USB 3.2 spec provides 2 sides (flip-flop side) data transfer path called 3.2x2 (10Gx2) and
USB 4.0 (20Gx2) following. However, it is challenged to implement the solution into a real
system because of 2 side signal request more circuits and PCB/A space. Therefore, it will
increase the system design complexity and cost either.
