12 Bit, 21 MSPS, Ultra Low Power CCD Signal Processor

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.
