GENERAL DESCRIPTION
The Realtek RTL8169SB(L) NIC Gigabit Ethernet controllers combine 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, 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 v2.3 and CardBus (RTL8169SBL only) bus interfaces for host communications with power management, and comply 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.
