DESCRIPTION
The VSP2100Y is a complete digital camera IC, pro-
viding 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 ranging with digital control
for varying illumination conditions, and black level
clamping for an accurate black reference.
Input signal clamping and offset correction of the CDS
is also performed. The stable gain control is linear in
dB. Additionally, the black level is quickly recovered
after gain change. An on-chip general purpose 10-bit
digital-to-analog converter allows you to obtain ana-
log control voltage for iris control.
The VSP2100Y is available in a 48-lead LQFP pack-
age and operates from a single +3V supply.
