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 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.
s Features
• Improved color reproduction with 4-channel white
balance
• Built-in high-luminance color-suppression circuit
• Improved S/N ratio at low brightness
