SI501 32kHz to 100MHz Programmable oscillator

Silicon labs SI501 one-time-programmable CMEMS Oscillator

We use crystals oscillator to generate local oscillator, however crystal oscillator comes with fixed frequency and we can only pick the standard frequencies listed by manufacturer, sometimes we needs a particular frequency which is not available in the market. Recently there are some programmable oscillator IC on the market, and these IC using on-chip MEMS resonator as source and PLL circuitry to convert the base frequency to the target frequency, in the range of 32kHz to 100MHz. 

The programmer, comes with a windows GUI, through USB.

I hope I can use these oscillator to replace some of the crystal oscillator in the projects
