ORX Internal LO and TX_LO effect TX EVM performance issue

What is the difference in TX output EVM, when you are configuring the ORX paths in internal LO vs ORX path with TX LO? Can you share plots?

when we used TX_LO mode symbol 0/1 EVM will worse to 10%, and when we switch ORX to internal_LO, the EVM down to <5%.
I only can test value in this web, I don't know how to share picture for you.

Are you using eval board or custom board? What is the TX LO frequency? 5% EVM is more and you should not get so high EVM. You should see ~1%EVM . TX EVM should not get impacted by the LO source. Can you check if the REF_CLK to the board is clean and jitter free? Also, check for its phase noise. Check the power supply, in case of a custom board.
