ADV7842 output data trace impedances

In both Hardware user guide and EVM, Output interface of ADV7842 is used 75ohm series resistors, and i found a note in HUG that trace impedance should be matched to series resistor selected. So are these signals need to be routed as 75ohm signals?

or can I use 22-33/49 ohm series resistor and route them as 50 ohm trace impedance?


Since IBIS model for this is not available.. it is been difficult to make a decision on this.

Please clarify me.
