LA7567BM - TV and VCR VIF/SIF IF Signal-Processing Circuit
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-form
