recently, we made the Xavier board and now finished to check functions,
so we will proceed the second PCB for end customer,
function and etc. no problem, but I want to improve design for performance.
we apply the 2 function SATA3 and 10G ethernet solution.
question is as bellow.
SATA3 PCIe trace
UPHY_TX0_P, UPHY_TX0_N, UPHY_RX0_P, UPHY_RX0_N = impedance 85ohm
Is this right? (ours first version is 100ohm, but no problem)
NVHS0_TX0_N, NVHS0_TX0_P, NVHS0_TX1_N, NVHS0_TX1_P, NVHS0_TX2_N, NVHS0_TX2_P, NVHS0_TX3_N, NVHS0_TX3_P… = impedance 85ohm
Are they some same impedance matching?
