Hi,
This idea may incur some controversial. Hope it's worthwhile.
It's like this:
In channel design, the optimal tline impedance actually depends on the fixed
impedances of TX, RX, and connector, etc. Through optimization you can locate
the best impedance for the trace, and it's not necessarily 85Ohm or 100Ohm. In
this case, to explore every cent of the system performance potential, should we
jump out of the frame of 85Ohm/100Ohm and choose to use other values?
