Overview
The LA7674 improves upon the black-level, horizontal-
jitter, switch-on drift performance of the single-chip
LA7672 used to date. Also a single-chip IC, the LA7674
is for color TVs based on the NTSC (National Television
System Committee) system with an on-chip circuit for all
VIF, SIF, video, chroma and deflection signal processing.
Functions and Features
[VIF]
PLL detection (high video and audio quality)
