DP83815DUJB - 10/100 Ethernet PCI MAC/PHY | Texas Instruments
Teilenummer: DP83815DUJB ✗ AbgekündigtDP83815DUJB Übersicht
An Ethernet MAC/PHY is a controller that connects a computer or embedded system to twisted-pair Ethernet media. The MAC subsystem handles frame processing and the host interface, while the PHY converts digital data into signals suitable for 10BASE-T or 100BASE-TX links. Integrating both functions reduces the number of discrete interface components, although magnetics, termination, clocking, decoupling, and a compatible driver remain necessary around the IC.
The DP83815DUJB provides full-duplex operation, IEEE 802.3x flow control, VLAN support, and long-frame support. Its PCI interface makes it relevant to legacy PCI systems and embedded platforms whose host bus requires the DP83815 rather than a modern PCIe Ethernet controller. The integrated physical layer supports both 10BASE-T and 100BASE-TX connectivity, allowing negotiation between 10 Mbps and 100 Mbps links.
Technically, the device combines protocol handling, media access, and physical-layer signaling in one silicon implementation. A typical implementation places the controller beside an Ethernet transformer and RJ-45 connector, with short differential traces routed as controlled-impedance pairs. The 15 mm by 15 mm LBGA also demands careful escape routing because its 160-pin arrangement provides no perimeter leads. Supply and return distribution must therefore be planned as part of the high-speed mixed-signal layout.
Typical applications include legacy industrial controllers, PCI-based embedded systems, embedded test equipment, data-acquisition systems, and industrial networking adapters that require 10/100 Mb/s Ethernet. Its 0 °C to +70 °C range is appropriate for commercial equipment, while the PCI host interface limits its usefulness in new designs centered on compact embedded processors or modern personal computers.
Designers should verify the complete pinout, reference circuit, clock requirements, and PCI electrical characteristics against the manufacturer datasheet before layout. Because the DP83815DUJB is identified as obsolete in the supplied cross-reference results, repair and maintenance demand careful sourcing, while new designs should confirm whether a currently supported controller offers a more practical interface, package, and availability profile.
This page consolidates the verified supplier specifications, lifecycle evidence, replacement search results, package constraints, and engineering guidance into one selection reference. It also distinguishes verified drop-in evidence from broader Ethernet-controller alternatives, helping engineers avoid treating electrically similar devices as PCB-compatible replacements.

Typische Anwendungen
DP83815DUJB ist geeignet für 6 Anwendungs: Legacy PCI Network Adapter, Industrial Control Ethernet, Embedded Data Acquisition System, Industrial Networking Adapter, Test and Measurement Controller, Legacy Communication Appliance.
Legacy PCI Network Adapter
The DP83815DUJB fits a legacy PCI network adapter because it integrates a 10/100 Mb/s Media Access Controller, a PCI host interface, and a 10BASE-T/100BASE-TX physical layer in one 160-LBGA device. According to the verified distributor specifications, the controller operates from 3 V to 3.6 V and supports full-duplex operation with IEEE 802.3x flow control. A practical design uses the PCI bus for host transactions and an Ethernet transformer plus RJ-45 interface for the physical link. Because the device is associated with obsolete lifecycle status, it is best suited to repairing or reproducing an established PCI platform rather than starting a new commercial platform.
Empfohlen
Industrial Control Ethernet
DP83815DUJB can support copper Ethernet connectivity in legacy industrial controllers that retain a PCI host bus. Its integrated 10/100 Mb/s PHY avoids a separate physical-layer IC, while VLAN support and long-frame support can help organize industrial traffic on compatible managed networks. The verified operating range of 0 °C to +70 °C is suitable for many commercial-temperature enclosures but does not establish suitability for extended industrial temperatures. Thermal and regulatory limits must be checked in the finished equipment. The 160-LBGA footprint also requires a multilayer PCB with short, impedance-controlled Ethernet escapes and dense supply decoupling.
Empfohlen
Embedded Data Acquisition System
The DP83815DUJB is applicable to a PCI-based data-acquisition system needing a dedicated 10/100 Mb/s Ethernet link for transferring measurement data to a host or server. Its integrated MAC and PHY reduce the external interface-component count, and the 100 Mb/s rate is sufficient for many instrument-control and moderate-volume data flows. VLAN and long-frame support can assist traffic segmentation and protocol handling where the host driver and network infrastructure support them. The design must follow the manufacturer’s clock, decoupling, and magnetics requirements, none of which are fully quantified in the supplied snippets.
Empfohlen
Industrial Networking Adapter
DP83815DUJB can be used in a dedicated PCI Ethernet adapter designed to bridge a legacy embedded host to a 10BASE-T or 100BASE-TX network. The integrated PHY supports both speeds, while full-duplex operation and IEEE 802.3x flow control improve link behavior under congestion. Its verified 3 V to 3.6 V operating range and 170 mA supply current provide a starting point for rail design, but production documentation should confirm the detailed current budget. The major procurement concern is lifecycle status: obsolete status requires verified sourcing and careful review of date code, traceability, and long-term maintenance demand.
Empfohlen
Test and Measurement Controller
DP83815DUJB can serve in a test or measurement controller that communicates over a dedicated 10/100 Mb/s Ethernet link. The MAC/PHY integration is useful when the instrument already uses PCI and needs a self-contained network interface. Full-duplex operation supports simultaneous command traffic and measurement-data transfer, while VLAN support can assist segmented laboratory networks. The controller’s 0 °C to +70 °C range is appropriate for many indoor commercial instruments. Layout must isolate the PHY differential pairs from sensitive analog sections and provide the manufacturer-specified clock and power arrangements for stable data transfer.
Empfohlen
Legacy Communication Appliance
DP83815DUJB is suitable for maintaining a legacy communication appliance whose internal PCI bus and 10/100 Mb/s Ethernet connection are already established. The single-chip MAC/PHY approach simplifies repairs compared with systems requiring two major interface ICs, and the device can participate in VLAN-aware enterprise or laboratory networks. The principal limitation is availability rather than functional capability: the verified cross-reference material describes the device as obsolete. Procurement should therefore prioritize traceable original stock, while firmware and operating-system support must be confirmed separately because those details are absent from the supplied data.

Wichtigste Unterscheidungsmerkmale

- Documented commercial temperature range (vs. DP83815A)
Designhinweise
Plan the 160-LBGA escape routing before schematic sign-off. The package has no perimeter leads, so every power, ground, PCI, clock, and PHY signal may require vias into or beneath the device footprint. Reserve via-in-pad or via-adjacent escape options, verify the manufacturer’s land pattern, and maintain short current paths to decoupling capacitors. Do not derive the footprint from a generic 160-ball library without checking ball pitch, exposed-pad treatment, and thermal-via requirements against the official package drawing.
Route the Ethernet differential pairs as a controlled-impedance pair over a continuous reference plane, avoid stubs and right-angle transitions, and keep the pairs away from clocks, switching nodes, and noisy return paths. Place the PHY-side passive network and magnetic-device connection in accordance with the manufacturer reference circuit. The supplied results confirm 10BASE-T and 100BASE-TX support but do not provide trace-impedance, insertion-loss, or magnetics-selection data, so those values must be taken directly from the manufacturer documentation.
Build the 3.3 V rail within the verified 3 V to 3.6 V operating range and reserve margin for tolerance and transients. The reported 170 mA supply current is a useful starting point, but it is not a complete rail-current budget. Separate high-frequency bypass placement from bulk capacitance, provide a low-impedance return path, and verify sequencing requirements in the manufacturer datasheet. Because the available lifecycle data identifies this device as obsolete, stock longevity and traceability should also influence power-design and maintenance planning.
Do not treat the DP83822IRHBR result as a drop-in replacement: the verified cross-reference result identifies a different package, and a package change requires PCB redesign. Likewise, the suggestion that DP83815 or DP83815A may be alternatives does not establish a complete pin match. Before procurement, compare ordering tables, ball maps, supply requirements, clock connections, transceiver pins, exposed-pad connections, and reset behavior against the official documentation for the installed DP83815DUJB.
Compliance-Informationen
The supplied verified results do not state RoHS, REACH, lead-free, halogen-free, conflict-minerals, or AEC-Q100 status. AEC-Q100 is marked not applicable because this commercial Ethernet controller is not identified as an automotive-qualified product; confirm other declarations against the manufacturer product page or packaging documentation.
