VIF/SIF IF Signal-Processing Circuit for TV and VCR Products
Overview
The LA75676V-S is an NTSC intercarrier VIF/SIF IC that adopts a semi-adjustment-free structure. In particular, it uses VCO adjustment to make AFT adjustment unnecessary and thus simplifies the overall adjustment process. A PLL-based technique is adopted for FM detection. The 5 V supply
voltage provides compatibility with other multimedia systems. In addition it achieves high audio quality by incorporating a built-in buzz canceller that suppresses Nyquist buzz.
Features
No AFT or SIF coils are used, thus eliminating adjustments. Excellent audio performance due to the built-in buzz canceller. VCC = 5 V and a low power dissipation of 250 mW.
