Introduction

The 82566 is a single port Gigabit Ethernet Physical Layer Transceiver (PHY) that connects to its

MAC through a dedicated interconnect. The 82566 is based on Intel's Gigabit PHY technology, and

supports operation at data rates of 10/100/1000 Mbps. The physical layer circuitry provides a

standard IEEE 802.3 Ethernet interface for 10BASE-T, 100BASE-TX, and 1000BASE-T

applications (802.3, 802.3u, and 802.3ab).

This device operates with the ICH8/ICH9 chipset that incorporates and integrates the media access

controller (MAC), which is referred to as the ICH8/ICH9 LAN.

The 82566 is packaged in a small footprint flip chip molded matrix array package (FCMMAP)

with 81 balls in a 9 x 9 array. The package size is 10 mm x 10 mm with a pitch of 1.0 mm, making

it attractive for small form-factor platforms.

The device interfaces with its MAC through two interfaces: Gigabit LAN Connect Interface

(GLCI) and LAN Connect Interface (LCI). The GLCI is a high speed proprietary serial interface.

The LCI is a low speed proprietary parallel bus. The 82566 operates using both interfaces; the

GLCI for 1000 Mbps traffic and LCI for all other traffic types.

Figure 1 identifies the major components of the 82566 architecture.
