66 are available in LQFP-48 packages and operate from single +3 V supplies. Table 1.
