Technical content

The AN2145NFHP is a CCD video camera signal processor IC for 510H CCD. It incorporates full chroma signal LPFs and horizontal aperture correc- tion circuits. Because carrier-balance is rationalized and ajustment-free, adjustments and necessary exter- nal components are reduced half in number as com- pared with conventional versions of ours. The AN2146FHP is for 670H CCD, and the AN2147FHP is for 768HCCD. n Features

• Improved color reproduction with 4-channel white balance
• Built-in high-luminance color-suppression circuit
• Improved S/N ratio at low brightness AN2145NFHP, AN2146FHP, AN2147FHP CCD Video Camera Signal Processor ICs 12.0–0.2 14.0–0.2 12.0–0.2 14.0–0.2 Unit:mm 80-Pin QFH Package (QFH080-P-1212) (0.5) (min0.25) 1.3–0.1 1.3–0.1 2.8–0.2 0.15– 0.05 + 0.1 0.1–0.1 0.5 0.2 Parameter Symbol Rating Unit V CC ICC PD Topr Tstg 100 357 –20 to +75 –55 to +125 Supply voltage Supply current Power dissipation Note 2) Operating ambient temperature Note 1) Storage temperature Note 1) 5.5 V mW mA Note 1) Ta=25˚C except operating ambient temperature and storage temperatures unless otherwise specified.
