PCIe expansion cards installed on the backplane communicate with the system through
the PCIe connector.
2.7.3 Broadcom PCIe GbE interface
The BCM5787M Broadcom PCIe GbE controller is a 10/100/1000BASE-T Ethernet LAN
controller. The BCM5787M combines a triple-speed IEEE 802.3 compliant Media Access
Controller (MAC) with a triple-speed Ethernet transceiver, a PCIe bus interface, and an
on-chip buffer memory. Some of the BCM5787 controller features are listed below:
Integrated 10/100/1000BASE-T transceiver
Automatic MDI crossover function
PCIe v1.0a
10/100/1000BASE-T full/half-duplex MAC
