RTL8211FG(I)(-VS)-CG

The Realtek RTL8211FG-CG/RTL8211FG-VS-CG/RTL8211FGI-CG/RTL8211FGI-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 RTL8211FGI-CG and RTL8211FGI-VS-CG are manufactured to industrial grade standards.

The RTL8211FG(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 standards. 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 RTL8211FG(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 RTL8211FG(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 Gigabit Media Independent Interface (GMII) for 1000Base-T, 10Base-T, and 100Base-TX. The RTL8211FG(I)(-VS)-CG supports various RGMII/GMII signaling voltages, including 3.3, 2.5, 1.8, and 1.5V (only 3.3 and 2.5V are supported in GMII mode).
