SN74CBTLV3245A: 25M or 50M data rate system. When do the signal integrity simulation, whether they can use the on resistor 5ohm here?

Part Number:SN74CBTLV3245A

Hi team,

My customer wants to use the device in the 25M or 50M data rate system. When do the signal integrity simulation, whether they can use the on resistor 5ohm here?

In my opinion, it cannot, because the parallel cap will have smaller resistor than the Rdson 5ohm.

So which value we need to use in the simulation, or do we have the SI simulation module?

Thanks.
