For Digital Cameras
FEATURES DESCRIPTION в—Џ CCD SIGNAL PROCESSING:
Correlated Double Sampling (CDS)
Programmable Black Level Clamping The VSP2212 is a complete mixed-signal processing
IC for digital cameras, providing 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 video information from the pixels, –6dB to +42dB 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 input CDS is also performed. The stable gain
control is linear in dB. Additionally, the black level is
quickly recovered after gain change. The two on-chip
general-purpose 8-bit digital-to-analog converters allow you to obtain analog various control voltage, such
as VSUB control of CCD imager. The VSP2212 is the
high-performance version of the VSP2000/2100 families. The VSP2212Y is available in an LQFP-48 package and the VSP2212M is avail able in a VQFN-48
package. Both products operate from a single +3V/
+3.3V supply. в—Џ PROGRAMMABLE GAIN AMPLIFIER (PGA):
–6 to +42dB Gain Ranging
