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.
