The Realtek RTL8111H-CG/RTL8111HS-CG 10/100/1000M 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 RTL8111H/RTL8111HS 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 RTL8111H/RTL8111HS supports the PCI Express 1.1 bus interface for host communications with
power management, and complies with the IEEE 802.3u specification for 10/100Mbps Ethernet and the
IEEE 802.3ab specification for 1000Mbps Ethernet. It supports an auxiliary power auto-detect function,
and will auto-configure related bits of the PCI power management registers in PCI configuration space.
The RTL8111H/RTL8111HS features embedded One-Time-Programmable (OTP) memory. The
RTL8111H provides a built-in LDO regulator, and the RTL8111HS provides a built-in switching
regulator.
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 RTL8111H/RTL8111HS. To
further reduce power consumption, the RTL8111H/RTL8111HS also supports PCIe L1.Off and
L1.Snooze.
The RTL8111H/RTL8111HS supports 'RealWoW!' technology that enables remote wake-up of a sleeping
PC through the Internet. This feature allows PCs to reduce power consumption by remaining in low
power sleeping state until needed.
Note: The 'RealWoW!' service requires registration on first time use.
The RTL8111H/RTL8111HS 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
RTL8111H/RTL8111HS can offload ARP (IPv4) and NS (IPv6) protocols while in the D3 power saving
state.
