ICH7-M PCIe Bus
The Intel® ICH7-M southbridge chipset has four PCIe lanes. Two of the four PCIe lanes
are interfaced to PCIe GbE controller. A third PCIe lane is interfaced to a PCIe mini
socket.
2.5.5.1 PCIe GbE Ethernet
Two PCIe lanes are connected to two Realtek RTL8111C PCIe GbE controllers shown in
711H
Figure 2-11 below.
Figure 2-11: Realtek PCI GbE Controllers
The Realtek RTL8111C PCIe GbE controllers combine a triple-speed IEEE 802.3
compliant Media Access Controller (MAC) with a triple-speed Ethernet transceiver, 32-bit
PCIe 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.
Some of the features of the Realtek RTL8111CP PCIe GbE controllers are listed below.
