Texas Instruments DP83826E | Demoboard LAUNCHXL-F28P65X

Low latency 10/100-Mbps PHY with MII interface and enhanced mode

Overview

TopologyLAN / POE
Input voltage3.3 V
Output 13.3 V
IC revisionA

Description

The DP83826 offers low and deterministic latency, low power and supports 10BASE-Te, 100BASE-TX Ethernet protocols to meet stringent requirements in real-time industrial Ethernet systems. The device includes hardware bootstraps to achieve fast link-up time, fast link-drop detection modes and dedicated reference CLKOUT to clock synchronize other modules on the systems.The two configurable modes are BASIC standard Ethernet mode that uses a common Ethernet pinout, and ENHANCED Ethernet mode which supports standard Ethernet mode and multiple industrial Ethernet fieldbus applications with the additional features and hardware bootstraps configuration
