Note: The 40 rential reance seen by the TXU pins during normal operation. P leasesee Figure6 which shows a 12:transformer  
for the TXU pinsother side of a1:2transformer looks like a 25load to the TXU side of the transformer, the equivalent differential  
resistance seen = 10.5//Zc + 25 + 10.5//Zc ~= 40 where Zc is theimpedanceof the 1000 pf capacitors. For 10BASE-T  
frequenciesbetws impedance variesbetween 32 to 16 in // with the 10.5 resistors.
