SiT8002AA
Description
The SiT8002AA oscillator family is composed of the world’s
smallest, high-performance programmable oscillators. The
SiT8002AA is suitable for use in clock generation for
automotive, industrial, and space/Satellite applications.
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.
The SiT8002AA, by eliminating the quartz crystals, has
improved immunity to the environmental effects of vibration,
shock, strain, and humidity.
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.

Notes:
1. The 2.5V device can operate from 2.25V to 3.63V with higher output drive, however, the data sheet parameters cannot be guaranteed. 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.
“tensymetry”这个词在《韦伯斯特词典》中没有解释，但在医学界却广为人知。由Tensys Medical Systems公司开发的tensymetry是一种使用生物机械、电气、软件工程的专有组合技术。利用这三种强大的技术，你可在手术室内对病人的心跳血压进行精确、连续、实时和非侵入性测量。 该技术结出的果实就是该公司的T-line Tensymeter产品。该产品线的最新进展是去年...[详细]
