Overview
The LA7567N and LA7567NM 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.

FEATUREs
• Both AFT and SIF inductors built in, thus making adjustment of external inductance unnecessary.
• A PAL/NTSC multi-format audio system can be constructed easily.
• Built-in buzz canceller for excellent audio performance.
• VCC= 5 V, low power dissipation (250 mW)
