IF Signal Processing
(VIF/SIF for Hi-Fi)
Overview
The LA75694M is a PAL/NTSC split Support VIF/SIF for Hi-Fi 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 LA75694M to support multichannel detection for the audio signal. In addition, it also incorporates a buzz canceller
that suppresses Nyquist buzz for improved audio quality.
