VSP2272Y 适用于 CCD 传感器的 12 位 28MSPS 单通道 AFE
DESCRIPTION
The VSP2272 device is a complete mixed-signal
processing IC for digital cameras providing signal
conditioning and analog-to-digital conversion for the
output of a charge-coupled device (CCD) array. The
primary CCD channel provides correlated double
sampling (CDS) to extract the video information from
the pixels, –6-dB to 42-dB gain range 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
are also performed. The stable gain control is linear in
dB. Additionally, the black level is quickly recovered
after gain change.
The VSP2272Y device is available in a 48-lead LQFP
package and the VSP2272M device is available in a
48-lead P-VQFN package. Both devices operate from
a single 3-V/3.3-V supply.
