The The SiT8002AA, by eliminating the quartz crystals, has SiT8002AA is suitable for use in clock generation for improved immunity to the environmental effects of vibration, automotive, industrial, and space/Satellite applications. shock, strain, and humidity. 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 MEMS oscillators are inherently more reliable, have more consistent performance and are always in stock. 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.
