CCD Video Camera Signal Processor ICs

AN2145NFHP, AN2146FHP, AN2147FHP CCD Video Camera Signal Processor ICs s 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. The AN2146FHP is for 670H CCD, and the AN2147FHP is for 768HCCD.
