DS1086L
3.3V Spread-Spectrum EconOscillator
General Description
The DS1086L EconOscillator™ is a 3.3V programmable
clock generator that produces a spread-spectrum
(dithered) square-wave output of frequencies from
130kHz to 66.6MHz. The selectable dithered output
reduces radiated-emission peaks by dithering the fre-
quency 0.5%,1%, 2%, 4%, or 8% below the pro-
grammed frequency. The DS1086L has a power-down
mode and an output-enable control for power-sensitive
applications. All the device settings are stored in non-
volatile (NV) EEPROM memory allowing it to operate in
stand-alone applications.
