Spread-Spectrum EconOscillator

DS1086

General Description

Features

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.
