VSP2000中文资料SpeedPlus™ CCD SIGNAL PROCESSOR FOR DIGITAL CAMERAS数据手册TI规格书

描述 Description

DESCRIPTION
The VSP2000 is a complete digital camera IC, providing signal conditioning and 10-bit analog-to-digital conversion for the output of a CCD array. The primary CCD channel provides correlated double sampling to extract the video information from the pixels, 0dB to +34dB gain range with analog control for varying illumination conditions, and black level clamping for an accurate black reference. The stable gain control is linear in dB. Additionally, the black level is quickly recovered after gain changes. The VSP2000 is available in a 48-lead LQFP package and operates from a single +3V supply.FEATURES
