APPLICATIONS
D DSC, DVC, Security Camera
The VSP2270 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 VSP2270Y device is available in a 48-lead LQFP
package and the VSP2270M device is available in a
48-lead P-VQFN package. Both devices operate from
a single 3-V/3.3-V supply.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
