DP83826ERHBT - 100Mbps Industrial Ethernet PHY | Texas Instruments
MPN: DP83826ERHBT ✓ ActiveDP83826ERHBT Overview
An Ethernet PHY is a physical-layer semiconductor that translates digital MAC data into signals suitable for twisted-pair cabling and recovers incoming signals for the network controller. Within the hardware hierarchy, the DP83826ERHBT is an interface IC, network interface controller, Ethernet transceiver, and physical-layer PHY. It connects an Ethernet MAC or embedded processor to a 10BASE-Te or 100BASE-TX network while supporting both MII and RMII host interfaces.
The device is designed around predictable industrial-network behavior rather than only conventional throughput. Its low and deterministic latency supports real-time Ethernet systems, while low-power operation helps control system demand. Hardware bootstraps support fast link-up times, and configurable fast link-drop detection modes can improve recovery after network disturbances. The dedicated reference clock output provides a convenient synchronization source for modules elsewhere in the system.
The DP83826E family supports 10-Mbps and 100-Mbps Ethernet operation for industrial automation, factory equipment, networking equipment, embedded control, communications infrastructure, and test systems. Its MII interface suits designs requiring parallel digital signaling, while RMII reduces host pin requirements in compact embedded designs. The enhanced operating mode provides additional configuration options for demanding industrial applications.
A primary design consideration is the relationship between PHY configuration, MAC timing, magnetic-interface components, and the industrial network topology. The PHY must be matched to the magnetics and cabling environment, while reset, interrupt, reference-clock, and strap configuration must be reviewed against the host processor power-up sequence. Controlled impedance routing and a suitable low-noise supply arrangement are also important for maintaining reliable data transmission.
This page combines verified manufacturer and distributor information, package details, commercial availability, drop-in family alternatives, and application-oriented engineering guidance. It distinguishes verified facts from unavailable values so designers can identify where a datasheet review, PCB footprint check, or component-level cross-reference is still required before release to manufacturing.

Typical Applications
DP83826ERHBT is suitable for 6 applications: Industrial Automation Controllers, Factory Sensor and Gateway Equipment, Real-Time Network Switches, Embedded Control Platforms, Communications and Networking Equipment, Test and Measurement Instruments.
Industrial Automation Controllers
DP83826ERHBT fits industrial automation controllers that need deterministic 10/100-Mbps Ethernet behavior. Its low-latency architecture supports time-sensitive communication, while hardware bootstrap enables rapid link establishment after system startup or network disturbance. Fast link-drop detection modes can improve recovery in factory networks where cable movement, switching events, or equipment resets are common. The device connects the controller through MII or RMII and supports both 10BASE-Te and 100BASE-TX links. Designers should pair it with a properly selected Ethernet magnetic interface and verify the host clocking, reset sequencing, and strap configuration against the manufacturer datasheet.
Recommended
Factory Sensor and Gateway Equipment
DP83826ERHBT can provide the wired Ethernet connection for sensor gateways, data concentrators, and remote industrial monitoring units. Its support for 10-Mbps operation allows links to coexist with legacy 10BASE-Te equipment, while 100BASE-TX provides higher bandwidth when supported by the network. Low-power operation is valuable in embedded equipment, and the dedicated reference CLKOUT can support clock distribution within the module. The design must still account for surge, magnetic-interface selection, cable routing, and thermal conditions in industrial cabinets because those environmental ratings are not fully present in the supplied source snippets.
Recommended
Real-Time Network Switches
DP83826ERHBT is suitable for real-time Ethernet switch and interface modules requiring a 10/100-Mbps copper PHY with predictable link behavior. Hardware bootstrap supports fast link-up during equipment initialization, and configurable fast link-drop detection can help the host react promptly to a failed port. The dedicated reference clock output may assist synchronization across switch modules. A production design should evaluate recovery behavior, error handling, and the exact MII timing configuration in the manufacturer datasheet, while also confirming how the PHY integrates with the switch ASIC and magnetics used on the selected board.
Recommended
Embedded Control Platforms
DP83826ERHBT gives an embedded processor platform a dedicated Ethernet physical layer while leaving frame handling to the host MAC. The RMII option can simplify connections to controllers designed around a compact parallel bus, whereas MII provides a more parallel and widely supported host interface. Low-power operation and support for both 10BASE-Te and 100BASE-TX are useful in industrial embedded systems. The host must meet the required reference-clock and reset timing, and the PCB must implement the manufacturer-recommended magnetic and decoupling network to preserve signal integrity and link reliability.
Recommended
Communications and Networking Equipment
DP83826ERHBT can be used in network-interface modules, communication gateways, and industrial Ethernet equipment that need a reliable 10/100-Mbps copper connection. Its low deterministic latency is relevant to traffic that cannot tolerate unpredictable recovery delays, and fast link-up supports rapid equipment initialization. The reference CLKOUT provides a dedicated output for synchronizing neighboring modules. When integrating the PHY, engineers should validate the chosen Ethernet transformer or integrated magnetics, controlled-impedance traces, isolation boundaries, and reset behavior because those implementation details determine whether the electrical and timing targets are maintained in the final system.
Recommended
Test and Measurement Instruments
DP83826ERHBT is applicable to test and measurement equipment that transfers operational data over a 10/100-Mbps Ethernet control link. The deterministic-latency positioning can help separate network timing from the behavior being measured, while fast link-drop detection gives the instrument a rapid indication of connection loss. The dedicated clock output can support synchronization within the instrument. For laboratory equipment, designers should still verify conducted-noise margins, grounding, isolation, and enclosure-related thermal conditions because the verified data identifies the industrial Ethernet role but does not provide complete EMC or environmental ratings.

Design Notes
Review the complete 32-VQFN land pattern and the manufacturer's recommended component placement before routing the Ethernet interface. Keep the PHY clock, MII or RMII signals, and supply connections short, and use a continuous ground reference beneath the exposed pad. The verified snippets identify the 5 x 5 mm VQFN package but do not provide the numbered pin table or escape-routing guidance, so the official datasheet must govern pad geometry and fanout.
Design the 10BASE-Te and 100BASE-TX copper channel around the magnetics selected for the product. Maintain controlled impedance for the differential pairs, provide an uninterrupted return path, and separate switching or high-current nodes from the Ethernet traces. The PHY's low deterministic latency cannot compensate for signal degradation, reflections, or poor return-path continuity introduced by the PCB and cabling system.
Confirm the DP83826E family's required supply voltages, sequencing, and decoupling values from the manufacturer datasheet before finalizing the power tree. Host, PHY, and magnetics supplies may require coordinated startup to prevent incorrect strap sampling or unstable clocking. Use the dedicated CLKOUT only within the clock scheme allowed by the datasheet, because distributing an unsuitable reference to unrelated loads can affect signal integrity.
Do not treat a shared 32-VQFN family suffix as proof that every orderable variant is a drop-in replacement. The verified comparison data identifies DP83826ERHBR, DP83826IRHBT, and DP83826IRHBR as close family candidates, but it does not fully quantify temperature grade, qualification, production configuration, strap, or electrical differences. Check the official ordering table, pin table, absolute maximum ratings, and lifecycle status before substituting any MPN on an existing PCB.
Compliance Information
The supplied product snippets do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred from the manufacturer or package family.
