RTL8211CL-GR is a Gigabit Ethernet physical layer transceiver that is manufactured by Realtek. It is compatible with IEEE 802.3 standards, Ethernet standards and Gigabit Ethernet standards for 1000BASE-T, 100BASE-TX and 10BASE-T applications. It includes an integrated four-port Gigabit Ethernet PHY and a controller providing support for Auto MDI/MDI-X and Wake-on-LAN. This PHY consumes low power, reducing overhead costs and carbon emissions. RTL8211CL-GR features ECMA-312 and CE compliant integrated transformers that provide signal integrity and necessary bandwidth for Gigabit Ethernet. The device has auto-negotiation capabilities and supports Hot-plugging. It also provides a comprehensive MIB supporting SNMP management. The device is packaged in a 32-pin QFN package, offering increased power efficiency and reduced PCB size.
