SiT1252

Embedded MEMS Resonator

SiTime's MEMS resonators can be embedded into

SOCs/ASICs, eliminating the external RTC, saving

board space, simplifying design, reducing BOM,

and improving reliability

SiTime is the only company to provide silicon-timing solutions that can be integrated into an ASIC/SoC at the die level. SiTime

MEMS resonators are available in die form, which can be cost-effectively embedded with other die inside a plastic

semiconductor package. The resonator is vacuum sealed with SiTime's EpiSeal™ process at the wafer level to provide an ultra-

clean, hermetic environment which enables high quality, stability, and reliability over the lifetime of the resonator. Integrating a

MEMS resonator eliminates the need for an external RTC clock reference and offers customers integrated timing functionality

that reduces support costs and increases time to market.

The SiT1252 is SiTime’s 2nd generation 524 kHz resonator. Improvements include resistance to mechanical stressors such as

overmold and underfill. The SiT1252 utilizes SiTime’s TempFlat™ technology that results in a MEMS resonator with ±100 ppm

frequency stability over the -40°C to 85°C temperature range. Other features include a low sustaining amplifier power and

extremely small die size.
