LCI Connection to 82562EZ(EX) Platform LAN Connect
Device
The 82562EZ(EX) Platform LAN Connect device uses the LAN Connect Interface (LCI) to
connect to the I/O Control Hub 5 (ICH5). LCI is a point-to-point interface optimized to support one
device.
Line termination mechanisms are not specified for the LCI. Slew rate controlled output buffers
achieve acceptable signal integrity by controlling signal reflection, undershoot and ringing.
For details about how to connect the LCI interface between the 82562EZ(EX) Platform LAN
Connect device and ICH5, please refer to the 82562ET/EM Platform LAN Connect Printed Circuit
Board (PCB) Design Guide, the Intel

guide.
