DP83826 Low-Latency Industrial Ethernet PHY with MII Interface and Enhanced Mode
Texas Instruments' low-power, 10/100 Mbps transceiver is compliant to IEEE802.3 10BASE-Te and 100BASE-TX standards
Texas Instruments' DP83826 low-latency physical layer (PHY) transceiver offers low and deterministic latency, low power, and support of Ethernet protocols including 10BASE-Te, 100BASE-TX 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 a 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 pin-out and ENHANCED Ethernet mode which supports standard Ethernet mode and multiple industrial Ethernet fieldbus applications with additional features and hardware bootstraps configuration.
