RTL8110SC(L)
Datasheet

General Description
The Realtek RTL8110SC(L) LOM Gigabit Ethernet controller combines a triple-speed IEEE 802.3
compliant Media Access Controller (MAC) with a triple-speed Ethernet transceiver, 32-bit PCI bus
controller, and embedded memory. With state-of-the-art DSP technology and mixed-mode signal
technology, it offers high-speed transmission over CAT 5 UTP 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 device supports the PCI v2.2 and MiniPCI v1.0 bus interfaces for host communications with power
management, and is compliant with the IEEE 802.3 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.
To achieve the most efficient power management possible, Advanced Configuration and Power Interface
(ACPI) power management support is provided for modern operating systems that are capable of
Operating System directed Power Management (OSPM). PCI Message Signaled Interrupt (MSI) is also
supported.
In addition to the ACPI feature, the RTL8110SC(L) supports remote wake-up (including AMD Magic
Packet, Re-LinkOk, and Microsoft
®
Wake-up frame) in both ACPI and APM (Advanced Power
Management) environments. 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 RTL8110SC(L).
The RTL8110SC(L) is fully compliant with Microsoft
®
NDIS5 (IP, TCP, UDP) Checksum and
Segmentation Task-offload features, and supports IEEE 802 IP Layer 2 priority encoding and 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. 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 for server use, the RTL8110SC(L)
support the PCI Dual Address Cycle (DAC) command when the assigned buffers reside at a physical
memory address higher than 4 Gigabytes.
