What is the internal resistance of the TJA1040T CAN transceiver?

Hi Supporter:

      What is the internal resistance of the TJA1040T CAN transceiver? I have checked the datasheet, it have two parameters(common-mode input resistance and differential input resistance).

      What is the understanding of this parameter in the red box below? Does it refer to the internal matching resistance of the CAN transceiver or the external one? What parameter does this percentage refer to?

1:Ri(cm) is resistance between input terminals and GND.

2: Ri(cm)m refers to typical 25K.

3: Ri(df) is resistance between two input terminals .
