General Description
LA75691 General Description
The LA75691 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 LA75691 to support multichannel detection for the audio signal. In addition, it also incorporates a buzz canceller that suppresses Nyquist buzz for improved audio quality.
