VSP2232

SLAS320 – MAY 2001

CCD SIGNAL PROCESSOR

FOR DIGITAL CAMERAS

FEATURES

DESCRIPTION

CCD Signal Processing

– Correlated Double Sampling (CDS)

– Programmable Black Level Clamping

TheVSP2232isacompletemixed-signalprocessingIC

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

fromthepixels, a–6-dBto42-dBgainwithdigitalcontrol

for varying illumination conditions, and black level

clamping for an accurate black level reference.

Programmable Gain Amplifier (PGA)

– –6-dB to 42-dB Gain Ranging

10-Bit Digital Data Output

– Up to 36-MHz Conversion Rate

– No Missing Codes

76-dB Signal-to-Noise Ratio

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.

Portable Operation

– Low Voltage: 2.7 V to 3.6 V

– Low Power: 130 mW (typ) at 3.0 V

– Standby Mode: 6 mW

The VSP2232Y is pin-to-pin compatible with the

VSP2262Y (12-bit 20 MHz) one-chip product.

The VSP2232Y is available in a 48-pin LQFP package

and operates from a single 3-V/3.3-V supply.
