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%, or ±8% dithered output,
dithering rate, and programmable output power-
down/disable mode through an I2C-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.
