1 Introduction

Texas Instruments Standard Ethernet PHY portfolio consists of various products. A key differentiator within the portfolio is the datarate each PHY is capable of. There are two classes of groups within the portfolio; 10/100/1000Mbps PHYs and 10/100 Mbps PHYs. DP83848 and DP83826A are two PHYs within the 10/100Mbps category and share common features aside from data rate such as select MAC interfaces, EtherCAT support, and LED control.

This document is inclusive of all versions of DP83848 and DP83826A. DP83848 is available in various temperature rated versions in addition to a second footprint. DP83826A is available in two temperature rated versions and has a ModeSelect pin which, depending on the applied voltage at power-on, can change the PHYs operation and pinout. However for this document, only Enhanced mode is discussed.
