TA8748AN

The TA8748AN is for double comb  filter Y/C separation and vertical edge enchancement using the logic of majority decision. Dut to this logic, the Y/C separation by this IC have no dot appearance or color protruding.

Features of TA8748AN are: (1)3 line comb filter operaiton; (2)center value detecting circuit; (3)vertical edge sharpness correction(vertical secondary differential); (4)vertical edge sharpness correction level control; (5)edge sharpness correction signal coring and peak clip.

The absolute maximum rating of TA8748AN can be summerized as:(1): power supply voltage, Vcc is 12 V; (2): power dissipation, PD max is 1560 mW; (3): input terminal signal voltage, ein is 5 Vp-p; (4): operating temperature range, Topr is -20 to 65; (5): storage temperature range, tstg is -55 to 150.The electro-optical characteristics of TA8748AN can be summerized as:(1): V1H output, V1 is 4.2 V min, 4.5 V typ and 4.8 V max; (2): VD output, V2 is 4.2 V min, 4.5 V typ and 4.8 V max(cf.open); (3): VD input, V3 is 2.7 V min, 3.0 V typ and 33. V max; (4): V1H Del, V5 is 2.7 V min, 3.0 V typ and 33. V max; (5): fsc C , V10 is 4.2 V min, 4.5 V typ and 4.8 V max; (6): fsc B, V11 is 4.2 V min, 4.5 V typ and 4.8 V max.
