Application Note

DP838xx Wake-on-LAN

Abstract

Texas Instruments 10/100 Mbps family DP8382x (DP83822, DP83825, DP83826) and 10/100/1000 Mbps family DP8386x (DP83867 and DP83869) were designed to meet the needs of rugged and high performance applications while still offering a wide range of options for minimizing power consumption. This application note provides how these PHYs, referred to as DP838xx, Wake-on-LAN features work and how to implement each Wake-on-LAN mode.
