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.
