8.3 ICS1893CY-10 Pin Descriptions
8.3.1 Transformer Interface Pins
ICS1893CY-10 Rev 1/07
The tables in this section list the ICS1893CY-10 pins by their functional grouping.
Transformer connections on the ICS1893CY-10 signals TP_AP, TP_AN, TP_BP and TP_BN are shown in
Table 8.2. The previous TP_CT pin on the ICS1893AF is not used with the ICS1893CY-10. The typical
Twisted Pair Transformers connections are shown in Chapter 5. The transformer must be 1:1 ratio and
symetrical for 10/100 MDI/MDIX applications since the transmit twisted pair and receive twisted pair are
interchangeable. ICS1893 PHYs do not have power connections to the transformer. All transformer power
is supplied by the ICS1893. Note the twisted pair are polarity sensitive and must connect to the RJ45 with
the same polarity as shown in the figure.
