71 Voltage shown for PCIe* 2.5 GT/s and 5.0 GT/s are at the package pins (TP2).
72 For PCIe* at 2.5 GT/s and 5 GT/s, the VID is measured at TP2, which is the accessible test point at the device under test. For PCIe* 8.0 GT/s and 16.0 GT/s, the VID is measured at TP2P. TP2P defines a reference point that comprehends the effects of the behavioral Rx package plus Rx equalization and represents the only location where a meaningful eye height and eye width limits can be defined.
73 The maximum eye height value depends on the transmitter launch voltage maximum value. Refer to the PCIe* Express Base Specification Rev. 4.0 for the generator (TX) launch voltage value.
74 Connecting RESREF at 169 Ω calibrates PCIe* channel on-chip termination to 85 Ω.
