DP83825IRMQR - 10/100 Ethernet PHY | Texas Instruments
MPN: DP83825IRMQR ✓ פעילDP83825IRMQR סקירה
An Ethernet PHY transceiver is the physical-layer component that converts digital MAC data into signals suitable for transmission over copper cabling. Within the network hierarchy, the DP83825I belongs to the Ethernet physical layer and supports the IEEE 802.3 protocols identified in distributor and manufacturer listings. Its integrated PMD sublayers support both 10-Mbps and 100-Mbps operation, allowing a common physical-layer design to accommodate legacy and Fast Ethernet links.
The DP83825IRMQR combines a compact 3 mm by 3 mm footprint with low-power operation and a 50-MHz clock output. It supports Energy Efficient Ethernet, Wake-on-LAN, and MAC Auto-Disable according to the Texas Instruments product description. The 24-WQFN package also makes the device suitable for space-constrained equipment where a larger connector or magnetics section would be undesirable. An external Ethernet transformer remains required because the PHY does not connect directly to the medium.
The integrated 10BASE-Te and 100BASE-TX support covers Fast Ethernet links on CAT5e up to 150 meters. Full- and half-duplex modes provide deployment flexibility, while Energy Efficient Ethernet can reduce link activity when traffic is low. The 50-MHz clock output can support systems requiring a stable timing reference. These features place the device between an Ethernet MAC or embedded network controller and an external transformer-based copper interface.
Typical uses include compact industrial controllers, embedded Ethernet equipment, access points, network interface modules, and energy-conscious terminals. The small package is particularly useful in space-constrained embedded systems that still require a wired 10/100-Mbps connection. Wake-on-LAN support is useful in systems that must remain remotely wakeable, while MAC Auto-Disable can simplify power management where link state is not continuously required.
Designers should treat the external transformer, magnetic isolation, Ethernet magnetics layout, and connector interface as critical parts of the complete solution. Strapping resistors configure operating parameters, and the TI E2E support record specifically discusses the datasheet pull-up and pull-down values. Board layout should minimize high-frequency return paths and preserve the manufacturer-recommended separation between PHY, magnetics, and connector sections.
This page consolidates verified manufacturer, distributor, and cross-reference information with application guidance and source-linked design notes. It distinguishes documented capabilities from parameters that require confirmation in the current manufacturer datasheet, helping engineers evaluate the DP83825IRMQR without relying on unverified substitute claims.

יישומים טיפוסיים
DP83825IRMQR מתאים עבור 6 יישוםs: Compact Industrial Ethernet Controller, Energy-Efficient Network Terminal, Wake-on-LAN Embedded Device, Space-Constrained Network Access Module, Legacy 10/100-Mbps Equipment, Low-Power Networked Sensor Gateway.
Compact Industrial Ethernet Controller
The DP83825IRMQR fits compact industrial controllers that require a reliable 10/100-Mbps wired connection without allocating a large land pattern for the Ethernet PHY. Its 3 mm by 3 mm 24-WQFN package supports dense placement, while 10BASE-Te and 100BASE-TX compatibility allows the same design to address legacy and Fast Ethernet links. The external transformer remains part of the magnetic interface, and engineers must preserve the manufacturer’s recommended PHY-to-magnetics layout. Full- and half-duplex support provides deployment flexibility, although the exact MAC interface, strap configuration, and timing requirements should be confirmed against the current TI datasheet.
מומלץ
Energy-Efficient Network Terminal
The DP83825IRMQR is appropriate for terminals that benefit from Ethernet link power management because the manufacturer identifies Energy Efficient Ethernet and MAC Auto-Disable as supported features. These capabilities can help an embedded system reduce unnecessary network activity when traffic is light. The PHY still requires an external Ethernet transformer and careful magnetic layout. When designing the power policy, engineers should review the current datasheet for the exact operating states, enable sequencing, and interaction between MAC Auto-Disable, Wake-on-LAN, and the system’s host controller.
מומלץ
Wake-on-LAN Embedded Device
The DP83825IRMQR can serve in an embedded device that must remain remotely accessible through Wake-on-LAN support. It connects a 10/100-Mbps Ethernet MAC or host controller to twisted-pair cabling through an external transformer, creating a wired network path for remote activation. Designers should account for the 50-MHz clock output when defining host timing and verify the relationship among wake functionality, PHY configuration, and the host driver. Magnetics placement and isolation from noisy board regions are especially important in compact systems where the connector, transformer, and PHY must fit within limited board area.
מומלץ
Space-Constrained Network Access Module
The DP83825IRMQR is well suited to network access modules where every millimeter of board area affects the enclosure. Its 24-WQFN RMQ package measures only 3 mm by 3 mm and supports both 10BASE-Te and 100BASE-TX at up to 150 meters over CAT5e. That combination allows a small module to provide wired Ethernet without adopting a larger transceiver footprint. The module design must still reserve suitable space for the external transformer and Ethernet connector, so the apparent PHY miniaturization should not be confused with a smaller complete interface footprint.
מומלץ
Legacy 10/100-Mbps Equipment
The DP83825IRMQR supports equipment that must communicate over either 10-Mbps 10BASE-Te or 100-Mbps 100BASE-TX links. This dual-rate support is useful in industrial, building-access, and legacy industrial Ethernet environments where deployed cabling and attached devices may not consistently support newer Ethernet modes. The PHY implements the physical layer, while link negotiation and MAC behavior remain functions of the connected controller or driver. Full- and half-duplex support adds deployment flexibility, and the 50-MHz clock output helps engineers align the PHY with the host timing architecture.
מומלץ
Low-Power Networked Sensor Gateway
The DP83825IRMQR can provide wired connectivity for a low-power sensor gateway that cannot justify a Gigabit interface but still needs reliable 10/100-Mbps communication. Its low-power characterization, compact 3 mm by 3 mm package, and Energy Efficient Ethernet support make it relevant to embedded monitoring equipment. The gateway can use Wake-on-LAN for remote activation and MAC Auto-Disable to reduce activity when communication is unnecessary. A complete design must include the external transformer, suitable magnetic isolation, and a host interface whose driver supports the PHY’s documented configuration and clocking requirements.

מדריך בחירה
No genuine drop-in replacement was established from the verified cross-reference results, so do not substitute a generic 10/100 Ethernet PHY solely because its speed rating is similar. Any candidate should match the 24-WQFN RMQ land pattern, pin functions, register or host-driver expectations, clocking behavior, strap configuration, and power-management implementation. Use DP83825EVM for early evaluation when the transformer interface, board layout, or 10/100-Mbps operation needs validation. Before production release, verify the current TI datasheet for electrical limits, pin assignments, strap values, recommended capacitors, and layout geometry.

הערות תכנון
Treat the PHY, external transformer, and Ethernet connector as one controlled-impedance signal chain. Place the DP83825IRMQR and its required support components according to the current TI recommended layout, keep the media-side traces away from switching nodes and high-current paths, and avoid routing sensitive signals beneath the transformer or connector region. The verified sources confirm the need for an external transformer but do not reproduce the complete reference layout, so the manufacturer drawing must be used for exact spacing and routing.
Do not substitute strapping-resistor values based only on appearance or typical Ethernet practice. A verified TI E2E discussion specifically asks whether the datasheet’s 2.49-kΩ pull-up/pull-down values can be changed to 4.7 kΩ, which demonstrates that strap values affect PHY configuration. Follow the current manufacturer datasheet and account for host signals present during reset. The supplied search data does not contain the complete strap table, so an alternative value cannot be declared safe here.
Use the 50-MHz clock output only after confirming its source, enable conditions, load requirements, and intended use in the host timing architecture. Route clock traces away from transformer and connector fields, preserve return paths, and avoid unnecessary stubs. If the Ethernet magnetics and connector are also being designed, evaluate the complete channel and magnetics selection against the supported 10BASE-Te and 100BASE-TX modes rather than assuming that PHY substitution alone preserves signal integrity.
Define the PHY power sequence around the host MAC, external transformer bias requirements, and the system’s Energy Efficient Ethernet or MAC Auto-Disable policy. The verified manufacturer summary confirms those features but does not provide detailed rail sequencing or current limits. Use the current TI datasheet for operating voltages, shutdown behavior, and capacitor requirements, and validate the configuration during power-up rather than changing straps or timing on an assembled board.
