AN2108NFHQ

Camera Signal Processing(CDS + AGC + Gamma)

■ Overview

The AN2108NFHQ is a single-chip IC that processes video-signal of CCD-camera and has functions of CDS, AGC, pre-knee and pre-aperture circuits. This CDS circuit is capable of high speed sampling of max. 30 MHz to support high-resolution CCD-camera systems (XGA, SXGA, etc.). AGC and OB level(black level) adjustments can be controlled with on-chip 8-bit DAC.

■ Features

• Capable of high speed sampling of max. 30 MHz

• Capable of controlling OB level at the last output stage

• Capable of switching between 2 modes of pre-knee

characteristic

• On-chip DAC(8-it, 15-channel)for adjustment

(11-channels for internal and external outputs)

■ Applications

• Digital still cameras, Camcorders, PC cameras, Moni-

toring cameras, CCD camera modules, CCD digital camera systems
