3 Description

The DP83826Ax 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.
