DESCRIPTION  
The VSP1221 is a highly-integrated mixed-signal IC  
used for signal conditioning and analog-to-digital  
conversion at the output of a CCD array. The IC has  
a correlated double sampler (CDS) and an analog  
programmable-gain amplifier (PGA) stage followed by  
an analog-to-digital converter (ADC) and a digital  
PGA stage. The CDS is used to sample the CCD  
signal and is followed by the analog PGA stage. The  
ADC is a12-bit, 21-MSPS pipelined ADC. The digital  
PGA provides further amplification.  
Additionally, there is an offset calibration loop for  
optical-black correction. The optical-black reference  
level is user-programmable. The chip also has two  
8-bit digital-to-analog converters (DAC) for external  
analog settings.  
The chip has a serial port for configuring internal  
control registers.  
The VSP1221 is available in a 48-pin TQFP package  
and operates from a single 3-V power supply.
