VSP2230  
SLAS319 – MAY 2001  
CCD SIGNAL PROCESSOR  
FOR DIGITAL CAMERAS  
FEATURES  
DESCRIPTION  
D
CCD Signal Processing  
– Correlated Double Sampling (CDS)  
– Programmable Black Level Clamping  
TheVSP2230isacompletemixed-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, a6-dBto42-dBgainwithdigitalcontrol  
for varying illumination conditions, and black level  
clamping for an accurate black level reference.  
D
D
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  
D
D
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: 120 mW (typ) at 3.0 V  
– Standby Mode: 6 mW  
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.
