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.
Depending on the operating mode of the remote link partner, the
received data is one of the following types of signals:
These signals interface directly to an isolation transformer, which in
turn, interfaces with the UTP cable.
Twisted-Pair Transmit (Data) Negative.
Within this table, see the description at pin 5, TP_TXP.
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:
These signals interface directly to an isolation transformer, which in
turn, drives the UTP cable.
