SIT1252 embedded mems resonator 1 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 di e 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 rel iability 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 sup port 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 t he - 40c to 85c temperature range. other features include a low sustaining amplifier power and extremely small die size. benefits ? e nables smallest embedded solution , reduces board space ? ? ? ? features ? 524 khz resonator for 32.768 khz rtc ? 100 over temp frequency stability ? 5 ppm stability on rtc ? 50,000 quality factor ? ultra - small size: 420 m x 420 m ? 50,000 g shoc k and 70 g vibration resistance, 10x better than quartz ? <1 a system current applications ? ? ? ? metering soc ? embedded rtc ref clock ? portable medical ? 2017 sitime corp. the information contained herein is subject to change without notice. www.sitime.com rev. 1.0 08/29 /2017 sitime's mems resonators can be embedded into socs/asics, eliminating the external rtc, saving board space, simplifying design, reduc ing bom , and improving reliability semiconductor devices that benefit from mems resonator integration: ? microprocessors ? microcontrollers ? application processors for mobile ? real time clock ics ? low power radios ? sensor node ics ? watch ics
