DS1086L 3.3V Spread-Spectrum EconOscillator General Description Features The DS1086L EconOscillator is a 3.3V programmable User-Programmable Square-Wave Generator clock generator that produces a spread-spectrum Frequencies Programmable from 130kHz to (dithered) square-wave output of frequencies from 66.6MHz 130kHz to 66.6MHz. The selectable dithered output reduces radiated-emission peaks by dithering the fre- 0.5%, 1%, 2%, 4%, or 8% Selectable Dithered quency 0.5%,1%, 2%, 4%, or 8% below the pro- Output grammed frequency. The DS1086L has a power-down Adjustable Dither Rate mode and an output-enable control for power-sensitive applications. All the device settings are stored in non- Glitchless Output-Enable Control volatile (NV) EEPROM memory allowing it to operate in 2-Wire Serial Interface stand-alone applications.
