The SiT8002 is suitable for use in clock generation for consumer, portable, industrial, automotive, and computation applications. This oscillator family is packaged in standard low-cost plastic QFN-type IC packages with footprints that match common quartz surface mount products. MEMS oscillators are inherently more reliable, have more consistent performance and are always in stock. The SiT8002, by eliminating the quartz crystals, has improved immunity to the environmental effects of vibration, shock, strain, and humidity. To order samples, go to www.sitime.com and click on Request Sample" link. MEMS resonators are 1000x smaller by volume than quartz resonators and are built in high volume CMOS fabs instead of small custom manufacturing facilities. Due to their small size, massive lot sizes, and simpler manufacturing processes Absolute Maximum Ratings Attempted operation outside the absolute maximum ratings of the part may cause permanent damage to the part. Actual performance of the IC is only guaranteed within the operational specifications not absolute maximum ratings. Absolute Maximum Table Parameter Min. Max.
