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.
DP83934CVUL-20 - 25MHz Ethernet NIC | Texas Instruments
Texas Instruments DP83934CVUL-20 is a 25 MHz SONIC-T systems-oriented network interface controller with a twisted-pair interface, packaged in a 160-pin PQFP. It operates from a 4.75 V to 5.25 V supply and is designed for 32-bit and 16-bit high-speed processor systems. The controller supports selectable 16-bit or 32-bit data paths, little-endian and big-endian bus operation, and integrated Ethernet framing, addressing, and packet handling. A network interface controller, or NIC, connects a processor or bus-based embedded system to an Ethernet network. The DP83934 belongs to the systems-oriented Ethernet controller family and combines a dedicated Ethernet data path with host-bus and twisted-pair connectivity. Its SONIC-T architecture separates network processing from the host bus, allowing demanding 32-bit systems to exchange packets without handling low-level Ethernet protocol work in the host processor. The principal operating characteristics include a 25 MHz controller clock, a selectable 16-bit or 32-bit host data path, and a 4.75 V to 5.25 V supply range. The 32-bit path doubles the parallel transfer width relative to the 16-bit option, while BMODE configuration supports little-endian systems and big-endian systems. The twisted-pair interface connects the controller to an Ethernet physical layer, and the manufacturer identifies the component as a systems-oriented network interface controller. The DP83934CVUL-20 is supplied in a 160-pin PQFP package and is packaged in a tube according to the distributor specification. Its comparatively high pin count provides dedicated parallel data, control, address, interrupt, and network-interface signals, reducing multiplexing and supporting a broad host-bus interface. The 140 mA supply-current specification describes the device's 5 V operating domain, while the 4.75 V to 5.25 V range provides conventional tolerance around a nominal 5 V rail. Typical applications include industrial Ethernet control equipment, embedded test systems, legacy 32-bit communications controllers, printed-circuit network interfaces, and embedded platforms that require a wide parallel host bus. The controller is especially relevant when an existing system already uses the SONIC-T interface and its associated software model. Modern designs with USB or compact embedded Ethernet links may instead favor newer interface architectures with smaller packages and lower host processing overhead. Board design should preserve the controller's synchronous bus timing, provide clean 5 V power, and route high-speed host and network signals with short, controlled paths. Differential Ethernet conductors should be routed as a pair with continuous reference planes, while reset, clock, and timing-critical signals require attention to datasheet timing constraints. Because this is a 160-pin PQFP device, fanout and escape routing demand a multilayer PCB and careful via planning around the fine-pitch package perimeter. This product record combines the manufacturer's controller description with package, interface, voltage, current, bus-width, and ordering information. It also provides drop-in replacement guidance, application-specific design considerations, and a parameter comparison intended to accelerate legacy Ethernet controller design, maintenance, and component-obsolescence reviews.
DP83934CVUL-25 - 25 MHz Ethernet Controller | Texas Instruments
Texas Instruments DP83934CVUL-25 is a 25 MHz SONIC-T systems-oriented Ethernet network interface controller with a parallel interface and twisted-pair interface, housed in a 160-pin PQFP package measuring 28 mm by 28 mm. Its specified operating supply range is 4.75 V to 5.25 V, its operating supply current is 140 mA, and its commercial temperature range is 0 °C to 70 °C. An Ethernet network interface controller is an interface IC that connects a digital system to an Ethernet physical layer. It manages network-frame processing and provides the parallel data path required by compatible system logic. The DP83934 family belongs to the wider networking hierarchy of Ethernet controller, network interface controller, interface IC, and semiconductor. The DP83934CVUL-25 is identified as a 10 Base-T PHY parallel-interface Ethernet controller. A 10Base-T implementation uses twisted-pair cabling and is suited to legacy 10 Mb/s Ethernet systems, embedded network equipment, network interface adapters, and industrial or commercial control systems that retain compatibility with an existing SONIC-T design. The parallel interface provides a direct connection route to compatible bus and buffer logic rather than relying on a serial transceiver. Key characteristics include a 25 MHz system-oriented design, a 160-PQFP package, and a 4.75 V to 5.25 V supply requirement. Its 140 mA operating supply current is a key design consideration when calculating total system power and thermal behavior. The commercial 0 °C to 70 °C range distinguishes this ordered variant from industrial- or extended-temperature versions. The DP83934 incorporates the functions required by a dedicated Ethernet controller, including network-interface control, frame handling, and twisted-pair connectivity. These functions allow a host processor or embedded controller to communicate through Ethernet while separating medium-access and frame-processing tasks from the system processor. This division can reduce host-side protocol overhead in equipment designed around the DP83934 family. PCB implementation requires careful attention to the 160-pin PQFP footprint, high-density escape routing, ground distribution, and signal integrity. The 28 mm by 28 mm package provides ample routing area compared with a compact QFP, but it still demands a disciplined power and return-path layout. Decoupling should be placed directly across the relevant supply pins, and unused inputs should be handled according to the manufacturer’s pin-description and application guidance. This page combines the documented device identity, electrical envelope, package information, lifecycle status, application guidance, and clearly identified family alternatives. It is intended to help engineers assess whether the obsolete DP83934CVUL-25 remains appropriate for legacy maintenance, original-equipment repair, or a controlled redesign rather than new high-volume networking development.
DP83934CVUL-33 - 33MHz 10Base-T Ethernet Controller | TI
The Texas Instruments DP83934CVUL-33 is a 33 MHz SONIC-T systems-oriented network interface controller with an integrated 10Base-T PHY, a parallel host interface, and a 160-pin PQFP package measuring 28 x 28 mm. It operates from a 4.75 V to 5.25 V supply and is identified as a commercial-grade component with an operating range of 0°C to 70°C. An Ethernet network interface controller, or NIC, connects a host processor to a physical network. The DP83934 belongs to the SONIC-T controller family and combines network packet handling with twisted-pair physical-layer connectivity. Its parallel interface makes it suitable for embedded systems and industrial equipment that use a processor bus rather than a serial Ethernet PHY arrangement. The integrated 10Base-T PHY reduces the number of external network-interface components required in a legacy 10 Mb/s design. The principal identifiable features of the DP83934CVUL-33 are its 33 MHz controller clock, 10Base-T network support, parallel interface, 4.75 V to 5.25 V supply range, and 140 mA supply current. The -33 suffix identifies the clock configuration, while CVUL identifies the commercial temperature grade and 160-pin PQFP configuration. The supplied 28 x 28 mm package offers adequate pin density for parallel bus, memory-interface, clock, reset, interrupt, and network-related connections. This controller is based on the SONIC-T systems-oriented architecture, an integrated design that places Ethernet packet processing and twisted-pair interface support in one device. Such integration can simplify board partitioning when an existing system already uses the SONIC register and DMA programming model. Direct replacement is nevertheless more dependent on software and board continuity than package similarity alone: register access, interrupt behavior, DMA behavior, and initialization sequences must be compatible with the host processor and existing firmware. Typical applications include legacy 10Base-T industrial controllers, embedded Ethernet gateways, print servers, terminal servers, set-top equipment, and embedded communication systems designed around a parallel host bus. The DP83934CVUL-33 is most appropriate when an existing platform depends on the SONIC-T programming model and the 10Base-T twisted-pair interface. New designs should also evaluate newer Ethernet controllers or PHYs when 100Base-TX, gigabit Ethernet, or a serial Media Independent Interface is required. For implementation, begin with the manufacturer's pin-description and reference-circuit information, then verify every signal voltage, termination arrangement, and crystal or clock requirement against the board design. The 140 mA supply-current figure and 5 V operating range should be included in the power-budget calculation. Commercial availability, lifecycle status, and long-term sourcing commitments should be confirmed before starting a new production design. This page combines package, electrical, application, cross-reference, and design-placement information in one engineering reference. It also distinguishes genuine same-package alternatives from broader Ethernet-controller alternatives whose interfaces or packages differ, helping designers avoid treating functional similarity as proof of drop-in compatibility.
DP83936AVUL-20 20MHz Ethernet Controller | Texas Instruments
The Texas Instruments DP83936AVUL-20 is a 20 MHz full-duplex SONIC-T systems-oriented network interface controller with a twisted-pair interface, designed for high-speed 32-bit and 16-bit systems. It uses a parallel host interface, operates from a 4.75 V to 5.25 V supply, and is housed in a 160-pin square QFP package measuring 28 mm by 28 mm. An Ethernet network interface controller is a semiconductor that manages frame processing and the physical connection between a computer or embedded system and a network. The DP83936 belongs to the SONIC-T family, a second-generation Ethernet controller architecture intended for systems requiring parallel data movement, direct memory access, and support for both 16-bit and 32-bit host buses. The -20 suffix identifies the 20 MHz operating-speed option. According to the manufacturer datasheet, the device supports a 32-bit non-multiplexed address and data bus, full-duplex operation, and a twisted-pair network interface. A supply current of 140 mA is listed for the device, while its 4.75 V to 5.25 V operating supply range is centered on a conventional 5 V system rail. The parallel host architecture differentiates the DP83936 from compact Ethernet controllers based on serial or reduced-width interfaces. Parallel address and data paths can provide high throughput for systems processing substantial Ethernet traffic, particularly embedded routers, industrial gateways, telecommunications equipment, and legacy computing platforms. The 160-pin package exposes the extensive address, data, control, interrupt, and network-related signals required by this architecture. Typical applications include embedded Ethernet routers, industrial control gateways, network-interface subsystems, communications equipment, and other 5 V systems using a 16-bit or 32-bit processor bus. The controller can also serve as the Ethernet basis for a platform requiring a dedicated network interface rather than a highly integrated controller with an internal CPU. PCB design requires careful attention to the 160-pin footprint, 5 V power distribution, high-speed parallel routing, and transmission-line behavior on the host bus. Follow the manufacturer’s pin-description table and layout guidance when assigning every signal, especially reset, interrupt, address, data, and twisted-pair connections. This product page organizes the controller’s principal electrical, packaging, and interface characteristics, practical application considerations, verified sourcing links, and design guidance. It also distinguishes the 20 MHz device from other SONIC-T clock options so engineers can assess timing compatibility before approving a replacement.
DP83936AVUL-25 - 25MHz Ethernet Controller | Texas Instruments
Texas Instruments DP83936AVUL-25 is a 25 MHz full-duplex SONIC-T Ethernet network interface controller with a twisted-pair interface, supplied in a 160-PQFP package measuring 28 mm by 28 mm. It combines a 32-bit non-multiplexed address and data bus with a 4.75 V to 5.25 V supply range and approximately 140 mA supply current. The suffix identifies the 25 MHz configuration within the DP83936AVUL family. An Ethernet network interface controller, or NIC, connects a computer or embedded system to an Ethernet physical layer. The DP83936AVUL belongs to the SONIC-T family of systems-oriented network interface controllers, combining packet-processing hardware with a parallel host-bus interface and twisted-pair network connectivity. This architecture allows network communication to be implemented in 32-bit and 16-bit systems without relying on a software-driven standard network interface. The principal operating features include a 25 MHz clock configuration, full-duplex operation, a 32-bit non-multiplexed address and data bus, and an integrated twisted-pair interface path. The 4.75 V to 5.25 V operating range is compatible with conventional 5 V digital equipment, while the approximately 140 mA supply current provides a defined basis for power-budget calculations. Its parallel interface gives system designers direct access to the controller's internal descriptor, packet, and buffer resources. The DP83936AVUL family was designed for high-speed 32-bit and 16-bit systems in which deterministic host-bus access and direct Ethernet packet handling are important. The 160-lead package provides a large number of address, data, control, interrupt, network, and power connections, supporting integration with systems that use a non-multiplexed parallel architecture. Its operating frequency is the principal distinction among the DP83936AVUL-20, DP83936AVUL-25, and DP83936AVUL-33 configurations. Typical applications include industrial embedded controllers, data-acquisition equipment, laboratory instruments, print servers, industrial networking equipment, and legacy-compatible embedded systems requiring a parallel-bus Ethernet controller. In these systems, the DP83936AVUL can manage Ethernet packet traffic while the host processor accesses transmit and receive buffers through the parallel bus. The external twisted-pair interface also requires suitable magnetics and network-line implementation in the final design. A key design consideration is that this controller uses a high-pin-count package and a parallel host bus, so routing, termination, decoupling, and signal-integrity planning require more PCB attention than a compact serial-interface Ethernet device. Follow the manufacturer's pin-description and layout guidance in the DP83936AVUL datasheet, place bypass capacitors close to the supply pins, and use a multilayer board with a continuous ground reference when routing the address and data buses. This product record combines the manufacturer's family description, exact operating specifications, package information, source links, application engineering guidance, and a careful assessment of replacement constraints. It also distinguishes the 25 MHz device from frequency variants while avoiding unsupported claims about lifecycle, environmental ratings, and pin-level functions.
DP83936AVUL-33 - 33MHz Ethernet Controller | Texas Instruments
Texas Instruments DP83936AVUL-33 is a 33 MHz full-duplex SONIC-T systems-oriented network interface controller with an integrated 10 Base-T twisted-pair interface. It uses a 32-bit non-multiplexed address and data bus and is packaged in a 160-pin PQFP measuring 28 x 28 mm. The controller is designed for 16-bit and 32-bit systems requiring dedicated Ethernet packet-processing and network-interface functionality. A network interface controller, or NIC, is the subsystem that moves framed Ethernet data between a host processor and the physical network layer. The DP83936 belongs to the SONIC-T controller family and combines packet handling, buffer management, bus interfacing, and twisted-pair connectivity. Its parallel bus architecture separates high-throughput host access from the Ethernet medium, allowing systems to use dedicated Ethernet hardware instead of implementing the complete protocol stack in general-purpose logic or software. The DP83936AVUL-33 operates from 4.75 V to 5.25 V and requires approximately 140 mA supply current. It supports 10 Base-T operation through its twisted-pair interface and operates in a commercial temperature range of 0°C to +70°C. The 33 MHz suffix identifies the 33 MHz SONIC-T configuration, while the AVUL suffix identifies the 160-pin PQFP package option used by this ordering code. The controller is designed around a 32-bit non-multiplexed address and data bus, providing distinct address and data paths to the host system. This organization can reduce bus contention compared with a shared multiplexed interface and supports efficient access to the controller's internal packet buffers. Host-side software and hardware must follow the timing requirements and pin definitions in the manufacturer datasheet, particularly for bus-request, hold, and chip-select signaling. Typical applications include embedded industrial Ethernet equipment, embedded computing platforms, network appliances, printer controllers, telecommunications equipment, and other systems that need a dedicated 10 Base-T interface. Because the DP83936AVUL-33 is designed for legacy 10 Base-T networks, a current design should confirm that 10 Base-T remains a requirement before committing to this controller. Systems requiring Fast Ethernet, gigabit Ethernet, or a compact two-wire Ethernet PHY should evaluate a newer Ethernet interface family instead. The principal design consideration is PCB integration. A 160-pin PQFP requires careful escape-routing around all four sides of the device, while the parallel host bus demands short, impedance-conscious routing and complete decoupling of the 5 V supply. The 28 x 28 mm footprint is substantially larger than contemporary leadless Ethernet devices, so board area and assembly requirements should be considered before using an existing SONIC-T board in a new design. This product page consolidates the controller identity, operating limits, package details, comparison parameters, and practical integration considerations from the Texas Instruments datasheet and distributor technical records. It also distinguishes the verified frequency and package variants from broader Ethernet-controller alternatives, helping engineers assess footprint reuse, bus timing, thermal conditions, and legacy-network suitability before committing a board layout.
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. This page consolidates the verified distributor information, package identification, application guidance, and sourcing considerations for engineers evaluating the DP83950BVQB.
DP83953VUL - 13-Channel Ethernet Repeater | Texas Instruments
Texas Instruments DP83953VUL is a 13-channel IEEE 802.3 Ethernet repeater interface controller with security features, internal drivers, and integrated filters, supplied in a 160-pin QFP package. The device operates from a 4.75 V to 5.25 V supply and is specified with an 870 mA supply current. Its repeater-controller architecture is designed for extending and organizing Ethernet links in systems that require controlled propagation through multiple network ports. An Ethernet repeater interface controller is a physical-layer network interface device that manages signal transmission and reception across Ethernet ports. It belongs to the hierarchy of Ethernet interface controller, network interface controller, interface IC, and semiconductor. Unlike a conventional endpoint controller, the DP83953 is intended for repeater-node equipment where shared transmission media and port segmentation must be handled predictably rather than through a host-based protocol stack. The verified device description identifies three principal capabilities: security features, internal drivers, and integrated filters. Internal drivers support the controller’s Ethernet-facing transmit function, while integrated filters reduce unwanted signal activity at the interface. The 13-channel configuration allows one device to manage multiple repeater channels, making it suitable for concentrated port-count designs. Its 4.75 V minimum and 5.25 V maximum supply limits define a conventional 5 V operating region. The supplied 870 mA current rating is a significant design consideration because the controller may require more supply capacity than a basic low-power interface IC. A system designer should verify the device’s operating-current distribution across enabled channels, termination requirements, and thermal conditions against the manufacturer datasheet. The 160-QFP package provides a high pin count suitable for numerous repeater-port connections, clock, control, power, and status assignments. Typical applications include industrial Ethernet repeater chassis, network-interface concentrators, factory-floor communication equipment, and embedded Ethernet switching infrastructure. The DP83953 is particularly relevant where multiple 10 Mb/s-class Ethernet segments require a physical repeater controller rather than an endpoint media-access controller. Its integrated filtering and driver functions can simplify implementation compared with a discrete repeater design. When planning a board around the DP83953VUL, begin with the official manufacturer datasheet to confirm the complete 160-pin assignment, recommended magnetic-interface components, external filtering, decoupling, and thermal requirements. PCB designers should preserve the exposed signal paths and grounding structure required by the Ethernet interface and validate emissions, return loss, and fault isolation with representative cabling. This page consolidates verified distributor specifications, package information, sourcing links, and design cautions for faster component evaluation.

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.
DP83TC812SRHARQ1 - 100BASE-T1 Auto Ethernet PHY | Texas Instruments
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. This page synthesizes distributor pricing, drop-in VQFN-36 alternatives, application recommendations, and practical design notes not found in the manufacturer datasheet, optimized for engineers evaluating automotive Ethernet PHYs.
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.
DP83TG720RWRHATQ1 - 1000BASE-T1 Auto Ethernet PHY | TI
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 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. This page synthesizes distributor pricing, AEC-Q100-qualified drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone.
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. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
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.

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.

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.
