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 I...
