SiT8102
Description
The SiT8102 is the next generation of the SiT8002 program-
mable oscillator with lower phase noise, lower jitter, and a
higher frequency range. SiTime oscillators are the smallest,
high-performance programmable oscillator available and are
suitable for use in high speed serial communications,
consumer, portable, industrial, automotive and computation.
This oscillator is packaged in standard low-cost plastic and
chip-scale IC packages.
System reliability is also increased with the SiT8102 by elimi-
nating the quartz crystal and 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 at 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 specifications cannot be guaranteed. Please contact factory
for this option.
2. The output driver strength 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]
