LA7674 datasheet

 

Description :

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.

Functions and Features

[VIF]
1. PLL detection (high video and audio quality)
2. High-gain VIF amplifier
3. High speed AGC
4. On-chip APC time constant switch

[SIF]
1. Simultaneous sound IN/OUT
2. Video/audio simultaneous muting, or audio-only muting possible

[Deflection]
1. Adjustment-free horizontal, vertical synchronization
2. Dual AFC system with excellent anti-noise characteristics
3. External adjustment of vertical synchronization sensitivity
4. Vertical size is constant with no-signal
