... LA75693M Overview The LA75693M is a PAL/NTSC multichannel audio VIF/SIF signal-processing IC that makes the minimum number of adjustments possible. The system is designed so that VCO adjustment makes AFT adjustment unnecessary, thus simplifying the adjustment steps in endproduct manufacturing. PLL detection is adopted in the FM detector, allowing the LA75693VA to support multichannel detection for the audio signal ...
