8.5.1.2
Digital Display Interface (DDI) Signals DC Specification
NOTES:
1.
For embedded connection, support of programmable voltage swing levels is optional.
2.
Total drive current of the transmitter when it is shorted to its ground.
3.
Common mode voltage is equal to Vbias_Tx voltage shown in 
4.
Straight loss line between 0.675 GHz and 1.35 GHz.
5.
All DisplayPort Main Link lanes as well as AUX CH must be AC coupled. AC coupling capacitors must be 
placed on the transmitter side. Placement of AC coupling capacitors on the receiver side is optional.
