LA7851 Description
Ordering number:ENN1775A Monolithic Linear IC LA7851 CRT Display Synchronization Deflection Circuit 0.25 Overview The LA7851 is a sync deflection circuit IC dedicated to CRT display use. It can be connected to the LA7832, 7833 (for vertical output use) to form a sync deflection circuit that meets every requirement for CRT display use. So far, ICs for color TV use have been applied to the sync deflection circuit for...
LA7851 Key Features
- The vertical pull-in range 20Hz permits non-adjusting at vertical sync 50Hz/60Hz
- The horizontal oscillation frequency can be adjusted stably from 15kHz to 100kHz
- The horizontal display can be shifted right/left
- The horizontal/vertical sync input can be used intact re
- The AFC feedback sawtooth wave can be obtained by
- Any duty of the horizontal pulse can be set
- Good linearity because DC bias at vertical output stage is subject to sampling control within retrace time
- Vertical OSC
- Horizontal OSC
- Vertical sawtooth wave generator
