LA75693M
Overview
The LA75693M is a PAL/NTSC multichannel audio VIF/SIF signal-processing IC that makes the minimum number of
adjustments possible. The system is designed so that VCO adjustment makes AFT adjustment unnecessary, thus
simplifying the adjustment steps in endproduct manufacturing. PLL detection is adopted in the FM detector, allowing the
LA75693VA to support multichannel detection for the audio signal. In addition, it also incorporates a buzz canceller that
suppresses Nyquist buzz for improved audio quality.
