Overview
DS1086L 3.
3V Spread-Spectrum EconOscillator General Description The DS1086L EconOscillator™ is a 3.
3V programmable clock generator that produces a spread-spectrum (dithered) square-wave output of frequencies from 130kHz to 66.
6MHz.
The selectable dithered output reduces radiated-emission peaks by dithering the frequency 0.
5%,1%, 2%, 4%, or 8% below the programmed frequency.
The DS1086L 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.
