1 / 17 page 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 fre- quency 0.5%,1%, 2%, 4%, or 8% below the pro- grammed frequency. The DS1086L has a power-down mode and an output-enable control for power-sensitive applications. All the device settings are stored in non- volatile (NV) EEPROM memory allowing it to operate in stand-alone applications.
