1 / 9 page LM1290 Autosync Horizontal Deflection Processor General Description 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. Features n Full autosync — 22 kHz to 110 kHz with no component switching or external adjustments n No manufacturing trims needed — internal VCO capacitor trimmed on chip n Sample-and-hold circuit for fast top-of-screen phase recovery, even when using composite sync n DC-controlled H phase and duty cycle n Resistor-programmable minimum VCO frequency n Excellent jitter performance n X-ray input disables H drive until VCC powered down n Low VCC disables H drive (VCC < 8.5V) n H output transistor protected against accidental turn on during flyback n Capacitor-programmable frequency ramping, dfVCO / dt, protects H output transistor during scanning mode changes Connection Diagram DS012917-1 FIGURE 1.
