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:

Input clamp circuitry and a CDS

Programmable gain amplifier (PGA) with 0-dB to 36-dB gain range (0.047 dB/step) for CCD mode, 0-dB

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

Internal programmable optical black level and offset calibration

10-bit, 21 MSPS pipeline ADC for CCD mode and 28 MSPS ADC for video mode

Paralleldata port for easy microprocessor interface and a serial port for configuring internal control registers

Two DACs for external system control

Internal reference voltages

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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
