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)
