Overview
The LA7567N and LA7567NM are PAL/NTSC multi-
format audio VIF/SIF IF ICs that adopt a semi-
adjustment-free system. The VIF block adopts a technique
that makes AFT adjustment unnecessary by adjusting the
VCO, thus simplifying the adjustment steps in the
manufacturing process. PLL detection is adopted in the
FM detector to support multi-format audio detection. A
built-in SIF converter is included to simplify multi-format
system designs. A 5-V power-supply voltage is used to
match that used in most multimedia systems. In addition,
these ICs also include a buzz canceller to suppress Nyquist
buzz and provide high audio quality.
