Product Summary
This is a product group of MEMS oscillator-based OCXOs. (common name: Emerald)
It supports frequencies from 1 to 220 MHz, and is very small compared to conventional crystal OCXOs at 9 x 7 mm.
In addition, it is possible to solve many problems faced by crystal OCXO.
Resistant to external environmental stresses such as vibrations, temperature changes, and impacts, and does not require external components such as mechanical protection for heat insulation.
It provides unparalleled ease-of-use, highly reliable timing performance of the highest level and the shortest lead time for communications and networks.
Main OCXO lineup
SiTime MEMS oscillators can be freely selected from the listed specifications.
The SiT5721 can be digitally tuned using I2C. This reduces board noise.
