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
