LA7853 Description
Ordering number:ENN2873 Monolithic Linear IC LA7853 CRT Display Synchronization Deflection Circuit Overview The LA7853 is a sync deflection circuit IC dedicated to CRT display use. It can be connected to the LA7832, 7833, 7837, 7838 (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...
LA7853 Key Features
- The vertical pull-in range is approximately 20Hz, 2 times that of the LA7852, at fV=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 vertical linearity because DC bias at vertical output stage is subject to sampling control within retrace time
- Excellent interlace and vertical jitter characteristics on the high-definition display because of independent GND pins f
