10/100M Ethernet Transceiver

OverviewFeaturesRequest Datasheet

10/100M Ethernet Transceiver is an IEEE 802.3u compliant single-port Ethernet physical layer transceiver, and low power consumption transceiver for 10BASE-Te, 100BASE-TX, operation. Through the Giga Media Independent Interface (GMII), the EPHY connects to the Media Access Control Layer (MAC), and on the media side, it provides a direct interface either to Un-shielded Twisted Pair Category 5 Cable(UTP5) for 100BASE-TX Fast Ethernet or UTP5/UTP3 cable for 10BASE-Te Ethernet.

This EPHY employ a low power and high performance CMOS process. It contains the entire physical layer function of 100BASE-TX defined by IEEE802.3u, including the Physical Coding Sub-layer(PCS), Physical Medium Attachment Layer(PMA), Twisted Pair Physical medium Dependent Sub-layer (TP-PMD, 100BASE-TX only). The EPHY also provide a robust auto-negotiation function, utilizing automatic media speed/duplex and protocol selection match. EPHY also support Auto MDI/MDIX function to simplify the network installation.
