The AN5385K is an IC which conducts contour
correction for luminance signal and color difference signal. It corresponds to all broadcasting systems of PAL, NTSC and SECAM. Fewer external
parts enables the TV sets to be less cost and high
picture quality.
• Black side contour emphasis and white side shoot
elimination circuit are built in (for anti-blooming)
• Transient correction of color difference signal
(color missing improvement)
• Red gamma correction circuit built in
• Wider band of signal processing (Y: 7 MHz/−3
dB, Color difference: 3 MHz/−3 dB)
• Delay time is identical for both Y and color
difference.
• Delay amount switch is built in
• Delay line and coupling condenser built in
