3. As measured with compliance test load. Defined as 2*|V
4. COMP resistance must be provided on the system board with 1% resistors. COMP resistors are to V
5. PEG_ICOMPO, PEG_ICOMPI, PEG_RCOMPO are the same resistor. Intel allows using 24.9 1% resistors.
6. RMS value.
7. Measured at Rx pins into a pair of 50-terminations into ground. Common mode peak voltage is defined by
the expression: max{|(Vd+ - Vd-) – V-CMDC|}.
8. DC impedance limits are needed to ensure Receiver detect.
9. The Rx DC Common Mode Impedance must be present when the Receiver terminations are first enabled to
ensure that the Receiver Detect occurs properly. Compensation of this impedance can start immediately
and the 15 Rx Common Mode Impedance (constrained by RLRX-CM to 50  ±20%) must be within the
specified range by the time Detect is entered.
10. Low impedance defined during signaling. Parameter is captured for 5.0 GHz by RLTX-DIFF.
