89 For PCIe* at 2.5 GT/s and 5 GT/s, VID is measured at TP2, which is the accessible test point at the device under test. For PCIe* and CXL 8.0 GT/s, 16.0 GT/s and 32.0 GT/s, 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.
90 85ohms (Typical) aligned to Base spec.
91 Connecting RCOMP at 150 Ω calibrates PCIe* and CXL channel on-chip termination to 85 Ω (aligned to Base spec).
