1 / 13 page Overview 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 end- product 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. Functions [VIF Block] • PLL detector with minimum number of adjustments • AFT • Equalizer amplifier • RF AGC [First SIF BLOCK] • First SIF detector • HPF [SIF Block] • PLL-based FM detector [Muting Block] • AV muting Features • Excellent buzz and buzz/beating characteristics provided by a PLL detection technique that includes a buzz canceller. • The second IF AGC filter is built in. • No coils are used in the AFT and SIF circuits, making them adjustment free.
