MPN: DP83822HRHBT ✓ NakahandaDP83822HRHBT Ulas
An Ethernet physical-layer transceiver, or Ethernet PHY, is the semiconductor interface between a digital network controller and physical communication media. Within the hierarchy of Ethernet interface ICs, a PHY converts parallel digital data into electrical signaling for copper cabling. The DP83822H family supports MII, RGMII, and RMII host interfaces and is designed for 10/100-Mbps industrial and embedded networks.
The device combines 10/100-Mbps data-rate support with a low-power design and programmable energy-saving functions. Energy Efficient Ethernet, Wake-on-LAN, and other programmable operating modes can reduce power consumption when the link is idle or the system is not actively communicating. Its robust electrical design and 16-kV ESD rating are particularly relevant to industrial environments where cables and ports can be exposed to electrostatic discharge.
The DP83822 uses a 32-pin VQFN package and is supported by the manufacturer datasheet as a pin-to-pin upgrade path for TLK105, TLK106, TLK105L, and TLK106L 10/100-Mbps Ethernet PHYs. The manufacturer also identifies an EtherCAT slave reference design using the DP83822H family, emphasizing its use in cost-optimized, high-EMC-immunity industrial Ethernet equipment.
Typical uses include industrial automation controllers, motor drives, embedded Ethernet gateways, factory communication equipment, and copper-to-fiber network bridges. The PHY can also serve designs requiring Wake-on-LAN, Energy Efficient Ethernet, or operation across the extended-temperature range stated for the DP83822H family.
Designers should treat the digital interface mode, magnetic-device selection, termination network, crystal or clock requirements, and PCB return paths as a complete PHY subsystem. Because exposed connector pins may receive electrostatic discharge, correct board grounding and cable-side protection remain important even though the integrated 16-kV ESD capability improves ruggedness.
This product page consolidates verified manufacturer and distributor facts into an engineer-oriented comparison of functionality, package, temperature capability, ESD protection, replacement options, and industrial Ethernet design considerations. It also distinguishes documented pin-compatible TI variants from unverified cross-brand alternatives, avoiding unsupported drop-in claims.

Tipikal na mga Gamit
DP83822HRHBT ay nararapat para sa 6 aplikasyons: Industrial Automation Controllers, Motor Drives and Factory Communication, Embedded Ethernet Gateways, Copper-to-Fiber Network Bridges, EtherCAT Slave Equipment, Low-Power Network Monitoring Equipment.
Industrial Automation Controllers
The DP83822HRHBT fits industrial automation controllers that require a 10/100-Mbps Ethernet port with strong electrostatic-discharge tolerance. Its 16-kV ESD protection and -40 °C to +125 °C extended-temperature range support equipment operating near motors, machinery, and unprotected field wiring. MII, RGMII, and RMII host-interface options provide integration flexibility, while Energy Efficient Ethernet and Wake-on-LAN can reduce consumption during idle periods. A design should still provide correct magnetic-device coupling, controlled return paths, and board grounding to realize the intended robustness.
Inirekomenda
Motor Drives and Factory Communication
The DP83822HRHBT is suitable for motor-drive controllers and factory communication equipment that exchange diagnostic and control data over 10/100-Mbps Ethernet. Its low-power operating modes help manage heat inside compact drive electronics, while the robust 16-kV ESD capability is valuable near industrial cabling. The PHY supports copper twisted-pair media directly and can work with an external fiber-optic transceiver where longer-distance links are needed. Layout should keep the PHY clock and digital interface paths away from switching nodes and motor-power stages.
Inirekomenda
Embedded Ethernet Gateways
The DP83822HRHBT can serve as the 10/100-Mbps Ethernet front end in an embedded gateway connecting a microcontroller or application processor to a local network. Its MII, RGMII, and RMII interfaces accommodate different host-controller architectures, and the 5.00 mm × 5.00 mm VQFN package supports compact PCB designs. Low-power modes are particularly useful in gateways that spend substantial time idle or monitoring network activity. Firmware must configure the selected interface, clocking mode, auto-negotiation behavior, and energy-saving features correctly.
Inirekomenda
Copper-to-Fiber Network Bridges
The DP83822HRHBT supports designs that combine a copper 10/100-Mbps Ethernet port with an external fiber-optic transceiver. This makes it appropriate for industrial links that require copper equipment compatibility on one side and optical distance or isolation on the other. The PHY’s MII, RGMII, and RMII options allow the bridge controller to select a suitable digital interface. Because the fiber transceiver is external, its electrical isolation, optics, power, and digital timing must be integrated carefully rather than treated as part of the DP83822 package.
Inirekomenda
EtherCAT Slave Equipment
The DP83822H family is explicitly associated with a cost-optimized, high-EMC-immunity EtherCAT slave reference design featuring dual ports and an SPI interface to an application processor. The DP83822HRHBT’s 16-kV ESD protection and extended-temperature operation align with the electrical environment of industrial EtherCAT equipment. For a new design, engineers should evaluate the complete TI reference design rather than treating the PHY datasheet alone as a complete EtherCAT solution. Magnetic-device selection, port isolation, firmware configuration, and EMC layout remain central to implementation.
Inirekomenda
Low-Power Network Monitoring Equipment
The DP83822HRHBT fits monitoring equipment that must maintain a 10/100-Mbps Ethernet connection while limiting power consumption. Wake-on-LAN can support remote activation, while Energy Efficient Ethernet and other programmable power-saving modes are useful for periodically active or duty-cycled systems. The compact 32-pin VQFN package also allows the PHY to be placed near the RJ45 and magnetic-device network for cleaner signal routing. Designers should verify that host firmware enables the required low-power states without preventing expected remote wake-up behavior.

Talaan ng Disenyo
Place the DP83822H PHY close to the RJ45 connector and magnetic-device network, then minimize the copper distance carrying high-speed differential signals. Provide a continuous reference plane and short return paths beneath signal pairs. Keep the digital host interface, clock source, and power connections away from the connector-facing network section. Although the PHY provides 16-kV ESD protection, the complete board still needs appropriate grounding and tested surge-path design.
Use the manufacturer-recommended power topology, decoupling capacitors, and magnetic-device configuration rather than treating the PHY as a standalone Ethernet connector interface. Configure the selected MII, RGMII, or RMII mode consistently in host firmware and verify clocking, reset, and strap settings against the datasheet. Energy Efficient Ethernet and Wake-on-LAN can reduce consumption, but each low-power state should be validated to avoid unintended loss of connectivity or remote wake-up operation.
Do not assume that a shared DP83822H ordering suffix guarantees identical software or production behavior. Before replacing DP83822HRHBT with DP83822IRHBT, DP83822HRHBR, or DP83822HFRBHT, compare the complete ordering tables, temperature grade, fiber options, firmware support, and packing information. In particular, the TI engineering discussion notes that the HFRBHT option adds fiber-signaling support and may involve software dependencies.
For industrial products, evaluate the Ethernet section as part of the system EMC design rather than relying only on the PHY’s 16-kV ESD rating. The manufacturer documents a high-EMC-immunity EtherCAT reference design, which provides a relevant starting point for port layout and filtering. Use controlled chassis and digital ground connections, place filtering near the external connector, and verify radiated and conducted emissions in the final enclosure and cable configuration.
