Hi Sir,
My customer is using the DS160PT801 on the 4-lane PCIe design.
May I know if the unused pin-out can be floating?
Please also check the lane trace on the schematics to ensure it is correct. Thanks!

Hi Henry,
Unused pins can be left floating.
Please ensure the Tx outputs of the retimer have ac-coupling caps present.
