Autosync Horizontal Deflection Processor

The LM1290 is a high-performance, low-cost deflection solu- tion for autosync monitors. The LM1290 provides full autosync capability, DC controls and complete freedom from manufacturing trims. Its continu- ous capture range is from 22 kHz to 110 kHz (1:5). Mode change frequency ramping, for protection of the horizontal deflection output Transistor is programmable by using an ex- ternal capacitor. Together with the National Semiconductor LM1296 Raster Geometry Correction System for Multi-Frequency Displays excellent performance is offered. The two-chip solution pro- vides the advantage of good jitter performance, simplified board layout, and lower system cost. The LM1290 is packaged in a 14-pin plastic DIP package.
