DESCRIPTION
The VSP2000 is a complete digital camera IC, provid-
ing signal conditioning and 10-bit analog-to-digital
conversion for the output of a CCD array. The primary
CCD channel provides correlated double sampling to
extract the video information from the pixels, 0dB to
+34dB gain range with analog control for varying
illumination conditions, and black level clamping for
an accurate black reference. The stable gain control is
linear in dB. Additionally, the black level is quickly
recovered after gain changes. The VSP2000 is avail-
able in a 48-lead LQFP package and operates from a
single +3V supply.
