Overview
The LA7567EV is 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 5V 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. The LA7567EV feature improvements over the LA7567N and
LA7567NM in the audio and video signal-to-noise ratios and the video signal.
Functions
VIF block: VIF amplifier, PLL detector, BNC, RF AGC, EQ amplifier, AFT, IF AGC, buzz canceller.
First SIF block: first SIF, first SIF detector, AGC.
SIF block: multi-format SIF converter, limiter amplifier, PLL FM detector.
Features
No AFT or SIF coils are required, making these circuits adjustment free.
A PAL/NTSC multi-format audio system can be constructed easily.
Built-in buzz canceller for excellent audio performance.
VCC = 5V, low power dissipation (250mW)
