DP83826 Deterministic, Low-Latency, Low-Power, 10/100 Mbps, Industrial Ethernet PHY
The DP83826 offers low and deterministic latency,low power and supports 10BASE-Te, 100BASE-TXEthernet protocols to meet stringent requirements inreal-time industrial Ethernet systems. The deviceincludes hardware bootstraps to achieve fast link-uptime, fast link-drop detection modes and dedicatedreference CLKOUT to clock synchronize othermodules on the systems.
The two configurable modes are BASIC standardEthernet mode that uses a common Ethernet pinout,and ENHANCED Ethernet mode which supportsstandard Ethernet mode and multiple industrialEthernet fieldbus applications with the additionalfeatures and hardware bootstraps configuration.
