Overview
DS1086 19-6224; Rev 2; 3/12 Spread-Spectrum EconOscillator General Description 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 radiated-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.
