概述和功能介绍
It is a highly integrated single chip for Giga 10/100/1000 Ethernet application. It is IEEE 802.3u/ab compliant single-port Giga Ethernet physical layer transceiver with low power consumption. It supports 10BASE-Te, 100BASE-TX, 1000BASE-T operation. GPHY connects the Media Access Control Layer (MAC) by GMII(Giga Media Independent Interface) or RGMII. it could support Un-shielded Twisted Pair Category 5 Cable(UTP5) for 100BASE-TX Fast Ethernet and 1000BASE-T Giga Ethernet, or UTP5/UTP3 cable for 10BASE-Te Ethernet. It contains the entire physical layer function of 100BASE-TX defined by IEEE802.3u and 1000BASE-T defined by IEEE 802.3ab, 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 GPHY also provides a robust auto-negotiation function, automatic media speed/duplex and protocol selection. GPHY also supports Auto MDI/MDIX function to simplify the network installation.
It also has a combined versatile MAC interface that is capable of interfacing with several controller interfaces. The 1000BASE-T transceiver includes PCS (Physical Coding Sublayer) Transmitter, PMA (Physical Medium Attachment) Transmitter, PMA Receiver and PCS Receiver.
