The LA7567BVA is a PAL/NTSC multiformat VIF/SIF IC that adopts a semi-adjustment-free system. The VIF block
adopts a system in which VCO adjustment makes AFT adjustment unnecessary to simplify adjustment. The FM
detector adopts a PLL detection system that supports multi-detection audio. This IC also integrates an SIF converter,
making design of multisystem products easier. The LA7567BVA uses the 5V supply voltage common in multimedia
equipment. In addition, the LA7567BVA also includes a buzz canceller that suppresses Nyquist buzzing for superb
audio quality.
Functions
VIF block: VIF amplifier, buzz canceller, PLL detector, IF AGC, RF AGC, AFT, equalizer amplifier.
First SIF block: First SIF amplifier, first SIF detector.
SIF block: Limiter amplifier, PLL FM detector.
Features
No AFT or SIF coils are required, making these circuits adjustment free.
Allows PAL/NTSC multiformat systems to be implemented easily.
Built-in buzz canceller for excellent audio quality.
VCC = 5V, low power: 250mW
