DP83843BVJE - 10/100 Ethernet PHY | Texas Instruments
部品番号: DP83843BVJE ✗ 生産終了DP83843BVJE 概要
An Ethernet PHY is the physical-layer device that connects a digital network controller to copper or fiber media. Within the networking hierarchy, the DP83843BVJE belongs to the Ethernet transceiver and interface-controller category, then to interface ICs and, more broadly, integrated circuits. Supporting both 10BASE-T and 100BASE-X allows one physical-layer design to address legacy 10 Mb/s copper links and 100 Mb/s Fast Ethernet links using either copper twisted-pair or optical-compatible signaling paths.
The principal verified feature set includes IEEE 802.3 ENDEC operation, integrated PMD sublayers, support for 10BASE-T, support for 100BASE-X, four transmit drivers, and four receive drivers according to distributor product information. The manufacturer describes the device as a full-feature Physical Layer device intended to simplify implementation of 10/100 Mb/s Ethernet LANs. The 80-QFP package provides 80 physical terminals in a square gull-wing format.
Technically, the DP83843BVJE separates Ethernet MAC-facing functions from the analog and digital signaling required by physical media. Its integrated PMD sublayers place the 10BASE-T and 100BASE-X physical coding functions inside the transceiver, reducing the amount of external media-interface circuitry required in a typical LAN design. The available verified excerpt does not provide a complete electrical timing table, register map, magnetics recommendation list, or thermal characterization, so those details must be confirmed in the complete manufacturer datasheet before schematic release.
Typical uses include industrial Ethernet equipment, embedded network controllers, network interface cards, routers, switches, and other 10/100 Mb/s LAN equipment. In an industrial or embedded product, the transceiver can sit between an Ethernet MAC and the isolation or line-driver stage required by the selected 10BASE-T or 100BASE-X implementation. Board-level validation remains important because magnetics, clocking, termination, layout, and regulatory testing can determine whether a nominal PHY design functions reliably.
Designers should preserve the manufacturer-recommended power, ground, and signal-integrity layout and verify every external network component against the complete datasheet. In particular, the selected Ethernet magnetics or PHY-side interface components must match the supported media mode, while differential routing and return paths require disciplined PCB implementation. Do not infer unsupported rise-time, jitter, temperature, or package thermal values from the distributor summaries.
This product record combines the verified manufacturer description, distributor package information, source links, practical application context, and an explicit treatment of unavailable pin-level and electrical data. The comparison and validation notes distinguish confirmed facts from parameters that still require the full datasheet, allowing engineers to assess the DP83843BVJE efficiently without treating missing specifications as confirmed engineering data.

主な用途
DP83843BVJE の用途: 6 件s: Industrial Ethernet Control Equipment, Embedded Network Controller Interface, Network Interface Card Design, Router and Switch Line Cards, Factory Automation Ethernet Connectivity, Legacy 10/100 Mb/s LAN Upgrade.
Industrial Ethernet Control Equipment
The DP83843BVJE fits industrial Ethernet control equipment that must connect a digital controller to a 10/100 Mb/s LAN while supporting both 10BASE-T and 100BASE-X media modes. Its integrated PMD sublayers place the physical coding functions inside the transceiver, while the confirmed four-driver and four-receiver arrangement supports full-duplex Ethernet signaling. The 80-QFP surface-mount package is useful where an existing control-board layout already uses this footprint. Before finalizing the design, verify the operating-temperature range, EMC performance, recommended Ethernet magnetics, and power specifications in the full Texas Instruments datasheet, because those details were not available in the verified excerpts.
Embedded Network Controller Interface
The DP83843BVJE is suitable for embedded systems that include an Ethernet-capable microcontroller or dedicated MAC but require a separate physical-layer transceiver for the network connection. Supporting 10 Mb/s and 100 Mb/s operation allows the physical layer to accommodate legacy and Fast Ethernet network infrastructure. Its integrated 10BASE-T and 100BASE-X PMD sublayers reduce the media-interface burden compared with a more modular implementation. The design must still include the appropriate media magnetics or 100BASE-X interface components, clocking, isolation requirements, and PCB layout specified by the complete manufacturer datasheet.
Network Interface Card Design
A 10/100 Mb/s network interface card can use the DP83843BVJE as the Ethernet physical-layer element when the MAC, bus interface, magnetics, and connector are designed around the same device family. The confirmed support for both 10BASE-T and 100BASE-X provides flexibility in copper and fiber-facing implementations, and the integrated PMD sublayers simplify the lower PHY layers. The 80-QFP package requires careful gull-wing pad layout and adequate routing escape geometry. Engineers should confirm all pin functions and interface timing from the complete PDF before routing and should avoid relying on the abbreviated distributor listing for power, termination, or reference-design values.
Router and Switch Line Cards
The DP83843BVJE can be evaluated for 10/100 Mb/s Ethernet line cards in routers, switches, gateways, and network appliances that retain legacy Fast Ethernet ports. Its confirmed dual support for 10BASE-T and 100BASE-X allows a product family to cover copper twisted-pair and optical-compatible PHY interfaces, subject to the external circuitry required for each media mode. The device's 80-QFP package supports conventional surface-mount assembly but occupies more PCB area than compact Ethernet PHYs. Selection should account for clocking architecture, isolation, magnetics, thermal performance, and lifecycle availability, none of which can be fully confirmed from the supplied search excerpts.
Factory Automation Ethernet Connectivity
For factory automation, the DP83843BVJE can serve as a 10/100 Mb/s Ethernet PHY where equipment needs both 10BASE-T and 100BASE-X support and the 80-QFP footprint is already established. Integrated PMD functions help organize the media-facing implementation, but an industrial deployment still requires rigorous validation of temperature range, conducted and radiated emissions, immunity, cable fault behavior, and long-term supply. The available verified data does not provide those industrial qualifications, so engineers must treat the device as a candidate rather than a fully qualified industrial component until the missing datasheet and compliance information are reviewed.
Legacy 10/100 Mb/s LAN Upgrade
The DP83843BVJE is appropriate for an upgrade or repair that must retain a 10/100 Mb/s Ethernet architecture without changing the established 80-QFP board footprint. Supporting 10BASE-T and 100BASE-X can preserve compatibility with multiple media types, while the integrated PMD sublayers simplify the PHY-side signal chain. The most direct verified replacement is DP83843BVJE/NOPB, which the supplied comparison describes as functionally equivalent with the same pinout and package but a different RoHS status. A production migration should additionally verify lifecycle status, operating-temperature grade, clock requirements, and any PCB revision differences.

設計ノート
Route the DP83843BVJE media-side connections using the complete Texas Instruments application circuit and layout guidance. The verified excerpts establish an 80-QFP package and 10BASE-T/100BASE-X support, but they do not provide differential impedance, trace-length, via, or breakout dimensions. Confirm those details in the datasheet before fabrication, especially where the Ethernet interface changes from copper twisted pair to an optical-compatible 100BASE-X implementation.
Do not finalize the power tree until the supply voltages, current consumption, sequencing requirements, and decoupling values are obtained from the official DP83843 datasheet. Use the manufacturer-recommended bypass network and grounding arrangement rather than extrapolating from another 80-QFP Ethernet PHY. This prevents an apparently correct 10/100 Mb/s design from suffering from supply noise, startup instability, or inconsistent behavior between media modes.
Treat DP83843BVJE and DP83843BVJE/NOPB as pin-compatible based on the verified distributor comparison, but still compare the complete ordering information and datasheet revision before procurement. Their reported RoHS statuses differ, and the supplied excerpts do not confirm temperature range, lifecycle status, or identical lead-free construction. This makes the /NOPB version the more appropriate candidate for a new compliant design, subject to final manufacturer-document review.
Preserve the integrity of clock and data-interface paths by following the manufacturer's grounding and layout recommendations. The available data identifies four drivers and four receivers but provides no edge-rate, jitter, rise-time, or impedance values. Use the full datasheet to determine whether external filtering, controlled-impedance routing, or additional isolation is required for the selected MAC, clock source, and Ethernet magnetics.
コンプライアンス情報
The verified distributor comparison identifies DP83843BVJE as RoHS non-compliant and DP83843BVJE/NOPB as RoHS compliant. No explicit REACH, halogen-free, conflict-minerals, or AEC-Q100 information was supplied. AEC-Q100 is marked not_applicable because this is an Ethernet interface IC rather than an automotive-qualified device in the provided data.
