RTL8211F-CG Datasheet – Ethernet Transceiver
INTEGRATED 10/100/1000M ETHERNET TRANSCEIVER
RTL8211F-CG overview
The RTL8211F-CG is an INTEGRATED 10/100/1000M ETHERNET TRANSCEIVER made by Realtek, supplied in a QFN 40 Pin Type package. The absolute maximum ratings table on this page lists the 8 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the RTL8211F-CG pinout and maximum ratings, with the full datasheet PDF to preview below or download.
The Realtek RTL8211F-CG/RTL8211FD-CG/RTL8211FI-CG/RTL8211FDI-CG is a highly integrated Ethernet transceiver that complies 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 RTL8211FI and RTL8211FDI are manufactured to industrial grade standards.
The RTL8211F(I)/RTL8211FD(I) 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 RTL8211F(I)/RTL8211FD(I) 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) for 1000Base-T, 10Base-T, and 100Base-TX. The RTL8211F(I)/RTL8211FD(I) supports various RGMII signaling voltages, including 3.3, 2.5, 1.8, and 1.5V.

RTL8211F-CG pinout
| Pin | Name | Description |
|---|---|---|
| 1 | MDIP0 | In MDI mode, this is the first pair in 1000Base-T, i.e., the BI_DA+/- pair, and is the transmit pair in 10Base-T and 100Base-TX. In MDI crossover mode, this pair acts as the BI_DB+/- pair, and is the receive pair in 10Base-T and 100Base-TX. |
| 2 | MDIN0 | |
| 4 | MDIP1 | In MDI mode, this is the second pair in 1000Base-T, i.e., the BI_DB+/- pair, and is the receive pair in 10Base-T and 100Base-TX. In MDI crossover mode, this pair acts as the BI_DA+/- pair, and is the transmit pair in 10Base-T and 100Base-TX. |
| 5 | MDIN1 | |
| 6 | MDIP2 | In MDI mode, this is the third pair in 1000Base-T, i.e., the BI_DC+/- pair. In MDI crossover mode, this pair acts as the BI_DD+/- pair. |
| 7 | MDIN2 | |
| 9 | MDIP3 | In MDI mode, this is the fourth pair in 1000Base-T, i.e., the BI_DD+/- pair. In MDI crossover mode, this pair acts as the BI_DC+/- pair. |
