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.
YG GROUP supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
RTL8211FD(I)-CG is an authentic electronic component manufactured by Realtek, categorized under Communication & Networking ICs. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official RTL8211FD(I)-CG datasheet above.
Electronic component spot-market pricing for RTL8211FD(I)-CG fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.
Lead times for RTL8211FD(I)-CG depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
