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.
DP83924BVCE - Quad 10 Mb/s Ethernet PHY | Texas Instruments
The Texas Instruments DP83924BVCE is a quad-port 10 Mb/s Ethernet physical-layer transceiver integrated circuit with a 4.75 V to 5.25 V supply range in a 100-PQFP package. It combines four twisted-pair PHY channels and a programmable MAC interface supporting most standard seven-signal MAC interfaces, providing a consolidated physical-layer solution for multiport Ethernet equipment. An Ethernet physical layer, or PHY, is the interface between a Media Access Controller and physical network media. A PHY converts digital frames and control signals into electrical signaling suitable for a physical layer, while receiving and decoding incoming signals. Within the Ethernet hierarchy, the DP83924BVCE is an Ethernet interface IC, a physical-layer transceiver, a network-interface semiconductor, and ultimately a power-management-dependent mixed-signal component. The device provides four 10 Mb/s Ethernet ports, on-chip transmit-output filters, and a common four-port twisted-pair transceiver structure. Its 4.75 V minimum and 5.25 V maximum operating supply span supports conventional 5 V equipment designs. According to the manufacturer datasheet, the programmable MAC interface supports most standard seven-signal MAC interfaces, reducing the need for separate physical-layer devices when four network ports share one controller. The DP83924B architecture organizes the four PHY channels behind a configurable interface to a MAC or repeating-device controller. This multiport arrangement is intended to simplify board-level networking designs while preserving separate twisted-pair channels for each port. Because the available verified material does not enumerate every internal filter, equalization, timing, or link-detection parameter, those values should be taken directly from the current manufacturer datasheet before final signal-integrity or network compliance sign-off. Typical uses include four-port hubs and repeaters, concentrators, printed-circuit-board Ethernet switches, industrial network interfaces, test equipment, and legacy 10 Mb/s terminal systems. In each case, the quad-port organization is valuable when a controller has enough I/O capacity to service four separate MAC channels and the PCB can accommodate the associated magnetics or twisted-pair network connections. Designers should pay close attention to 5 V supply decoupling, the 100-pin quad-flat-package footprint, trace routing around each PHY channel, and the external magnetic components required by the implemented network topology. The available data identifies tube packaging and a commercial temperature grade, but it does not provide complete verified dimensions, pin names, absolute maximum ratings, or electrical test conditions. This page combines the verified distributor and manufacturer-linked specifications with practical integration guidance, package details, application context, pricing caveats, and drop-in replacement analysis. It also distinguishes verified facts from unavailable technical data so procurement and engineering teams can identify the exact information that still requires confirmation from the authoritative DP83924B datasheet.
DP8392CN-1 - IEEE 802.3 Coaxial Transceiver | Texas Instruments
The Texas Instruments DP8392CN-1 is an IEEE 802.3 coaxial transceiver interface with 16 through-hole DIP terminals, a nominal -9 V supply, and a commercial operating-temperature grade of 0°C to 70°C. It is designed to connect a coaxial Ethernet physical-layer cable to data-terminal equipment through transmit and receive signal paths. The verified listing identifies the device as a CTI, or Coaxial Transceiver Interface, and classifies it as an Ethernet transceiver rather than a general-purpose transceiver. Its legacy application is Thin Ethernet, or 10BASE-2, where the transceiver connects a station or network node to a coaxial bus. A coaxial transceiver interface is an interface IC that integrates the electrical functions needed to communicate over a shielded coaxial cable. In the broader networking hierarchy, it belongs to the network-interface and communications-semiconductor categories, where a physical-layer transceiver works alongside a network controller or system data bus. The DP8392CN-1 is therefore most useful when maintaining, repairing, or reproducing a legacy 10BASE-2 Ethernet design rather than designing a new modern Ethernet system. Its 16-DIP package favors through-hole construction and serviceable legacy equipment. Key verified attributes include the 16-terminal rectangular DIP package, through-hole terminal form, nominal -9 V negative supply, commercial temperature grade, and a listed 19.305 mm length. The device is identified as suitable for Ethernet transceiver applications and supports the coaxial cable line-driver and receiver function. The verified data does not provide output impedance, propagation delay, receiver sensitivity, isolation voltage, or detailed timing values, so those parameters should not be inferred from the product family without an applicable manufacturer document. Typical applications include legacy Thin Ethernet terminal adapters, coaxial network-interface cards, industrial or communications equipment retaining a 10BASE-2 port, and repair or restoration of older Ethernet hardware. The -9 V supply requirement must be checked against the surrounding circuit; it is not a modern 3.3 V or 5 V plug-in-compatible rail. The 16-pin through-hole footprint also requires mechanical and pin-level verification before replacement. The most important design consideration is that a coaxial transceiver is not interchangeable with every Ethernet transceiver having the same network function. Confirm the exact pinout, supply polarity, cable termination, connector type, and signal-level requirements in the applicable datasheet before layout or schematic changes. For new designs, verify that the legacy 10BASE-2 requirement is intentional; modern 10/100/1000 Ethernet generally uses different physical-layer devices. This page combines the verified distributor and manufacturer-source identification with package, application, and sourcing context. It distinguishes confirmed DP8392CN-1 facts from parameters that remain unavailable, rather than filling gaps with assumptions or unsupported substitutions.
DP8392CV-1 - Coaxial Transceiver Interface (CTI) | Texas Instruments
The Texas Instruments DP8392CV-1 is a Coaxial Transceiver Interface (CTI) for IEEE 802.3 Ethernet networks, integrating a 10BASE2/10BASE5 coaxial line driver and receiver with collision detection and a built-in jabber timer in a 28-pin PLCC (V28A) surface-mount package. The device operates as part of the classic DP8390/DP8391/DP8392 chipset, providing the physical-layer interface between a DTE and a coaxial cable segment with on-chip transmit/receive switching and heart-beat generation. A Coaxial Transceiver Interface (CTI) is a type of network transceiver IC that connects a Medium Access Controller (MAC) to a coaxial Ethernet bus, performing electrical line driving, signal recovery, collision detection (signal-quality error pulse generation), and jabber fault isolation. CTIs are a subset of physical-layer (PHY) transceivers that sit between the MAC block and the cable medium, and are descendants of early 10 Mb/s Ethernet silicon that pre-dated modern twisted-pair PHYs in the OSI model's physical layer of the network stack. Key features of the DP8392CV-1 include a 10 Mb/s Manchester-encoded data rate, a single +5 V supply operation, integrated transmit/receive path switching, integrated SQE (Signal Quality Error) test pulse generation, a built-in jabber timer with automatic transmitter disable after the maximum packet time, and a TTL/CMOS-compatible interface to the DP8390 NIC and DP8391 encoder/decoder devices. The 28-PLCC pinout uses J-bend surface-mount leads and is organized for direct cable-side and digital-side pin groups to simplify PCB layout. The architecture uses a bipolar driver for the coaxial interface with separate transmit and receive amplifiers, a 10 MHz fundamental oscillator with external clock-reference support, and an analog collision-detection comparator that produces the standard heart-beat pulse during inter-packet gaps. The on-chip jabber latch disables the transmitter if a continuous transmit exceeds the packet-time threshold, protecting the coax segment from stuck-node faults. Commercial-grade temperature range (0C to +70C) targets office and lab Ethernet environments. Typical applications include 10BASE2 (Thin Ethernet / Cheapernet) network interface cards, 10BASE5 (Thick Ethernet) AUI-to-coax converter adapters, legacy industrial Ethernet backbones on coax, and embedded systems that require an IEEE 802.3 coax link to communicate with vintage networking equipment or to bridge older industrial fieldbus hardware. The part also sees use in test equipment that emulates a coax segment endpoint. When designing with this device, observe AC termination and DC bias requirements specified in the datasheet typical application - a 1:1 pulse transformer on the Tx/Rx line and external pull-up/pull-down resistors on collision and receive-data lines. Decoupling should keep the +5 V supply near the analog VCC pins with both bulk and 0.1 uF ceramic capacitors to prevent noise from coupling into the receive path. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
DP83932BVF-25 - Ethernet Controller | Texas Instruments
Texas Instruments DP83932BVF-25 is an Ethernet controller with an IEEE 802.3 network interface, a 4.75 V to 5.25 V supply range, and a 132-pin PQFP package measuring 24.13 mm by 24.13 mm. The -25 suffix identifies a specific ordering variant within the DP83932 family, while BVF identifies the surface-mount quad flat package. This controller is intended for scalable LAN-node equipment requiring integrated Ethernet connectivity and a conventional parallel host interface. An Ethernet controller is a network interface controller that manages communication between a host processor and a physical Ethernet network. In the product hierarchy, it is an Ethernet interface IC, a peripheral interface controller, and a semiconductor designed for networking equipment. The DP83932BVF-25 belongs to the Texas Instruments SONIC family of Ethernet controllers, a product line historically developed for scalable and flexible LAN node designs. The verified data identifies the device as an IEEE 802.3 Ethernet controller supplied from 4.75 V to 5.25 V. One third-party technical listing reports a 100 mA supply current, while the DigiKey listing confirms the 132-PQFP package and commercial availability channel. These characteristics place the device in legacy and industrial networking designs where a 5 V Ethernet controller, parallel system interface, and exposed-lead quad flat package are practical. The BVF package uses 132 gull-wing terminals around a square body. Its relatively high pin count supports separate addressing, data, control, clock, interrupt, and network-side signals. Because the verified material does not provide a complete manufacturer pin table, individual terminal assignments cannot be transcribed safely. Engineers should use the manufacturer datasheet before PCB routing, particularly for supply, ground, reset, reference-clock, and signal-integrity connections. Typical uses include embedded industrial Ethernet nodes, print servers, automated test equipment, factory-control gateways, and legacy network-interface cards. In these systems, the controller provides the network-facing protocol and physical-interface control while the system processor handles higher-level services. A 4.75 V to 5.25 V operating supply allows integration with conventional 5 V logic systems, subject to the complete timing, electrical, and thermal limits in the datasheet. Designers should preserve the controller's required supply decoupling, provide a clean clock source, and route high-speed interface signals with controlled impedance and return paths. Because no verified price, detailed timing table, temperature range, clock requirement, or complete pin assignment was supplied, those values must be confirmed before schematic release. This page distinguishes verified facts from unavailable parameters rather than estimating them. This page combines verified distributor identification, family-level alternatives, practical Ethernet design guidance, and a parameter comparison framework that is not consolidated in a single distributor listing. It is intended to accelerate initial component selection while directing engineers back to the authoritative manufacturer documentation for final design decisions.
DP83932CVF-33 - 33MHz Ethernet Controller | Texas Instruments
Texas Instruments DP83932CVF-33 is a second-generation SONIC Ethernet network interface controller with a 5 V supply, a 32-bit or 16-bit system bus interface, and a 132-pin BQFP package. The controller is designed for high-speed 16-bit and 32-bit systems and uses DMA transfers that typically consume less than 3% of bus bandwidth at a 25 MHz bus clock. Selectable big-endian and little-endian byte ordering support integration across different host architectures. An Ethernet network interface controller is a semiconductor that manages data exchange between a host computer or embedded processor and an Ethernet network. The broader hierarchy is Ethernet controller → network interface controller → interface IC → integrated circuit. The SONIC architecture separates frame movement from the host processor, allowing Ethernet traffic to be transferred through DMA while the processor performs higher-level protocol processing. The DP83932CVF-33 provides a 5 V supply and supports both 32-bit and 16-bit host systems, as stated in the manufacturer datasheet. Its selectable bus byte ordering accommodates systems using either big-endian or little-endian conventions. The DMA interface is designed to limit bus utilization, with the datasheet stating that transfers typically consume less than 3% of bus bandwidth at 25 MHz. The controller is supplied in a 132-pin BQFP package identified as 24.13 mm by 24.13 mm in distributor data. Its exposed-lead package provides a large PCB footprint and external leads for system-bus, network-interface, timing, power, and control connections. The verified data identifies tray packaging and commercial-grade sourcing, while the exact operating-temperature limits and complete electrical timing tables were not included in the supplied excerpts. Typical uses include embedded Ethernet networking, industrial data acquisition, embedded logging, industrial controllers, computing modules, and firmware-boot or storage systems. The controller is appropriate where a host processor requires a dedicated Ethernet MAC with DMA-assisted transfers rather than handling every frame directly in processor software. When designing around the DP83932CVF-33, verify the complete 132-pin connection, network-interface circuit, oscillator requirements, reset behavior, and termination values against the manufacturer datasheet. PCB routing should keep high-speed bus and clock signals short, provide continuous ground-plane return paths, and include the decoupling network specified for the 5 V supply. This page combines verified distributor specifications, manufacturer-datasheet excerpts, sourcing information, structured drop-in family references, and practical integration guidance. It is designed to help engineers identify the correct controller package and evaluate DP83932CVF-33 for legacy Ethernet designs without obscuring which details remain to be confirmed from the full datasheet.
DP83934AVQB - 10BASE-T Ethernet Controller | Texas Instruments
Texas Instruments DP83934AVQB is a 10BASE-T systems-oriented Ethernet network interface controller with a parallel host interface and integrated twisted-pair PHY, supplied in a 160-pin PQFP package measuring 28 x 28 mm. It operates from a 4.75 V to 5.25 V supply and has a reported supply current of 140 mA. An Ethernet network interface controller, or NIC, is an interface IC that connects a host or embedded processor to a physical network. The DP83934AVQB belongs to the broader SONIC-T systems-oriented controller family. It combines network packet processing, physical-layer connectivity for 10BASE-T, and a parallel processor-facing interface in one component, reducing the need for separate Ethernet-interface logic in legacy embedded systems. The verified product information identifies a 10BASE-T PHY, a parallel interface, and twisted-pair connectivity as its principal features. Its 4.75 V to 5.25 V operating-supply range is compatible with conventional 5 V embedded logic, while the 160 mA-class supply requirement makes suitable regulator capacity and supply-noise control important. The 160-pin PQFP exposes substantially more interface and control signals than a small-scale network controller. The device is associated with the SONIC-T 25 MHz systems-oriented architecture. For a legacy network design, the controller handles Ethernet frame activity while the host accesses registers and buffers through its parallel interface. A complete implementation also requires suitable memory, clocking, isolation or magnetics, cable termination, and power-supply arrangements defined by the applicable system design. Typical applications include industrial embedded controllers, legacy 10BASE-T network adapters, test equipment, embedded communications modules, and control systems requiring a deterministic parallel host interface. Its primary advantage is integration: one large-scale controller provides both the systems-oriented network interface and 10BASE-T physical-layer function rather than requiring a separate PHY. Engineers should verify the exact 160-pin pinout, clock requirements, memory interface, magnetic-component recommendations, and PCB layout constraints against the manufacturer datasheet before release. The large PQFP also requires careful escape routing, and the 4.75 V to 5.25 V supply must remain within the specified range at every point in the design. This product page consolidates the verified manufacturer and distributor information, separates confirmed electrical and packaging facts from unavailable data, documents replacement constraints, and provides application-specific engineering guidance that is not available from a distributor listing alone.
DP83950BVQB - IEEE 802.3 Ethernet Repeater Controller | TI
The Texas Instruments DP83950BVQB is a Repeater Interface Controller (RIC) designed for IEEE 802.3 Ethernet multiport repeater systems. It operates from a 4.75 V to 5.25 V supply and is specified at 380 mA supply current, while the device is housed in a 160-pin QFP package measuring 28 mm by 28 mm. The controller provides the interface logic required to implement an IEEE 802.3 repeater unit, including repeater-segment partition and jabber functions described in the device documentation. A Repeater Interface Controller is an interface IC within the broader Ethernet networking and communications-controller category. In an Ethernet topology, a repeater receives and regenerates signals from one network segment onto another. The RIC coordinates the physical-layer attachment, collision handling, partition management, and system monitoring functions required by an IEEE 802.3 repeater implementation. The DP83950BVQB is therefore intended for designers building dedicated Ethernet hubs, concentrators, repeater cards, and other legacy 10BASE-T network equipment. The principal characteristics of the DP83950BVQB are its IEEE 802.3 repeater focus, 4.75 V to 5.25 V operating supply range, approximately 380 mA specified supply current, and 160-QFP package. The 160-pin package exposes the numerous repeater, port, control, and power-management connections needed for a multiport network repeater. Its size and pin count make it more appropriate for established repeater boards than compact embedded network nodes. The DP83950B family is associated with the National Semiconductor legacy product line that was subsequently represented under Texas Instruments. The device should be selected based on the original repeater architecture, electrical timing requirements, PCB footprint, and the availability of the associated Ethernet magnetics and physical-layer circuitry. The verified distributor information identifies the part as a specialized interface component rather than a general-purpose microcontroller. Typical applications include IEEE 802.3 repeater units, Ethernet hubs, network concentrators, multiport repeater cards, and legacy industrial or telecommunications Ethernet equipment. A design must provide the required 5 V supply, correct decoupling, Ethernet transformer or magnetics interfaces, and the appropriate transmission-line and signal-integrity implementation. The 160-QFP footprint requires careful fanout planning because the package has a high pin count and a large land pattern. Design considerations include verifying the complete pinout against the manufacturer datasheet, confirming the exact package variant, and checking the controller's system-level timing and reset requirements. The datasheet and distributor records should be used as the authority for pin functions, electrical limits, and repeater implementation details.

It provides a 2/2 transceiver arrangement, MAC-interface flexibility through MII, RMII, and RGMII, and diagnostic-tool support for automotive Ethernet designs. The device is supplied in a 6.00 mm × 6.00 mm, 36-pin VQFN package with wettable flanks. An automotive Ethernet PHY is a physical-layer interface integrated circuit that converts digital MAC data into signals suitable for a vehicle network and converts received cable signals back into digital data. It sits between an Ethernet MAC and the twisted-pair medium, providing the physical encoding, signaling, and diagnostic functions required for reliable in-vehicle communication. The DP83TC811R-Q1 family supports MII, RMII, and RGMII MAC interfaces through xMII flexibility. Its IEEE 802.3bw compliance targets 100BASE-T1 automotive Ethernet applications, where low-speed single-pair links are used to reduce wiring complexity while supporting vehicle data and control networks. The manufacturer also describes an integrated Diagnostic Tool Kit and a PRBS frame-generation tool compatible with internal loopbacks for transmit and receive testing without a MAC. The package uses a wettable-flank VQFN construction, which supports inspection of solder joints in automotive electronics assemblies. Its 36-pin package and 6 mm × 6 mm footprint are intended for surface-mount designs. Exact operating voltage, current, timing, temperature, pin names, isolation, and qualification values must be confirmed from the manufacturer datasheet before schematic release or PCB layout approval. Typical design uses include automotive Ethernet gateways, vehicle domain controllers, infotainment systems, telematics units, body controllers, sensor interfaces, and diagnostic test equipment. The MAC-side interface is selected according to the host controller requirements, while the cable-side network is designed according to the applicable 100BASE-T1 wiring and automotive Ethernet implementation constraints. The flexible MAC interface helps reduce platform duplication across different host-controller configurations. A key design consideration is validating the complete interface chain, including MAC timing, cable termination, common-mode components, isolation strategy, connector selection, and automotive EMC requirements. This page combines verified manufacturer and distributor information with explicit data gaps; it does not infer electrical specifications that are absent from the supplied source data. Engineers should use the official DP83TC811R-Q1 datasheet and product page for final component selection and implementation.

The Texas Instruments DP83TC812SRHARQ1 is an AEC-Q100 qualified, TC-10 compliant 100BASE-T1 automotive Ethernet PHY transceiver housed in a 36-pin VQFN (RHA) 6x6 mm package with RGMII and SGMII MAC interfaces. The device delivers 100 Mbps over a single twisted pair using proprietary 100BASE-T1 IEEE 802.3bw physical layer technology, supporting full-duplex and half-duplex operation in harsh automotive environments. An automotive Ethernet PHY is a physical layer transceiver that converts digital MAC data into differential pulse-shaped signals transmitted across an unshielded single twisted-pair (UTP) cable, while simultaneously decoding received signals back into digital data. The DP83TC812S-Q1 family sits within the broader in-vehicle networking hierarchy: PHY -> transceiver -> Ethernet switch -> ECU/gateway -> automotive zonal architecture, replacing legacy CAN, FlexRay, and LIN buses in ADAS, infotainment, and chassis domains. Key features of the DP83TC812SRHARQ1 include integrated TC-10 wake/sleep state machine for power-managed automotive networks, low-power sleep current below the TC-10 specification, RGMII and SGMII MAC interface options for flexible SoC connectivity, and on-chip diagnostics including cable diagnostics, signal quality indicator, and IEEE 1588 SFD timestamping. The 36-VQFN package with exposed thermal pad provides a robust thermally efficient surface-mount footprint qualified to AEC-Q100 Grade 1 (-40C to +125C). Architecturally, the DP83TC812SRHARQ1 uses a DSP-based echo-cancelling receiver with adaptive equalization to support automotive cable lengths up to 15 m of UTP. Internal LDOs generate analog and digital rails from a single 1.8V or 3.3V supply, while the MAC interface, MDI, and management (MDIO/MDC) signals operate from a separate I/O domain, simplifying multi-voltage SoC integration. Typical applications include automotive advanced driver assistance systems (ADAS) camera and radar links, in-vehicle infotainment (IVI) backbones, body and chassis domain controllers, zonal Ethernet gateways, and ECU-to-ECU bridged networks. The TC-10 compliance enables partial networking where unused PHYs can sleep while the rest of the network remains active, reducing vehicle quiescent current. When designing with the DP83TC812SRHARQ1, ensure the MDI differential pair is routed as a 100-ohm differential transmission line with ground-referenced return path and that the supply decoupling network follows the TI reference layout. The device supports both RGMII (1.8V/2.5V/3.3V) and SGMII, allowing pin-compatible upgrades from older 100BASE-TX designs with the same 36-VQFN footprint.

DP83TC814R-Q1 - 100BASE-T1 Auto Ethernet PHY | TI
The Texas Instruments DP83TC814R-Q1 is a low-power 100BASE-T1 automotive Ethernet physical layer (PHY) transceiver, IEEE 802.3bw compliant and AEC-Q100 qualified, housed in a 36-pin VQFN package measuring 6.00 mm x 6.00 mm with wettable-flank leads. The R-suffix version omits TC10 sleep/wake support, differentiating it from the DP83TC814S-Q1 variant. An Ethernet PHY (physical layer device) is the interface IC that converts digital MAC frames into signals transmitted over a physical medium. In the Ethernet IC hierarchy - PHY transceiver -> Ethernet controller -> network interface -> automotive E/E architecture - the PHY is the final analog stage that determines link robustness, power draw, and EMC behavior. 100BASE-T1 (formerly BroadR-Reach) transmits 100 Mbps full-duplex over a single unshielded twisted pair, halving cabling weight versus conventional 100BASE-TX. Key features include a flexible MAC interface whose I/O supply (VDDMAC) is configurable to 1.8 V, 2.5 V, or 3.3 V, easing direct connection to a wide range of automotive microcontrollers without level shifters. The device supports full and half duplex operation with RMII media access, integrates TI's diagnostic tool kit for real-time link monitoring, and delivers low-power modes essential for network-managed ECU sleep strategies. According to the DP83TC814x-Q1 datasheet, the die family shares a common footprint strategy across speed grades. A major engineering benefit is footprint unification: the device is pin-2-pin compatible with the DP83TG720 (1000BASE-T1) and form-factor compatible with DP83TC811 and DP83TC812, so a single PCB layout can be reused across DP83TC811, DP83TC812, DP83TC814, and DP83TG720 designs. This lets automotive Tier-1s qualify one board platform for 100 Mbps and 1 Gbps in-vehicle networking variants. Typical applications include camera and sensor data links in ADAS systems, gateway ECUs bridging CAN and Ethernet domains, infotainment backbone nodes, and domain/zonal controller interconnects in modern vehicle networks. When designing with this part, follow TI's reference design guidance for the single-pair MDI termination and magnetics network, and verify EMC performance on the target harness, since automotive 100BASE-T1 compliance depends heavily on layout and common-mode treatment. This page adds value beyond the datasheet by synthesizing distributor availability, drop-in alternatives, and practical design notes in one place. Pricing shown is as of 2026-10-19.
DP83TC815-Q1 - 100Base-T1 Automotive Ethernet PHY | Texas Instruments
The Texas Instruments DP83TC815-Q1 is an IEEE 802.3bw and Open Alliance (OA) compliant automotive-qualified 100Base-T1 Ethernet physical layer transceiver delivering full PHY functionality over a single unshielded or shielded twisted pair, housed in a 36-pin VQFN (6x6 mm) package. The device supports RGMII, SGMII, and xMII interface flexibility with hardware time-stamping per IEEE 802.1AS / IEEE 1588v2. It targets 100 Mbps automotive Ethernet networks requiring precise time synchronization. An automotive Ethernet PHY (Physical Layer transceiver) is an interface IC that converts digital MAC-side data into differentially-encoded signaling for transmission over copper twisted-pair cabling. Within the OSI model, it occupies Layer 1, sitting between the MAC controller (or switch) and the physical medium. The 100Base-T1 (IEEE 802.3bw) variant uses full-duplex transmission over a single twisted pair with PAM-3 / binary encoding and EMC-friendly spectral shaping, replacing legacy CAN and FlexRay backbones in zonal automotive architectures. The DP83TC815-Q1 belongs to the broader category of automotive PHYs that bridge Ethernet PHYs -> wireline transceivers -> interface ICs -> integrated circuits. Key features include compliance with IEEE 802.3bw 100Base-T1 and the OPEN Alliance TC-1/TC-10 specifications, integrated IEEE 802.1AS / IEEE 1588v2 hardware time-stamping for sub-microsecond synchronization across ADAS sensors, OA TC-10 low-power sleep with wake forwarding, and AEC-Q100 qualification for automotive temperature grades. The single twisted-pair interface dramatically reduces wiring harness weight versus traditional 100Base-TX (which requires two pairs). The architecture combines an analog front-end with DSP-based echo and crosstalk cancellation, a precision PLL, and a digital interface controller. Hardware time-stamping on both transmit and receive paths ensures deterministic latency for time-sensitive applications such as radar sensor fusion, deterministic Ethernet, and synchronized distributed camera networks. Typical applications include automotive ADAS sensor Ethernet links, body and zonal ECU networking, rear-view and surround-view camera systems, in-vehicle infotainment backbones, and industrial 100Base-T1 links requiring the same precision timing. Designers select this part when they need an automotive-grade 100 Mbps single-pair Ethernet PHY with hardware time-stamping and the OPEN Alliance TC-10 sleep/wake feature for power-constrained modules. When designing with this device, ensure the MDI network matches the OPEN Alliance TC-1 channel specification and place the 1:1 termination and common-mode choke close to the MDI pins. The TC-10 sleep entry/exit sequence requires careful MAC-side coordination to honor wake-forward timing budgets; this part is intended as a drop-in PHY replacement for other TI 36-pin VQFN 100Base-T1 designs. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, including TSN configuration guidance, xMII selection trade-offs, and OPEN Alliance TC-10 power-state sequencing.

The Texas Instruments DP83TG720RWRHATQ1 is an IEEE 802.3bp and Open Alliance compliant automotive Ethernet physical layer transceiver (PHY) that provides all physical layer functions needed to transmit and receive data over unshielded or shielded single twisted-pair cables, supporting 1000BASE-T1 in a 36-pin VQFN (6x6) package. It operates from a 1.8V/2.5V/3.3V supply, integrates an RGMII MAC interface, and is AEC-Q100 qualified for automotive grade 1 environments. The device supports both full-duplex and half-duplex operation over a single twisted pair, delivering Gigabit-class Ethernet in automotive zonal architectures. What is an automotive Ethernet PHY? An automotive Ethernet PHY is a physical layer transceiver that converts digital MAC-layer data into analog signals suitable for transmission over copper cabling inside a vehicle. It sits between the Media Access Controller (MAC) and the MDI connector, encoding/decoding bits and handling line-side equalization, echo cancellation, and link training. As part of the broader Ethernet PHY category (Ethernet PHY -> transceiver -> interface IC -> semiconductor), automotive Ethernet PHYs follow IEEE 802.3bp (1000BASE-T1) and Open Alliance specifications designed for electromagnetic compatibility and single-pair robustness inside vehicles. Key features of the DP83TG720RWRHATQ1 include 1000 Mbps line-side throughput, RGMII host interface, integrated 100BASE-T1 legacy support via front-pin compatibility with TI's lower-speed PHY family, Open Alliance interop compliance, and operation from -40C to +125C. The device provides MAC-side loopback, diagnostic PRBS patterns, and cable diagnostics to support field troubleshooting. The 6x6 mm VQFN-36 package with exposed pad supports single-sided PCB routing for compact automotive modules. The DP83TG720 uses DSP-based adaptive equalization and echo cancellation tuned for the harsh automotive environment (PVT variation, motors, ignition noise). The PHY manages wake/sleep signaling for Partial Networking and operates from a 1.8V digital core with separate analog supplies for isolation from noise on the MDI line. Front-pin compatibility with the 100BASE-T1 DP83TG720S-Q1 enables one PCB layout to support both 100 Mb and 1 Gb automotive Ethernet. Typical applications include advanced driver-assistance systems (ADAS) sensor fusion, in-vehicle networking gateways, surround-view and 4D radar data aggregation, automotive zonal ECUs, and telematics/central compute modules. The 1000BASE-T1 link removes the need for legacy automotive buses (CAN, FlexRay) where high bandwidth is required. When designing with this PHY, ensure proper MDI line protection and common-mode chokes are used per application note SNLA244, and follow the DP83TG720 reference schematic for the 1.8V supply decoupling arrangement.

DS10BR150TSD/NOPB - 1.0 Gbps LVDS Buffer/Repeater | TI
The Texas Instruments DS10BR150TSD/NOPB is a single-channel 1.0 Gbps LVDS buffer/repeater optimized for high-speed signal transmission over lossy FR-4 printed circuit board backplanes and balanced cables. Housed in an 8-pin WSON (NGQ) 3x3 mm package, it features fully differential signal paths that ensure exceptional signal integrity and noise immunity, with 39 ps typical propagation delay and 21 mA supply current. An LVDS (Low-Voltage Differential Signaling) buffer/repeater is a signal-conditioning interface IC that regenerates a high-speed differential data path whose amplitude and edge rate have been degraded by PCB trace loss, connector crosstalk, or cable attenuation. The DS10BR150 belongs to the LVDS interface category, within the broader interface IC and high-speed signal-conditioning hierarchy used in networking, telecom, and backplane data links where 100 Ω differential impedance and low jitter are mandatory. Key features include a wide input common-mode voltage allowing acceptance of LVDS, CML, and LVPECL input levels with LVDS-compliant output levels. The device operates from a single 3.3 V supply, supports data rates from DC up to 1.0 Gbps, and provides a power-down pin for standby current reduction. Industrial temperature range of -40°C to +85°C and a low-jitter design make it suited for serial-data distribution in systems where eye-margin preservation across long trace runs is critical. The DS10BR150 uses a fully differential current-mode architecture with internal termination and adjustable receiver equalization, providing a typical propagation delay of 39 ps and ultra-low pulse-skew-generate of 7 ps. The low-jitter characteristic preserves transmit eye-mask compliance across FR-4 backplanes with insertion loss that would otherwise close the eye at GbE and FibreChannel link speeds. Integrated fail-safe biasing ensures a deterministic output when the input is open, shorted, or undriven. Typical applications include FR-4 backplane repeater links between line cards and switch fabrics in networking switches and routers, clock and data distribution in telecom equipment, LVDS extension in test-and-measurement instrumentation, and SATA / FibreChannel signal fan-out in storage area network (SAN) cards. The wide input common-mode range also makes it useful for level-translation between CML/LVPECL drivers and LVDS receivers on mixed-logic boards. When designing with this device, place 100 nF decoupling capacitors as close as possible to the VCC pin and use a continuous ground reference under the WSON exposed pad (EP) to control thermal resistance and provide a low-impedance return path. Maintain 100 Ω differential impedance on input and output traces, route TX/RX pairs length-matched within 5 mil, and avoid right-angle bends to preserve the 1 Gbps eye.

DS10BR254TSQ/NOPB - 1.5Gbps 1:4 LVDS Repeater | TI
The Texas Instruments DS10BR254TSQ/NOPB is a 1.5 Gbps 1:4 LVDS repeater with a 2:1 multiplexed input stage, a 440 ps propagation delay and 135 mA supply current, housed in a 40-pin WQFN (RTA) 6x6 mm package with exposed pad. The /NOPB suffix denotes a no-Pb, RoHS-compliant manufacturing flow. An LVDS (Low-Voltage Differential Signaling) repeater, also called a buffer or fanout buffer, is an interface IC that regenerates high-speed differential signals to restore signal integrity over lossy media. In the signal-chain hierarchy it sits between a driver (SoC, FPGA, ASIC) and multiple receivers, extending reach across FR-4 backplanes and balanced-impedance cables while isolating loads that would otherwise degrade edge rates. Key features include a 1.5 Gbps maximum data rate per LVDS channel, a 2-input multiplexer with an external select pin that supports redundant-path or source-switching architectures, four identical fanout outputs that regenerate each input pair with full LVDS swing, and a loss-of-signal (LOS) detection circuit. Fully differential signal paths deliver exceptional noise immunity, while the compact WQFN-40 package with thermal pad enables dense backplane card designs. Architecturally, the device contains two differential input pairs, a low-skew mux, and four parallel low-jitter output drivers. Propagation delay of 440 ps and matched internal channel lengths keep output-to-output skew tight for clock and data distribution. The 1.7 pF input capacitance minimizes loading on the source, and the 3.0 V nominal supply (3.0 V to 3.6 V range) suits standard 3.3 V rails. Typical applications include FR-4 backplane clock and data distribution, redundant bus multiplexing in telecom and networking line cards, high-speed signal fanout from FPGAs or ASICs in test and measurement instrumentation, and long-reach LVDS links over balanced cables. Design consideration: maintain 100-ohm controlled-differential impedance on all LVDS traces, keep the mux select pin stable during operation, and leverage the LOS output for fault reporting in redundant architectures. The exposed pad must be soldered to a grounded copper pour for thermal and return-path performance.

DS15BR400TVS/NOPB - 4-Ch LVDS Buffer 2Gbps TQFP-48 | Texas Instruments
The Texas Instruments DS15BR400TVS/NOPB is a 4-channel LVDS buffer/repeater (ReDriver) supporting data rates up to 2 Gbps per channel, operating from a 3.0 V to 3.6 V supply with a typical supply current of 215 mA, housed in a 48-pin TQFP (PFB) package measuring 7 x 7 mm. An LVDS buffer/repeater is a signal-conditioning interface IC that sits in the middle of a high-speed differential data path. It receives degraded low-voltage differential signaling (LVDS) or Bus LVDS waveforms, regenerates clean logic levels, and re-transmits them, restoring signal integrity over lossy media. In the system hierarchy, it belongs to the signal buffer/repeater class of interface ICs, bridging serializers, deserializers, and backplanes in high-speed digital systems. Key differentiating features include pre-emphasis that overcomes intersymbol interference (ISI) jitter effects from lossy backplanes and cables, a flow-through pinout that simplifies board layout and minimizes internal device jitter, and compatibility with LVDS and Bus LVDS signal levels such as those used by TI 10-, 16-, and 18-bit serializers and deserializers (SerDes). Architecturally, the DS15BR400 uses high-speed differential input buffers followed by output drivers with selectable pre-emphasis, keeping the internal data path short and symmetric. This low-jitter design preserves eye opening at 2 Gbps, which is critical for bit-error-rate targets in multi-gigabit links. The NOPB suffix denotes a lead-free, RoHS-compliant finish. Typical applications include rack-card backplane interconnects, point-to-point cable driver and receiver links, chassis-to-chassis high-speed data distribution, and buffering of SerDes links in industrial, medical imaging, and telecom equipment where signals must traverse long lossy traces or cables. A key design consideration: pre-emphasis increases output swing and therefore power dissipation, so apply only the level needed for the channel loss; excessive pre-emphasis can degrade signal margin at the far end. Verify supply decoupling with low-ESR ceramics close to each VCC pin. This page synthesizes verified distributor data, drop-in alternative analysis, pricing tiers, and practical engineering design notes not found in the manufacturer datasheet.
DS160PR410RNQR - 4-Ch PCIe Gen-4 Linear Redriver | Texas Instruments
The Texas Instruments DS160PR410RNQR is a quad-channel low-power, high-performance linear repeater/redriver designed to support PCI Express (PCIe) Generation 1.0, 2.0, 3.0 and 4.0 in a 40-pin WQFN (RNQ) 6x4 mm package with exposed thermal pad. The device operates up to 16 Gbps per lane for PCIe 4.0 and up to 25 Gbps for protocol-agnostic interfaces including Ultra Path Interface (UPI) 2.0. A redriver is a signal-conditioning device that sits between a transmitter and receiver on a high-speed serial link to compensate for channel loss. It uses continuous-time linear equalizers (CTLE) to apply frequency-dependent gain that restores the high-frequency components attenuated by the PCB trace, connector, and cable. The DS160PR410's CTLE boosts up to 18 dB at 8 GHz, which extends channel reach beyond what a passive link budget would normally allow. The device also includes automatic receiver detection tailored to PCIe use cases, allowing seamless insertion on a powered link. Key features of the DS160PR410RNQR include CTLE boost up to 18 dB at 8 GHz, automatic receiver detection for PCIe, integrated termination, individual channel enable/disable via I2C or pin strap, low latency suitable for forward and reverse direction signaling, and 3.3 V single-supply operation. The device is protocol agnostic, meaning it can be repurposed for any AC-coupled, NRZ differential interface up to 25 Gbps without protocol-specific state machines. The architecture uses a linear equalizer at each input followed by a limiting or linear output driver. Unlike retimers, redrivers do not require clock-data recovery (CDR) and do not add protocol latency, making them ideal for PCIe-compliant systems where every nanosecond of added latency must be accounted for in link training. The DS160PR410 supports both linear and limiting modes, giving designers flexibility between preserving multi-level eye characteristics or maximizing output swing. Typical applications include server and workstation motherboards, NVMe SSD riser cards, backplanes, and riser cards that need to recover PCIe signal integrity across long trace routes or through connectors. Industrial and embedded computing platforms with PCIe over cable also benefit. Because the device is protocol agnostic, it can be used for UPI 2.0, SATA, SAS, and other AC-coupled NRZ interfaces up to 25 Gbps. When designing with the DS160PR410RNQR, AC-coupling capacitors must be placed on the upstream transmit side of each redriver channel. The device supports SMBus/I2C control for fine-grained CTLE adjustment, or pin-strap configuration for simple deployment. Layout should keep high-speed differential traces length-matched within the channel and use 85 ohm differential impedance. Refer to the manufacturer datasheet for full register map and recommended PCB footprint. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone.
DS160PR410RNQT - 4-Ch PCIe Gen-4 Linear Redriver, 25 Gbps, 40-WQFN | TI
The Texas Instruments DS160PR410RNQT is a four-channel, low-power, high-performance linear repeater/redriver designed to support PCI Express (PCIe) Generation 1.0, 2.0, 3.0, and 4.0, with protocol-agnostic operation up to 25 Gbps including Ultra Path Interface (UPI) 2.0 and DisplayPort. The part is housed in a 40-pin WQFN (RNQ) 6x4 mm package and integrates four CTLE-equipped receivers that can boost high-frequency loss by up to 18 dB at 8 GHz. A linear redriver (also called a linear repeater or signal conditioner) is a protocol-agnostic high-speed interface IC placed between a transmitter and a receiver to restore signal amplitude and edge rate after channel loss. It sits in the signal-path hierarchy between the physical medium (PCB traces, connectors, cables) and the PHY/SerDes, complementing retimers (which include a CDR and re-clock) by offering lower latency and lower power at the cost of no jitter cleaning. Key features include automatic receiver detection for PCIe use cases, programmable CTLE equalization up to 18 dB at 8 GHz to extend channel reach, integrated termination, low additive jitter, and per-channel equalizer adjustment through pin-strap or SMBus/I2C control. The device supports AC-coupled transmitter common-mode voltage, low stand-by current, and an operating temperature range of -40 C to +85 C. The DS160PR410 uses a continuous-time linear equalizer architecture on each receive path to compensate for frequency-dependent loss from FR4 PCB traces, long cables, and connector crosstalk. Because the redriver is linear (not a retimer), the part adds minimal latency (typically <100 ps per channel) and preserves TX de-emphasis / RX CTLE training handshakes, allowing seamless insertion in PCIe link training without protocol glue logic. Typical applications include server and workstation motherboards (CPU-to-PCIe slot signal conditioning), PCIe riser cards, external PCIe enclosures, storage controllers (NVMe SSD backplanes), accelerator cards (GPU/AI PCIe Gen-4 add-in cards), and embedded platforms that need loss compensation across long PCB routes or backplanes. When laying out a board, place the redriver as close as possible to the lossy element (connector or long trace) and provide a continuous reference-plane ground beneath the WQFN-40 exposed pad for both thermal dissipation and return-path integrity. Decouple each VCC pin with a 0.1 uF X7R cap and a 4.7 uF bulk capacitor to keep the internal CTLE bias network stable.
DS2482S-800+T&R - 8-Channel 1-Wire Master | Maxim Integrated
The Maxim Integrated DS2482S-800+T&R is an 8-channel I2C-to-1-Wire bridge device that interfaces directly to standard (100 kHz max) or fast (400 kHz max) I2C masters to perform bi-directional protocol conversion between the I2C master and any downstream 1-Wire slave devices, housed in a 16-pin SO (SOIC-Narrow-16) package supplied on a 2,500-piece tape-and-reel. An I2C-to-1-Wire bridge is a specialized protocol converter IC that sits between a microcontroller's I2C bus and one or more 1-Wire slave peripherals (such as DS18B20 temperature sensors, DS2401 serial numbers, or iButtons). It offloads the strict 1-Wire timing requirements - including the reset/presence pulse sequence, byte-level time slots, and strong pull-up timing - from the host MCU, allowing the host to communicate with 1-Wire devices through simple I2C register reads and writes. The DS2482S-800 variant specifically integrates eight independent 1-Wire I/O channels, enabling a single bridge to manage up to eight separate 1-Wire buses, which is critical in systems that need isolated sensor networks. Key features include an operating supply voltage of 2.9 V to 5.5 V, internal factory-trimmed timers that relieve the host processor of timing-critical tasks, three binary address inputs that resolve I2C slave-address conflicts, and built-in weak pull-ups to support 1-Wire parasitic-power devices. The device is rated for an operating temperature range of -40 C to +85 C, making it suitable for industrial environments. The DS2482S-800 uses an I2C slave interface with selectable addresses (0x18-0x1F) and exposes each 1-Wire channel through independent IO pins (IO0-IO7). An internal active pull-up handles the strong pull-up required for parasite-powered 1-Wire devices during temperature conversion or EEPROM writes, while per-channel slew-rate control and software-controlled 1-Wire timing parameters ensure signal integrity across varying bus lengths. Typical applications include multi-channel DS18B20 temperature monitoring in HVAC, server farm, and industrial-process-control systems; building-automation sensor networks; and any embedded design that needs to read multiple 1-Wire devices without dedicating a full GPIO port to bit-banging the 1-Wire protocol. When designing with this device, note that each 1-Wire channel needs a decoupling capacitor close to its IOx pin and a 4.7 kohm pull-up to VDD. Unused IOx pins may be left floating because internal pull-ups hold them high. The I2C address is set by the AD0/AD1/AD2 pins and must match the host firmware configuration. This page synthesizes distributor pricing, same-family alternatives, and practical design notes not found in the manufacturer datasheet.
DS2484Q+T - 1-Wire Master I2C Bridge 8-TDFN | Maxim Integrated
The Maxim Integrated DS2484Q+T is a single-channel 1-Wire® master device that performs I2C-to-1-Wire protocol conversion in an 8-pin TDFN (2 mm x 3 mm) package. It operates from 1.71 V to 5.25 V supply voltage and bridges standard (100 kHz max) or fast-mode (400 kHz max) I2C masters to downstream 1-Wire slave devices, presenting itself as the 1-Wire master to any attached slave. Internal user-adjustable timers relieve the host processor from generating time-critical 1-Wire waveforms such as reset, presence-detect, read/write time slots and strong pullup. What is a 1-Wire bridge? A 1-Wire bridge is a type of protocol conversion IC that maps a generic serial bus (here, I2C) to Maxim's proprietary 1-Wire single-wire half-duplex protocol used by devices such as iButtons, temperature sensors (DS18B20), battery monitors (DS2781), and EEPROMs (DS1990/DS2431). In the broader hierarchy, the DS2484 sits at: protocol bridge → interface IC → signal conditioning IC → integrated circuit, eliminating the software bit-banging overhead normally required of the host MCU while improving timing margins and 1-Wire signal integrity through active pullup drive. Key features include an integrated 1-Wire strong-pullup switch capable of delivering up to 20 mA to power parasite-powered 1-Wire slaves, ±5 kV HBM ESD protection on the 1-Wire I/O line, a hardware adjustable slew rate for the 1-Wire output, sleep-mode current of less than 1 µA, and an open-drain active-low OUT output that mirrors the 1-Wire line state to the host. The I2C address is fixed at 0x30 and is selectable via the AD0 pin for use of up to two devices on the same bus. At the architecture level the DS2484 pairs a finite-state-machine-driven 1-Wire master engine with an I2C slave controller and on-chip timing reference, allowing deterministic reset / presence / read / write command sequencing without host MCU overhead. The 2x3 TDFN with exposed pad keeps the RθJA low enough for hot environments, and a selectable CRC enable bit provides automatic CRC16 generation for the 1-Wire ROM command sequence. Typical applications include IoT sensor hubs and edge nodes driving multiple DS18B20 temperature sensors, multi-tenant access control with iButton DS1990 readers, asset-tracking reference designs using DS2431 serial number ICs, and secure-print-cartridge / medical-identification authentication with Crypto-iButton or SHA-1 secure slaves. Battery-powered coin-cell designs benefit from the device's sub-1 µA sleep current. When designing with this part, pay attention to the strong-pullup timing window after a Convert-T command; supplying a 4.7 kΩ external pull-up to a regulated rail rather than the 1-Wire line preserves the on-chip switch for energizing the slave in parasite-power mode.
