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.
