RX DC differential mode impedance.
Required RX D+ as well as D- DC
Impedance (50 ± 20% tolerance).
Required RX D+ as well as D- DC

An unexpected Electrical Idle
(Vrx-diffp-p < Vrx-idle-det-diffp-p) must
be recognized no longer than
Trx-idle-det-diff-entertime to signal an
unexpected idle condition.
Skew across all lanes on a Link. This
includes variation in the length of SKP
ordered set (for example, COM and one
to five SKP Symbols) at the RX as well
as any delay differences arising from
the interconnect itself.
