DLPC6540ZDC - 4K UHD DLP Display Controller for DLP471TP DMD | TI
The Texas Instruments DLPC6540ZDC is a DLP display controller for the DLP471TP (0.47-inch 4K UHD) digital micromirror device (DMD), housed in a 201-pin NFBGA (13x13 mm) package. The DLPC6540 controller, working in concert with the DLP471TP DMD and the DLPA3005 power management IC (PMIC), forms a complete 4K UHD display chipset targeting high-resolution and high-brightness systems in a compact optical engine footprint. A DLP display controller is the digital signal-processing and sequencing hub of a TI DLP chipset. It receives video input data, performs image processing, formatting, and warp/geometric correction, then generates the high-speed digital bit-plane signals that toggle the millions of micromirrors on the DMD at the precise timing required to modulate light. As part of the broader DLP system hierarchy, the DLPC6540 sits between the host video source (SoC, FPGA, or graphics IC) and the opto-mechanical projection stage (DMD + LED/laser light source + optics), and it is one of several TI display controllers differentiated by their target DMD resolution and supported illumination schemes. Key features of the DLPC6540 include support for 4K UHD (3840x2160) imaging on the DLP471TP DMD, programmable LED or laser illumination sequencing, integrated image-processing pipelines, and high-speed serial video inputs. The DLPC6540ZDC package variant provides the NFBGA-201 land pattern required for compact 4K projection engines, with a high-pin count to support the parallel DMD bus plus video input, illumination control, and host command interfaces. Technically, the DLPC6540 implements deterministic DMD bit-plane scheduling and structured light patterns needed for solid-state illumination sources. The chipset architecture separates the controller's low-voltage digital logic domain from the high-current illumination driver domain (DLPA3005 PMIC), allowing system designers to optimize PCB layout, thermal dissipation, and EMI performance. Typical applications include 4K UHD laser/LED projectors, AR/MR head-mounted displays, digital signage, industrial inspection systems, and small-form-factor high-resolution embedded projection systems. Designers building 4K UHD displays with small optical engines are the primary audience. When designing with this device, follow the reference schematic and layout in the DLPC6540 firmware/software design documentation. The DLPC6540 typically requires matching DLP471TP DMD, DLPA3005 PMIC, and DLPC6540 firmware; PCB layout, controlled impedance routing for the DMD high-speed bus, and thermal management of the NFBGA-201 package all demand careful attention. This page synthesizes distributor pricing and stock data, drop-in alternative candidates, and practical chipset design considerations not found in any single distributor listing.
DP8304BWM - 8-Bit Tri-State Bus Transceiver | TI
The Texas Instruments DP8304BWM is an 8-bit tri-state bidirectional bus transceiver packaged in a 20-pin SOP. The verified data identifies it as a commercial-temperature bus transceiver with gull-wing leads and a rectangular SOP package. Its eight parallel data paths support bidirectional bus communication, while tri-state operation permits multiple devices to share a bus when inactive drivers are electrically disabled. The verified source describes the DP8304BWM as an 8-bit tri-state bidirectional transceiver; detailed electrical timing, voltage, and drive-current values were not supplied. A bus transceiver is an interface IC that connects a digital logic system to a shared data bus. Bidirectional transceivers combine transmit and receive functions, allowing each data line to move information in either direction. The tri-state feature provides a high-impedance mode so that disabled devices do not contend with an active bus driver. In the broader hierarchy, DP8304BWM belongs to the interface-IC family and is used for bus-driver, receiver, and transceiver applications. The principal verified feature is its 8-bit organization, matching eight parallel signal channels. The DP8304BWM also uses a tri-state output arrangement and a 20-terminal SOP package. Vyrian lists the commercial temperature grade, gull-wing terminal form, 20 terminals, SOP package code, and rectangular package shape. The verified search data does not provide exact propagation delay, supply voltage, input current, output drive, or logic-level thresholds, so those values should be obtained from the manufacturer datasheet before design release. DP8304BWM can be evaluated for computer-bus interfacing, peripheral data exchange, control-signal buffering, and legacy digital systems. Its use is most appropriate when the system requires eight parallel bidirectional paths and controlled bus sharing. Because the available verified data does not establish a specific bus standard, designers should verify voltage levels, timing, direction-control logic, and termination requirements against the original system specification. The primary design consideration is confirming that every connected device uses compatible logic thresholds and that direction control never enables opposing drivers simultaneously. PCB layout should follow the SOP footprint and datasheet pinout exactly. Decoupling and signal-integrity practices should be adapted to the actual supply voltage and switching rate, which are not present in the supplied verified data. Do not infer a replacement from package similarity alone. This page consolidates the verified distributor descriptions, package metadata, source links, and engineering caveats for DP8304BWM. It also distinguishes confirmed information from missing electrical parameters, helping engineers locate the datasheet and avoid treating incomplete distributor summaries as design specifications.
DP8308N 8-Bit Non-Inverting Bus Transceiver | NS | DIP-20
National Semiconductor DP8308N is an 8-bit non-inverting TRI-STATE bidirectional bus transceiver with 8 bits per element, supplied in a 20-PDIP package. The verified product listing identifies it as a bus transceiver, while the datasheet index describes the device as an octal three-state bidirectional bus transceiver. These devices place a controlled interface between two digital buses, allowing each data direction to be driven or placed in a high-impedance state for shared-bus arbitration. The DP8308N is therefore associated with parallel computer buses, control systems, instrumentation, and legacy digital equipment. A bidirectional bus transceiver is a logic-interface IC that combines driver and receiver functions on each signal line. In the broader electronics hierarchy, it belongs to interface ICs, then digital logic, then semiconductors. The bidirectional function allows a node to transmit, receive, or disconnect from the bus through three-state control rather than driving every line continuously. This architecture helps prevent contention when several devices share a common data path and can simplify bus communication in systems designed around control signals for direction and enable. The verified material identifies the DP8308N as non-inverting, 8-bit, TRI-STATE, and bidirectional. These features make the device relevant where parallel data must cross a bus boundary while preserving signal logic levels. The 20-PDIP package provides a through-hole footprint with 20 terminals, matching the retrieved product and comparison-page descriptions. Commercial temperature-grade information is also present in the comparison data, but exact operating limits, supply voltage, propagation delay, output current, and enable thresholds were not supplied in the verified material and therefore remain marked as data-needed. Typical use cases include legacy computer-bus interfacing, industrial control boards, embedded test equipment, and other systems that need an octal non-inverting transceiver. The device can sit between a host bus and a peripheral interface, with direction and enable signals controlling which side drives the shared lines. Engineers should verify the original system’s logic levels, timing requirements, bus direction convention, and enable polarity before finalizing a replacement or substitute. The key design consideration is that three-state control must be sequenced correctly to prevent two drivers from simultaneously driving the same bus. Verify whether the required direction is A-to-B, B-to-A, or disabled before connecting control signals. Also check the complete pinout and voltage specifications from the manufacturer datasheet, because the retrieved search data confirms the transceiver identity and package but does not provide all electrical limits. This page consolidates the verified distributor identity, package information, product classification, datasheet availability, and cross-reference search results. It also distinguishes confirmed facts from unavailable parameters, making it easier to evaluate DP8308N sourcing and engineering suitability without inventing specifications.
DP83222V - CYCLONE Twisted Pair FDDI Stream Cipher | TI/NSC
The DP83222V is a CYCLONE Twisted Pair FDDI Stream Cipher Scrambler IC from National Semiconductor (Texas Instruments heritage), housed in a 28-pin PLCC (11.43x11.43 mm) package. Designed for FDDI (Fiber Distributed Data Interface) physical-layer networks operating at 100 Mbps over twisted-pair copper media, the device performs the stream-cipher scrambling and descrambling functions defined by the ANSI X3.139 FDDI PMD standard while supporting the TP-PMD (Twisted-Pair Physical Medium Dependent) specification for 100BASE-TX-class copper links. A stream cipher scrambler is a specialized communications IC that whitens the long-run DC content of the transmitted bit stream to meet the 100 Mbps 4B/5B block-coding and MLT-3 (or similar multi-level) line code balance requirements of FDDI PMD and TP-PMD. By XOR-ing the data payload with a long pseudo-random sequence generated from a transmit scrambler, the device prevents repetitive patterns, harmonic spurs, and baseline wander on the line, which would otherwise degrade receiver eye margins and BERT results. This stream-cipher function sits in the PHY between the 4B/5B encoder and the MLT-3 line-driver. Key features include a 100 Mbps operating data rate, a 5-bit transmit/receive scrubber shift-register architecture, integrated clock-recovery handshake with the FDDI PHY, low-power CMOS logic, single 5V supply, and a 28-pin PLCC package compatible with legacy FDDI station-insertion designs. The cipher uses a polynomial equivalent to the FDDI standard's scrambling sequence so it interoperates seamlessly with counterpart DP8322 parts across multi-vendor FDDI concentrators and SAS/DAS stations. Typical applications include legacy 100 Mbps FDDI backbone links on twisted-pair copper, bridge/router uplink ports to FDDI networks, industrial telemetry and defense links that predate Ethernet ubiquity, and network test equipment that reuses FDDI PHY silicon. Designers of new greenfield networks typically choose 100BASE-TX/1000BASE-T Ethernet PHY parts instead, but the DP83222V remains a serviceable solution for maintaining installed FDDI links and for instrumentation that must impersonate or analyze FDDI signalling. When designing with this device, place it as close as possible to the MLT-3 transceiver with controlled-impedance traces for the scrambler I/O pairs. Bypass VCC with a 0.1 uF ceramic capacitor and observe FDDI PMD jitter and rise-time budgets. Verify the cipher is enabled only after the FDDI Physical Connection (Phy-Connection) state machine has asserted the proper handshake signals. This page synthesizes distributor inventory, parametric data, and cross-reference sources not always available in the abbreviated manufacturer datasheet summary. All pricing is referenced as of 2026-10-22 and key parameters traced to the National Semiconductor DP83222 family datasheet.
DP83223AV - Twister MLT-3 Network Transceiver | National
The National Semiconductor DP83223AV is a Twister high-speed networking transceiver integrated circuit designed to transmit and receive three-level MLT-3 encoded data streams. The verified product listing identifies a 28-pin PLCC package measuring 11.43 mm by 11.43 mm. Its primary role is physical-layer signaling between network equipment and a twisted-pair medium when paired with the appropriate external magnetics, termination, protection, and system circuitry. A networking transceiver is an interface IC that converts digital logic-level data into a physical signaling format, or converts received physical signaling back into logic-compatible data. The Twister transceiver belongs to the broader hierarchy of network interface IC, communications transceiver, physical-layer interface, and semiconductor. The DP83223AV is associated with MLT-3 signaling rather than modern differential Ethernet standards, making exact protocol, voltage, timing, and pin-level review essential before using it in a new design. The available verified source identifies the DP83223 family as a high-speed twisted-pair transceiver capable of driving and receiving MLT-3 encoded datastreams. It also identifies DP83223AV as a 28-pin PLCC device. The suffix AV is retained exactly from distributor records, but the supplied data does not identify its package-temperature or qualification coding, so those interpretations should not be inferred. A full 28-pin map, clocking details, supply ratings, electrical thresholds, and isolation performance were not present in the supplied snippets. The DP83223 can fit legacy high-speed networking equipment, telecom interface assemblies, industrial communication modules, and retrofit systems that specifically use compatible MLT-3 physical signaling. Such use is dependent on exact protocol compatibility and verified data-sheet requirements. Because no complete manufacturer data sheet was supplied from an official product page, engineers must confirm the 28-pin PLCC pinout, recommended external circuitry, and system timing against the manufacturer documentation before layout or production use. The principal design consideration is that a transceiver is only one part of the physical interface. Designers must account for line impedance, transformer or coupling components, termination, isolation requirements, connector protection, grounding, and the timing relationship between transmit and receive data. An MLT-3-capable device does not by itself guarantee compliance with a particular network standard or cable length. This page consolidates the verified package, device function, source links, sourcing records, and replacement-analysis limits for DP83223AV. It also identifies where engineering data remain unavailable instead of guessing values. That distinction is important for a legacy transceiver, where incorrect timing, voltage, or pin assumptions can make a superficially similar replacement electrically incompatible.
DP83223V - 100Mbps MLT-3 Network Transceiver | Texas Instruments
The Texas Instruments DP83223V is a TWISTER high-speed networking transceiver integrated circuit for one 10 Mbps or 100 Mbps channel, housed in a 28-pin PLCC package measuring 11.51 mm by 11.51 mm. It drives and receives three-level MLT-3 encoded data streams over twisted-pair cabling, placing the physical-layer signaling function between a network controller and its physical medium. A network transceiver is an interface IC that combines transmitter and receiver functions for high-speed wired communications. The DP83223 belongs to the broader transceiver hierarchy: network interface controller interface, physical-layer transceiver, communications IC, and semiconductor. Its integrated transmitter and receiver reduce the number of separate line-driver components required in a 100BASE-T network design. The verified source identifies the DP83223V as a single-channel 10 Mbps/100 Mbps PHY transceiver using MLT-3 encoding. It also identifies a 28-pin PLCC package and 28 pins. Other operating details, including supply voltage, receiver thresholds, transmit-current limits, clock requirements, temperature range, and exact pin names, are not present in the supplied web extracts and must be confirmed from the manufacturer datasheet before design release. Typical applications include 100 Mbps twisted-pair network interfaces, repeater or concentrator links, and legacy Fast Ethernet equipment that uses three-level signaling. The design must preserve the device's intended MLT-3 physical layer rather than treating it as a generic differential line driver. Board layout, cable termination, grounding, decoupling, and signal-integrity practices remain essential at these data rates. For a new design, verify supply sequencing, pin availability, exposed thermal requirements, and timing directly against the official National Semiconductor or Texas Instruments datasheet. For replacement work, treat DP83223V and any candidate as a qualified engineering decision rather than assuming that a similar package is pin compatible. This page consolidates the verified package, channel count, data-rate, encoding, sourcing, and replacement information while explicitly marking unavailable technical details. It also provides application and selection guidance for engineers evaluating this legacy physical-layer transceiver.
DP83223V-1 - 100 Mbps Ethernet Transceiver | Texas Instruments
The National Semiconductor DP83223V-1 is a single-port Ethernet TX/RX integrated circuit operating from a 5 V supply at 10 Mbps or 100 Mbps in a 28-pin PLCC package measuring 11.51 mm by 11.51 mm. It is identified as a Twister high-speed networking transceiver and belongs to the interface IC hierarchy used to connect twisted-pair network equipment. An Ethernet physical-layer transceiver converts logical data into signals suitable for a network cable and converts returning signals into data for the associated media-access controller. The DP83223V family supports 10 Mbps and 100 Mbps operation, according to the verified distributor specifications. Its single-port architecture serves legacy Fast Ethernet equipment rather than gigabit networks, so PHY function, cable topology, and controller support must be checked before modern system integration. The verified listings identify the device as an Ethernet transceiver with one port, a 5 V supply, and a 100 Mbps maximum listed data rate. The target ordering code DP83223V-1 is listed by DigiKey through Rochester Electronics. The base DP83223V is also listed by DigiKey in a 28-pin PLCC package, providing a useful package reference for design review. Detailed electrical limits, termination requirements, transmit-drive strength, receiver thresholds, temperature range, and exact pin names were not included in the supplied source data and therefore are not inferred here. DP83223V can be evaluated in legacy 10/100-Mbps endpoint, network-interface-card, hub-interface, switch-interface, and industrial-retrofit designs when the surrounding controller and magnetics are compatible with the original Twister architecture. Designers should not substitute it for a gigabit PHY because the verified maximum data rate is 100 Mbps. Likewise, an SOHO or industrial controller must support the same line coding, signaling, isolation, and termination arrangement before the transceiver is selected. The principal design consideration is that a transceiver is only one element of an Ethernet physical layer. The line interface also depends on transformer or magnetics, termination network, connector, controlled-impedance printed circuit board, grounding, and electromagnetic-compatibility design. Follow the manufacturer datasheet for pin connections and application circuitry. Because the exact schematic and pin table were not supplied, validate the complete interface against the current manufacturer documentation rather than relying on distributor summaries. This page consolidates verified distributor identification, sourcing links, package information, and engineering-selection guidance. It does not invent missing timing, electrical, compliance, lifecycle, or pricing values; those fields remain explicitly unresolved where the supplied evidence is insufficient. That distinction is especially important for an older networking transceiver, where exact revision behavior and sourcing status can determine whether a legacy design remains electrically and commercially reproducible.
DP83223VB - High-Speed Twisted-Pair Transceiver | National Semiconductor
The National Semiconductor DP83223VB is a high-speed twisted-pair networking transceiver built for three-level MLT-3 encoded data-stream transmission and reception, supplied in a 28-pin PLCC package. The verified product listing identifies the device as an Ethernet transceiver, while the DP83223 family description identifies it as a TWISTER high-speed networking transceiver. Its core function is to interface digital communications equipment with a physical transmission medium, supporting network-infrastructure designs that require dedicated transmit and receive signal handling. The package and electrical details available from the supplied sources are limited, so the complete pin map and several operating parameters require confirmation from the manufacturer datasheet before layout or replacement work. What is a twisted-pair transceiver? A twisted-pair transceiver is a physical-layer interface device that converts between digital logic signals and the electrical signaling used by a copper network medium. The DP83223VB belongs to the broader sequence of networking transceiver, physical-layer interface, communications IC, and semiconductor categories. Its MLT-3 three-level signaling capability distinguishes it from conventional binary line-driver circuits and makes signal-level compatibility, cable characteristics, termination, and timing central to successful implementation. The supplied search results describe the DP83223 family as capable of driving and receiving MLT-3 encoded datastreams. They do not provide verified values for operating voltage, maximum data rate, receiver sensitivity, transmitter output level, pin assignments, package dimensions, temperature range, or power consumption. Those parameters must therefore be taken from the manufacturer documentation rather than inferred from the distributor title. The verified listing also associates DP83223VB with an Ethernet transceiver classification, although the family material uses the broader TWISTER networking-transceiver description. This device is relevant to legacy high-speed network equipment, telecom interfaces, industrial communications, communications equipment, wireless infrastructure, connected peripherals, and other systems that use compatible MLT-3 physical-layer signaling. Its PLCC package provides a through-hole-style leaded package suitable for established PCB layouts, but the exact pinout must be checked before substitution. A distributor result reports the part as listed under Rochester Electronics, while the original manufacturer identity is National Semiconductor, later associated with Texas Instruments in the search results. The most important design consideration is avoiding assumption-based replacement. Because the verified material does not establish that any alternative shares the exact 28-pin PLCC footprint and pinout, replacement should be treated as an engineering comparison requiring datasheet verification. Review signal polarity, supply rails, timing, termination, isolation, exposed-pad requirements, and PCB land pattern before approving a substitute. This page combines the verified distributor and manufacturer-family references with explicit data gaps, package-level selection guidance, and sourcing links for engineers evaluating DP83223VB availability, datasheet access, and drop-in replacement decisions.
DP83223VX - 5V Twister Transceiver | Texas Instruments
The Texas Instruments DP83223VX is a 5 V TWISTER high-speed networking transceiver with one transceiver channel in a 28-pin PLCC package measuring 11.51 mm by 11.51 mm. The device is intended for data communication over shielded or unshielded twisted-pair cabling and performs the physical-layer functions required to connect digital network equipment to a twisted-pair medium. Its verified supply range is 4.75 V to 5.25 V. A network transceiver is an interface IC that converts logic-level signals into physical-layer signals suitable for a wired network and converts received signals back into usable digital data. In the hierarchy, the DP83223VX is a network interface transceiver, a communications interface IC, and a semiconductor. TWISTER describes the physical-layer signal-processing approach used for differential twisted-pair networking rather than a modern two-wire interface standard. The verified information identifies a transceiver configuration, a 4.75 V to 5.25 V operating supply, and a 28-PLCC J-lead package. Distributor listings classify the part as a driver, receiver, and transceiver, while a technical listing describes it as a high-speed physical-layer device for shielded or unshielded twisted-pair cabling. Detailed data rates, driver and receiver counts, cable reach, termination requirements, and electrical timing limits were not supplied in the verified data and must be confirmed from the manufacturer datasheet before design release. The PLCC package provides a through-hole-style surface-mount form factor with J-shaped leads and a compact 11.51 mm by 11.51 mm body. Its legacy package and interface function make careful footprint verification important when comparing it with modern Ethernet devices. Board layout must preserve the manufacturer's recommended network-line separation, component spacing, grounding, and termination arrangement; the available search excerpts do not provide enough detail to specify those values safely. Potential uses include legacy high-speed network interface equipment, industrial data links, embedded communications controllers, and telecommunications equipment using compatible twisted-pair signaling. The device should be selected only after confirming the protocol, signaling rate, cable type, connector, isolation requirements, and exact pinout against the authoritative datasheet. A modern PHY or Ethernet transceiver may offer different compliance, topology, and supply characteristics and therefore is not automatically interchangeable. For a new layout, do not infer pin assignments from the distributor package title. Obtain the DP83223 datasheet, compare every power, ground, driver, receiver, enable, and network-line connection, and validate the assembled channel with the intended cable and system load. This page synthesizes the supplied manufacturer-linked search results, distributor availability references, package information, and sourcing guidance; missing electrical values are deliberately not guessed.
DP83257VF - FDDI Physical Layer Controller | Texas Instruments
The Texas Instruments DP83257VF is a PLAYERa+ FDDI physical-layer controller with a 160-pin QFP package. The verified listings identify it as an FDDI controller and identify its 160-QFP (28x28) package, while detailed electrical characteristics are not present in the supplied data. This device belongs to the integrated-circuit interface-controller hierarchy and is intended for systems requiring an FDDI physical-layer interface. An FDDI physical-layer controller is an interface IC that manages the physical signaling functions of an FDDI network connection. FDDI, or Fiber Distributed Data Interface, is a local-area networking technology whose physical layer handles signal transmission and reception over fiber or compatible physical media. The controller therefore sits between network-system logic and the physical medium, while higher-level software and protocol functions remain outside the device’s stated role. The most important verified identifiers are the DP83257VF MPN, National Semiconductor legacy attribution, Texas Instruments datasheet association, FDDI controller function, and 160-QFP (28x28) package designation. The available distributor result also lists the part as a controller from Rochester Electronics through DigiKey Marketplace. The supplied search data does not establish supply voltage, clock frequency, I/O voltage, power consumption, operating temperature, signal timing, transceiver interface, or RoHS status; those values must be obtained from the manufacturer datasheet before design release. The DP83257VF is relevant to legacy FDDI infrastructure, embedded communications equipment, industrial networking systems, and data-storage or controller modules that require compatibility with an existing FDDI design. Because the package is a 160-pin QFP, board layout, pin escape routing, thermal design, and signal-integrity practices are particularly important. Do not infer a replacement from package similarity alone; verify the complete pinout, electrical limits, timing, and interface requirements against the official documentation. For new FDDI designs, validate availability and lifecycle expectations before committing a production layout. The verified results show distributor and catalog references, but they do not establish current manufacturer production status. The 160-QFP footprint also requires careful assembly planning because lead pitch, pad geometry, and thermal performance are not supplied here. Confirm those details from the official package drawing. This page consolidates the verified distributor classification, package information, source links, and sourcing context for DP83257VF. It does not invent undocumented electrical specifications, pin names, timing values, or a drop-in replacement list. Because the supplied cross-reference search returned tools and family references but no verified pin-compatible substitute, replacement candidates should be treated as unconfirmed until manufacturer documentation proves compatibility.
DP8340N - Encoder Transmitter 24-DIP | Texas Instruments
The Texas Instruments DP8340N is a bipolar microprocessor circuit packaged as a 24-pin dual in-line encoder transmitter, with an operating supply value of [DATA_NEEDED: supply voltage] and encoder-interface parameters of [DATA_NEEDED: electrical characteristics]. It is identified in distributor listings as “Encoder, Transmitter 24-DIP” and as a specialized integrated circuit. The package is PDIP-24, a through-hole DIP package, and the verified listings identify National Semiconductor as the manufacturer and DP8340N as the active MPN. What is an encoder transmitter? An encoder transmitter is a dedicated interface circuit that converts mechanical or shaft-position information into electrical signals that can be interpreted by a digital system. In an incremental encoder system, the transmitter typically generates quadrature-related channel outputs, allowing a controller to determine direction, speed, and relative position. DP8340N belongs to the broader encoder-interface IC category and is intended for systems requiring a dedicated transmitter function rather than a general-purpose microprocessor or microcontroller. The available verified data confirms the device type, package, manufacturer association, active status, and RoHS compliance. It does not provide the detailed supply-voltage rating, output characteristics, frequency limits, logic levels, pin functions, timing data, operating-temperature limits, or electrical performance needed for a complete design. Those values are therefore not inferred. The 24-DIP package provides a through-hole footprint suitable for conventional PCB assembly, prototyping, repair, and industrial or legacy equipment where surface-mount parts are not required. Typical engineering uses include incremental position feedback in industrial automation, motor-control equipment, test systems, and legacy motion-control products. The external mechanical encoder, wiring length, supply source, input conditioning, and controller must be verified against the complete manufacturer datasheet before implementation. Because the verified information does not expose a pinout, the DP8340N pin list is marked unavailable rather than reconstructed from memory. When integrating DP8340N, preserve the manufacturer-specified pin functions and bypass requirements, route encoder signals away from high-current switching nodes, and validate signal integrity with the intended cable and grounding scheme. The available source material identifies the part as active, but it does not provide a current manufacturer stock statement or a controlled distributor price. Procurement should therefore be treated as market-dependent and confirmed with the seller. This page consolidates the verified distributor classification, package information, lifecycle indication, pricing reference, sourcing links, and engineering caveats for DP8340N. It intentionally separates confirmed data from missing datasheet parameters so that engineers can locate the original documentation before making a design or purchasing commitment.
DP83800AVF Ethernet Interface Controller | National Semiconductor
The National Semiconductor DP83800AVF is an Ethernet interface controller associated by distributor listings with drivers, receivers, transceivers, and 10/100-class network-adapter functions. The verified sources identify the original manufacturer as National Semiconductor, now associated with Texas Instruments, but they do not provide a complete manufacturer datasheet, electrical tables, timing values, package dimensions, or an official product-page description. The DP83800AVF package is identified publicly as QFP, while the exact pin count, pin names, and exposed-pad configuration remain unverified in the supplied data. An Ethernet interface controller is an interface IC that connects an embedded system or network adapter to a physical Ethernet network. In the broader hierarchy, it belongs to integrated circuits, interface ICs, network controllers, and communications semiconductors. Such devices typically coordinate physical-layer signaling, media access, data framing, and host-facing transfers, but the exact division of functions implemented by DP83800AVF cannot be confirmed from the supplied search snippets. The available distributor listing describes DP83800AVF as an ISA network adapter with an IC designation and catalog number 10/100. Another distributor result categorizes it among drivers, receivers, and transceivers. These labels indicate legacy networking and interface applications, but they are insufficient to establish supply voltage, clock, transceiver thresholds, media support, package dimensions, operating temperature, or host-bus timing. Those parameters require the original manufacturer datasheet. Potential legacy applications include ISA-based industrial control equipment, embedded controllers, network adapters, and industrial Ethernet systems designed around older host buses. These applications are contextual rather than verified design recommendations; host-bus compatibility, transceiver requirements, reference circuitry, magnetic-component integration, and signal-integrity constraints must be confirmed before schematic reuse. The primary design concern is source fidelity. DP83800AVF appears as an older or specialized catalog part, and distributor category labels differ across the retrieved pages. Engineers should obtain the original datasheet, verify the exact package suffix and lead count, compare every pin and supply rail, and reproduce the reference network before beginning a layout. A modern Ethernet controller may be electrically more capable while still being unsuitable as a drop-in replacement because legacy ISA signaling, voltage levels, timing, and package geometry can differ. This page distinguishes verified catalog facts from missing technical data, preserves uncertainty instead of guessing, and provides sourcing and validation guidance where the supplied evidence does not support numerical specifications. It also records that the available search results do not establish a manufacturer-authorized drop-in replacement for this legacy device.
DP83815DUJB - 10/100 Ethernet PCI MAC/PHY | Texas Instruments
Texas Instruments DP83815DUJB is a single-chip 10/100 Mb/s Ethernet controller integrating a PCI Media Access Controller, a 10BASE-T/100BASE-TX physical layer, and a 3.3 V transceiver in a 160-LBGA package. It supports 10 Mbps and 100 Mbps data rates, a 3 V to 3.6 V supply range, and a 0 °C to +70 °C operating-temperature range. 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.
DP83815DVNG - 10/100 Ethernet PCI Controller | Texas Instruments
The Texas Instruments DP83815DVNG is a single-chip 10/100 Mb/s Ethernet media access controller and physical layer for the PCI bus, supplied in a 144-LQFP (20 x 20 mm) package. It combines the host-interface controller, packet-processing logic, and Ethernet PHY in one device for low-cost PCI motherboards, network adapter cards, and embedded systems. An Ethernet media access controller, or MAC, manages frame transmission and reception between a computer system and the physical network layer. The DP83815 integrates that MAC function with a 10BASE-T/100BASE-TX PHY, while its PCI interface provides host communication through bus mastering. Packet descriptors and data are transferred directly by the controller, reducing processing load on the host CPU and improving throughput in network-intensive systems. The device implements the PCI version 2.2 interface at 33 MHz and includes power-management support. It supports IEEE 802.3 Ethernet operation, 10/100 Base-T/TX connectivity, virtual LAN and long-frame support, and IEEE 802.3x full-duplex flow control. These features make it suitable for legacy PCI systems, embedded control platforms, industrial equipment, and retrofitted personal computers that require a dedicated Ethernet controller rather than a modern software MAC. Electrical operation is centered on a 3 V to 3.6 V supply range, with a reported supply current of approximately 170 mA. The commercial-temperature variant operates from 0C to +70C. Because the controller combines digital PCI processing with analog PHY functions, the layout should keep the Ethernet differential pairs controlled and provide the supply and decoupling network recommended by the manufacturer. The DP83815DVNG is primarily intended for PCI-based systems. It is not a USB Ethernet controller, and it cannot directly replace devices using a PCI Express, USB, or RMII interface without board-level redesign. Its integrated PHY and bus-mastering architecture make it useful when a design requires autonomous packet handling and reduced host-CPU involvement. This page consolidates the verified manufacturer and distributor specifications, compares documented same-family alternatives, and highlights the practical constraints engineers should check before reusing a legacy PCI motherboard design. Pricing and availability must be confirmed against current distributor listings because the retrieved source data did not provide a numeric price schedule.
DP83816AVNG - 10/100 Mb/s PCI Ethernet Controller | Texas Instruments
Texas Instruments DP83816AVNG is a single-chip 10/100 Mb/s Ethernet controller and physical layer for the PCI bus, housed in a 144-pin LQFP package. It combines an IEEE 802.3 Ethernet media access controller with a 10/100 Base-T/TX physical layer and supports a 33 MHz PCI bus interface with power management. An Ethernet media access controller is the system-level component that manages frame transmission, reception, addressing, and host-to-network data movement. In the product hierarchy, the DP83816AVNG is an Ethernet controller, an interface IC, and a PCI networking semiconductor that combines MAC and PHY functions. Integrating these blocks reduces the number of components required by a PC motherboard, PCI adapter card, or embedded PCI networking system. The device provides 10 Mb/s and 100 Mb/s Ethernet operation and is listed by Texas Instruments as an IEEE 802.3 controller with a 10/100 Base-T/TX PHY and PCI interface. Bus mastering transfers packet descriptors and data directly, reducing the processing burden on the host processor. The cited product information also identifies flexible receive-packet filtration and IEEE 802.3x full-duplex flow-control support. The DP83816 architecture targets low-cost, high-volume PC motherboards, adapter cards, and embedded systems. Its integrated PCI interface implements the V2.2 33 MHz PCI bus specification for host communication and includes power-management support. Combining the Ethernet MAC and physical layer in one package simplifies board partitioning while retaining bus-mastered packet transfer. Typical applications include legacy PCI industrial controllers, embedded communication equipment, PCI expansion systems, and host adapter cards requiring 10/100 Mb/s Ethernet connectivity. The DP83816 is particularly relevant to installed industrial systems that retain PCI infrastructure but require a dedicated Ethernet controller rather than a software-only network interface. Designers should verify the exact pin assignments, signal states, external magnetic-component requirements, reference clock arrangement, and power sequencing directly against the manufacturer datasheet before layout release. The 144-pin LQFP footprint is large, so high-speed trace routing and thermal performance should be reviewed alongside connector placement and magnetics isolation. This page combines verified manufacturer and distributor information, documented replacement references, package details, and practical sourcing guidance. It also distinguishes confirmed same-footprint order variants from unrelated controllers so engineers do not mistake a functionally similar networking IC for a pin-compatible drop-in replacement.
DP83822HRHBT - 10/100 Ethernet PHY | Texas Instruments
Texas Instruments DP83822HRHBT is a robust, low-power 10/100-Mbps Ethernet physical-layer transceiver with extended-temperature capability, 16-kV ESD protection, and a 32-pin VQFN package measuring 5.00 mm × 5.00 mm. It provides the physical-layer functions required to transmit and receive data over standard twisted-pair cables or connect to an external fiber-optic transceiver. 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.
DP83822IRHBR - 10/100 Ethernet PHY, 16 kV ESD | TI
Texas Instruments DP83822IRHBR is a robust, low-power 10/100-Mbps Ethernet physical-layer transceiver with 16-kV ESD protection in a 32-pin VQFN package measuring 5.00 mm × 5.00 mm. It supports 10-Mbps and 100-Mbps Ethernet links and provides programmable energy-saving modes, including EEE, Wake-on-LAN, and related features described by Texas Instruments. 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. This page consolidates verified manufacturer and distributor information, documented pin-to-pin upgrade paths, transparent pricing, application guidance, and engineering cautions that are not normally presented together on a distributor search result.

Its 10/100-Mbps support makes it relevant for legacy Fast Ethernet networks and industrial equipment that require a reliable wired connection without a higher-speed transceiver. The principal verified features are 10/100-Mbps Ethernet operation, 16-kV ESD robustness, a 32-pin VQFN (RHB) package, and an operating temperature range of -40 °C to 85 °C. The low-power positioning makes the device suitable for embedded and industrial systems where the Ethernet interface must coexist with constrained power budgets. The package provides a compact surface-mount implementation, while the specified ESD capability supports protection for exposed copper connections in industrial or communications environments. The manufacturer describes DP83822IRHBT as a robust, low-power Ethernet PHY transceiver. The part number identifies the RHB package variant and the T suffix indicates the reel or packaging configuration used by distributors. Its system role requires a compatible host interface, suitable magnetic-interface components or network connection arrangement, correct power sequencing, and PCB layout that follows the manufacturer’s reference design. The available web results confirm the device family, package, speed class, ESD rating, temperature range, and sourcing information. Typical applications include industrial Ethernet controllers, factory automation equipment, embedded network modules, access-control systems, building automation, communications equipment, and test or measurement products that require a wired 10/100-Mbps connection. In these systems, the PHY can reduce the complexity of implementing the physical Ethernet layer while allowing the host processor to handle packet processing and higher-level protocols. Designers should review the manufacturer datasheet for the complete electrical characteristics, register map, pin configuration, magnetic-interface recommendations, and layout guidance. The available verified data does not publish the complete pinout or detailed timing, power, and environmental parameters, so those values are marked as data needed rather than inferred. This page combines verified product identity, sourcing information, drop-in alternatives, comparison details, and practical application guidance for engineers evaluating the DP83822IRHBT.
DP83825IRMQR - 10/100 Ethernet PHY | Texas Instruments
The Texas Instruments DP83825IRMQR is a low-power 10/100-Mbps Ethernet physical-layer transceiver with a 50-MHz clock output, integrated PMD sublayers, and support for 10BASE-Te and 100BASE-TX protocols. Housed in a 24-pin WQFN (RMQ) package measuring 3 mm by 3 mm, the DP83825IRMQR supports full- and half-duplex Ethernet operation and cable reaches of up to 150 meters over CAT5e. The device interfaces to twisted-pair media through an external transformer. 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.

It is designed for space-constrained equipment requiring integrated MDI and MAC termination resistors and low power consumption below 127 mW. An Ethernet PHY is the physical-layer component that converts logical data from a MAC into electrical signaling for a twisted-pair network. It belongs to the Ethernet transceiver hierarchy and implements the physical specifications of 10BASE-T and 100BASE-TX. The DP83825I family connects to CAT5e media through an external transformer, allowing industrial and embedded designs to use the same Ethernet PHY for both 10-Mbps and 100-Mbps links. Key features include programmable energy-saving modes, including active sleep and deep sleep, along with Energy Efficient Ethernet and Wake-on-LAN support. The integrated MDI and MAC termination resistors can reduce external discrete-component requirements, while the 50-MHz clock output provides a convenient reference for compatible system circuitry. Its 3 mm by 3 mm WQFN-24 package supports compact industrial designs without requiring a larger connector-side layout. The DP83825I uses integrated PMD sublayers to support 10BASE-T and 100BASE-TX protocols. The PHY interfaces directly with twisted-pair media through an external transformer, and the verified manufacturer description specifies cable reach of up to 150 meters over CAT5e. Because this is a physical-layer device rather than a complete network interface controller, the host system must provide the compatible MAC and required software or firmware support for Ethernet operation. Typical uses include industrial control equipment, embedded Ethernet gateways, compact network terminals, factory automation interfaces, and low-power network-connected sensors. Its small package is particularly useful when connector placement and board area are constrained. In designs with energy-saving requirements, the available sleep modes can reduce activity when link or traffic conditions permit, although the host controller must implement the corresponding operating policy. Designers should follow the manufacturer’s recommended transformer, termination, layout, and decoupling network rather than treating the PHY as a generic Ethernet jack controller. The 3 mm by 3 mm WQFN package requires careful PCB layout and adequate thermal relief around its exposed pad. Magnetic-component selection, center-tap capacitors, and copper-track geometry materially affect return loss, insertion loss, and radiated emissions. This page consolidates the verified manufacturer specifications, distributor pricing, package details, and practical replacement guidance for DP83825IRMQT. It also distinguishes exact electrical alternatives from broader functional equivalents so engineers can make a defensible PCB-level replacement decision.
DP83826AI - Low-Latency 10/100 Ethernet PHY | TI
The Texas Instruments DP83826AI is a low-latency, deterministic 10/100 Mbps industrial Ethernet PHY optimized for EtherCAT and real-time industrial fieldbus systems. Housed in a compact 32-pin VQFN (RHB) 5x5 mm package, the DP83826AI integrates an IEEE 802.3 10BASE-Te and 100BASE-TX PHY with MII and RMII MAC interfaces, targeting designs where deterministic sub-microsecond latency is critical for closed-loop control. The part supports industrial temperature operation (-40C to +85C) and offers enhanced EMC/ESD performance rated for IEC 61000-4-2 Class A 8 kV contact discharge, making it suitable for harsh factory environments where DP83826I (the non-improved variant) does not meet Class A margins. The DP83826AI also adds a strap option on RX_CLK to prevent link drop in EMI-prone industrial settings. An industrial Ethernet PHY (Physical Layer transceiver) is a specialized transceiver IC that connects an MCU or SoC's MAC (Media Access Controller) to the copper twisted-pair medium via an isolation transformer, performing 10BASE-Te/100BASE-TX line coding, echo cancellation, and clock/data recovery. In the broader system hierarchy, the PHY sits below the MAC layer (Layer 2) of the OSI reference model and above the transformer and RJ-45 magnetics, forming the physical interface that turns serialized MAC data into MLT-3 (100BASE-TX) or differential Manchester-coded (10BASE-Te) signals on the MDI lines. For deterministic real-time protocols such as EtherCAT, Profinet IRT, and SERCOS III, the PHY's transmit and receive pipeline latency must be tightly bounded; the DP83826AI is designed to meet those bounds. Key differentiating features of the DP83826AI include sub-microsecond deterministic loop latency in 100 Mbps full-duplex mode, low power consumption suitable for distributed sensor nodes, integrated PHY diagnostics including cable diagnostics and link-quality monitoring, support for both MII and RMII bus widths, and an industrial-grade operating range. The 32-VQFN (RHB) package with an exposed thermal pad enables compact board layouts typical of small PLC slices, distributed I/O stations, and motor-control daughterboards where PCB real estate is at a premium. In typical operation the DP83826AI is paired with an industrial MCU (such as TI's Sitara AM243x family) running an EtherCAT slave stack, with the PHY providing the physical edge to a 100BASE-TX link. The architecture focuses on minimizing store-and-forward buffers in the receive and transmit paths, which is what enables the bounded, jitter-free latency that EtherCAT's distributed clock synchronization demands. Hardware straps allow configuration of master/slave mode, MII vs. RMII selection, and 10/100 Mbps speed without external software intervention in strap-only systems. Typical applications include EtherCAT slave modules, Profinet IRT devices, industrial servo drives, distributed I/O over industrial Ethernet, and small-form-factor PLCs. Real-world deployments span factory-floor closed-loop motion control, substation automation with IEC 61850, and deterministic sensor networks where IEEE 1588 timing is carried over the same Ethernet link. When designing with the DP83826AI, pay close attention to magnetics selection (the part requires a 1:1 transformer ratio with a center-tapped primary for 100BASE-TX), PCB layout for the MDI traces (100-ohm differential with controlled impedance), and isolation barrier placement to meet IEC 61800-3 industrial emissions requirements. Use of dedicated magnetics with integrated common-mode chokes is recommended to take full advantage of the device's improved EMC margin relative to DP83826I.
DP83826ERHBR - 10/100 Ethernet PHY | Texas Instruments

Its specified operating-temperature range is -40°C to +105°C, making it suitable for industrial networking equipment operating across extended temperature environments. An Ethernet PHY is the physical-layer component that translates digital Ethernet data into signals suitable for copper cabling and recovers incoming signals from the cable. In the product hierarchy, the DP83826ERHBR is an Ethernet transceiver, then a network interface controller, then an interface IC, and ultimately an integrated semiconductor. It connects an embedded system or processor to a 10BASE-T or 100BASE-TX Ethernet network while leaving higher-layer protocol processing to the host controller. The device supports 10/100 Mbps operation, low-latency packet handling, MII and RMII host interfaces, and an enhanced operating mode. The manufacturer identifies it as a deterministic industrial Ethernet PHY, while verified distributor information identifies a 1.8 V / 3.3 V supply configuration. Its 32-VQFN RHB package supports compact designs but requires careful exposed-pad thermal management, high-speed layout discipline, and correctly implemented magnetic-interface circuitry. The DP83826ERHBR family is positioned for industrial Ethernet, fieldbus equipment, factory automation, industrial switches, and embedded control systems. Deterministic latency is especially valuable where predictable network response matters more than maximum aggregate throughput. The part supports copper Ethernet at 10 Mbps or 100 Mbps rather than gigabit rates, making it appropriate for legacy 10/100 infrastructure and cost-sensitive embedded links. The 5 x 5 mm RHB package uses an exposed thermal pad for improved heat transfer. Designers should follow the manufacturer's recommended power, decoupling, magnetic-component, and four-pair-differential-layout guidance because small package size alone does not guarantee signal integrity or adequate thermal performance. This page consolidates verified manufacturer and distributor information, package and lifecycle details, price data as of 2026-10-30, candidate drop-in comparisons, and practical engineering considerations. Candidate alternatives remain subject to pin-function, clocking, magnetic-interface, and firmware validation before PCB substitution.

It supports 10BASE-Te and 100BASE-TX protocols, hardware bootstrap for rapid link establishment, fast link-drop detection, and a dedicated reference CLKOUT for synchronizing other system modules. An Ethernet PHY is a physical-layer semiconductor that translates digital MAC data into signals suitable for twisted-pair cabling and recovers incoming signals for the network controller. Within the hardware hierarchy, the DP83826ERHBT is an interface IC, network interface controller, Ethernet transceiver, and physical-layer PHY. It connects an Ethernet MAC or embedded processor to a 10BASE-Te or 100BASE-TX network while supporting both MII and RMII host interfaces. The device is designed around predictable industrial-network behavior rather than only conventional throughput. Its low and deterministic latency supports real-time Ethernet systems, while low-power operation helps control system demand. Hardware bootstraps support fast link-up times, and configurable fast link-drop detection modes can improve recovery after network disturbances. The dedicated reference clock output provides a convenient synchronization source for modules elsewhere in the system. The DP83826E family supports 10-Mbps and 100-Mbps Ethernet operation for industrial automation, factory equipment, networking equipment, embedded control, communications infrastructure, and test systems. Its MII interface suits designs requiring parallel digital signaling, while RMII reduces host pin requirements in compact embedded designs. The enhanced operating mode provides additional configuration options for demanding industrial applications. A primary design consideration is the relationship between PHY configuration, MAC timing, magnetic-interface components, and the industrial network topology. The PHY must be matched to the magnetics and cabling environment, while reset, interrupt, reference-clock, and strap configuration must be reviewed against the host processor power-up sequence. Controlled impedance routing and a suitable low-noise supply arrangement are also important for maintaining reliable data transmission. This page combines verified manufacturer and distributor information, package details, commercial availability, drop-in family alternatives, and application-oriented engineering guidance. It distinguishes verified facts from unavailable values so designers can identify where a datasheet review, PCB footprint check, or component-level cross-reference is still required before release to manufacturing.
DP83826IRHBR - 10/100 Ethernet PHY | Texas Instruments
The Texas Instruments DP83826IRHBR is a deterministic, low-latency, low-power 10/100 Mbps Ethernet physical-layer transceiver with an MII interface, operating from -40°C to 85°C in a 32-pin VQFN RHB package. It supports 10BASE-T and 100BASE-TX Ethernet protocols for industrial systems requiring predictable packet timing and compact networking hardware. An Ethernet PHY is the physical-layer interface between a network controller and twisted-pair cabling. It converts digital frames supplied by an Ethernet MAC into electrical signals for 10BASE-T or 100BASE-TX links, while receiving and decoding incoming signals. Within the network hierarchy, the DP83826IRHBR is an Ethernet interface IC and physical-layer transceiver below the MAC controller, suitable for industrial Ethernet, factory automation, embedded control, and real-time communications equipment. Verified device information identifies a 10/100 Mbps data rate, MII interface, enhanced operating mode, and industrial temperature range of -40°C to 85°C. The device is supplied in a 32-pin VQFN RHB package with a 5 mm by 5 mm footprint. The MII interface provides a conventional parallel connection to an Ethernet MAC, allowing the PHY to be paired with suitable embedded processors or industrial network controllers. The DP83826 family emphasizes deterministic and low-latency operation as stated by Texas Instruments. These characteristics are relevant to industrial networks where variable communication delay can affect machine timing, motion control, monitoring, or supervisory systems. Its low-power design also makes it suitable for embedded equipment where Ethernet connectivity must be added without imposing the operating cost and switching noise of higher-rate alternatives. Typical use cases include industrial Ethernet controllers, factory automation equipment, industrial switches, programmable logic controllers, test systems, and embedded control panels. In these systems, the DP83826IRHBR can bridge an MII-capable MAC to a 10BASE-T or 100BASE-TX copper network while operating across the full industrial temperature interval. System designers should still validate cable reach, magnetic-component selection, clocking, termination, and network timing against the manufacturer documentation. The most important PCB consideration is the high-speed analog and digital interface implementation around the PHY. Place network magnetics and supporting passives according to the reference layout, keep copper paths compact, provide clean supply and ground connections, and observe the required decoupling arrangement. Those measures help control return-path discontinuity, coupling, and signal-integrity degradation around the MII and copper-network interfaces. This page consolidates the verified manufacturer identity, ordering information, package details, temperature range, pricing reference, cross-reference results, and practical design considerations for DP83826IRHBR. It also distinguishes documented facts from parameters that require confirmation in the full Texas Instruments datasheet, helping engineers make faster but more defensible Ethernet-PHY selections.
