AN5385K

Contour correction IC

■ Overview

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.

■ Features

•

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

■ Applications

•

Color TV, wide TV
