The LA7567B and LA7567BM are PAL/NTSC multiformat audio VIF/SIF IF ICs that adopt a semiadjustment-free system. The VIF block adopts a technique that makes AFT adjustment unnecessary by adjusting the VCO, thus simplifying the adjustment steps in the manufacturing process. PLL detection is adopted in the FM detector to support multi-format audio detection. A built-in SIF converter is included to simplify multi-format system designs. A 5-V power-supply voltage is used to match that used in most multimedia systems. In addition, these ICs also include a buzz canceller to suppress Nyquist buzz and provide high audio quality. The LA7567B and LA7567BM feature improvements over the LA7567N and LA7567NM in the audio and video signal-to-noise ratios and the video signal amplitude. |
