DP83822IFRHBR Visão geral
An Ethernet PHY transceiver is the physical-layer device in the Ethernet stack that converts digital MAC data into signals suitable for transmission over twisted-pair copper or optical fiber media. In the network hierarchy, the PHY sits between the Media Access Controller (MAC) and the physical medium, handling encoding, line driving, equalization, and link detection per the IEEE 802.3 10BASE-Te/100BASE-TX standards. Ethernet PHYs are foundational building blocks of industrial automation, factory networking, and connected embedded systems.
Key features of the DP83822IFRHBR include low power consumption enhanced by Energy-Efficient Ethernet (EEE), Wake-on-LAN (WoL), and programmable energy-saving modes; 16-kV system-level ESD robustness for harsh industrial environments; fiber-optic media support in the IF variant; and pin-to-pin upgradeability from the TLK105, TLK106, TLK105L, and TLK106L 10/100-Mbps Ethernet PHYs. These characteristics reduce system power budgets and improve reliability in electrically noisy installations.
Architecturally, the DP83822 integrates the analog line drivers, receivers, and adaptive equalization needed for robust 100BASE-TX links, together with a standard MII/RMII/SNI serial management interface for connection to virtually any MAC or FPGA-based MAC implementation. Programmable LED outputs, interrupt support, and extensive register-level configuration allow fine-grained control of link behavior and diagnostics.
Typical applications include industrial Ethernet nodes such as PLCs, motor drives, and I/O modules; building automation and security cameras; and general embedded networking where 10/100-Mbps connectivity, low power, and ESD robustness are required. The fiber-supported IF variant suits electrically hostile or long-distance links.
For design, provide a stable 3.3V supply domain with proper decoupling and follow TI's reference layout guidance for the magnetics and MDI routing to preserve signal integrity and ESD performance.

Aplicações típicas
DP83822IFRHBR é adequado para 6 aplicaçãos: Industrial Automation & PLC Networking, Motor Control Ethernet Nodes, Embedded Industrial Ethernet / IoT Gateways, Building Automation & Security Cameras, Fiber-Optic Industrial Links, Test & Measurement Instrumentation.
Industrial Automation & PLC Networking
The DP83822IFRHBR fits industrial automation nodes such as PLCs, remote I/O modules, and motor drives because its 16-kV ESD robustness and -40C to +85C industrial temperature rating directly address electrically noisy, thermally harsh factory-floor conditions. PartGenie lists Industrial Automation and Motor Control as its primary applications. In a typical node, the PHY sits between the MCU's MAC (via MII or RMII) and the RJ45 magnetics, delivering a robust 100BASE-TX link. EEE and programmable energy-saving modes cut rail power in always-on networks, while fiber support in the IF variant isolates long or high-noise cable runs.
Recomendado
Motor Control Ethernet Nodes
Variable-frequency drives and servo controllers increasingly require Ethernet connectivity for parameterization, diagnostics, and networked motion control. The DP83822IFRHBR's 16-kV ESD rating helps it survive the switching transients typical near power electronics, and its industrial temperature range matches drive enclosures. Connecting via RMII to the drive controller keeps the PHY interface low-pin-count, and EEE reduces standby consumption when the drive idles. Where cable runs traverse the full length of a machine or building, the IF variant's fiber support provides galvanic isolation against ground-potential differences between drive cabinets.
Recomendado
Embedded Industrial Ethernet / IoT Gateways
IoT gateways and embedded networking equipment use the DP83822IFRHBR to add a 10/100-Mbps port to microcontroller- or FPGA-based systems through its standard MII/RMII/SNI interfaces, which are supported by virtually every Ethernet MAC IP. Low power consumption - further reduced by EEE and Wake-on-LAN - suits battery-backed or thermally constrained enclosures. The 5x5 mm 32-VQFN conserves board area on compact gateway PCBs, and the 16-kV ESD rating reduces external protection components at the port. Programmable LED outputs give simple link and activity indication for field diagnostics.
Recomendado
Building Automation & Security Cameras
IP security cameras, access controllers, and building automation controllers require dependable 100-Mbps connectivity in environments with long cable runs and variable temperatures. The DP83822IFRHBR's robust line drivers with adaptive equalization maintain 100BASE-TX link integrity over category-5 cabling, while the -40C to +85C rating covers unconditioned spaces such as ceilings and outdoor junction boxes. Wake-on-LAN support allows cameras and controllers to be woken remotely for energy savings, and the 16-kV ESD rating protects against discharge events at exposed connectors during installation and service.
Recomendado
Fiber-Optic Industrial Links
The IF variant's fiber support makes this PHY suitable for Ethernet segments that must cross electrically hostile zones or exceed copper's 100-m limit - for example, links between plant buildings, near high-voltage equipment, or across areas with severe ground-potential differences. In such designs, the DP83822IFRHBR drives an optical module through the fiber media interface instead of copper magnetics, gaining galvanic isolation and immunity to induced surges that would corrupt copper signaling. The rest of the design flow - MII/RMII MAC connection, MDIO management, and LED diagnostics - is identical to copper deployments, easing design reuse.
Recomendado
Test & Measurement Instrumentation
Bench instruments and data-acquisition units use the DP83822IFRHBR to provide a standard 10/100-Mbps Ethernet port for remote control (SCPI-over-Ethernet), firmware updates, and data streaming. Its MII/RMII interface connects to the instrument's processor, and the standard MDIO register set is supported by common network stacks, shortening driver development. The 16-kV ESD robustness is valuable where users frequently connect and disconnect cables, and stable operation across -40C to +85C suits portable and benchtop instruments stored in unheated vehicles or warehouses.

Notas de projeto
Route the MDI differential pairs (TX+/TX-, RX+/RX-) from the DP83822IFRHBR to the magnetics as 100-ohm controlled-impedance pairs with matched intra-pair lengths, keeping them as short as possible and away from the RMII/MII digital lines. Follow TI's DP83822 reference design layout for the 32-VQFN (RHB) thermal pad - solder the exposed pad to a grounded copper pour for heat dissipation and return-path integrity, per the TI datasheet typical application.
Provide clean decoupling on each supply pin of the DP83822IFRHBR with 0.1-uF ceramics placed within a few millimeters of the pins, plus bulk capacitance near the PHY. Consult the exact supply domains (e.g., IO vs core rails) in the TI datasheet; supply values were not in the verified data for this page, so confirm them before finalizing the power tree. The PHY's low-power EEE modes reduce average rail current, but size the regulator for the full 100BASE-TX transmit worst case.
Keep the RMII 50-MHz reference clock trace short and route it as a single point-to-point connection with a clean ground return; RMII clock integrity is the most common cause of intermittent 100BASE-TX link failures with Ethernet PHYs. Add series termination if the clock driver is far from the PHY. Minimize stubs on the MII/RMII bus and match trace lengths within the bus group where practical.
When migrating from TLK105/TLK106 to the DP83822IFRHBR on the same footprint, update the software MDIO configuration: the DP83822 adds EEE and WoL registers and may differ in register map details versus the TLK predecessors. Also note that the -F (IF) variant enables fiber support while the IR variant does not - confirm which variant your BOM intends before ordering, since the suffix affects functionality even though the package footprint is identical.
