DESCRIPTION
The VSP2560/62/66 are a family of complete mixedsignal processing ICs for digital cameras that provide
correlated double sampling (CDS) and analog-todigital conversion for the output of CCD arrays. 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.
