Monolithic Linear IC
LA7567GM
TV and VCR VIF/SIF IF Signal-Processing Circuit with
NTSC SPLIT Support
Overview
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)
