† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

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
Parallel data 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.
