Ordering number : ENN7939B SANYO Semiconductors DATA SHEET Monolithic Linear IC LA7567BVA TV and VCR IF Signal Processor (VIF + SIF + SIF converter) 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.
