description

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:

for video mode

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 analog-

processing 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.
