Intel PCI-X manual Ethernet Controller Features, PCI Features, CSA Features 82547GI/EI Only

Introduction

For the 82544GC/EI, when connected to an appropriate SerDes, it can alternatively provide an Ethernet interface for 1000 Base-SX or LX applications (IEEE 802.3z).

Note: The 82546EB/82545EM is SerDes PICMG 2.16 compliant. The 82546GB/82545GM is SerDes PICMG 3.1 compliant.

82546GB/EB Ethernet controllers also provide features in an integrated dual-port solution comprised of two distinct MAC/PHY instances. As a result, they appear as multi-function PCI devices containing two identically-functioning Ethernet controllers. See Section 12 for details.

1.3Ethernet Controller Features

This section describes the features of the PCI/PCI-X Family of Gigabit Ethernet Controllers.
