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 SiTime vs Quartz Electro Magnetic Susceptibility (EMS) Mean Time Between Failure (Million Hours) - 30 - 39 500 IDT (Fox) 38 SiTime 20X Better 28 Epson TXC 16 Pericom 14 Average Spurs (dB) SiTime - 40 - 40 - 42 - 43 - 45 - 50 - 60 SiTime 54X Better - 70 - 73 - 80 - 90 200 0 Kyocera 600 400 Figure 1.
