Unless you don't need a particular input to output phase relation, they are "the same" - it doesn't matter which one is connected to N or P differential outpin pin.

Hi FvM,
Thanks a lot for your reply. The Balun unbalance port connect ceramic antenna, I don't find any phase requirement. So do you think I could ignore N, P pins connection.

Best Regards

yes, correct.
