† 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 VSP1021 device is a highly-integrated monolithic analog-signal processor/digitizer designed to interface the area charge-coupled-device (CCD) sensors in digital-camera and camcorder applications. The VSP1021 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 ADC. The key components of the VSP1021 device include:
Input clamp circuitry and a correlated double sampler (CDS)
Programmable-gain amplifier (PGA) with 0-dB to 36-dB gain range for CCD mode and 0-dB to 12-dB range for video mode
Two internal DACs for automatic or programmable optical-black-level and offset calibration
10-bit, 25-MSPS pipeline ADC for CCD mode and a 28-MSPS ADC for video mode
Parallel data port for easy microprocessor interface and a serial port for configuring internal control registers
Two additional DACs for external system control
Internal reference voltages

The VSP1021 device is designed using advanced CMOS process and operates from a single 3-V power supply with a normal power consumption of just 95 mW, and 1 mW in power-down mode.

High throughput rate, single 3-V operation, very-low-power consumption, and fully-integrated analogprocessing circuitry make the VSP1021 device an ideal CCD and video-signal-processing solution for electronic video-camcorder applications.

This device is available in a 48-terminal TQFP package and is specified over an operating temperature range of 20°C to 75°C.
