CCD Video Camera Signal Processor ICs

■ Overview

The AN2145NFHP is a CCD video camera signal
processor IC for 510H CCD. It incorporates full
chroma signal LPFs and horizontal aperture correc­tion circuits. Because carrier-balance is rationalized
and ajustment-free, adjustments and necessary exter­nal components are reduced half in number as com­pared with conventional versions of ours.
