Note: Since some of the signal pins have different usages, the term “pin-compatible” is not applicable.
Introduction
Scope
Intel currently supports several footprint compatible Ethernet options depending upon the target
application. The term “footprint compatible” means that the silicon devices are all manufactured in
a 15 mm x 15 mm, 196-ball grid array package with the same ball pattern. Many of the critical
signal pin locations are identical, allowing designers to create a single LAN on Motherboard
(LOM) design that accommodates all devices. This is a flexible, cost-effective, multipurpose
design technique that allowing maximized value while matching performance needs.
Available LAN components with the same footprint include the 82547GI(EI) Gigabit Ethernet
Controller and the 82562EZ(EX) Platform LAN Connect components.
The LAN component used on a specific platform depends on the end user’s need for connection
speed and manageability. As the requirements change, footprint compatibility makes it possible to
re-focus the platform without the need to redesign a new a motherboard.
This application note contains Ethernet design guidelines applicable to LOM designs based on the
Intel
between the 82562EZ(EX) Platform LAN Connect device and the 82547GI(EI) Gigabit Ethernet
Controller.
Section 2 describes the port interfaces specific to each device.
Section 3 explains what you need to know to hook up an Ethernet device to the system.
Section 4 describes board layout techniques applicable to these devices.
Section 5 provides a reference to the design and layout checklists.
