DS1087L - Spread-Spectrum EconOscillator

General Description

The DS1087L is a clock generator that produces a spread-spectrum (dithered) square-wave output of frequencies from 130kHz to 66.6MHz.

The DS1087L is shipped from the factory programmed at a specific frequency and spread-spectrum percentage.

Rev 1; 11/03 3.3V Spread-Spectrum EconOscillator General Description The DS1087L is a clock generator that produces a spread-spectrum (dithered) square-wave output of frequencies from 130kHz to 66.6MHz. The DS1087L is shipped from the factory programmed at a specific frequency 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 programming interface. All the device settings are stored in nonvolatile (NV) EEPROM allowing it to operate in stand-alone applications. The DS1087L has powerdown and output-enable control pins for power-sensitive applications. Features ♦ Factory Programmed Square-Wave Generator from 130kHz to 66.
