RTL8111E

Datasheet

1. General Description

The Realtek RTL8111E-VL-CG Gigabit Ethernet controller 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. With state-of-the-art DSP technology and mixed-mode signal
technology, the RTL8111E offers high-speed transmission over CAT 5 UTP cable or CAT 3 UTP
(10Mbps only) cable. Functions such as Crossover Detection and Auto-Correction, polarity correction,
adaptive equalization, cross-talk cancellation, echo cancellation, timing recovery, and error correction are
implemented to provide robust transmission and reception capability at high speeds.

The RTL8111E supports the PCI Express 1.1 bus interface for host communications with power
management, and is compliant with the IEEE 802.3u specification for 10/100Mbps Ethernet and the IEEE

802.3ab specification for 1000Mbps Ethernet. It also supports an auxiliary power auto-detect function,
and will auto-configure related bits of the PCI power management registers in PCI configuration space.
The RTL8111E features embedded One-Time-Programmable (OTP) memory to replace the external
EEPROM (93C46/93C56/93C66).

Advanced Configuration Power management Interface (ACPI)—power management for modern
operating systems that are capable of Operating System-directed Power Management (OSPM)—is
supported to achieve the most efficient power management possible. PCI MSI (Message Signaled
Interrupt) and MSI-X are also supported.

In addition to the ACPI feature, remote wake-up (including AMD Magic Packet and Microsoft Wake-up
frame) is supported in both ACPI and APM (Advanced Power Management) environments. To support
WOL from a deep power down state (e.g., D3cold, i.e., main power is off and only auxiliary exists), the
auxiliary power source must be able to provide the needed power for the RTL8111E.

The RTL8111E is fully compliant with Microsoft NDIS5, NDIS6 (IPv4, IPv6, TCP, UDP) Checksum and
Segmentation Task-offload (Large send and Giant send) features, and supports IEEE 802 IP Layer 2
priority encoding and IEEE 802.1Q Virtual bridged Local Area Network (VLAN). The above features
contribute to lowering CPU utilization, especially benefiting performance when in operation on a network
server.

The RTL8111E supports Receive Side Scaling (RSS) to hash incoming TCP connections and
load-balance received data processing across multiple CPUs. RSS improves the number of transactions
per second and number of connections per second, for increased network throughput.

The RTL8111E supports Protocol offload. It offloads some of the most common protocols to NIC
hardware in order to prevent spurious wake up and further reduce power consumption. The RTL8111E
can offload ARP (IPv4) and NS (IPv6) protocols while in the D3 power saving state.

RTL8111E

The RTL8111E supports IEEE 802.3az Draft 3.0, also known as Energy Efficient Ethernet (EEE). IEEE

802.3az operates with the IEEE 802.3 Media Access Control (MAC) Sublayer to support operation in
Low Power Idle mode. When the Ethernet network is in low link utilization, EEE allows systems on both
sides of the link to save power.

The device also features inter-connect PCI Express technology. PCI Express is a high-bandwidth,
low-pin-count, serial, interconnect technology that offers significant improvements in performance over
conventional PCI and also maintains software compatibility with existing PCI infrastructure.

The RTL8111E is suitable for multiple market segments and emerging applications, such as desktop,
mobile, workstation, server, communications platforms, and embedded applications.
