2.7 PCIe Bus Components

2.7.1 PCIe Bus Overview

The PCIe bus is connected to components listed below:

Two PCIe GbE Broadcom LAN chipsets

One Mini PCIe socket

2.7.2 Broadcom PCI Express GbE interface

The BCM5787M Broadcom PCI Express (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

Wake on LAN support meeting the ACPI requirements

Statistics for SNMP MIB II, Ethernet-like MIB, and Ethernet MIB (802.3z,

clause 30)

Serial EEPROM or serial flash support

JTAG support

2.7.3 Mini PCIe

The Mini PCIe socket supports Mini PCIe cards that are compliant with PCI Express Base

Specification, Revision 1.0a. The Mini PCIe cards are easily installed into the socket. Mini

PCIe cards are 30mm wide, 50.95mm long and 5mm high and come with a single 52-pin

edge connector. Supported Mini PCIe components include wireless LAN cards,
