Silicon Labs Si50x CMEMS® Oscillators

Silicon Labs Si50x CMEMS Oscillators

Silicon Labs' Si50x CMEMS® general-purpose oscillators are a perfect fit for low cost, high shock applications. Their single-chip construction provides lower cost, greater reliability, and better aging than traditional crystal oscillators of the same class. They are highly robust against shock and vibration, offer ±20ppm frequency stability guaranteed for 10 years, and are drop-in compatible to traditional XOs in the same class. They are configurable to support any frequency between 32kHz and 100MHz right on customers' desktops with the Si50X-FPB1-CUST field programming kit, or from the factory in less than two weeks.

Si50x CMEMS Oscillators

CMEMS general-purpose oscillators provide lower cost, greater reliability, and better aging than traditional crystal oscillators of the same class. Their single-chip architecture resolves fundamental manufacturing challenges through a patented technology and process that integrate the MEMS resonator directly on top of the CMOS die, creating a fully-integrated, monolithic IC solution. This low-cost, high-volume foundry technology, coupled with standard assembly and exacting quality standards make the Si50x oscillators cost effective, easy to configure with 10-years of guaranteed performance across temperature, and drop-in compatible to traditional XO footprints.
