Spread-Spectrum EconOscillator  
DS1086  
General Description  
Features  
The DS1086 EconOscillator™ is a programmable clock  
generator that produces a spread-spectrum (dithered)  
square-wave output of frequencies from 260kHz to  
133MHz. The selectable dithered output reduces radi-  
ated-emission peaks by dithering the frequency 2% or  
4% below the programmed frequency. The DS1086 has  
a power-down mode and an output-enable control for  
power-sensitive applications. All the device settings are  
stored in nonvolatile (NV) EEPROM memory allowing it  
to operate in stand-alone applications.  
o User-Programmable Square-Wave Generator  
o Frequencies Programmable from 260kHz to  
133MHz  
o 2% or 4% Selectable Dithered Output  
o Glitchless Output-Enable Control  
o 2-Wire Serial Interface
