RTL8212F/RTL8212G数据手册Realtek中文资料规格书

描述 Description

The RTL8212F/RTL8212G integrates dual independent gigabit Ethernet transceivers (PHY) and dual gigabit SerDes into a single IC. The device performs all the physical layer functions for 1000Base-T, 100Base-TX, and 10Base-T Ethernet on category 5 UTP cable, except 1000Base-T half duplex. 10Base-T functionality can also be achieved over standard category 3 or 4 cable.
With gigabit SerDes, the RTL8212F/RTL8212G also supports 1000Base-X/100Base-FX and it can be connected directly to a fiber-optical transceiver. The RTL8212F/RTL8212G supports fiber/copper dual media for combo link applications.
This device perform encoding/decoding, clock/data recovery, digital adaptive equalization, echo cancellers, crosstalk elimination, and line driver, as well as other required supporting circuit functions. An integrated internal hybrid allows the use of inexpensive 1:1 transformer modules. Each of the two independent transceivers features an industrial standard SGMII/RGMII/GMII/MII for glueless connection with Ethernet MACs. The two SerDes, acting as 1000Base-X/100Base-FX fiber ports, support SGMII/RGMII (RTL8212F) and SGMII/RGMII/GMII/MII (RTL8212G).
The RTL8212F/RTL8212G adopts mixed mode 0.13µm CMOS technology and analog line driver architecture, and is offered in thermally-enhanced 128/164-pin LQFP-EPAD packages. Enhanced ‘Green’ power-saving features allow very low power consumption.
