3.3V Center Spread-Spectrum EconOscillator™

General Description

The DS1089L is a clock generator that produces a

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

quencies from 130kHz to 66.6MHz. The DS1089L is

shipped from the factory programmed at a specific fre-

quency. The DS1089L is pin-for-pin compatible with the

DS1087L, however, the DS1089L dithers at equal per-

centages above and below the center frequency. The

user still has access to the internal frequency divider,

selectable

±1%, ±2%, ±4%,

±8%

dithered output,

dithering rate, and programmable output power-

down/disable mode through an I

C-compatible pro-

gramming interface. All the device settings are stored

in nonvolatile (NV) EEPROM allowing it to operate in

stand-alone applications. The DS1089L also has

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

sensitive applications.
