The following is a detailed introduction to the RTL8211FDI-CG (Realtek High-Performance Gigabit Ethernet Transceiver), covering product description, features, technical specifications, and applications:
RTL8211FDI-CG Product Description
The RTL8211FDI-CG is a highly integrated Gigabit Ethernet physical layer transceiver (PHY) developed by Realtek Semiconductor, compliant with the 10Base-T, 100Base-TX, and 1000Base-T IEEE 802.3 standards. The chip is packaged in a QFN-40 package and supports an industrial-grade operating temperature range (-40°C to +85°C), making it suitable for industrial automation, smart terminals, and consumer electronics devices in harsh environments.
The RTL8211FDI-CG incorporates advanced DSP (digital signal processing) and AFE (analogue front-end) technologies, enabling high-speed data transmission via CAT.5 UTP cables. It also integrates features such as automatic crossover detection, polarity correction, adaptive equalisation, and crosstalk cancellation to ensure stable communication at 10Mbps, 100Mbps, and 1000Mbps data rates.
Mingjiada Electronics currently supplies the RTL8211FDI-CG with ample inventory, offering brand-new genuine products and supporting global procurement.
