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.

An evaluation kit is available:  DS1070K
