description

The VSP10T21 device is a complete charge-coupled device (CCD) and video signal processor/digitizer

designed for digital camera and camcorder applications. The VSP10T21 device performs all the analog

processing functions necessary to maximize the dynamic range, corrects various errors associated with the

CCD sensor, and then digitizes the results with an on-chip high-speed analog-to-digital converter (ADC). One

of the key features of this device is an integrated programmable delay generated for the CDS timing control,

which eases the AFE timing adjustments for optimum image quality. Other key components of the VSP10T21

device include:

to 12-dB gain range (0.047 dB/step) for video mode

Designed in advanced CMOS process, the VSP10T21 device operates from a single power supply with a

normal power consumption of 109 mW at 2.7 V and 21 MSPS and a 1.5-mW power-down mode.

High precision, single 3-V operation, very low power consumption, and fully integrated analog processing

circuitry make the VSP10T21 device an ideal CCD signal processing solution for the electronic video camcorder

and digital still camera applications.

The part is available in a 48-terminal TQFP package and is specified over an operating temperature range of

–20

°C to 75°C.
