The LM1290 is a high-performance, low-cost deflection solution for autosync monitors.

The LM1290 provides full autosync capability, DC controls and complete freedom from manufacturing trims. Its continuous 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 external capacitor.

Together with the National Semiconductor LM1296 Raster Geometry Correction System for Multi-Frequency Displays, excellent performance is offered. The two-chip solution provides the advantage of good jitter performance, simplified board layout, and lower system cost. The LM1290 is packaged in a 14-pin plastic DIP package.
