For the best transmission line signal integrity, the IC + the series resistor should equal the trace impedance.
As for the design of transmission lines for any board layer that is another question. Unless there is a specification for a type of signal like 60ohm memory, 90ohm USB, 109-118ohm SATA, etc., then there is no “must have” trace impedance number like 50ohm that you need to design into the board. What does matter to the transmission line is that the impedance does not vary from end to end. So if you are setting up a lot of 60ohm memory routes in your board. Set all to the traces to be 60ohm and adjust the value of the series resistors up so that drive impedance +series resistor equals 60ohm. And if the driver is 60 ohm, then you can save parts.
