1 / 14 page Overview The LA7567N and LA7567NM are PAL/NTSC multi- format audio VIF/SIF IF ICs that adopt a semi- adjustment-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. Functions [VIF] • VIF amplifier • PLL detector • BNC • RF AGC • EQ amplifier • AFT • IF AGC • Buzz canceller [First SIF] • First SIF • First SIF detector • AGC [SIF] • Multi-format SIF converter • Limiter amplifier • PLL FM detector 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) Package Dimensions unit: mm 3067-DIP24S unit: mm 3112-MFP24S Monolithic Linear IC 50698RM (OT) No. 5765-1/14 SANYO: DIP24S [LA7567N] SANYO: MFP24S [LA7567NM] SANYO Electric Co.,Ltd.
