DP83849IDVS - Dual-Port 10/100 Ethernet PHY | Texas Instruments

The Texas Instruments DP83849IDVS is a dual-port 10/100-Mbps Ethernet PHY transceiver with fiber support, industrial-temperature operation from -40°C to +85°C, and an 80-pin TQFP package measuring 12 mm by 12 mm. The device provides two independently managed Ethernet physical-layer channels for copper and fiber links, making it suitable for industrial networking equipment requiring more than one 10/100-Mbps port. An Ethernet PHY is a physical-layer transceiver that converts digital data into electrical or optical signaling suitable for network transmission and receives signals back into digital data. In the product hierarchy, the DP83849IDVS is an Ethernet PHY transceiver, a network interface IC, an integrated circuit, and a semiconductor. Its dual-port architecture supports equipment that needs redundant connectivity, management access, or simultaneous links within a single device. The verified manufacturer information identifies the DP83849IDVS as a dual-port 10/100-Mbps Ethernet PHY transceiver with fiber support. Its -40°C to +85°C industrial-temperature range supports deployment in factory automation, industrial control, communications equipment, and network infrastructure. The 80-pin TQFP package provides access to the PHY functions, power connections, management interfaces, and copper or fiber-related signaling required by the device. The dual-port configuration is the primary technical distinction. Two physical-layer channels can reduce the number of separate Ethernet PHY packages needed in a multi-port system, simplifying board allocation while preserving independent 10/100-Mbps operation. Detailed electrical characteristics, register functions, media interfaces, and internal architecture are not present in the supplied source excerpts and therefore remain subject to the complete manufacturer datasheet. Typical uses include industrial Ethernet switches, remote monitoring stations, factory-floor controllers, communications equipment, and network-interface modules. The DP83849IDVS is particularly relevant where two copper ports and fiber-capable connectivity must coexist in an industrial-temperature design. The manufacturer also identifies the DP83849IDIFVS-EVK as a related evaluation platform for dual industrial-temperature PHY operation with fiber support. Designers should verify the complete pin assignment, recommended transformer or magnetics interface, strap resistors, clocking requirements, and decoupling network against the manufacturer datasheet before layout. Because the supplied data identifies a 12 mm by 12 mm 80-pin TQFP package but does not provide the complete 80-pin pinout, the package drawing cannot be safely populated here. This page combines verified manufacturer and distributor information, pricing availability status, same-family alternatives, comparison parameters, and application guidance. It also distinguishes documented facts from engineering data that remains unavailable, helping engineers evaluate the DP83849IDVS without confusing approximate or unsupported specifications.

DP83849IDVSX/NOPB

DP83849IDVSX/NOPB - Dual 10/100 Ethernet PHY | TI

Texas Instruments DP83849IDVSX/NOPB is a dual-port 10/100-Mbps Ethernet PHY transceiver with fiber support, designed for industrial-temperature operation. The device operates from a 3 V to 3.6 V supply and is packaged in an 80-pin TQFP (PFC) package measuring 12 mm by 12 mm. It provides two transmit and two receive channels for copper-based Ethernet links while also supporting fiber-oriented network designs. An Ethernet PHY transceiver is the physical-layer interface between a network controller or embedded system and an Ethernet medium. The DP83849IDID family operates within the 10BASE-T and 100BASE-TX Ethernet hierarchy, translating logical data into physical signaling and recovering data from received signals. A dual-port PHY can support two independent links, making it useful where equipment needs redundant connectivity, network management access, or simultaneous communication between wired network segments. The DP83849IDVSX/NOPB combines two 10/100-Mbps channels, a 3.3 V-class operating supply, and fiber support in one integrated component. Its industrial temperature range of -40 °C to 85 °C supports deployments across factory automation, industrial networking, wireless remote base stations, and embedded communications equipment. The 80-pin TQFP package exposes separate PHY channels and associated interface signals while enabling conventional multilayer-board assembly. The X suffix in the orderable identifier identifies the reel-packed form used for automated production, while NOPB denotes the lead-free finish. The physical package is designated PFC by Texas Instruments and contains 80 pins. Because the PHY interfaces with external magnetics, cabling, and a network controller, correct reference-design connectivity, controlled impedance routing, and correct termination are as important as the device's headline speed and port count. Typical applications include dual-port industrial Ethernet equipment, factory floor controllers, networked sensors, embedded gateways, remote base-station equipment, and systems requiring copper and fiber connectivity options. Each port can serve a 10-Mbps or 100-Mbps Ethernet segment, while the common 3.3 V supply simplifies system power architecture in industrial and communications equipment. Designers should place the PHY, its crystal or clock source, magnetic-interface components, and decoupling capacitors according to the manufacturer's reference layout. Maintain short, controlled-impedance traces for high-speed signals, provide clean return paths, and observe the exact pin assignments and external component values in the Texas Instruments datasheet before releasing a PCB layout. This product guide combines the verified ordering information, core operating characteristics, package details, and practical design considerations for the DP83849IDVSX/NOPB. It also distinguishes a true same-footprint replacement from reel and tray ordering variants, helping engineers evaluate PCB reuse without overlooking assembly, lifecycle, or signal-integrity constraints.

DP83849IFVSX/NOPB

DP83849IFVSX/NOPB - Dual-Port 10/100 Ethernet PHY | TI

Texas Instruments DP83849IFVSX/NOPB is an industrial-temperature, dual-port 10/100-Mbps Ethernet physical-layer transceiver with fiber support and flexible port switching, housed in an 80-pin TQFP package measuring 12 x 12 mm. The device provides two independent Ethernet transceiver channels and operates from a 3.3 V supply. Its fiber-capable feature set allows copper and optical network connectivity to be incorporated into industrial equipment, redundant networking systems, and communication infrastructure. An Ethernet physical-layer transceiver, commonly called an Ethernet PHY, converts digital data into signals suitable for transmission over copper or fiber media while recovering incoming signals and supporting standard link negotiation functions. Within the network hierarchy, a PHY sits between a MAC or network controller and physical communication media, connecting higher-level Ethernet packet processing to 10/100-Mbps physical-layer interfaces. The DP83849IF series is intended for applications requiring more than one Ethernet port. Its dual-port architecture can support equipment-management networks, redundant links, industrial controllers, remote base stations, and network switches. Flexible port switching adds board-level configuration flexibility for designs that must route communication resources according to system operating mode. Fiber support distinguishes this variant from copper-only members of the family and supports links over optical media where distance, isolation, or electrical-environment considerations favor fiber. The industrial-temperature classification makes the device appropriate for equipment expected to operate beyond commercial-temperature environments. Its 80-pin TQFP package exposes the dual-channel circuitry and associated configuration, clock, power, media, and control interfaces. The 12 x 12 mm package is substantially larger than compact QFN Ethernet PHYs, but that footprint provides a practical path to a high pin count and can simplify routing in equipment with multiple copper and fiber interfaces. Typical applications include industrial Ethernet gateways, dual-port network controllers, remote monitoring equipment, industrial switches, remote base stations, and optical network interfaces. When two ports serve different media or redundant network paths, the transceiver should be paired with a suitable Ethernet MAC, magnetic-interface components for copper links, optical components for fiber links, and a layout that isolates sensitive clock and data signals. The primary design considerations are power-supply integrity, media-interface component selection, clock quality, thermal performance, and signal routing around the two channels. Follow the manufacturer's pin-description table and reference layout when assigning PCB tracks. Decoupling capacitors should be placed close to the appropriate supply pins, and copper and fiber media interfaces must be routed according to the recommended topology to avoid degrading signal integrity or electromagnetic performance. This page organizes the available device specifications, sourcing information, design guidance, and carefully scoped replacement information. It also distinguishes exact drop-in compatibility from related family members whose fiber support or package construction differs, helping engineers determine whether a board can be reused without layout or functionality changes.

DP83849IVS/NOPB

DP83849IVS/NOPB - Dual 10/100 Ethernet PHY, 80-TQFP | Texas Instruments

The Texas Instruments DP83849IVS/NOPB is a dual-port 10/100 Mb/s Ethernet physical layer transceiver (PHYTER DUAL) with flexible port switching, factory-tested and specified for industrial temperature operation in an 80-pin TQFP (PFC) 12 x 12 mm package. It operates from a single 3 V to 3.6 V supply, supports MII, RMII and SNI media interfaces, and draws roughly 180 mA of supply current. An Ethernet PHY is the physical-layer device that converts digital MAC data into analog signaling over twisted-pair cabling, and back again. Within the network hierarchy it sits below the MAC controller (Ethernet controller -> Ethernet transceiver -> PHY -> magnetics -> RJ45) and is the block that governs link auto-negotiation, line coding, and signal integrity at the connector. A dual-port PHY with flexible port switching lets one physical transceiver serve two independent copper ports, which is valuable in industrial gateways, switches, and test equipment where port count is fixed but routing must be configurable. Key differentiating features include IEEE 802.3u compliance for 10BASE-T and 100BASE-TX, integrated cable diagnostics, JTAG 1149.1 test support for manufacturing bring-up, and the flexible port switching architecture that allows both ports to be exposed to the host, cascaded, or shared. The industrial temperature range of -40 C to +85 C and the Pb-free (NOPB) ordering code suit equipment that must survive harsh ambient conditions in factory, telecom, and building-automation cabinets. Technically, the device provides a compliant physical layer for Auto-Negotiation over twisted pair, including support for parallel detection of 10BASE-T and 100BASE-TX speeds. Because the MAC interface supports both MII, RMII and SNI, the same silicon can be paired with a wide range of host controllers, from low-cost 8-bit microcontroller-based gateways to 32-bit application processors with integrated Ethernet MACs. The 80-pin TQFP body exposes both PHY channels, bias networks, LED drivers, strap configuration pins, and reference clock and power planes on a single 0.5 mm pitch footprint. Typical applications include industrial Ethernet switches and bridges, PLC and factory automation controllers, network-attributed data acquisition equipment, telecom access units, and multi-port instrumentation racks. The DP83849IVS-EVK evaluation module from Texas Instruments is the reference platform for evaluating the device's link performance and port-switching configurations before production board layout. Designers should note that both PHY channels share a common 3.3 V supply and ground plane, so decoupling and return-path layout discipline matter more than with a single-port PHY. Keep the analog supply filtering and 1.8 V/3.3 V core rails consistent with the reference design, route differential pairs away from switching nodes, and observe the strap resistors before power-up because they define operating mode. This page consolidates manufacturer specifications, a drop-in cross-reference of compatible 80-pin TQFP PHYs, package details, and practical design notes that are normally spread across the datasheet, evaluation module documentation, and distributor listings.

DP83849IVSX/NOPB

DP83849IVSX/NOPB - Dual 10/100 Ethernet PHY | Texas Instruments

The Texas Instruments DP83849IVSX/NOPB is a dual-port 10/100-Mbps Ethernet physical-layer transceiver with flexible port switching for industrial networking equipment. The device operates from a 3.3 V supply, supports two integrated 10/100BASE-TX transceivers, and is offered in an 80-pin TQFP package measuring 12 x 12 mm. Its industrial temperature rating covers -40 °C to +85 °C. An Ethernet PHY, also called an Ethernet physical-layer transceiver, converts digital data into signaling suitable for copper-based Ethernet networks and recovers data from incoming physical-layer signals. The DP83849I belongs to the transceiver hierarchy, where PHY functionality sits below the Ethernet MAC and above the physical medium. Integrating two PHYs with flexible port switching lets one host processor manage two copper ports and route traffic according to application requirements. Key characteristics include dual-channel 10/100-Mbps operation, configurable port switching, an 80-pin TQFP package, and a 3.3 V operating supply. The part is intended for industrial Ethernet systems where temperature range and dual-port integration simplify board planning compared with using two separate single-port transceivers. Because the PHY handles the analog and digital signaling layer, the surrounding host design still requires an Ethernet MAC or a controller with an appropriate media-access interface. Typical uses include industrial Ethernet switches, network interface controllers, media-conversion equipment, embedded control systems, and dual-port industrial gateways. The flexible switching architecture can support designs in which both PHY ports contribute to a single switching function rather than operating as completely independent interfaces. Designers should confirm the required port configuration, media-access interface support, reference design topology, and magnetics requirements against the manufacturer datasheet before layout begins. A key implementation consideration is that the 80-pin TQFP footprint requires careful routing of high-speed differential pairs and supply connections. Keep the differential pairs short, continuous, and referenced to a solid ground plane, then place the interface protection and magnetic components in line with the manufacturer reference layout. Use the pin-description table in the manufacturer datasheet when assigning every PCB track, and validate cable, magnetics, and isolation requirements for the deployed industrial environment. This page organizes the manufacturer ordering information, verified distributor listings, package details, drop-in alternatives, and practical interface-design guidance into one engineering-focused reference for dual-port 10/100-Mbps Ethernet designs.

DP83850CVF

DP83850CVF - 100Mb/s Ethernet Repeater | Texas Instruments

Texas Instruments DP83850CVF is a 100 Mb/s TX/T4 Ethernet repeater interface controller with a 4.75 V to 5.25 V supply, 295 mA supply current, and a 132-pin PQFP package measuring 24.13 mm by 24.13 mm. The device is designed for IEEE 802.3u-compatible repeater and management interfaces, making it suitable for legacy 100BASE-TX and 100BASE-T4 network equipment. An Ethernet repeater is a physical-layer network component that regenerates and forwards received Ethernet signals between network segments. It belongs to the Ethernet interface controller category, the Ethernet interface hierarchy, and ultimately the broader semiconductor and network interface product classes. Repeaters are used where signal integrity, segment extension, or centralized network topology requires an active Ethernet signal-conditioning function rather than a conventional packet-switching bridge. The DP83850CVF operates from a single 4.75 V to 5.25 V supply and is listed at a supply current of 295 mA. Its principal data rate is 100 Mb/s. The 132-pin PQFP package provides 132 external connections for repeater, management, data, control, status, and power functions. It is offered in tray packaging according to the available component data, and distributor records identify it as a commercial-temperature-grade component. Compared with a basic Ethernet transceiver, the DP83850CVF is specifically identified as a TX/T4 repeater interface controller. Its IEEE 802.3u compatibility indicates positioning for Fast Ethernet repeater applications rather than modern switched Ethernet ports. The device can therefore be useful in legacy industrial networking, embedded communication equipment, test systems, and installed infrastructure that retains 100 Mb/s repeater-based connections. A key design consideration is that the DP83850CVF requires careful separation between high-speed signal routing, digital control interfaces, and the 5 V supply network. The exact pin names, termination requirements, and timing constraints must be taken directly from the manufacturer datasheet before layout because the supplied records do not expose a complete verified pin table. Magnetics, connector layout, controlled-impedance routing, and decoupling also remain system-level requirements for a dependable Ethernet physical-layer implementation. This page consolidates the verified manufacturer and distributor information for the DP83850CVF, documents the uncertainty where detailed technical values are unavailable, and distinguishes genuine drop-in alternatives from related but potentially different-package Ethernet controllers. It is intended to support component identification and sourcing decisions without implying that unspecified electrical or pin-level details are interchangeable.

DP83858VF

DP83858VF - 8-Port 100 Mb/s Ethernet Repeater | Texas Instruments

The Texas Instruments DP83858VF is a 100 Mb/s TX/T4 Repeater Interface Controller, also identified as 100RIC8, supporting up to eight 100 Mb/s Ethernet ports in a 132-PQFP package. The supplied data specifies a 4.75 V to 5.25 V supply range, 295 mA supply current, and IEEE 802.3 compatibility. An Ethernet repeater controller is an interface IC within the Ethernet networking hierarchy. It coordinates multiple 100 Mb/s network segments, regenerates and retimes received signals, and provides the control logic needed by low-port-count managed or unmanaged repeater systems. The DP83858 targets equipment that must extend Fast Ethernet connectivity across several ports without using eight separate external repeater controllers. The controller's defining features include support for as many as eight 100 Mb/s ports, 100 Mb/s TX/T4 operation, 5 V single-supply operation, and compatibility with the IEEE 802.3 repeater requirements identified in the manufacturer documentation. The 295 mA supply-current figure provides a basis for power budgeting, while the 132-PQFP mechanical format supports a substantial pin count for port-facing signals and control functions. The DP83858 belongs to the interface-controller category rather than a general-purpose transceiver. Its TX/T4 repeater architecture is intended for high-speed Ethernet systems and legacy Fast Ethernet infrastructure. Compared with a single-port PHY, the device concentrates repeater management and media-interface control for an eight-port system, reducing board-level component count while retaining a standardized networking architecture. Typical applications include managed Fast Ethernet switches, unmanaged low-port-count switches, Ethernet repeaters, industrial network concentrators, and legacy 100BASE-TX equipment. Installation requires careful PCB routing for high-speed differential pairs, solid supply decoupling, controlled return paths, and compliance with the manufacturer's recommended layout and termination practices. The main design trade-off is specialization: DP83858VF addresses multiport Fast Ethernet repeater control rather than modern multi-gigabit or single-port integrated PHYs. Legacy-system maintenance, industrial connectivity, and equipment replication are stronger reasons to select it than new high-bandwidth designs. This page consolidates the supplied manufacturer-related data, distributor listing, package information, and Ethernet application context. It also distinguishes verified specifications from parameters that require confirmation from the complete datasheet before schematic or PCB release.

DP83861VQM-3

DP83861VQM-3 - 10/100/1000 Ethernet PHY | Texas Instruments

Texas Instruments DP83861VQM-3 is a 10/100/1000M Ethernet physical-layer transceiver with integrated PMD sublayers and support for 10BASE-T, 100BASE-TX, and 1000BASE-T links. The device is supplied in a 208-PQFP package measuring 28 mm by 28 mm. The -3 ordering suffix identifies the grade, but further grade-specific electrical and environmental details require confirmation from the manufacturer datasheet. The DP83861 family is intended for systems that connect an Ethernet controller or digital processor to a copper network through an RJ45 magnetics interface. An Ethernet physical-layer transceiver, commonly called an Ethernet PHY, converts between digital MAC-layer data and analog signaling on twisted-pair cabling. Within the Ethernet hierarchy, the PHY operates below the MAC controller and above the physical medium. Its supported 10BASE-T, 100BASE-TX, and 1000BASE-T capabilities allow one physical interface to cover 10 Mb/s, 100 Mb/s, and 1000 Mb/s Ethernet operation. The associated GMII and MII interfaces connect the transceiver to the digital networking controller. The verified listing identifies the DP83861 as a full-featured Gigabit PHY that complies with IEEE 802.3u for 100BASE-TX and IEEE 802.3z/ab for 1000BASE-T Ethernet. It also identifies support for 10BASE-T operation. These protocol references establish the covered Ethernet generations, although individual timing, error, power, and link-performance limits are not present in the supplied source excerpts and are therefore marked for data confirmation rather than inferred. Typical implementations place the DP83861VQM-3 beside a network transformer and RJ45 connector, then connect its GMII or MII interface to an Ethernet MAC controller or communications processor. The large 208-pin PQFP provides a substantial mixed-signal interface, making careful grounding, controlled return paths, and high-speed differential routing important. Designers should separate analog PHY and magnetics-side return currents from digital processor and memory domains while observing the package and layout guidance in the manufacturer documentation. Applications include industrial Ethernet controllers, embedded gateways, network switches, test equipment, and communications modules requiring copper Ethernet connectivity. The part may also support migration paths from 10/100-Mb/s equipment to 1-Gb/s links when the complete PHY, transformer, connector, clocking, and firmware architecture can support the higher data rate. Automatic-negotiation details, supported media categories, cable reach, and media-access configuration must be confirmed in the manufacturer datasheet before final design release. This page consolidates the supplied distributor listings, package information, protocol references, sourcing data, and engineering guidance into a structured component record. It distinguishes verified facts from parameters that remain unavailable in the supplied excerpts. Any replacement decision should be based on pin-level comparison, media support, electrical limits, clock requirements, firmware register compatibility, and PCB-level validation rather than package naming alone.

DP83865BVH

DP83865BVH - 8/8 Gigabit Ethernet PHY | Texas Instruments

The Texas Instruments DP83865BVH is an 8/8 Gigabit Ethernet physical-layer transceiver with integrated support for 10BASE-T, 100BASE-TX, and 1000BASE-T operation, supplied in a surface-mount 128-pin PQFP package measuring 14 x 20 mm. Its verified operating supply information includes 1.8 V and 2.5/3.3 V rails, while its transceiver architecture connects an Ethernet MAC through a digital parallel interface to copper cabling. An Ethernet physical-layer transceiver, commonly called an Ethernet PHY, is the semiconductor layer that converts logical data transmitted by a network controller into electrical or optical signals suitable for a communications medium. Within the Ethernet hierarchy, a PHY sits below the MAC and above the physical medium. For copper Ethernet, the PHY handles encoding, signaling, clock recovery, link negotiation, and reception of data transmitted over twisted-pair cabling. The DP83865BVH is identified as an 8/8 transceiver, providing eight transmit and eight receive channels for parallel network-interface implementations. Verified source data identifies 10BASE-T and 100BASE-TX support and notes integrated PMD sublayers associated with 1000BASE-T operation. This makes the device relevant to multiport Ethernet switches, routers, network interface controllers, and industrial communication equipment requiring several copper ports. The 128-PQFP package is physically substantial compared with compact QFN Ethernet PHYs because it exposes a broad high-speed parallel interface, multiple PHY channels, supply rails, reference clocks, and copper-network connections. Its surface-mount construction supports automated assembly, but careful power-plane distribution, controlled clock routing, and high-speed signal-integrity management remain necessary in multi-channel Ethernet designs. Typical applications include 8-port Gigabit Ethernet switches, network interface cards, routers, industrial Ethernet equipment, and embedded communication systems. The 8/8 organization can reduce the number of discrete PHY devices required when several copper ports share one board, although system partitioning, thermal distribution, and magnetics selection must still be evaluated. For a new design, engineers should use the official Texas Instruments datasheet and pinout rather than assigning connections solely from generic Ethernet conventions. Verify every supply rail, transceiver channel, clock input, resistor network, magnetic-interface component, and exposed thermal or supply connection against that document before layout release. This page consolidates verified distributor specifications, package data, sourcing links, application context, and compatibility cautions. Its key information gain is the distinction between a true pin-to-pin replacement and a merely similar 8/8 Ethernet PHY, which prevents an electrically or mechanically invalid substitution.

DP83865DVH

DP83865DVH - 1G Ethernet PHY, 128-PQFP | Texas Instruments

The Texas Instruments DP83865DVH is a single-port Gigabit Ethernet physical-layer transceiver supporting 10BASE-T, 100BASE-TX, and 1000BASE-T in a 128-PQFP package measuring 14 x 20 mm. It operates from a 1.71 V to 1.89 V core supply and supports data rates through 1 Gbit/s. The commercial-temperature device is specified for 0 C to +70 C and has eight media-interface transmit or receive channels. An Ethernet PHY is the physical-layer component that converts digital Ethernet data supplied by a MAC into electrical signaling for a copper network, and receives analog signals from the cable. Within the Ethernet hierarchy, the PHY connects the digital MAC interface and the 10/100/1000BASE-T medium. This distinction matters because protocol handling remains above the PHY while the DP83865DVH performs line signaling, clock and data recovery, and physical-layer encoding functions. Verified source data identifies a 1 Gbit/s data rate, eight transceiver channels, a 1.71 V to 1.89 V supply range, approximately 430 mA supply current, and a 128-pin PQFP package. The device integrates physical medium-dependent sublayers required for 10BASE-T, 100BASE-TX, and 1000BASE-T Ethernet. Exact media-interface modes, clock tolerances, transceiver electrical limits, and pin-level functions are not present in the supplied search extracts and therefore require confirmation from the manufacturer datasheet before layout release. Typical implementation is a copper Gigabit Ethernet port in industrial controllers, embedded computers, test equipment, network interface cards, and communications hardware. The 128-PQFP footprint favors multilayer PCB routing and external magnetics rather than compact modules, while the 1.89 V maximum stated core supply requires a regulator with suitable headroom and power integrity. A network magnetics or integrated coupling arrangement is also required at the cable side, subject to the complete reference design. Engineers should preserve the exact interface voltage, termination, crystal or clock source, reset, and power-tree requirements given in the full DP83865 datasheet. Because no verified pricing schedule was supplied, unit prices remain marked as data needed rather than being inferred from generic distributor listings. The search data also indicates that no pin-to-pin DP83865 replacement is offered by TI, so substitution requires interface and PCB validation rather than an assumed footprint match. This page consolidates the verified distributor specifications, procurement sources, replacement evidence, and engineering cautions. It distinguishes confirmed electrical facts from unavailable details and avoids treating functionally similar PHYs as verified drop-in devices. That distinction is critical because Ethernet PHYs may use the same 128-pin package while differing in interface modes, strap behavior, clocking, register maps, and analog performance.

It supports 10BASE-T, 100BASE-TX, and 1000BASE-T protocols and is designed for copper Ethernet links requiring integrated PHY functions in a compact surface-mount package. An Ethernet physical-layer transceiver, commonly called an Ethernet PHY, is the semiconductor interface between a digital network controller and twisted-pair cabling. The PHY converts digital data into electrical signaling, performs line coding and signal conditioning, and supports the physical protocols used by 10 Mb/s, 100 Mb/s, and 1 Gb/s Ethernet. The DP83867 family places this network-access function within the broader hierarchy of Ethernet controller, network interface controller, interface IC, and semiconductor. The DP83867CRRGZR provides a single 10/100/1000BASE-T Ethernet channel and supports both RGMII and SGMII host interfaces. According to the Texas Instruments product information, the device is a robust, low-power physical-layer transceiver with integrated PMD sublayers. The RGZ package contains 48 pins, and the commercial-temperature ordering option is specified for 0°C to 70°C. The RGMII interface provides a parallel digital connection for a compatible Ethernet controller, while SGMII provides a high-speed serial interface for systems that use serial Ethernet links. The integrated PMD sublayers support 10BASE-T, 100BASE-TX, and 1000BASE-T operation. This coverage lets one physical design accommodate 10 Mb/s and 100 Mb/s legacy links as well as 1 Gb/s links, subject to the capabilities of the connected switch, router, network interface controller, and cabling infrastructure. The manufacturer also identifies cable diagnostics, IEEE 1588 support, and a JTAG 1149.1 debug interface as features of the DP83867 family comparison information. Typical applications include industrial Ethernet equipment, industrial automation controllers, network switches, routers, test equipment, servers, and embedded platforms that connect a digital Ethernet controller to a single copper port. In these systems, the PHY is normally paired with a host controller that handles higher-layer traffic and configuration, while the DP83867CRRGZR manages the physical medium. RGMII is useful when the host controller exposes a parallel interface; SGMII is useful when the system architecture favors a serial link between MAC and PHY. Layout and power design remain central to reliable operation. Place the PHY, magnetic-interface components, crystal or clock source, and decoupling capacitors according to the manufacturer reference layout, and preserve the high-speed differential return paths. Account for the exposed thermal pad when evaluating temperature rise. Review interface timing, magnetics selection, and supported Ethernet standards against the manufacturer datasheet before releasing a production layout. This product page combines the exact ordering information, supported Ethernet rates, interface choices, package details, and temperature grade with practical replacement guidance. It also provides application-specific design context, comparison criteria, and an engineering checklist for evaluating the DP83867CRRGZR without changing the core Ethernet architecture.

Detailed electrical limits, clock requirements, register defaults, magnetic-component recommendations, and timing margins must be taken from the manufacturer datasheet before layout release. Typical applications include industrial Ethernet controllers, automated machinery, network switches, embedded Linux systems, test equipment, and industrial IoT gateways. The device is particularly relevant when a board needs 10/100/1000-Mbps copper Ethernet and the host controller supports RGMII or SGMII. For an RMII-only controller, the verified comparison information states that a bridging translator such as the Microchip LAN9354 is required. A critical design consideration is interface timing: RGMII clock and data paths must meet the required setup and hold windows, while the copper-channel magnetics, center taps, and termination network must follow the reference design. PCB layout should separate high-speed digital clocks from analog receive circuitry and provide a low-impedance, continuous return path beneath the PHY and magnetics. This page consolidates verified manufacturer and distributor information, supported PHY variants, interface-selection guidance, and practical integration considerations. It distinguishes documented facts from electrical details that still require confirmation from the current Texas Instruments datasheet, helping engineers evaluate the DP83867CRRGZT without relying on an unverified cross-reference listing.

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

Key headlines: 10/100/1000 Mbps operation, RGMII and SGMII MAC interface options, configurable I/O voltage (3.3 V, 2.5 V, 1.8 V), and an industrial-grade 0 C to 70 C operating range with TI's high-immunity PHY core. An Ethernet PHY (Physical Layer transceiver) is the analog/digital mixed-signal device sitting between a Media Access Controller (MAC) and the magnetics/RJ45 connector on a copper Ethernet link. The PHY handles line encoding/decoding (PAM-5 for 1000BASE-T, MLT-3 for 100BASE-TX), link training, echo cancellation, and cross-talk mitigation across four twisted pairs, while presenting a parallel or serial digital interface to the MAC. As a Physical Layer transceiver within the seven-layer OSI model, the PHY is part of the wired networking interface layer, and a critical power-management and signal-integrity IC in any embedded Ethernet design. Key features include cable diagnostics, low RGMII latency (TX < 90 ns, RX < 290 ns), Time-Sensitive Network (TSN) compliance, fast link drop mode, JTAG 1149.1 boundary scan support, and integrated PMD sublayers. The DP83867CS provides high ESD/EMC immunity and an ultra-low RGMII latency profile. Compared to integration assemblers using lower-immunity PHYs, the CS variant offers enhanced robustness for noisy industrial environments. Architecturally, the device uses TI's proprietary DSP-based echo canceller and baseline wander corrector across all four pairs, with auto-negotiation and Auto-MDIX, allowing direct connection to either a straight-through or crossover cable. The SGMII option reduces MAC-to-PHY pin count to four differential signals, freeing board area in space-constrained designs. Typical applications include industrial Ethernet switches, factory automation controllers, motor drives with EtherCAT/PROFINET support, building automation, and any embedded system requiring a small-footprint, low-power gigabit copper interface. The wide temperature range and immunity rating make the part especially suitable for industrial Ethernet switches and PLCs. When designing with this device, pay careful attention to MDI trace routing (100-ohm differential, length-matched within the pair), magnetics selection, and decoupling on each supply pin. Reference the TI DP83867 design checklist for layout guidance, especially the four-pair MDI routing and chassis-ground separation.

The device delivers extra-low latency (TX < 90 ns, RX < 290 ns) and is offered in an industrial extended-temperature grade with SGMII and RGMII MAC interfaces. An Ethernet PHY (Physical Layer transceiver) is a mixed-signal IC that connects a MAC controller to the copper medium (twisted-pair cable), handling line encoding/decoding, link training, echo/next-crosstalk cancellation, and clock/data recovery across the MDI. The DP83867E sits at the bottom of the OSI physical layer, translating digital MAC frames into analog baseband signals on the cable. In the taxonomy: Ethernet PHY -> transceiver -> network interface IC -> communication semiconductor. The part exceeds 8 kV IEC 61000-4-2 ESD on the cable pins, making it a robust choice for industrial and automotive-grade Ethernet links. Key features include support for both RGMII and SGMII MAC interfaces, integrated 1.25 GHz SerDes for SGMII, low-power 1000BASE-T operation, programmable LED outputs, and a flexible MDIO/MDC management interface. The extended-temperature grade (-40C to +105C ambient with proper thermal design) targets industrial control, factory automation, and outdoor equipment where commercial-grade PHYs derate. Architecturally, the DP83867E uses a DSP-based echo and crosstalk canceller, an integrated 1000BASE-T PMA/PMD with on-chip termination, and a low-jitter PLL to recover the 125 MHz reference. The SGMII variant routes the recovered data over a 1.25 Gbps differential serial link, eliminating the 12-bit parallel RGMII bus and reducing board-layer routing complexity in space-constrained SoMs. Typical applications include industrial Ethernet switches, programmable logic controllers (PLCs), factory-floor IO modules, motor drives, telecom base-station routers, and automotive Ethernet PHYs for in-vehicle networking. The SGMII interface in particular suits SoCs that place the PHY on a remote daughter card or that prefer serial MAC connectivity. Design consideration: the MDI traces require 100-ohm controlled differential impedance and an integrated magnetics RJ-45 with center-tap; the 1.0 V analog and 2.5/3.3 V digital rails must be cleanly decoupled to meet the IEEE 802.3 return-loss mask. Use the TI reference design checklist for BOM and stack-up.

The verified ordering information identifies a 48-VQFN RGZ package, a 7 mm square land pattern, a 0.5 mm lead pitch, and a tape-and-reel shipping format. RGMII provides a parallel digital interface for a conventional MAC-to-PHY connection, while SGMII provides a high-speed serial interface for designs that benefit from fewer signal connections. The available comparison data also identifies cable-diagnostics, IEEE 1588 support of the stated SOF type, and JTAG 1149.1 among the notable device features. Because the DP83867ERGZR is specified as an extended-temperature, robust, low-latency Gigabit Ethernet PHY, it is relevant to industrial automation, motor-drive systems, embedded routers, test equipment, and communications infrastructure. These systems benefit from a compact 48-pin surface-mount package and flexible RGMII or SGMII host connectivity. The exact supported link rates, electrical characteristics, clocking requirements, media-access procedures, and recommended external circuitry must be confirmed against the manufacturer datasheet before a board design is released. A critical implementation consideration is that the PHY is part of a high-speed mixed-signal system. Designers should follow the manufacturer’s reference layout, provide the specified power and decoupling networks, and route high-speed differential pairs as controlled-impedance transmission lines. Magnetics, RJ45 circuitry, clock sources, reset timing, and the exact operating mode also require validation in the complete system rather than substitution based only on package similarity.

RGMII is useful when the PHY is placed beside an Ethernet MAC in a high-performance system, while SGMII can simplify connections to serializers or controllers that support that interface. The same PHY can negotiate the link rate and support 10BASE-T, 100BASE-TX, or 1000BASE-T operation according to the connected network. A successful design must preserve high-speed signal integrity around the RGMII, SGMII, clock, and differential copper interfaces. Place decoupling capacitors close to the supply pins, use the recommended magnetics and impedance-controlled differential routing, and follow the exposed-pad thermal and assembly requirements. Do not substitute a non-drop-in transceiver solely because its headline data rate matches. This page organizes the manufacturer specifications, sourcing information, drop-in family options, application guidance, package constraints, and practical PCB considerations needed to evaluate DP83867ISRGZR before committing it to a design.

DP83867ISRGZT

DP83867ISRGZT Industrial Gigabit Ethernet PHY | Texas Instruments

The Texas Instruments DP83867ISRGZT is an industrial-temperature, single-port 10/100/1000 Ethernet physical-layer transceiver with RGMII and SGMII interfaces, operating from -40°C to +85°C in a 48-pin RGZ VQFN package. It supports 10BASE-T, 100BASE-TX, and 1000BASE-T protocols and uses 1.0 V, 1.8 V, and 2.5 V interface rails. An Ethernet physical-layer transceiver, or Ethernet PHY, is the semiconductor layer that converts digital Ethernet data into signals suitable for transmission over twisted-pair cable. It sits between a network controller or system-on-chip and the external RJ45 magnetic interface. Within the network architecture, the DP83867IS belongs to the PHY, physical-layer transceiver, Ethernet interface IC, and semiconductor hierarchies. The DP83867IS is positioned for industrial systems that require robust Gigabit Ethernet connectivity. Its operating-temperature range of -40°C to +85°C exceeds the range of typical commercial-temperature PHYs. A single-port architecture simplifies board routing, while RGMII support allows direct connection to many Ethernet controllers and SGMII support supports serial links to higher-speed fabric or switching silicon. The device integrates the physical-medium dependent sublayers required for 10BASE-T, 100BASE-TX, and 1000BASE-T operation. Supporting all three rates in one PHY permits a single copper-network design to accommodate legacy 10 Mbit/s and 100 Mbit/s endpoints as well as full-duplex Gigabit links. The availability of 1.0 V, 1.8 V, and 2.5 V interface rails supports integration with processors, FPGAs, switching fabrics, and industrial controllers operating at different logic levels. Typical applications include industrial Ethernet controllers, factory automation equipment, networked sensors, motor-drive systems, building-automation gateways, and embedded routers. The combination of RGMII and SGMII makes the device suitable for designs that must accommodate parallel MAC connections, serial fabric links, or platform variants using different network architectures. PCB implementation requires careful treatment of the exposed pad, analog supply rails, clock sources, and high-speed digital interfaces. Place the PHY close to the network connector and magnetics, route differential pairs as impedance-controlled pairs, and use a solid ground-plane arrangement beneath the device. Follow the manufacturer datasheet for the exposed-pad connection, decoupling capacitors, isolation boundaries, and analog-layout requirements. This page organizes the DP83867ISRGZT’s industrial Ethernet role, interface options, temperature range, package constraints, application guidance, drop-in candidates, and engineering considerations into a practical selection reference for designers building robust copper-based Ethernet equipment.
