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.
