1 ics for tv AN5385K contour correction ic n overview the AN5385K is an ic which conducts contour correction for luminance signal and color differ- ence signal. it corresponds to all broadcasting sys- tems of pal, ntsc and secam. fewer external parts enables the tv sets to be less cost and high picture quality. n 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 n applications color tv, wide tv sync chip clamp pedestal clamp pedestal clamp delay switch correction signal generation, white side shoot erase delay line delay line delay line delay line delay line delay line red gamma correction correction signal generation correction signal generation 15 17 13 21 9 7 5 22 2 3 4 1 6 8 19 10 11 14 ydl ymco ymga pol vsl vga gnd3 gnd2 gnd1 n.c. n.c. y out v out u out ctig v cc1 v cc2 v cc3 12 16 18 20 v in u in y in c-pulse sdip022-p-0300a unit: mm 7.620.25 3 to 15 0.35 +0.10 C 0.05 19.10.3 111 22 12 6.350.30 4.500.25 3.450.25 1.100.25 1.778 0.50.1 0.900.25 seating plane n block diagram
