SiT8002
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 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 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 SiT8002, 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.
