SiTime's SIT8918/9 and SIT8920/1 series of high-temperature oscillators provide ±20 PPM frequency stability from -55°C to +125°C. They are 2x better in stability, 20x more reliable, and 30x more resistant to shock and vibration compared to quartz. SiTime oscillators enable higher system performance and reduce field failures in harsh environments. SiTime’s MEMS oscillators exhibit performance far greater than comparable crystals oscillators. SiTime has in-house MEMS and analog CMOS expertise, which allow SiTime to develop the most reliable products. Oscillators are available in plastic packages which are up to 54 times more immune to external electromagnetic fields than quartz oscillators. These MEMS oscillators are vacuum sealed using an advanced EpiSeal process that eliminates foreign particles, which provides long term aging and reliability. For the same device in a SOT23-5 package, refer to the SiT2018B.
