SiTime’s SiT1630 series of MEMs resonators ultra-small and ultra-low power 32.768 kHz oscillators which are optimized for mobile and other battery-powered applications. This family is a low-power alternative to existing 32 kHz oscillators and its 1.5 V to 3.63 V operating supply voltage range make it an ideal solution for mobile, handheld, and IoT applications. These devices consist of MEMS resonators and a programmable analog circuit. These MEMS resonators are built with SiTime’s unique MEMS First™ process. A key manufacturing step is EpiSeal™ during which the MEMS resonator is annealed with temperatures over 1000°C. EpiSeal creates an extremely strong, clean vacuum chamber that encapsulates the MEMS resonator and ensures the best performance and reliability. Compared to legacy quartz products, SiTime’s SiT1630 family in the CSP is up to 80% smaller with a 1.2 mm² total footprint.
