DESCRIPTION
The VSP2230 is a complete mixed-signal processing IC
for digital cameras that provides signal conditioning and
analog-to-digital conversion for the output of a CCD
array. The primary CCD channel provides correlated
double sampling (CDS) to extract the video information
from the pixels, a –6-dB to 42-dB gain with digital control
for varying illumination conditions, and black level
clamping for an accurate black level reference.
Input signal clamping and offset correction of the input
CDS is also performed. The stable gain control is linear
in dB. Additionally, the black level is quickly recovered
after gain change.
The VSP2230Y is pin-to-pin compatible with the
VSP2260Y (10 bit, 20 MHz) one-chip product.
The VSP2230Y is available in a 48-pin LQFP package
and operates from a single 3-V/3.3-V supply.
