DS1089L - Center Spread`Spectrum EconOscillator

General Description

The DS1089L is a clock generator that produces a spread spectrum (dithered) square-wave output of frequencies from 130kHz to 66.6MHz.

The DS1089L is shipped from the factory programmed at a specific frequency.

Key Features

  • Factory-Programmed Square-Wave Generator from 33.3MHz to 66.6MHz.
  • Center Frequency Remains Constant Independent of Dither Percentage.
  • No External Timing Components Required.
  • EMI Reduction.
  • Variable Dither Frequency.
  • User Programmable Down to 130kHz with Divider (Dependent on Master Oscillator Frequency).
  • ±1%, ±2%, ±4%, or ±8% Selectable Dithered Output.
  • Glitchless Output-Enable Control.
  • I2C-Compatible Serial Interf.

Rev 1; 9/05 3.3V Center Spread-Spectrum EconOscillator™ General Description The DS1089L is a clock generator that produces a spread spectrum (dithered) square-wave output of frequencies from 130kHz to 66.6MHz. The DS1089L is shipped from the factory programmed at a specific frequency. The DS1089L is pin-for-pin compatible with the DS1087L, however, the DS1089L dithers at equal percentages above and below the center frequency. The user still has access to the internal frequency divider, selectable ±1%, ±2%, ±4%, or ±8% dithered output, dithering rate, and programmable output powerdown/disable mode through an I2C™-compatible programming interface. All the device settings are stored in nonvolatile (NV) EEPROM allowing it to operate in stand-alone applications.
