ICS1893 Pin Descriptions
The tables in this section list the ICS1893 pins by their functional grouping.
9.3.1
Transformer Interface Pins
Table 9-2 lists the pins for the transformer interface group of pins.

TP_RXN
14
Input
Twisted-Pair Receive (Data) Negative.
Within this table, see the description at the TP_RXP pin.
TP_RXP
13
Input
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:
Two-level 10Base-T (that is, Manchester-encoded) signals
Three-level 100Base-TX, (that is, MLT-3 encoded) signals
The TP_RXN and TP_RXP pins interface directly to an isolation
transformer, which in turn, interfaces with the UTP cable.
TP_TXN
6
Output
Twisted-Pair Transmit (Data) Negative.
Within this table, see the description at the TP_TXP pin.
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 ICS1893 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-T (that is, MLT-3 encoded) signals
The TP_RXN and TP_RXP pins interface directly to an isolation
transformer, which in turn, drives the UTP cable.
