PCI Revision 2.3 compliant
33 MHz
5 V tolerant PCI signals (except PME#)
Integrated PCI arbiter supports up to seven PCI bus masters
The PCI bus is connected to an interface gold finger on the bottom of the CPU card and
supports four expansion PCI cards on the backplane.

2.6.4.1 PCIe GbE

Two PCIe lanes are connected to two Broadcom BCM5787M PCIe GbE controllers shown
in Figure 2-13 below.

Figure 2-13: Broadcom BCM5787M GbE Controllers

The Broadcom BCM5787M PCIe GbE 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 (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 Broadcom BCM5787M PCIe GbE controllers are listed below.
