Monolithic Linear IC

LA7565B, 7565BM

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 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 Nyquist buzz to achieve

improved audio quality.
