3.3V Spread-Spectrum EconOscillator

General Description

Features

The DS1087L is a clock generator that produces a

spread-spectrum (dithered) square-wave output of fre-

quencies from 130kHz to 66.6MHz. The DS1087L is

shipped from the factory programmed at a specific fre-

quency and spread-spectrum percentage. The user still

has access to an internal frequency divider, selectable

2% or 4% dithered output, and programmable output

power-down/disable mode through a 2-wire program-

ming interface. All the device settings are stored in non-

volatile (NV) EEPROM allowing it to operate in

stand-alone applications. The DS1087L has power-

down and output-enable control pins for power-sensi-

tive applications.
