V_TX-DIFFp-p = 2*|V_TX-D+-V_TX-D-|
See Note 1.
This is the ratio of the V_TX-DIFFp-p of the
second and following bits after a
transition divided by the V_TX-DIFFp-p of
the first bit after a transition
See Note 1.
V_TX-CM-ACp = |V_TX-D+ + v_TX-D-| / 2 – v_TX-
CM-DC
v_TX-CM-DC = DC_(avg) of |V_TX-D+ + V_TX-D-|
/ 2 ^{during L0}
See Note 1.

V_{TX-CM-DC =} DC_(avg) of |V_TX-D+ + V_TX-D-|
/ 2 [electrical idle]
