Overview
The LA7565E and LA7565KM are PAL/NTSC multi-
system audio VIF/SIF signal-processing ICs that adopt a
minimal-adjustment technique. The VIF circuit adopts a
minimal-adjustment technique in which AFT adjustment is
made unnecessary by VCO adjustment to simply end
product adjustment. The FM detector circuit uses PLL
detections to support multi-system audio detection. Since
the LA7565BM include an SIF converter on chip, it is easy
to implement multi-system audio. In addition, it also
includes a buzz canceller that suppresses Nyquist buzz to
achieve improved audio quality. The LA7565G and
LA7565KM feature improvements over the LA7565B and
LA7565BM in the FM low-range frequency characteristics,
vertical synchronization buzz, and AFT drift.
