AT91SAM9G45-EKES User Guide
Ethernet 10/100 (EMAC) Port
Figure 4-9.
The port is compatible with IEEE
The SAM9G45-EKES is equipped with a Davicom DM9161AEP 10/100 Mbps Fast Ethernet Physical
Layer TX/FX Single Chip Transceiver. It contains the entire physical layer functions of 100BASE-TX as
defined by IEEE 802.3u, including the Physical Coding Sublayer (PCS), Physical Medium attachment
(PMA), Twisted Pair Physical Medium Dependent Sublayer (TP-PMD), 10BASE-TX Encoder/Decoder
(ENC/DEC), and Twisted Pair Media Access Unit (TPMAU).
The Ethernet interface integrates an RJ45 connector with an embedded transformer, and three status
LEDs.
The Ethernet interface provides two selectable modes, MII or RMII (Reduced MII), for 100Base-Tx or
10Base-Tx. The MII and RMII interfaces are capable of both 10Mb/s and 100Mb/s data rates as
described in the IEEE 802.3u standard. The signals used by MII and RMII interfaces are described in the
table below.
