RTL8110S-32/RTL8110S-64
Datasheet

General Description
The Realtek RTL8110S-32 and RTL8110S-64 LOM Ethernet controllers combine a triple-speed IEEE 802.3 compliant media
access controller (MAC) with a triple-speed Ethernet transceiver, 32(64*)-bit PCI bus controller, and embedded memory. With
state-of-the-art DSP technology and mixed-mode signal technology, they offer high-speed transmission over CAT 5 UTP cable
or CAT 3 UTP (10Mbps only) cable. Functions such as Crossover Detection & 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 devices support the PCI v2.2 bus interface for host communications with power management and are compliant with the
IEEE 802.3 specification for 10/100Mbps Ethernet and the IEEE 802.3ab specification for 1000Mbps Ethernet. They also
support an auxiliary power auto-detect function, and will auto-configure related bits of the PCI power management registers in
PCI configuration space.
They also support the Advanced Configuration and Power Interface (ACPI)--power management for modern operating systems
that are capable of Operating System directed Power Management (OSPM)--to achieve the most efficient power management
possible.
In addition to the ACPI feature, the RTL8110S-32 and RTL8110S-64 support remote wake-up (including AMD Magic Packet,
Re-LinkOk, and Microsoft
®
Wake-up frame) in both ACPI and APM (Advanced Power Management) environments. Also, the
LWAKE pin provides four different output signals including active high, active low, positive pulse, and negative pulse. The
versatility of the LWAKE pin provides motherboards with Wake-On-LAN (WOL) functionality. 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 RTL8110S-32 and RTL8110S-64.
The RTL8110S is fully compliant with Microsoft
®
NDIS5 (IP, TCP, UDP) Checksum and Segmentation Task-offload features,
and supports IEEE 802.1Q Virtual bridged Local Area Network (VLAN). The above features contribute to lowering CPU
utilization, especially benefiting performance when in operation as a server network card. Also, the devices boost their PCI
performance by supporting PCI Memory Read Line & Memory Read Multiple when transmitting, and Memory Write and
Invalidate when receiving. To better qualify as a server card, the RTL8110S-32 and RTL8110S-64 support the PCI Dual
Address Cycle (DAC) command when the assigned buffers reside at a physical memory address higher than 4 Gigabytes.
