Preface

This manual is the primary reference for the Ethernet-1110 (E-1110) core.
The E-1110 includes the Media Access Controller (MAC) core for Gigabit
Ethernet, the Flow Control module for 10/100 Mbits/s Ethernet operation,
and a common Host Interface module that allows both the Gigabit MAC
and Ethernet-110 (E-110) core to interface to a host. The E-1110
provides a complete 10/100/1000 Ethernet MAC solution. The manual
also contains a functional description for the E-1110 core and complete
electrical and physical specifications. Details for E-110 core operation and
signals are found in the Ethernet-110 Core Technical Manual.

Audience

This manual assumes that you have complete familiarity with Ethernet
protocols and related support devices. It also assumes that you are
familiar with the IEEE 802.3 standard and all applicable clauses
describing Gigabit operation. The people who benefit from this manual
are:

Engineers and managers who are evaluating the E-1110 core for
possible use in ASIC applications

Engineers who are designing the E-1110 core into an ASIC.

Organization

This document has the following chapters:

Chapter 1, Introduction
