IF Signal-Processing IC for PAL/NTSC Multi-System Audio TV and VCR Products
Overview
The LA7565B/M is a PAL/NTSC multi-system audio VIF/SIF signal-processing IC that adopts a minimaladjustment technique.
The VIF circuit adopts a minimaladjustment 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...
