Ordering number : EN6099
Monolithic Linear IC
LA7567B, 7567BM
TV and VCR VIF/SIF IF Signal-Processing Circuit with PAL/NTSC Multi-Format Audio Support
Overview
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.
