sit8002 page 2 of 7 description the sit8002 oscillator family is composed of the world?s smallest, high-performance programmable oscillators. the sit8002 is suitable for use in clock generation for consumer, portable, industrial, automotive, and comput ation applications. this oscillator family is packa ged in standard low-cost plastic qfn-type ic packages with fo otprints that match common quartz surface mount products. mems resonators are 1000x smaller by volume than quartz resonators and are built in hi gh volume cmos fabs instead of small custom manufacturing facilities. due to their small size, massive lot sizes, and simp ler manufacturing processes mems oscillators are inherently more reliable, have more consistent performance and are always in stock. the sit8002, by eliminating t he 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. 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 guarante ed within the operationa l specifications not absolute maximum ratings. notes: 1. the 2.5v device can operate from 2.25v to 3.63v with higher output drive, however, the data s heet parameters cannot be guaran teed. please contact factory for this option. 2. the output driver strenght can be programmed to drive up to 30pf load. please contact factory for this option. ab solute maximum table parameter min. max. unit storage temperature -65 150 c vdd -0.5 +3.65 v electrostatic discharge 6000 v theta ja ( with copper plane on vdd and gnd) ? 75 c/w theta jc (with pcb traces of 0.010 inch to all pins) ? 24 c/w soldering temperature (follow standard pb free soldering guidelines) 260 c number of program writes 1na program retention over -40 to 125c, process, vdd (0 to 3.6v) 1,000+ years operating conditions parameter min. typ. max. unit supply voltages, vdd [1] 2.97 3.3 3.63 v 2.25 2.5 2.75 v 1.7 1.8 1.9 v extended commercial operatingtemperature -20 - 70 c industrial operating temperature -40 - 85 c maximum load capacitance [2] - - 15 pf vdd ramp time 0 - 200 ms environmental compliance parameter condition/test method mechanical shock mil-std-883f, method 2002 mechanical vibration mil-std-883f, method 2007 temperature cycle jesd22, method a104 solderability mil-std-883f, method 2003 moisture sensibility level msl1
