Texas Instruments DP83826 10/100Mbps PHY

Texas Instruments DP83826 10/100Mbps PHY offers low and deterministic latency and low power and supports 10BASE-Te, 100BASE-TX Ethernet protocols. These features help meet stringent requirements in real-time industrial Ethernet systems. The Texas Instruments DP83826 includes hardware bootstraps for fast link-up time, fast link-drop detection modes, and dedicated reference CLKOUT to clock synchronize other system modules. The two configurable Ethernet modes are BASIC standard Ethernet and ENHANCED Ethernet. BASIC standard Ethernet mode uses a common Ethernet pinout. ENHANCED Ethernet mode supports standard Ethernet mode and multiple industrial Ethernet Fieldbus applications with additional features and hardware bootstrap configuration.
