  • Hi Gareth,

    Please note some comments:

    1). PRSTN_n Signal: Typically we see pin this connected to the PCIe PRSNT1_n.

    2). There are both pull up and down on different options. We need to specify if we are going to install pull down or pull up. Typically we should start with minimum gain and no de-emphasis settings.

    3). We are assuming input A and input B have AC coupling Caps on TX that is attached to these ports.
