Overview
The LA7566 is a VIF/SIF IC that supports PAL and
NTSC multisound and that adopts a semi-adjustment-free
system. To simplify adjustment, the VIF block adopts a
technique in which AFT adjustment is no longer required
by VCO adjustment. The SIF block supports audio multi-
detection by adopting a PLL detection technique. The SIF
block provides 4 inputs with IC internal switching for easy
design of multi-sound systems. Additionally, these
switches can also be used for video system sound trap
switching. The LA7566 also includes a buzz canceller that
suppresses Nyquist buzz to achieve improved audio
quality.
