I didn't see the spelling error in the datasheet.
I guess Microchip hires people who are challenged with the English language.
It is very much there and a para consisting of the term under query is quoted below. this extracted frompage 9(above the figure on left side) the datasheet link supplied by the O P.
"On the TPIN+/TPIN- and TPOUT+/TPOUT- pins,
1:1 center-taped pulse transformers rated for Ethernet
operations are required. When the Ethernet module is
enabled, current is continually sunk through both
TPOUT pins. When the PHY is actively transmitting, a
differential voltage is created on the Ethernet cable by
varying the relative current sunk by TPOUT+ compared
to TPOUT-."
Now I feel that the O P need not go for
Gardning as suggested. Finally I feel , let us go for the real issue where the O P needed help. Yes, spelling is important, no one denies it.
