Monolithic Linear IC
LA7565E, 7565KM
IF Signal-Processing IC for PAL/NTSC Multi-System Audio TV and VCR Products
Overview
The LA7565E and LA7565KM are PAL/NTSC multisystem 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...
