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 a 12-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 eight-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.
