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]

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
