Spread Spectrum

SiTime’s EMI reduction oscillators ensure emissions compliance through spread spectrum clocking and rise/fall time adjustment of the clock signal. They are supported on SiTime’s Time Machine II programmer, which allows engineers to quickly reduce emissions levels and ensure that customers pass compliance.
• Up to 17 dB on fundamental frequency and 30 dB on harmonics
• Wide spread range: Up to 4% pk-to-pk
• FlexEdge™ configurable rise/fall time options: 0.25 ns to 40 ns slew rates
