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.
