CrystalFree™ (Solid-State and pMEMS) Oscillators and Crystal Replacements

Crystal Free CMOS/Silicon oscillators, MEMS Oscillators and Crystal Replacements

IDT's CrystalFree™ products replace quartz-crystal oscillators and passive crystal (XTAL) resonators with advanced technologies. Taking advantage of the economies and scale of both semiconductor processes and standard plastic packages, CrystalFree products offer a number of advantages over traditional quartz-crystal based products. Customers worldwide are resolving the challenges encountered with quartz-crystal technology by taking advantage of IDT CrystalFree technology.

IDT’s Crystal Free Solid-State oscillators are based on over 35 patents (granted or filed) and consume as little as 1/10th the power of XO products. Also known as CMOS oscillators or silicon oscillators, these devices provide significant price saving, lead time, and performance improvements as compared to quartz-crystal oscillators. They have a much broader frequency range and are offered at a significant price savings compared to standard quartz-crystal oscillators. To date, IDT has shipped millions of devices with this patented technology, with more shipping every day.

IDT CrystalFree Piezo MEMS (pMEMS™) Oscillator technology is transforming the frequency control market. Combining the advantages of piezoelectric quartz with the advantages and reliability of silicon MEMS resonators, IDT’s pMEMS resonator technology combines the strong electromechanical coupling of the piezoelectric material with the stability and low damping of single crystal silicon to create a passive frequency source of unparalleled performance and reliability. Based on over 40 patents (granted or filed), IDT’s CrystalFree pMEMS resonators are the world’s smallest hermetically-sealed wafer level package (WLP) resonators.
