DP83826IRHBT - 10/100 Industrial Ethernet PHY | Texas Instruments
MPN: DP83826IRHBT ✓ نشطDP83826IRHBT نظرة عامة
An Ethernet PHY is the physical-layer component that translates digital MAC traffic into signals suitable for twisted-pair cabling and recovers those signals at the receiving endpoint. In the networking hierarchy, the DP83826IRHBT is a single-port Ethernet transceiver, placing it between a network media-access controller and the 100-MHz or 10-Mbps copper Ethernet medium. Its MII interface supports integration with conventional Ethernet controllers, while RMII provides a lower-pin-count alternative for suitable embedded processors.
Key characteristics include support for both 10BASE-Te and 100BASE-TX, a maximum link rate of 100 Mbps, deterministic low latency, low-power operation, and MII plus RMII interfaces. The industrial-temperature designation makes the device applicable to factory automation, industrial controls, embedded communications equipment, and other systems operating beyond typical commercial environments. The exposed-pad VQFN package also supports compact PCB layouts and improved thermal performance when the pad is connected to an appropriate ground plane.
The device is positioned for deterministic industrial Ethernet networks, where repeatable signal timing and predictable link behavior are important. The MII interface provides a parallel data path commonly used by Ethernet controllers, whereas RMII reduces the number of required interface signals when the host controller supports it. Auto-negotiation between 10-Mbps and 100-Mbps operation is part of the IEEE 802.3 feature set identified by the verified distributor data.
Typical uses include industrial Ethernet switches, programmable-logic-controller communication ports, industrial gateways, embedded control systems, and test equipment requiring a reliable copper-network interface. In these systems, the DP83826IRHBT can sit between an Ethernet MAC or processor and an isolated or non-isolated transformer-coupled network port, depending on the reference design and regulatory requirements.
Designers should confirm the exact pin functions, recommended magnetics, termination network, external clock requirements, exposed-pad layout, and bypass-capacitor values against the manufacturer data sheet before release. PCB signal-integrity and thermal reviews are particularly important because Ethernet PHY performance depends on controlled return paths and a low-impedance ground reference around the device.
This product page consolidates verified manufacturer and distributor information, drop-in alternatives supported by the supplied cross-reference results, comparison parameters, and practical design considerations for engineers evaluating the DP83826IRHBT.

التطبيقات النموذجية
DP83826IRHBT مناسب لـ 6 التطبيقs: Industrial PLC Ethernet Communication, Factory Automation Ethernet Gateway, Embedded Industrial Control System, Industrial Ethernet Switch Port, Machine Vision Network Interface, Test and Measurement Ethernet Front End.
Industrial PLC Ethernet Communication
The DP83826IRHBT fits industrial PLC and automation-controller designs requiring a deterministic 10/100-Mbps copper Ethernet interface. Its 10BASE-Te and 100BASE-TX support covers the two common 10BASE-Te and 100BASE-TX operating modes, while the MII interface can connect to a compatible Ethernet MAC. The industrial-temperature designation is useful when the controller is installed in a factory enclosure, although the complete enclosure temperature and power budget must still be verified. The 32-pin VQFN RHB package also helps maintain a compact controller layout. Designers should preserve the recommended return paths and place input, output, and reference decoupling close to the device.

Factory Automation Ethernet Gateway
The DP83826IRHBT is appropriate for an industrial gateway that bridges a machine or sensor network to a 10/100-Mbps copper Ethernet backbone. Its low-latency operation helps minimize transaction delay, while support for both 10BASE-Te and 100BASE-TX allows the link to operate within the speeds permitted by the connected infrastructure. The MII interface is appropriate when the host processor provides a parallel Ethernet MAC, and RMII may reduce host-side signal count where supported. Deployment near motors, relays, or long cable runs requires careful separation from switching noise and validated magnetics.
موصى به
Embedded Industrial Control System
The DP83826IRHBT supports embedded industrial control systems that require a compact, deterministic Ethernet network port. At up to 100 Mbps, it provides sufficient bandwidth for supervisory control, configuration traffic, and supervisory data exchange without requiring a 1000BASE-T PHY. The industrial-temperature grade is valuable in machinery and process-control equipment, while MII or RMII connectivity allows the design to align with the available controller interface. System-level validation should include cable insertion, impedance-controlled routing, magnetics selection, grounding, thermal performance at the exposed pad, and electromagnetic-emissions testing.

Industrial Ethernet Switch Port
The DP83826IRHBT can serve as the physical-layer device on a compact 10/100-Mbps industrial Ethernet switch port. It supports the two copper Ethernet rates associated with 10BASE-Te and 100BASE-TX and offers MII and RMII host connectivity for integration with switching silicon or an FPGA-based forwarding engine. The 32-pin VQFN package supports compact multi-port boards, although repeated PHY placement demands careful synchronization, return-path continuity, and thermal planning. For production equipment, validate link performance across temperature, cable length, radiated emissions, and conducted emissions using the manufacturer-recommended magnetic-interface network.
موصى به
Machine Vision Network Interface
The DP83826IRHBT is suitable for machine-vision controllers requiring a reliable 10/100-Mbps copper Ethernet connection to inspection equipment or a network server. The low-latency behavior supports responsive packet transfer, while dual-rate support accommodates legacy and 100-Mbps infrastructure. The MII interface can support a conventional MAC path when sustained image transfer requires deterministic parallel signaling. Camera and motor systems can be electrically noisy, so designers should isolate supply domains where appropriate, route Ethernet traces away from switching nodes, use manufacturer-recommended magnetics and terminations, and verify radiated emissions before production.
موصى به
Test and Measurement Ethernet Front End
The DP83826IRHBT can provide a network front end for industrial test and measurement equipment that exchanges commands, results, and firmware over copper Ethernet. Its support for 100 Mbps accommodates routine laboratory data transfer, while deterministic latency benefits supervisory workflows and automated test sequences. The MII interface permits direct attachment to a suitable Ethernet controller, and RMII can reduce host I/O when the embedded processor supports it. Instrument designs should evaluate EMI performance, isolated versus non-isolated network interfaces, chassis grounding, and the thermal path from the exposed pad. Final qualification should use the exact production magnetics and enclosure configuration.

ملاحظات التصميم
Route the Ethernet differential pair as a controlled-impedance pair with a continuous reference plane and minimize vias and stubs. Keep the PHY, magnetics, and termination network in the same signal region, avoid placing unrelated switching nodes beneath the pair, and maintain the ground reference around the 32-pin RHB package. Follow the current Texas Instruments layout and component-placement guidance because exact trace dimensions depend on the PCB stackup and whether the interface is isolated.
Place all required bypass capacitors at their designated PHY pins with short, low-inductance connections, and provide the supply current required for the selected 1.8 V or 3.3 V operating arrangement identified in the distributor data. Avoid sharing narrow supply paths between the PHY and noisy digital circuitry. Validate the capacitor voltage rating, DC-bias derating, and the complete power tree before schematic release because the supplied data does not include the detailed decoupling table.
Treat the exposed pad as a required thermal and electrical connection to the PCB ground plane. Follow the manufacturer land pattern, use adequate via arrays beneath the pad, and minimize thermal coupling from nearby regulators or processors. The supplied data confirms a 32-pin VQFN with an exposed pad but provides no junction-temperature, power-dissipation, or package thermal-resistance values, so a defensible junction-temperature estimate cannot be calculated from the available information.
Do not substitute DP83826IRHBT and DP83826ERHBT solely because their package and headline Ethernet data match. Verify operating-temperature limits, strap behavior, MII and RMII configuration, clock requirements, register compatibility, supported cable and magnetics, and lifecycle status in the applicable manufacturer data sheet. Also verify whether the board expects a pulse or pulse-transformer interface and whether isolation is required by the end-product safety architecture.
