Notes:
  1. VAUX-DIFFp-p= 2*|VAUXP – VAUXN|
  2. Common mode voltage is equal to Vbias_​Tx (or Vbias_​Rx) voltage.
  3. Steady-state common mode voltage shift between transmit and receive modes of operation.
  4. Total drive current of the transmitter when it is shorted to its ground.
  5. All Display Port Main Link lanes as well as AUX CH must be AC coupled.
