With RGMII\/GMII interface, EEE, Wake-on-LAN, and Green Ethernet features, it provides a complete Gigabit Ethernet physical layer in a compact QFN-48 package.","working_principle":"The RTL8211E implements 1000Base-T using 4D-PAM5 encoding over 4 pairs with DSP-based echo cancellation and crosstalk cancellation. The RGMII interface connects to the MAC layer with reduced pin count. Auto-negotiation determines best link speed. EEE reduces power during idle periods. The integrated switch regulator enables single-supply operation.","pin_description":"
