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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
