General Description The Realtek RTL8211FD-CG/RTL8211FDI-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 RTL8211FDI-CG is manufactured to industrial grade standards. The RTL8211FD(I)-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 RTL8211FD(I)-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) for 1000Base-T, 10Base-T, and 100Base-TX. The RTL8211FD(I)-CG supports various RGMII signaling voltages, including 3.3, 2.5, 1.8, and 1.5V. The RTL8211FD(I)-CG incorporates a linear Low-Dropout Regulator (LDO) that features high power supply ripple rejection and low output noise. The built-in LDO means a power inductor is not required for the RTL8211FD(I)-CG; only an output capacitor is required between the 1.0V output and the analog ground for phase compensation, which saves cost and PCB real estate.
