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)
