The Realtek RTL8211E-VB-CG/RTL8211E-VL-CG/RTL8211EG-VB-CG are highly integrated Ethernettransceivers that comply with 10Base-T,100Base-TX, and 1000Base-T IEEE 802.3 standards.They
provide all the necessary physical layer functions to transmit and receive Ethernet packets over CAT.5 UTPcable.
The RTL8211E/RTL8211EG uses state-of-the-art DSP technology and an Analog Front End (AFE) toenable high-speed data transmission and reception over UTP cable.Functions such as Crossover Detection& Auto-Correction, polarity correction, adaptive equalization,cross-talk cancellation, echo cancellation,timing recovery, and error correction are implemented in the RTL8211E/RTL8211EG to provide robusttransmission and reception capabilities at 10Mbps，100Mbps,or 1000Mbps.
Data transfer between MAC and PHY is via the Reduced Gigabit Media Independent Interface (RGMII) orGigabit Media Independent Interface(GMII) for 1000Base-T,10Base-T, and 100Base-TX.The
RTL8211E-VB and RTL8211EG-VB support 3.3V or 2.5V signaling for RGMII/GMII. TheRTL8211E-VL supports 1.5v signaling for RGMII.
