Sanyo LA7567GM Specifications

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.
The LA7567GM is an NTSC SPLIT support VIF/SIF IF IC that adopts 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. A 5-V power­supply voltage is used to match that used in most multimedia systems. In addition, this IC also includes 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.
• Built-in buzz canceller for excellent audio performance.
•VCC= 5 V, low power dissipation (250 mW)
