Twisted-Pair Receive (Data) Negative.
Within this table, see the description at the TP_RXP pin.
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:
The TP_RXN and TP_RXP pins 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 the TP_TXP pin.
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 ICS1893Y-10 MDI, the
current-driven differential driver produces one of the following types of
signals:
The TP_RXN and TP_RXP pins interface directly to an isolation
transformer, which in turn, drives the UTP cable.
