RTL8211FS(I)(-VS)-CG
INTEGRATED 10/100/1000M ETHERNET PRECISION TRANSCEIVER
General Description
The Realtek RTL8211FS-CG/RTL8211FS-VS-CG/RTL8211FSI-CG/RTL8211FSI-VS-CG is a highly integrated Ethernet transceiver that is
compatible with 10Base-T, 100Base-TX, and 1000Base-T IEEE 802.3 standards. It provides all the necessary physical layer functions to transmit
and receive Ethernet packets over CAT.5 UTP cable. The RTL8211FSI-CG and RTL8211FSI-VS-CG are manufactured to industrial grade
standards.
The RTL8211FS(I)-VS-CG provides full hardware support for high-precision clock synchronization based on the Precision Time Protocol (PTP) of
IEEE 1588 and 802.1AS standard. The integrated PTP functionality accurately timestamps each PTP packet on the Tx/Rx path, and the upper
layer software can use this timing information to determine the timing offset to the PTP master’s clock. The device also provides GPIOs as PTP
application interfaces.
The RTL8211FS(I)(-VS)-CG uses state-of-the-art DSP technology and an Analog Front End (AFE) to enable 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 RTL8211FS(I)(-VS)-CG to provide robust
transmission and reception capabilities at 10Mbps, 100Mbps, or 1000Mbps.
Data transfer between MAC and PHY is via the Reduced Gigabit Media Independent Interface (RGMII), or Serial Gigabit Media Independent
Interface (SGMII) for 1000Base-T, 10Base-T, and 100Base-TX. The RTL8211FS(I)(-VS)-CG supports various RGMII signaling voltages, including
3.3, 2.5, 1.8, and 1.5V.
The RTL8211FS(I)(-VS)-CG also supports a SerDes interface that can be configured as SGMII, 1000Base-X, or 100Base-FX.
