Hi All,
I am having lots of issues with the USRP 64MHz (20ppm) on board
oscillator which does not allow me to get exact and constant RF
frequencies out of the RFX900 board. I can not really fix that in SW so
I was thinking about replacing the 64MHz crystal with a more precise
one. Has anybody a suggestion of which part to use?
I have replaced the crystal with the 20ppm crystal, but I was unable to
get an "exact and constant" frequency. I ultimately added a software
PLL to track the clock errors. Before I upgraded my software PLL, I
used a signal generator as an external clock source which worked very well.
