Hi Chris,
Thanks for the link on the Uturn current.
Since Nikki has two VCC power planes. Can we minimize/avoid the effect
of U-turns by slicing=20
a portion of reference plane(wedge) just between the diff pairs and
having decaps for those power plans near the trace and void(GND
transition caps) this way there is no R-dash +/- currents we see R+/-
currents from TXr to Rxr. I anticipate R+/- to go from Vccplane1 to GND
through cap then from GND to VCC plane2.=20
I hope we have enough space between the pair so the individual trace
impedance is not affected w.r.t to it's reference.
Thanks
Senthil
