MEMS Oscillator

ILSI MEMS oscillators incorporate MEMS resonators which are microelectromechanical structures that define stable frequencies. MEMS oscillators offer a high level of resilience against vibration and mechanical shock, and reliability with respect to temperature variation.  MEMS are excellent for ruggedized commercial or mil/aero applications due to the cost-effective standard plastic packages.  All ILSI MEMS products offer QFN packages that are footprint compatible to quartz clock oscillator devices.

ILSI MEMS highlights include: Better stability and aging with no activity dips.  Programmable Silicon. Excellent phase noise performance featuring typical RMS phase jitter of 500 femto-seconds, and a maximum of 1ps, integrated from 12 kHz to 20MHz. Samples in 5 days or less.

Our oscillators are both RoHS Compliant and Pb Free. A compliance letter may be downloaded here.

Our oscillators are in compliance with current REACH SVHC standards. A compliance letter may be downloaded here.
