Insertion loss budget on PCB - PCIe Gen 3 Posted byjoniengr081on 03 Jan, 2024 09:15
I found this article which deals with the insertion loss budget for PCIe. I am looking for the table in which the total channel insertion loss budget for PICe Gen 3 (8 GT/s) is 22 dB which is distributed as Root Package (3.5 dB), CEM Connector (1.7 dB), Add-in Card (6.5 dB), Remaining Budget for System Base Board (10.3 dB).
Remaining Budget for System Base Board (10.3 dB): Is that the budget for PCB design ? Does it means that the PCB traces should not have more then 10.3 dB insertion loss ?
