Rev 1.08 Page 10 of 13 www.sitime.com Silicon MEMS Outperforms Quartz Best Reliability Best Electro Magnetic Susceptibility (EMS) Silicon is inherently more reliable than quartz. Unlike quartz suppliers, SiTime has in-house MEMS and analog CMOS expertise, which allows SiTime to develop the most reliable products. Figure 1 shows a comparison with quartz technology. SiTime’s oscillators in plastic packages are up to 54 times more immune to external electromagnetic fields than quartz oscillators as shown in Figure 3. Why is SiTime Best in Class:    SiTime’s MEMS resonators are vacuum sealed using an advanced EpiSeal™ process, which eliminates foreign particles and improves long term aging and reliability World-class MEMS and CMOS design expertise Why is SiTime Best in Class:  Internal differential architecture for best common mode noise rejection Electrostatically driven MEMS resonator is more immune to EMS Reliability (Million Hours) SiTime 1,140 IDT 38 EPSN 28 KYCA EPSN TXC CW SLAB SiTime Figure 3.
