Hello,
I used LMK04803 in my design of clock tree. But this is a general question, see below.
There are two signals: A and B. They have the same frequency, but different phase noise. On one branch, A and B mix directly and remove the carrier. But on the other branch, A mix with B after 180 degree phase shift. Then, the two output sum together. So, how should I calculate the phase noise of final output? Can they cancel each other?
