1 to 141 MHz, Spread-spectrum Oscillator


The SiT9005 spread spectrum oscillator (SSXO) is field programmable and designed to accelerate time to revenue by ensuring emissions compliance, a pivotal milestone for any electronics product.

 Up to 30 dB reduction

 Plug-and-play solution without design changes

 Field programmable for instant validation

Emissions compliance failure, which typically happens during the last stage of product development, can result in unplanned troubleshooting efforts and costly production delays. The SiT9005 solves EMI problem by offering two techniques for compliance: spread spectrum clocking and rise/fall time adjustment of the clock signal. What’s more, the SiT9005 is supported by SiTime’s Time Machine II programmer that allows engineers to instantly program spread modulation and/or drive strength to quickly reduce emissions levels.
