I have an issue I'm trying to understand and resolve. I've been working on a mulit-band beacon where for 50 MHz I use CLK1 @ 50 MHz, and 144 MHz I use CLK1 @ 144 MHz.
For 222 and 432 I use CLK0 as an LO to a mixer, and CLK2 as the IF to the mixer and the output = 222 or 432 MHz.
This works.
However, after I use the Si5351a for 222 and 432 MHz and the loop goes to do 50 MHz on CLK1 again it no longer outputs.
I keep thinking this may be an issue where something isn't being reset like the PLL's.
I've tried to set PLL's for each band, but I'm not 100% sure I'm doing it right.
I can set PLL for a single band ok and it seems to work.
I'm stumped. I can provide my sketch if that would be useful. I suspect it's something simple I've missed. But after a week of trying and researching I just can't seem to resolve the issue.

Can you help set me straight?
