Description
The DS1086LPMB1 peripheral module provides the necessary hardware to interface the DS1086L 3.3V spread-spectrum EconOscillator™ to any system that utilizes Pmod™-compatible expansion ports configurable for I²C communication. The DS1086L is a 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 frequency 0.5%, 1%, 2%, 4%, or 8% below the programmed frequency. The DS1086L has a power-down mode and an output-enable control for power-sensitive applications.
Refer to the DS1086L IC data sheet for detailed information regarding operation of the IC.
