1 / 21 page Ordering number : ENN7779A SANYO Semiconductors DATA SHEET SANYO Electric Co.,Ltd. Semiconductor Company TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN 81505MS OT B8-7701 No.7779-1/21 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) LA7567EV Monolithic Linear IC TV and VCR VIF/SIF IF Signal-Processing Circuit with PAL/NTSC Multi-Format Audio Support Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft's control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage. Consult with your SANYO representative nearest you before using any SANYO products described or contained herein in such applications. SANYO assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all SANYO products described or contained herein.
