Page 22
ƒ PCI Revision 2.3 compliant
ƒ 33 MHz
ƒ 5 V tolerant PCI signals (except PME#)
ƒ Integrated PCI arbiter supports up to seven PCI bus masters
2.5.7.1 PCI Edge Connector
The PCI interface is connected directly to the PCI portion of the edge connector on the
PCISA-945GSE.
2.5.7.2 ISA Edge Connector
The PCI interface is connected to the ISA edge connector through the iTE IT8888G
PCI-to-ISA chip.
2.5.8 PCIe Bus
The Intel® ICH7M provides four PCIe lanes. Some of these lanes are connected to the
components listed below:
ƒ Gigabit Ethernet Connector
The Gigabit Ethernet connections are shown in Figure 2-5.
2.5.8.1 Gigabit Ethernet Connector
Two of the four PCIe lanes on the Intel® ICH7M PCIe lanes are connected to the Realtek
RTL8111CP PCIe GbE controllers.
The Realtek RTL8111CP 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 (10 Mb/s 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.
