DP83822IRHBR - 10/100 Ethernet PHY, 16 kV ESD | TI
N.º de pieza: DP83822IRHBR ✓ ActivoDP83822IRHBR Descripción general
An Ethernet PHY transceiver converts between a device’s digital media-access-control interface and the analog signals carried over twisted-pair Ethernet cabling. The DP83822I belongs to the broader Ethernet physical-layer hierarchy: PHY transceiver, network interface IC, interface IC, and semiconductor. Placing the physical layer beside the network controller allows the controller to process frames while the PHY manages the electrical signaling and cable-side conditions.
The principal verified characteristics are 10/100-Mbps data-rate support, a 16-kV ESD rating, low-power operation, and a compact 32-VQFN 5.00 mm × 5.00 mm package. Texas Instruments describes the DP83822 as a feature-rich, pin-to-pin upgrade option for TLK105, TLK106, TLK105L, and TLK106L Ethernet PHYs. Those documented upgrade paths are more useful than a generic functional equivalent because they identify compatibility directly in the manufacturer’s support material.
The DP83822 architecture separates cable-facing analog functions from the digital MAC-facing interface. Its 10/100-Mbps capability is appropriate for links where 100 Mbps is sufficient and a gigabit PHY would add unnecessary cost, power, or board area. Programmable EEE and Wake-on-LAN support can reduce energy use when link activity is low, although system configuration determines when these modes are safe to enable.
Typical installations include industrial control terminals, factory automation equipment, embedded systems, USB-to-Ethernet adapters, set-top equipment, and network-interface cards. The small 5.00 mm × 5.00 mm VQFN package supports compact designs, but exposed-pad thermal management, controlled-impedance routing, isolated magnetics, and ESD-oriented layout remain essential for reliable field operation.
Designers should compare the DP83822 against the specific TLK105 or TLK106 family member used in the original design rather than treating every 10/100 PHY as interchangeable. Confirm the exact pinout, supported operating mode, clocking arrangement, strap configuration, and crystal or oscillator requirements against the manufacturer datasheet before production substitution. Ethernet magnetics and connector selection also affect the complete link budget.

Aplicaciones típicas
DP83822IRHBR es adecuado para 6 aplicacións: Industrial Automation Controllers, Embedded Network Equipment, USB-to-Ethernet Adapters, Network Interface Cards, Wake-on-LAN Endpoint Equipment, Set-Top and Network Appliances.
Industrial Automation Controllers
The DP83822IRHBR fits industrial automation controllers that require a 10/100-Mbps copper Ethernet link for configuration, telemetry, or service access. Its 16-kV ESD rating is particularly relevant to controller cabinets and factory environments, while the 32-pin 5.00 mm × 5.00 mm VQFN package preserves board area. The PHY can be paired with an existing Ethernet-capable MCU or application processor. Before production use, confirm the operating-temperature range, isolation strategy, magnetics, and connector requirements. Programmable EEE and Wake-on-LAN should be enabled only when the controlled equipment can tolerate link-state transitions during low-activity periods.
Recomendado
Embedded Network Equipment
The DP83822IRHBR provides a compact physical layer for embedded gateways, access units, and industrial IoT equipment operating at 10 or 100 Mbps. Its low-power design and programmable EEE, Wake-on-LAN, and other energy-saving modes can benefit intermittently connected systems. The 5.00 mm × 5.00 mm VQFN construction is useful where connector placement and enclosure space are constrained. Designers should use the manufacturer’s reference layout, preserve controlled impedance on the differential pairs, and provide a solid ground reference beneath the exposed pad. Confirm the required clock source, strap settings, and cable-side capacitors against the current datasheet.
Recomendado
USB-to-Ethernet Adapters
The DP83822IRHBR is appropriate for compact USB-to-Ethernet adapters requiring a robust 10/100-Mbps physical layer. Its documented 16-kV ESD protection adds useful interface margin for exposed USB-to-network products, although system-level protection must still include the connector and magnetics paths. The small 32-VQFN footprint can support dense dongle and embedded-adapter layouts. Designers should pay particular attention to USB-to-PHY clocking, the exposed-pad thermal path, and controlled-impedance routing. Since the target is limited to 100 Mbps, it is most appropriate where Gigabit throughput is unnecessary and lower power and board area are priorities.
Recomendado
Network Interface Cards
The DP83822IRHBR can serve as the Ethernet physical layer in a 10/100 network interface card connected to a suitable controller or system bus. Supporting both 10 Mbps and 100 Mbps allows interoperability with legacy and Fast Ethernet infrastructure, while the 16-kV ESD rating supports field-facing connector implementations. Its low-power operation may be advantageous in compact add-in or embedded cards. The 32-VQFN footprint still requires careful thermal-via placement and uninterrupted ground-plane geometry. Validate the card’s connector, isolation, magnetics, impedance, and regulatory requirements as a complete subsystem rather than judging PHY suitability from the IC specification alone.
Recomendado
Wake-on-LAN Endpoint Equipment
The DP83822IRHBR is suitable for endpoint equipment that must remain reachable through Wake-on-LAN while using less power during idle periods. Its verified Wake-on-LAN support, combined with 10/100-Mbps operation and 16-kV ESD protection, supports network-capable appliances and embedded products with controlled sleep behavior. The implementation must ensure that the host processor, Ethernet controller, and PHY power states cooperate correctly so that link pulses are not interrupted. Wake filtering, magic-packet handling, and system power rails are normally handled above the PHY. Validate the exact sleep and wake sequences in hardware because firmware and controller behavior determine practical latency.
Recomendado
Set-Top and Network Appliances
The DP83822IRHBR can provide a low-power 10/100-Mbps service connection in set-top boxes, network appliances, and management-oriented embedded products. Its compact 5.00 mm × 5.00 mm VQFN package leaves space for the processor and power circuitry in compact enclosures, and the 10/100-Mbps rate is adequate for control, management, or legacy uplinks. Programmable EEE can reduce link energy where traffic is intermittent. The design must still account for the exposed pad, Ethernet magnetics, connector geometry, and controlled-impedance PCB stack-up. Use the official footprint and reference layout to avoid soldering defects and signal-integrity degradation.

Notas de diseño
Use the Texas Instruments VQFN footprint and exposed-pad via arrangement rather than constructing it from the package dimensions alone. Place the PHY close to the Ethernet magnetics and connector, route the differential pairs as controlled-impedance nets, and provide a continuous ground reference. Avoid stubs and unnecessary test pads on the cable-side pairs. The exposed pad should connect to ground with the density and thermal capacity recommended in the package documentation.
Do not treat a same-package PHY as automatically interchangeable. The supplied TI cross-reference identifies DP83822 as a pin-to-pin upgrade from TLK105, TLK106, TLK105L, and TLK106L, but production conversion still requires checking power rails, strap states, clocking, LED behavior, interrupt polarity, and register compatibility. If the original design uses external magnetics or a nonstandard reference network, retain and validate those circuits against the DP83822 datasheet.
The 32-VQFN package has an exposed thermal pad, so thermal performance depends on the PCB copper and via array rather than only on the package outline. Keep the pad connected to a low-impedance ground plane and avoid placing a thermal isolation slot beneath it. Confirm actual junction and case temperature limits against the current manufacturer data. No verified junction-to-ambient thermal resistance was included in the supplied sources, so a numerical temperature-rise estimate should not be made from this page.
A 10/100 link still requires disciplined cable-side signal integrity, even though its data rate is modest. Keep the PHY, magnetics, and connector path compact; maintain the specified differential impedance; and provide the prescribed cable-side capacitors. The documented 16-kV ESD rating should not be treated as a substitute for external surge or ESD protection at exposed connectors. Validate the complete product against its applicable immunity and emissions requirements.
Información de cumplimiento
The supplied PartGenie component record identifies the DP83822IRHBR as RoHS compliant. The other compliance fields are unknown because no explicit supporting evidence was included. AEC-Q100 is marked not_applicable because this industrial Ethernet PHY is not identified as an automotive-qualified variant.
