LA7567GM
TV and VCR VIF/SIF IF Signal-Processing Circuit with
NTSC SPLIT Support
Overview
The LA7567GM is an NTSC SPLIT support VIF/SIF IF
IC that adopts 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. A 5-V power-
supply voltage is used to match that used in most
multimedia systems. In addition, this IC also includes a
buzz canceller to suppress Nyquist buzz and provide high
audio quality.
