Regarding Driver Impedance

Hi Everybody,

 

Is the driver impedance of the IC  and the Characteristic impedance of board trace is having relation between them?

Suppose we have IMX6 IC which is having 34 ohm,40 ohm & 60 ohm driver impedance option and for our board we have

to maintain 50 ohn characteristic impedance for single ended lines ? which one of the Driver impedance of IC will be more

suitable for simulation.

 

Does these Driver impedance of IC and trace characteristic impedance holds any relation?

do we have to do like that Driver impedance of IC + Series Resistor = Trace characteristic impedance?

 

Kindly guide me.

 

Thanks & regards
