Anybody use these MEMS Oscillators from Microchip? How is it comparing to Si570 or Si5351?

Si570 – 0.25 to 0.6 ps jitter

Si5351 – 75 ps jitter

Microchip: 7.5 ps jitter


I would place the Microchip parts as 10x better than the si5351, 10x worse than the si570.  That is not a bad place to be.

I fully agree!  The only advantage I can see for the Si5351 is lower current draw, which may be the reason to use it in portable, battery-powered rigs such as the KX2.  Cost difference may be a factor for high-volume products but insignificant for individual builders. Why use an inferior part when the better part is available?

They look usable specially for portable use with low power consumption
but they are fixed frequency devices, the frequency is set at the
factory and not changeable unlike the SI parts. So their use is more

Not totally true.

I use the ABRACON ASFLM parts and have a programmer.  they are program once however but the 
cost for each is low.  Unfortunately the jitter is too high for communications use but fine 
digital use.  They program for any frequency from 1 to 150mhz.

There are other parts that are also user one time programmable.

Handy for computer applications like baud rate timing and such.
