AN2108NFHQ
Camera Signal Processing(CDS + AGC + Gamma)
■ Overview
Unit : mm
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.
