Notes:
Value when driving into load impedance anywhere in the ZID range.
A transmitter should minimize ΔVOD and ΔVCMTX(1,0) in order to minimize radiation, and optimize signal integrity

Notes:
Applicable when the supported data rate <= 1.5 Gbps.
Applicable when the supported data rate > 1.5 Gbps.
Though no maximum value for ZOLP is specified, the LP transmitter output impedance shall ensure the TRLP/TFLP specification is met.
The voltage overshoot and undershoot beyond the VPIN is only allowed during a single 20 ns window after any LP-0 to LP-1 transition or vice versa. For all other situations it must stay within the VPIN range.
This value includes ground shift.
