Abstract

Texas Instruments offers a variety of Ethernet PHY transceivers which provide designs to multiple end equipment use cases. This application note references the differences between two of the PHYs within the 10/100Mbps portfolio (DP83826x(1) and DP83826Ax(2)) and how an existing design using DP83826x can be converted to use DP83826Ax.

  • DP83826x refers to DP83826E and DP83826I.
  • DP83826Ax refers to DP83826AI.
