Hi Ali,
The daughterboards have their own clock generators, but they are not
exactly 'independent'. At least they don't have to be, as they share the
same reference clock. Look at the block diagram:
https://kb.ettus.com/images/9/9d/USRP_N310_N300_DB_Schematic.pdf
and "Ref Clock" block. I don't have N310 and I know that reality can be
a bit far from expectations (i.e. look at my "What makes sense and what
doesn't in the way carrier frequency is set for TwinRX currently?" post).
But maybe the daughterboards can be configured to use that reference clock.
Best Regards,

The LMK clock generator uses the reference clock from the mainboard, so
there should not be any mutual phase-jitter/drift issues. I can test this
on my N310 in the coming day or two.
What version of UHD is in use?
