DS160PR412-421EVM: The PCIe Trace and Refclk trace Differential Impedance (85Ω or 100Ω) of the DS160PR412-421EVM Evaluation Module?

Fred Wu

Hi Sir

Could you check for me about the PCIe Trace and Refclk trace Differential Impedance (85Ω or 100Ω) of the DS160PR412-421EVM Evaluation Module?

Sincerely Yours!

This board was designed to use 100 ohm differential traces. It is recommended to use 85 Ohm differential traces in the actual design.

Confirmed! PCIe Trace trace Differential Impedance 85Ω in the actual design.

How about PCIe Refclk trace Differential Impedance (85Ω or 100Ω) in the actual design?
