Hi
It would be *very* interesting to see what happens if you sync it up to a 10 MHz input ….

I used the SiLabs "ClockBuilder" software to configure four outputs -- 10 MHz, 15 MHz, 29.999 999 9 MHz, and 144.2 MHz -- all using the 45 MHz crystal that comes with the EVM. Attached is a phase noise plot of the 10 MHz and 29.999 999 9 MHz signals. I would say this isn't too bad! This performance is certainly sufficient for any of the RF work I have in mind.
