DP83826E Datasheet Low-latency Low-power 10/100mbps Industrial Ethernet Phy

Manufacturer: Texas Instruments

Overview: DP83826E, DP83826I SNLS647G – DECEMBER 2019 – REVISED JULY 2023 DP83826 Deterministic, Low-Latency, Low-Power, 10/100 Mbps, Industrial Ethernet PHY.

General 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 tha
