VIF/SIF Signal Processing IC
Overview
The LA75710VA is an NTSC support VIF/SIF signal processing IC that adopts a semi-adjustment-free system.
The video-S/N and audio-S/N characteristics are improved. Further, it includes a circuit to prevent video over modulation.
For the AFT function it adopts digital AFT. PLL detection is adopted in the FM detector. A 5V 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.
