Description

The Realtek RTL8111E-VB-GR/RTL8111E-VB-CG/RTL8111E-VC-CG Gigabit Ethernet controller is an integrated electronic component that combines a triple-speed IEEE 802.3 compliant Media Access Controller (MAC) with a triple-speed Ethernet transceiver, PCI Express bus controller, and embedded memory. It uses state-of-the-art DSP technology and mixed-mode signal technology to offer high-speed transmission over CAT 5 UTP cable or CAT 3 UTP (10Mbps only) cable. The controller supports the PCI Express 1.1 bus interface for host communications and is compliant with the IEEE 802.3u specification for 10/100Mbps Ethernet and the IEEE 802.3ab specification for 1000Mbps Ethernet. It features embedded One-Time-Programmable (OTP) memory to replace the external EEPROM.
