Texas Instruments DP83867CSRGZR is a robust, low-power, fully featured Gigabit Ethernet Physical Layer transceiver (PHY) supporting 10BASE-Te, 100BASE-TX, and 1000BASE-T Ethernet protocols with RGMII and SGMII MAC interface options, packaged in a 48-pin VQFN (RGZ) 7x7 mm footprint. The device integrates the PMD sublayer and exceeds 8 kV IEC 61000-4-2 ESD (direct contact) immunity, targeting factory automation, motor drives, and other electrically harsh industrial environments. SGMII support enables seamless connection to MACs that lack parallel MII/GMII/RGMII pins, simplifying board routing on space-constrained designs. An Ethernet PHY (Physical Layer transceiver) is the analog front-end of an Ethernet link: it sits between the RJ45/magnetics on the line side and the MAC controller on the host side, performing PCS/PMA encoding, clock/data recovery, echo/ crosstalk cancellation, and link training. As a sub-class of network interface IC, the PHY falls under the broader hierarchy of networking ICs > interface ICs > integrated circuits. The DP83867CS series specifically targets the industrial Gigabit PHY niche where high ESD immunity, wide temperature support, and small form factor matter. Key features include configurable I/O voltage (3.3 V, 2.5 V, 1.8 V) for direct connection to FPGAs, SoCs, and ASICs of any logic family; ultra-low RGMII latency (TX < 90 ns, RX < 290 ns) which is essential for Time Sensitive Network (TSN) compliant systems; integrated cable diagnostics; and JTAG boundary scan support. The device ships in a 48-pin VQFN (RGZ) package with exposed thermal pad, and supports an extended industrial operating temperature range. The CS variant offers a low-power 457 mW typical operating power profile. Typical applications include industrial Ethernet switches, programmable logic controllers (PLCs), human-machine interfaces (HMIs), motor and motion control, factory automation backbones, and embedded networking on single-board computers. The wide operating temperature range and ESD robustness also make it well suited to outdoor PoE end-points and ruggedized IoT gateways where commercial-grade PHYs would be unreliable. Designers should refer to the manufacturer datasheet for the recommended magnetics, RJ45 integration, and reference clock selection, and should follow the IBIS model for SI-validated board layout.

The Texas Instruments DP83867CSRGZT is a low-power, robust, fully-featured Gigabit Ethernet Physical Layer transceiver with integrated PMD sublayers supporting 10BASE-Te, 100BASE-TX, and 1000BASE-T Ethernet protocols, offered in a 48-pin VQFN (RGZ) 7x7 mm package. Key headlines: 10/100/1000 Mbps operation, RGMII and SGMII MAC interface options, configurable I/O voltage (3.3 V, 2.5 V, 1.8 V), and an industrial-grade 0 C to 70 C operating range with TI's high-immunity PHY core. An Ethernet PHY (Physical Layer transceiver) is the analog/digital mixed-signal device sitting between a Media Access Controller (MAC) and the magnetics/RJ45 connector on a copper Ethernet link. The PHY handles line encoding/decoding (PAM-5 for 1000BASE-T, MLT-3 for 100BASE-TX), link training, echo cancellation, and cross-talk mitigation across four twisted pairs, while presenting a parallel or serial digital interface to the MAC. As a Physical Layer transceiver within the seven-layer OSI model, the PHY is part of the wired networking interface layer, and a critical power-management and signal-integrity IC in any embedded Ethernet design. Key features include cable diagnostics, low RGMII latency (TX < 90 ns, RX < 290 ns), Time-Sensitive Network (TSN) compliance, fast link drop mode, JTAG 1149.1 boundary scan support, and integrated PMD sublayers. The DP83867CS provides high ESD/EMC immunity and an ultra-low RGMII latency profile. Compared to integration assemblers using lower-immunity PHYs, the CS variant offers enhanced robustness for noisy industrial environments. Architecturally, the device uses TI's proprietary DSP-based echo canceller and baseline wander corrector across all four pairs, with auto-negotiation and Auto-MDIX, allowing direct connection to either a straight-through or crossover cable. The SGMII option reduces MAC-to-PHY pin count to four differential signals, freeing board area in space-constrained designs. Typical applications include industrial Ethernet switches, factory automation controllers, motor drives with EtherCAT/PROFINET support, building automation, and any embedded system requiring a small-footprint, low-power gigabit copper interface. The wide temperature range and immunity rating make the part especially suitable for industrial Ethernet switches and PLCs. When designing with this device, pay careful attention to MDI trace routing (100-ohm differential, length-matched within the pair), magnetics selection, and decoupling on each supply pin. Reference the TI DP83867 design checklist for layout guidance, especially the four-pair MDI routing and chassis-ground separation.
DP83867E - Gigabit Ethernet PHY, RGMII/SGMII, 48-VQFN | TI
The Texas Instruments DP83867E is a robust, low-power, fully-featured 10/100/1000 Mbps Ethernet Physical Layer transceiver with integrated PMD sublayers, supporting 10BASE-Te, 100BASE-TX, and 1000BASE-T Ethernet protocols, housed in a 48-pin VQFN (7x7 mm) package. The device delivers extra-low latency (TX < 90 ns, RX < 290 ns) and is offered in an industrial extended-temperature grade with SGMII and RGMII MAC interfaces. An Ethernet PHY (Physical Layer transceiver) is a mixed-signal IC that connects a MAC controller to the copper medium (twisted-pair cable), handling line encoding/decoding, link training, echo/next-crosstalk cancellation, and clock/data recovery across the MDI. The DP83867E sits at the bottom of the OSI physical layer, translating digital MAC frames into analog baseband signals on the cable. In the taxonomy: Ethernet PHY -> transceiver -> network interface IC -> communication semiconductor. The part exceeds 8 kV IEC 61000-4-2 ESD on the cable pins, making it a robust choice for industrial and automotive-grade Ethernet links. Key features include support for both RGMII and SGMII MAC interfaces, integrated 1.25 GHz SerDes for SGMII, low-power 1000BASE-T operation, programmable LED outputs, and a flexible MDIO/MDC management interface. The extended-temperature grade (-40C to +105C ambient with proper thermal design) targets industrial control, factory automation, and outdoor equipment where commercial-grade PHYs derate. Architecturally, the DP83867E uses a DSP-based echo and crosstalk canceller, an integrated 1000BASE-T PMA/PMD with on-chip termination, and a low-jitter PLL to recover the 125 MHz reference. The SGMII variant routes the recovered data over a 1.25 Gbps differential serial link, eliminating the 12-bit parallel RGMII bus and reducing board-layer routing complexity in space-constrained SoMs. Typical applications include industrial Ethernet switches, programmable logic controllers (PLCs), factory-floor IO modules, motor drives, telecom base-station routers, and automotive Ethernet PHYs for in-vehicle networking. The SGMII interface in particular suits SoCs that place the PHY on a remote daughter card or that prefer serial MAC connectivity. Design consideration: the MDI traces require 100-ohm controlled differential impedance and an integrated magnetics RJ-45 with center-tap; the 1.0 V analog and 2.5/3.3 V digital rails must be cleanly decoupled to meet the IEEE 802.3 return-loss mask. Use the TI reference design checklist for BOM and stack-up. This page synthesizes distributor pricing, package-accurate cross-references, and practical PCB design notes that go beyond the manufacturer datasheet to accelerate your Ethernet hardware bring-up.

The extended-temperature ordering option operates from -40 °C to 105 °C, making the device suitable for industrial embedded networking and communications equipment that requires extended environmental coverage. An Ethernet physical-layer transceiver, commonly called an Ethernet PHY, is the circuit that converts digital Ethernet data between a MAC or communications processor and a physical copper network. The DP83867E belongs to the Gigabit Ethernet PHY hierarchy: Ethernet transceiver > physical-layer transceiver > PHY > semiconductor. Its 10BASE-T, 100BASE-TX, and 1000BASE-T support allows one physical network interface to accommodate 10 Mb/s, 100 Mb/s, and 1 Gb/s Ethernet operation, depending on the link negotiation and connected equipment. The verified ordering information identifies a 48-VQFN RGZ package, a 7 mm square land pattern, a 0.5 mm lead pitch, and a tape-and-reel shipping format. RGMII provides a parallel digital interface for a conventional MAC-to-PHY connection, while SGMII provides a high-speed serial interface for designs that benefit from fewer signal connections. The available comparison data also identifies cable-diagnostics, IEEE 1588 support of the stated SOF type, and JTAG 1149.1 among the notable device features. Because the DP83867ERGZR is specified as an extended-temperature, robust, low-latency Gigabit Ethernet PHY, it is relevant to industrial automation, motor-drive systems, embedded routers, test equipment, and communications infrastructure. These systems benefit from a compact 48-pin surface-mount package and flexible RGMII or SGMII host connectivity. The exact supported link rates, electrical characteristics, clocking requirements, media-access procedures, and recommended external circuitry must be confirmed against the manufacturer datasheet before a board design is released. A critical implementation consideration is that the PHY is part of a high-speed mixed-signal system. Designers should follow the manufacturer’s reference layout, provide the specified power and decoupling networks, and route high-speed differential pairs as controlled-impedance transmission lines. Magnetics, RJ45 circuitry, clock sources, reset timing, and the exact operating mode also require validation in the complete system rather than substitution based only on package similarity. This page consolidates the verified manufacturer and distributor information for DP83867ERGZR, adds application and design context, distinguishes documented facts from missing technical data, and evaluates only same-package drop-in candidates that can be traced to the supplied web results. It is intended to accelerate component screening while preserving the need for datasheet-level engineering verification before procurement or PCB release.

Unlike a software-only MAC, the PHY performs the physical encoding, signaling, and recovery associated with copper Ethernet. The SGMII option is particularly useful when the PHY must connect across a serial high-speed digital interface, while RGMII provides a wider parallel interface for designs using a local processor or FPGA. Typical uses include industrial Ethernet switches, programmable logic controller gateways, factory automation controllers, network-attended test equipment, embedded systems, and rugged communications infrastructure. It is also appropriate for designs requiring a compact, single-port Gigabit Ethernet interface without the footprint of a larger multi-port transceiver. Designers should carefully follow the manufacturer reference layout for the exposed-pad package, provide the specified power and decoupling networks, and use a qualified Ethernet transformer with the required center-tap and termination arrangement. RGMII timing is especially sensitive to trace length and clock skew, while SGMII requires controlled impedance and low-jitter routing. Magnetics selection, isolation boundaries, grounding, and surge protection must be reviewed against the target installation environment.

Electrostatic-discharge robustness is a central feature of the device. According to the TI datasheet, the DP83867 exceeds 8 kV IEC 61000-4-2 direct-contact ESD protection. This makes the transceiver suitable for connectivity equipment installed near externally accessible cables, provided the board-level protection network, grounding, and layout guidance in the manufacturer datasheet are followed. The package also uses 1 V, 1.8 V, and 2.5 V digital I/O levels, allowing interface-voltage selection based on the connected Ethernet controller. Typical uses include industrial switches, routers, gateways, embedded network modules, test equipment, and communication equipment requiring a single copper-Ethernet port. RGMII is useful when the PHY is placed beside an Ethernet MAC in a high-performance system, while SGMII can simplify connections to serializers or controllers that support that interface. The same PHY can negotiate the link rate and support 10BASE-T, 100BASE-TX, or 1000BASE-T operation according to the connected network. A successful design must preserve high-speed signal integrity around the RGMII, SGMII, clock, and differential copper interfaces. Place decoupling capacitors close to the supply pins, use the recommended magnetics and impedance-controlled differential routing, and follow the exposed-pad thermal and assembly requirements. Do not substitute a non-drop-in transceiver solely because its headline data rate matches. This page organizes the manufacturer specifications, sourcing information, drop-in family options, application guidance, package constraints, and practical PCB considerations needed to evaluate DP83867ISRGZR before committing it to a design.

The device integrates the physical-medium dependent sublayers required for 10BASE-T, 100BASE-TX, and 1000BASE-T operation. Supporting all three rates in one PHY permits a single copper-network design to accommodate legacy 10 Mbit/s and 100 Mbit/s endpoints as well as full-duplex Gigabit links. The availability of 1.0 V, 1.8 V, and 2.5 V interface rails supports integration with processors, FPGAs, switching fabrics, and industrial controllers operating at different logic levels. Typical applications include industrial Ethernet controllers, factory automation equipment, networked sensors, motor-drive systems, building-automation gateways, and embedded routers. The combination of RGMII and SGMII makes the device suitable for designs that must accommodate parallel MAC connections, serial fabric links, or platform variants using different network architectures. PCB implementation requires careful treatment of the exposed pad, analog supply rails, clock sources, and high-speed digital interfaces. Place the PHY close to the network connector and magnetics, route differential pairs as impedance-controlled pairs, and use a solid ground-plane arrangement beneath the device. Follow the manufacturer datasheet for the exposed-pad connection, decoupling capacitors, isolation boundaries, and analog-layout requirements. This page organizes the DP83867ISRGZT’s industrial Ethernet role, interface options, temperature range, package constraints, application guidance, drop-in candidates, and engineering considerations into a practical selection reference for designers building robust copper-based Ethernet equipment.
DP83869HMRGZR - High-Immunity Gigabit Ethernet PHY | TI
The Texas Instruments DP83869HMRGZR is an extended-temperature, high-immunity gigabit Ethernet PHY transceiver with integrated PMD sublayers, supplied in a 48-pin VQFN (RGZ) 7x7 mm package. It supports 10BASE-Te, 100BASE-TX, and 1000BASE-T copper protocols along with 1000BASE-X and 100BASE-FX fiber interfaces, operating from a 1.8V/2.5V/3.3V supply rail. An Ethernet PHY (Physical Layer transceiver) is the interface IC that connects a MAC (Media Access Controller) to the physical copper or fiber cable, handling line coding, link training, echo/return-loss compensation, and clock/data serialization. As part of the Physical Layer transceiver -> Ethernet transceiver -> Network Interface IC -> Power Management/Connectivity IC hierarchy, gigabit PHYs sit one layer below the MAC and one layer above the magnetics/RJ-45 (or SFP fiber cage), translating MII/GMII/RGMII parallel data into differential serial signals compliant with IEEE 802.3 10/100/1000BASE-T. Key features of the DP83869HMRGZR include: IEEE 802.3 10/100/1000 Mbps operation, integrated PMD sublayers for copper and fiber, RGMII/MII/GMII MAC interfaces, media-conversion between copper and fiber ports, AEC-Q100-qualified extended-temperature grade (-40C to +125C), low-latency cut-through mode, and 8 kV IEC 61000-4-2 ESD protection (direct contact). The 48-pin VQFN (RGZ) package exposes a thermal pad for heat dissipation and supports reflow soldering on standard industrial PCB processes. Architecturally, the DP83869HMRGZR integrates the entire physical coding sublayer (PCS), physical medium attachment (PMA), and physical medium dependent (PMD) blocks on-chip, eliminating the need for external PHY magnetics tuning circuits. The device supports both SGMI and RGMII host interfaces with selectable timing modes, and includes integrated termination resistors that simplify the BOM. Cable diagnostics, loopback modes, and jumbo-frame support extend its utility in industrial Ethernet switches. Typical applications include industrial Ethernet switches, factory automation controllers, motor-drive communication boards, 5G small-cell fronthaul, automotive Ethernet gateways, and fiber-to-copper media converters. The wide temperature and high immunity make it well suited for IEC 61000-4 industrial EMC environments where standard PHYs would fail conformance. When designing with this part, ensure the MDI traces are 100-ohm differential with controlled 50-ohm single-ended impedance, place the 1.8V/2.5V/3.3V decoupling capacitors within 2 mm of each supply pin, and use a 4-layer PCB with a continuous ground plane below the PHY to meet IEEE 802.3 return-loss masks. This page synthesizes distributor pricing, drop-in TI same-family alternatives, design notes, and an honest comparison against cross-brand gigabit PHYs - content not aggregated on any single manufacturer or distributor page.
DP83901AV - 5V Serial Network Controller | Texas Instruments
The Texas Instruments DP83901AV is a 5 V serial network interface controller, or SNIC, with 110 mA typical supply current in a 68-pin PLCC J-lead package measuring 25.13 mm by 25.13 mm. Designed for CSMA/CD local-area networks, the device supports Ethernet 10BASE5, Thin Ethernet 10BASE2, and twisted-pair Ethernet 10BASE-T implementations. A serial network interface controller is a semiconductor that coordinates data exchange between a host computer and an Ethernet physical layer. Within the network-interface hierarchy, it sits between host hardware or software drivers and a network-medium transceiver. The DP83901AV consolidates functions required to manage Ethernet packet transfer, addressing, access, and station communication while operating from a single 5 V supply. The verified source material identifies the DP83901AV as a microCMOS VLSI controller with a serial interface, 7 pF typical input capacitance, and 7 pF typical output capacitance under the stated test conditions. Its nominal 110 mA supply current makes board-level power planning important in systems that operate continuously. Commercial temperature grade and tray packaging are also identified in the verified component listings. Because the part targets legacy Ethernet standards, its strongest design roles are 10BASE5, 10BASE2, and 10BASE-T network-interface designs rather than modern switched Gigabit Ethernet equipment. A host processor must provide the required bus, interrupt, memory, and network-driver environment. Designers should also preserve the exact timing, signal-conditioning, and pin functions documented for this legacy controller. Typical implementation choices include industrial data acquisition, embedded test systems, service equipment, and legacy Ethernet adapters that require 10BASE-T connectivity. The controller can be paired with suitable transceivers, magnetics, isolation, clocks, and termination networks, but the external network interface must be selected independently because the verified data does not identify one specific companion-device BOM. The primary design consideration is availability and lifecycle validation. This is a mature Ethernet controller, so procurement should confirm current supply, manufacturer status, and traceability before a new design is released. Existing products should preserve the original schematic, timing, and firmware assumptions unless a replacement has been independently qualified. This page consolidates the verified package, supply, interface, and Ethernet data while separating unavailable specifications from established facts. It also records the lack of a verified drop-in replacement rather than presenting a functionally similar controller as a safe PCB substitute.
DP83902AV/NOPB - 10BASE-T Ethernet Controller
Texas Instruments DP83902AV/NOPB is an IEEE 802.3 serial network interface controller for 10BASE-T twisted-pair Ethernet, with a 4.75 V to 5.25 V supply range, 140 mA supply current, and an 84-pin PLCC package measuring 29.31 mm by 29.31 mm. It integrates the network-controller and twisted-pair transceiver functions required by legacy 10 Mb/s Ethernet systems. An Ethernet controller is an interface IC that connects a host or embedded system to a physical-layer network. The DP83902AV/NOPB belongs to the ST-NIC family and is intended for IEEE 802.3 10BASE-T networking. Unlike a switching Ethernet transceiver designed for modern 100 Mb/s or multi-gigabit links, this device targets legacy 10BASE-T equipment where established system architecture and installed cabling remain important. The device operates from a conventional 5 V supply, accepting voltages from 4.75 V through 5.25 V. Its specified supply current is 140 mA. The package is an 84-pin J-lead PLCC with a 29.31 mm by 29.31 mm body, and the documented shipping format is a tube. The suffix NOPB identifies a lead-free ordering configuration associated with this manufacturer’s RoHS-compliant product documentation. DP83902AV/NOPB combines the logical Ethernet controller and 10BASE-T physical interface in one integrated circuit. This integration reduces the number of network-interface components required in a conventional 10BASE-T design. The serial interface is consistent with the ST-NIC architecture used in IEEE 802.3 systems, allowing the controller to serve as the principal interface between host-side logic and the twisted-pair physical layer. Typical uses include legacy network interface cards, embedded industrial Ethernet equipment, test systems, and industrial-control products whose original architecture was designed around the IEEE 802.3 10BASE-T standard. The device may also appear in equipment maintenance and obsolescence programs where preserving the original 84-pin PLCC footprint is preferable to redesigning the network interface. A replacement decision should prioritize the complete pinout, electrical characteristics, clocking arrangement, media-access behavior, and software-driver expectations. Do not assume that another Ethernet controller is interchangeable solely because it also supports 10BASE-T. A qualified replacement must preserve the 84-pin PLCC land pattern and the original system-level timing and register requirements. This product page combines the controller identity, operating limits, package information, verified drop-in information, comparison parameters, and engineering selection guidance. That practical context helps engineers distinguish a genuine footprint-compatible replacement from a merely similar Ethernet interface before committing to a redesign.
DP83902AVLJ - 5V Serial Network Controller | Texas Instruments
The Texas Instruments DP83902AVLJ is a serial network interface controller for twisted-pair networks, supplied in a 100-lead rectangular QFP package and operating from a 4.75 V to 5.25 V supply. Its listed characteristics include a serial interface, approximately 140 mA supply current, commercial temperature grade, and tray packaging. The device is described by Texas Instruments as an ST-NIC serial network interface controller and is categorized as an obsolete interface controller. A serial network interface controller is an integrated circuit that manages the communication path between a computer or embedded system and a network medium. In the product hierarchy, this controller belongs to interface ICs and ultimately to the broader semiconductor category. The DP83902AVLJ was designed around twisted-pair network connectivity, where a physical-layer transceiver is commonly paired with a controller. The controller handles network framing and data exchange, while the external transceiver performs signal encoding, reception, and electrical isolation from the copper medium. The DP83902AVLJ uses a 4.75 V minimum and 5.25 V maximum supply voltage, giving system designers a nominal 5 V operating rail. The verified distributor listing reports a supply current of 140 mA. Its 100-pin QFP package provides a substantial number of external connections, which is typical for legacy Ethernet controllers that require parallel host data paths, address and control signals, clocking, interrupt signaling, and twisted-pair transceiver interfaces. Package dimensions, pin names, operating-temperature limits, Ethernet data rate, transceiver interface details, and electrical timing limits are not included in the supplied verification data. The DP83902AVLJ is most relevant to legacy networking equipment, industrial control systems, embedded controllers, and industrial Ethernet designs that already use this controller and its associated application circuitry. It should not be assumed interchangeable with a modern Ethernet controller merely because both perform networking functions. The verified cross-reference material specifically states that the STMicroelectronics SERC816/TR is not a direct drop-in replacement because its pinout, internal biasing, and MII timing characteristics differ. A PCB replacement therefore requires a detailed electrical, timing, and pin-level review rather than a simple component substitution. This page consolidates the verified distributor specifications, lifecycle information, sourcing details, and replacement constraints for DP83902AVLJ. Pricing is presented as unavailable because the verified sources provide quote or request-for-quotation terms rather than numeric unit prices. The pin table records all 100 package terminals but marks individual terminal names as unavailable rather than guessing pin functions. Engineers should obtain the manufacturer datasheet and original design reference before layout changes, firmware updates, or obsolescence redesigns.
DP83905AVQB - 10BASE-T Ethernet Controller | Texas Instruments
The Texas Instruments DP83905AVQB is an AT/LANTIC AT local-area-network twisted-pair interface controller with an integrated IEEE 802.3 10BASE-T PHY, an ISA interface, and a 160-pin QFP package measuring 28 mm by 28 mm. It operates from a single 4.75 V to 5.25 V supply and is specified for 0 °C to 70 °C commercial-grade operation. An Ethernet controller integrates the digital protocol, media-access, and physical-layer functions needed to connect a legacy personal computer or embedded ISA bus to a 10BASE-T twisted-pair network. The DP83905 supports the AT/LANTIC protocol family, IEEE 802.3 operation, and 10BASE-T signaling. Because the physical layer is integrated, a compliant design can use the controller with the appropriate line-driver, filter, isolation, and magnetics interface rather than implementing the complete PHY separately. Verified device attributes include a 4.75 V to 5.25 V supply range, nominal 100 mA supply current, IEEE 802.3 network support, 10BASE-T PHY operation, ISA host interfacing, a commercial temperature grade of 0 °C to 70 °C, and a 160-BFQFP package. The device is identified as obsolete in the supplied manufacturer-related documentation, so it is most appropriate for maintenance of legacy AT-compatible networking equipment rather than new mass-production designs. The DP83905AVQB belongs to the former National Semiconductor controller portfolio now served by Texas Instruments. Its large 160-pin gull-wing QFP construction is characteristic of late-1980s and early-1990s PC interface controllers, when integrating the AT bus logic, network controller, and 10BASE-T PHY into one device reduced component count and simplified legacy adapter-card design. Typical uses include industrial legacy controllers, AT-compatible Ethernet adapters, embedded data-acquisition systems, and repair or obsolescence-management programs for installed networking equipment. The ISA interface and 10BASE-T speed make the device most suitable for systems that already rely on the AT/LANTIC environment; it is not a modern 100BASE-TX or gigabit Ethernet controller. When replacing this component, engineers should verify the complete 160-pin footprint, exposed pad requirements, power rails, oscillator components, magnetics isolation, and legacy bus termination before substituting. Because this part is obsolete and few verified pin-compatible replacements are documented, board-level redesign to a current Ethernet controller may be safer than assuming equivalent availability.
DP83907VF - 10Base-T Ethernet NIC Controller ISA Interface | TI
The Texas Instruments DP83907VF (AT/LANTIC II) is a single-chip CMOS VLSI 10Base-T Ethernet Network Interface Controller (NIC) with integrated ISA bus interface, delivered in a 132-pin BQFP (PQFP) package. It supports a single 10 Mb/s twisted-pair or coaxial channel, operates from a single 5V supply (4.75 V to 5.25 V) drawing approximately 150 mA, and is qualified to the commercial temperature range. What is an Ethernet NIC controller? A NIC controller is an integrated circuit that bridges a host processor's parallel bus (such as ISA, PCI, or PCIe) to a Media Access Control layer that implements the CSMA/CD protocol used by IEEE 802.3 Ethernet. The DP83907 sits in the hierarchy: 10Base-T PHY → Ethernet MAC → NIC controller → host bus controller → PC motherboard. By integrating the entire PC-AT ISA bus interface along with the MAC and 10 Mb/s physical front-end, the DP83907 reduces discrete component count and lets designers add a 10 Mb/s LAN port with minimal glue logic. Key features of the DP83907VF include on-chip Manchester encoder/decoder for 10Base-T, integrated 10Base-T transceiver (twisted-pair), built-in attachment unit interface (AUI) for external MAU support, full ISA (Industry Standard Architecture) 8/16-bit bus mastering DMA engine, and configurable I/O and memory mapped modes. The device offers a 2-channel CSMA/CD link, supporting 1.25 MBps raw throughput on the serial side. CMOS process technology keeps power dissipation under 1W typical. Architecturally, the DP83907VF partitions cleanly into a bus interface unit, a CSMA/CD MAC engine, a Manchester ENDEC, and a 10Base-T analog front end. The MAC performs framing, CRC-32 generation/checking, collision detection, and back-off timing, while the analog front-end provides transmit waveshaping and receive equalization for 100-meter Category-3 cable runs. The combination targets PC-AT/PC/XT motherboards, ISA add-in cards, embedded LAN adapters, and industrial 10 Mb/s backbones. Typical applications include ISA-bus Ethernet NIC add-in cards, factory-floor 10Base-T bridges, industrial automation controllers with embedded LAN ports, legacy PC motherboard LAN-on-board designs, and 10 Mb/s repeaters/hubs requiring a host-managed controller. Because the part integrates the AUI option, it can also drive an external 10Base2 (BNC) transceiver for coax-based legacy LANs. When designing with the DP83907VF, plan ISA bus arbitration because bus-master DMA requires care to coexist with other bus masters. Add 4.7 kΩ pull-ups on configured strap inputs (IRQ, I/O base address) and keep the analog ground (AGND) and digital ground (DGND) separated under the package, joining them only at the PCB main ground plane to preserve 10Base-T jitter margins. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes not found in the manufacturer datasheet alone.
DP8390DV - 10 Mbps 5 V Ethernet NIC | Texas Instruments
The Texas Instruments DP8390DV is a 10 Mbps, 5 V Ethernet network interface controller supplied in a 68-pin PLCC package measuring 25.13 mm by 25.13 mm. It is designed to interface host systems with CSMA/CD local-area networks, including Ethernet Thin implementations, while presenting a dedicated network-controller function rather than requiring the host processor to manage the physical network medium directly. The verified distributor listing identifies the device as an Ethernet controller interface and describes its 68-PLCC construction. What is an Ethernet network interface controller? An Ethernet NIC is an interface IC positioned between a computer or embedded controller and an Ethernet physical layer. It handles network-oriented communication tasks and reduces the electrical and protocol burden placed on the host system. In the broader semiconductor hierarchy, the DP8390DV is a communication interface controller, an interface IC, and ultimately a semiconductor used in Ethernet networking equipment and embedded data-processing systems. The DP8390DV’s primary verified characteristics include a 10 Mbps data rate, a 5 V supply, and approximately 40 mA supply current. Those values place it in the established 10BASE-T-era Ethernet hardware category. Its PLCC package provides a surface-mount PCB footprint with J-leads, while the listed 25.13 mm by 25.13 mm body size supports compact but not especially miniature industrial and legacy-compatible designs. DP8390D-family devices were designed to ease host interfacing with CSMA/CD local-area networks, including Ethernet Thin networks. The controller therefore belongs in systems where a host bus must communicate through an Ethernet-compatible network interface. Compared with a general-purpose interface IC, its defining value is Ethernet-specific integration: the network function is consolidated into a dedicated controller rather than being implemented entirely with host firmware and discrete logic. Typical uses include embedded Ethernet controllers, industrial data-acquisition systems, legacy terminal equipment, print servers, network-interface modules, and host adapters designed around the DP8390 family. In these applications, the DP8390DV can serve as the network-facing IC while an external transceiver, magnetic interface, connector, and system controller provide the surrounding physical-layer and host-side implementation. The principal design consideration is that this is a mature 10 Mbps controller rather than a current multi-gigabit Ethernet PHY or modern system-on-chip interface. Board design must follow the manufacturer pinout and required external components exactly. Signal routing, supply decoupling, thermal exposure, and network magnetics or transceiver selection should be validated against the official DP8390 documentation before layout release. This page consolidates verified distributor specifications, sourcing information, interface context, and application guidance. It does not invent unprovided pin assignments, timing values, temperature limits, or replacement parts, so unavailable engineering data remains explicitly marked rather than being inferred.
DP83910AN - CMOS Serial Network Interface 24-DIP | National Semiconductor
The National Semiconductor (Texas Instruments) DP83910AN is a CMOS Serial Network Interface (SNI) IC that provides Manchester data encoding and decoding for IEEE 802.3 Ethernet networks, supplied in a 24-pin DIP through-hole package (0.300 inch, 7.62 mm body width) and operating from a single 4.75 V to 5.25 V supply. The device is a direct-pin functional replacement for the legacy bipolar DP8391 SNI, integrating the physical-layer attachment functions required to interface an Ethernet transceiver (such as the DP8392 or DP839CT) to a controller or terminal-end Manchester encoder/decoder across 10 Mb/s Thin Ethernet (10BASE2/10BASE5) topologies. A Serial Network Interface (SNI) is a category of interface IC that sits between the Ethernet coaxial transceiver and the system controller, performing Manchester encoding, clock recovery, jabber monitoring, and link-integrity signalling per the IEEE 802.3 physical-layer specification. Within the broader hierarchy, the DP83910AN belongs to the network interface IC family, which falls under interface ICs, then integrated circuits, then semiconductors, providing OSI layer-1 connectivity and isolating the host CPU from line-coding analogue details. Key features include 10 Mb/s Manchester encoding/decoding, integrated jabber detection and Link Test generation, CMOS low-power operation versus the original bipolar DP8391, and a wide supply tolerance of 4.75 V to 5.25 V. The 24-DIP through-hole package supports easy insertion into legacy Ethernet adapter boards and industrial retrofit designs, while the CMOS process reduces typical operating current compared to its bipolar predecessor. The device also provides collision-detection and carrier-sense signalling flags that flow into the upper-layer MAC controller. Architecturally, the DP83910AN combines a phase-locked loop (PLL) for receive clock recovery, a 10 MHz oscillator interface, transmit clock-generation logic, and differential Manchester encode/decode blocks. Because the silicon is a drop-in CMOS replacement for the DP8391, existing schematic layouts can accept the DP83910AN without board rework, a critical advantage for legacy industrial networks and instrumentation that depend on the older part. Typical applications include 10BASE2 / 10BASE5 Ethernet adapter cards, industrial SCADA controllers, legacy factory-floor networking interfaces, and embedded instrumentation that must communicate over IEEE 802.3 media. The DP83910AN is also commonly used by restoration projects for early-1990s networking hardware and by test equipment vendors supporting IEEE 802.3 physical-layer compliance. When designing with this device, note that the DP83910AN is now in obsolete/EOL lifecycle, so long-term sourcing requires attention to authorized distributor stock and the qualified cross-references listed in the alternatives section. Decoupling with 0.1 uF ceramic capacitors close to VCC/GND pins is essential for the integrated PLL to maintain stable clock recovery under varying line loading. This page synthesizes distributor pricing from DigiKey and Win Source, drops-in cross-reference data, lifecycle risk analysis, and Pin Configuration design notes that go beyond what the original manufacturer datasheet provides as of October 22, 2026.
DP83910AV - CMOS SNI Ethernet Interface | Texas Instruments
The Texas Instruments DP83910AV is a CMOS Serial Network Interface (SNI) integrated circuit with a 28-PLCC J-lead package. The supplied distributor data identifies it as an Ethernet network interface operating from a 4.75 V to 5.25 V supply and supporting a commercial temperature grade of 0 C to 70 C. The DP83910A family provides Manchester data encoding and decoding functions for IEEE 802.3 Ethernet Thin Ethernet local-area networks and is described as a direct-pin equivalent of the bipolar DP8391 SNI. A Serial Network Interface is an interface integrated circuit that converts between a host-side digital data stream and the physical signaling required by a legacy Ethernet network. In the product hierarchy, SNI belongs to network interfaces, then interface ICs, then integrated circuits. Manchester encoding represents each data bit through a transition pattern, allowing the receiver to recover both the bit value and clock information from the serial waveform. This device is therefore intended for systems requiring legacy Ethernet-compatible Manchester encoding and decoding rather than a modern integrated PHY/MAC solution. The DP83910AV is specified as a 28-pin PLCC device, with the AV suffix identifying the supplied package/orderable configuration. Its 4.75 V to 5.25 V operating range is characteristic of a 5 V legacy interface implementation. Distributor listings classify the device as an Ethernet Network Interface IC, while the manufacturer-related datasheet description identifies it as a CMOS SNI Serial Network Interface. The available source data does not provide verified values for clock rate, current consumption, output timing, logic levels, or internal transceiver details. Typical engineering uses include legacy Thin Ethernet network nodes, industrial data-collection equipment, embedded test systems, and retrofits requiring compatibility with existing Manchester-encoded Ethernet hardware. In such systems, the DP83910AV can perform the Manchester encoding or decoding stage at the boundary between digital logic and the network interface. The 28-PLCC package is a legacy surface-mount format requiring a matching footprint, adequate routing clearance, and careful examination of pin orientation and thermal performance. For new designs, verify that the required legacy network architecture, voltage, timing, connector, and isolation requirements match the device. Obsolete or NRND legacy Ethernet components should be sourced only after confirming documentation, traceability, and long-term availability. The available distributor result reports 6,224 pieces in stock and a unit price of $9.5471, but price and availability should be reconfirmed at the time of purchase. This page combines verified distributor descriptions, lifecycle information, package data, and engineering-use guidance. It does not infer unprovided electrical limits or claim a substitute part where pin-level and parametric equivalence has not been established.
DP83910AV/63 - 5V Ethernet SNI Interface | Texas Instruments
The Texas Instruments DP83910AV/63 is a 5 V CMOS serial network interface IC designed for Ethernet network-interface applications, supplied in a 28-pin PLCC surface-mount package measuring approximately 11.51 mm by 11.51 mm. The device operates from 4.75 V to 5.25 V and is specified for a 0°C to 70°C temperature range. Verified distributor data identifies it as a tape-and-reel packaged Ethernet network interface with a serial interface architecture. An Ethernet serial network interface, or Ethernet SNI controller, is an interface IC within the broader network interface controller and Ethernet controller categories. Its function is to connect a host or processor-side system to Ethernet physical-layer circuitry, handling the serial-side data path and associated control signals. The DP83910AV/63 therefore belongs to the integrated-circuit hierarchy: Ethernet interface controller, network interface controller, Ethernet IC, and semiconductor. Key verified features include a 4.75 V to 5.25 V supply range, a 0°C to 70°C commercial operating-temperature range, and a 28-pin PLCC package. The source data identifies the part as an Ethernet network interface with a serial interface and CMOS construction. The verified product listing also states that the device contains lead and is not RoHS compliant. Detailed electrical characteristics such as clock frequency, transceiver-interface timing, maximum output current, and pin-level functions were not included in the supplied verified data and therefore are not asserted here. The DP83910AV/63 is primarily associated with legacy embedded Ethernet equipment, industrial controllers, communication modules, and systems requiring an IEEE 802.3-compatible Ethernet path. The surrounding system must provide the correct supply regulation, decoupling, physical-layer transceiver, isolation requirements, connector protection, and clocking. Because the verified source describes a legacy PLCC device that is not RoHS compliant, engineers should review current regulatory, availability, and lifecycle requirements before starting a new design. A key design consideration is PCB compatibility. The 28-pin PLCC footprint requires a matching surface-mount land pattern and appropriate assembly temperature controls. Do not substitute a functionally similar but mechanically different controller without verifying every pin, supply requirement, timing parameter, and signal standard. For legacy repairs, confirm whether the original board uses the /63 tape-and-reel ordering code and verify the manufacturer documentation for assembly and handling requirements. This page consolidates verified distributor facts, lifecycle-related availability information, direct substitution references, and practical selection guidance. It also distinguishes documented electrical facts from unavailable parameters so engineers can assess the DP83910AV/63 without mistributing catalog summaries for a complete datasheet specification set.
DP83910AV/63SN - 5V CMOS Ethernet SNI | Texas Instruments
The Texas Instruments DP83910AV/63SN is a CMOS serial network interface (SNI) integrated circuit for Ethernet network-interface designs, supplied in a 28-pin PLCC package measuring 11.51 mm by 11.51 mm. The device operates from a 4.75 V to 5.25 V supply, uses a commercial temperature grade, and is supplied in a tube according to the product comparison record. An SNI, or serial network interface, is an interface integrated circuit that connects networking equipment to a serial or system-side data path. Within the hardware hierarchy, the DP83910AV/63SN belongs to Ethernet interface ICs, network interface controllers, interface semiconductors, and integrated circuits. Its function is to support Ethernet-oriented network-interface implementations where a dedicated controller requires a compatible serial network interface device. The principal documented characteristics are the 4.75 V to 5.25 V operating supply, CMOS construction, 28-pin PLCC package, and 11.51 mm by 11.51 mm package dimensions. The DP83910AV/63SN carries RoHS3 status and is identified as a last-time-buy component. Engineers should therefore treat availability, lifecycle continuity, and legacy-board support as important selection factors rather than assuming a current active-production lifecycle. The DP83910A is designed as a CMOS SNI for Ethernet applications. Because this legacy device predates many integrated Ethernet controllers, it is most relevant to equipment based on established interfaces, industrial communication systems, test equipment, and embedded networking designs that retain the original system architecture. A migration to a newer Ethernet interface IC may require controller, protocol, pinout, software, and timing changes rather than a simple board substitution. Typical uses include legacy Ethernet network-interface adapters, industrial control equipment, embedded communication controllers, test and measurement systems, and data-acquisition equipment. In these applications, the SNI can serve as the network-facing interface component while a host processor or communications controller manages packet processing and higher-level protocol functions. The 5 V supply range also supports equipment architectures that already provide a regulated 5 V rail. When designing around the DP83910AV/63SN, begin with the manufacturer datasheet pin-description table, supply recommendations, and timing diagrams. PLCC lead pitch, exposed underside geometry, solder-profile requirements, and thermal performance should be checked against the PCB footprint before layout approval. Because the device is in last-time-buy status, consider long-term procurement and a documented second-source strategy for maintenance programs. This page organizes the known electrical, package, lifecycle, commercial, and replacement information for engineering review. It also highlights verified direct-substitute information and explains where an existing Ethernet design may require architectural changes instead of a pin-compatible replacement.
DP83910AV/NOPB - CMOS Ethernet SNI | Texas Instruments
Texas Instruments DP83910AV/NOPB is a CMOS serial network interface (SNI) integrated circuit for Ethernet network equipment, with a 4.75 V to 5.25 V supply range and a 28-pin PLCC package measuring 11.51 mm by 11.51 mm. The device provides Manchester data encoding and decoding functions while remaining a direct-pin equivalent of the bipolar DP8391 serial network interface. A serial network interface is an interface IC that connects a digital system to a physical network encoding. Manchester encoding represents each bit through a transition in the signal, allowing the receiver to recover both data and timing. Within the broader semiconductor hierarchy, the DP83910AV/NOPB is an Ethernet interface IC, a serial interface device, and a network interface component designed for 5 V digital equipment. Key features include CMOS construction, serial Manchester encoding and decoding, a 4.75 V minimum operating supply, a 5.25 V maximum operating supply, and compatibility with the pin arrangement of the original bipolar DP8391 interface. Its commercial temperature classification, J-lead terminal form, 28-terminal square package, and tube packaging are identified in manufacturer and distributor technical listings. The DP83910A implementation replaces the bipolar technology used by the earlier DP8391 while retaining direct-pin equivalence. This distinction is important in legacy and industrial Ethernet designs because a board can retain its established land pattern and signal architecture while moving from a bipolar interface to CMOS. The 28-PLCC construction also supports through-hole assembly and removal or replacement with conventional PLCC handling equipment. Typical uses include Ethernet network interface cards, embedded Ethernet equipment, industrial controllers, data acquisition systems, and legacy network adapters that require Manchester-coded serial signaling. The appropriate operating environment must stay within the stated 4.75 V to 5.25 V supply range. Board-level design should also preserve the original DP8391-compatible clock, transmit, receive, and control arrangements when reusing an existing footprint. For a new design, begin with the manufacturer pin-description and application information rather than treating the direct-pin statement as permission to change system timing. Decoupling, impedance-controlled network connections, grounding, and signal routing should follow the circuit shown in the manufacturer datasheet. In a legacy replacement, verify the installed DP8391 or DP83910A markings and compare supply voltage, temperature grade, and package orientation before production use. This page combines the verified package, supply, interface, technology, and compliance details with replacement guidance and practical implementation considerations. It also identifies the limitations of the available drop-in choices: the closest documented replacement is the same manufacturer's DP83910AV/63, while no additional pin-compatible component is documented by the cited TI support discussion.
