Tool/software:
Hi,
We have used the above mentioned demultiplexer in our design so that based on selection line we can use Port A as USB3.1 and Port B as PCIE signals. We have interfaced SERDES 2 lanes(TX0,1 and RX0,1) from SOC to this demultiplexer as input signals. Here SERDES interface signals are pin muxed in SOC so we can configure these pins as either USB or PCIE. Provided snap as ref for single lane.
My question here is How can we route these 2 lanes(From SOC to demultiplexer) in the PCB as both interfaces have different trace impedances like for PCIE(85ohms) and USB3.1(90Ohms)? Please suggest how to route these signals on PCB?
