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 radi-
ated-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.
