Abstract

This application note outlines how Time Domain Reflectometry (TDR) helps solving various kind of cable fault challenges of Ethernet based communication systems. The application note describes the procedure to use TDR feature of the DP83867 and the DP83869 for implementing cable diagnostics feature in system.
