LM1290  
Autosync Horizontal Deflection Processor  
General Description  
The LM1290 is a high-performance, low-cost deflection solu-  
tion for autosync monitors.  
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  
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.  
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  
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.  
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  
The LM1290 is packaged in a 14-pin plastic DIP package.  
n Capacitor-programmable frequency ramping, dfVCO / dt,  
protects H output transistor during scanning mode
