(Refer to
The available bandwidth over a 2-lane HBR DisplayPort v1.1a link limits pixel clock rate
support to:
All supply pins can be tied to a single 3.3 V power source. Sufficient decoupling
capacitance to ground should be connected from each V
supply noise. (Refer to
We recommend the DAC outputs to use 75 Ω double termination.
example of VGA dongle application. A 75 Ω termination is used to terminate inside the
dongle, and another 75 Ω termination is typically used inside the RGB monitor. The load
sensing mechanism assumes this double termination.
