Review of DisplayPort Interface

Implications for Test

October 29, 2012

Confidentiality Label

Testing Main Link

There are hundreds of test conditions for DisplayPort Tx and a few for Dual Mode.

Must Activate Test Mode (Pattern, Bit rate, Level, Pre-emphasis control).

Different requirements for HBR2 than for HBR and RBR

Simulation of two cable models and CTLE Equalization

Different pattern, user choice on level/pre-emphasis, jitter measurement

Stressed Pattern Generation for Rx Test HBR and HBR2 different than RBR

Equalization used in calibration of stress (jittered) pattern.

Test AUX Physical Layer

Static measurements(DC) Probe Live Traffic condition

AUX Channel Control

Simulation of Link Training
