We are investigating what appears to be a damaged PCIe input lane, PER_0_p and PER_0_n on the i350. The 100 Ohm (at DC) differential R is located on the die per the data sheet. With the i350 powered down, a differential Ohm measurement with a DMM simply reads as an open, ~ 11 M Ohm across PER_0_p and PER_0_n. Is the input AC coupled on the die, or is the 100 Ohm differential across PER_0_p and PER_0_n not realized until power is applied? Thanks.
