RTL8169S-32/RTL8169S-64
Datasheet
1. General Description
The Realtek RTL8169S-32 and RTL8169S-64 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 support an auxiliary power auto-detect function, and will auto-configure
related bits of the PCI power management registers in PCI configuration space.
They 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 RTL8169S-32 and RTL8169S-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. 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 RTL8169S-32 and RTL8169S-64.
The RTL8169S 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. The devices also 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 RTL8169S-32 and RTL8169S-64 support the PCI Dual
Address Cycle (DAC) command when the assigned buffers reside at a physical memory address higher
than 4 Gigabytes.
