LA7674

Ordering number : ENN4361 Monolithic Linear IC LA7674 Color TV Single-Chip Signal Processor for NTSC Systems (PLL Detection) Overview The LA7674 improves upon the black-level, horizontaljitter, 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.
