Pin Description
Twisted-Pair Receive (Data) Negative.
Within this table, see the description at pin 10, TP_RXP.
Twisted-Pair Receive (Data) Positive.
Data reception of differential analog signals occurs over the TP_RXN
and TP_RXP pair of differential-signal pins. Together these pins receive
the serial bit stream from the UTP cable through an isolation
transformer.
TP_TXN
TP_TXP
Depending on the operating mode of the remote link partner, the
received data is one of the following types of signals:
Two-level (10Base-T, that is, Manchester encoded) signals
Three-level (100Base-TX, that is, MLT-3 encoded) signals
These signals interface directly to an isolation transformer, which in
turn, interfaces with the UTP cable.

Output Twisted-Pair Transmit (Data) Negative.
Within this table, see the description at pin 5, TP_TXP.
5
Output Twisted-Pair Transmit (Data) Positive.
Differential analog signal transmission occurs over the TP_TXN and
TP_TXP pair of pins. Together these pins drive the serial bit stream
over the UTP cable.
Depending on the operating mode of the ICS1892 MDI, the
current-driven differential driver produces one of the following types of
signals:
Two-level (10Base-T, that is, Manchester encoded) signals
Three-level (100Base-TX, that is, MLT-3 encoded) signals
These signals interface directly to an isolation transformer, which in
turn, drives the UTP cable.
