Dear TI Team:

We have DS80PCI102SQ/NOPB in our design,

Which is in the middle of CPU chip and I210 chip (OOB ethernet controller), PCIe GEN 1.

Both chip are on PCB board,no cable, all are trace on PCB

1. Pls help review the SCH attached,Thanks

2. Could you explain more detail how to connect Pin_RXDET and SD_TH?

3. The overall PCIe trace impedance will be 85ohm differential, is is ok?

Hi Lisa,

I believe this is the same project as the following E2E thread. I will review the schematic and provide feedback on this thread by the end of this week.
