Product Summary

The LA75675M-S-TLM 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.
