DP83843BVJE/NOPB - 10/100 Ethernet PHY | Texas Instruments
MPN: DP83843BVJE/NOPB ✓ نشطDP83843BVJE/NOPB نظرة عامة
An Ethernet PHY is a semiconductor within the physical layer of the Ethernet protocol stack. The PHY converts digital data and control signals into the electrical or optical signaling required by network media, while receiving and returning signals from the medium. A 10/100 Ethernet PHY supports both 10-Mbps and 100-Mbps operation, allowing a single physical interface to accommodate legacy and Fast Ethernet networks.
The device supports 10BASE-T and 100BASE-X Ethernet protocols through integrated PMD sublayers. Its 100BASE-X capability supports the fiber-oriented path identified by Texas Instruments, while the listed AUI support broadens the physical-media options available to the designer. This combination makes the DP83843 family useful in equipment that must bridge or interface multiple Ethernet physical-layer environments rather than using a copper-only 10/100 PHY.
The DP83843BVJE/NOPB is packaged in an 80-pin QFP (NNC), identified in the manufacturer part-details listing as a 14 x 14 mm package with a 0 to 70 C operating-temperature range. The dense 80-lead format provides numerous PHY, media, control, and power-related connections while supporting compact, surface-mount assembly. Pin assignments, exposed supply requirements, clocking provisions, and media-interface details should be taken directly from the manufacturer pin-description tables before schematic capture.
Typical uses include industrial Ethernet equipment, communications equipment, network-interface subsystems, embedded LAN designs, and legacy 10/100 infrastructure requiring a physical layer capable of copper and 100BASE-X media support. System designers should pair it with a compatible Ethernet MAC or network controller, validate media magnetics or fiber components against the selected 10BASE-T or 100BASE-X topology, and confirm that the controller interface matches the DP83843 configuration.
A key implementation consideration is that Ethernet PHY designs are sensitive to power integrity, clock quality, controlled-impedance routing, and media-interface layout. Place all required bypass capacitors close to their associated supply pins, provide a continuous return path beneath high-speed signal routes, and keep the PHY, magnetics, and connector placement coordinated to minimize differential-impedance discontinuities and coupling into sensitive analog circuitry.
This product overview consolidates the manufacturer-supported protocol capabilities, package information, sourcing guidance, comparison criteria, and practical PCB guidance needed to evaluate the DP83843BVJE/NOPB for a 10/100-Mbps Ethernet physical-layer design.

التطبيقات النموذجية
DP83843BVJE/NOPB مناسب لـ 6 التطبيقs: Industrial 10/100 Ethernet Equipment, 100BASE-X Fiber Network Interface, Legacy 10BASE-T LAN Equipment, AUI-Connected Network Equipment, Embedded Controller Ethernet Connectivity, Communications and Network Interface Cards.
Industrial 10/100 Ethernet Equipment
The DP83843BVJE/NOPB fits industrial network-interface equipment requiring both 10BASE-T and 100BASE-X capability in one 10/100-Mbps PHY family. The manufacturer identifies integrated PMD sublayers, fiber support, and AUI support, allowing the design team to select an appropriate physical-media path without changing the Ethernet speed class. The 80-pin QFP (NNC) format provides dedicated external connectivity, but its 14 x 14 mm footprint and 0 C to 70 C rating must be accommodated during enclosure and thermal planning.
موصى به
100BASE-X Fiber Network Interface
The DP83843BVJE/NOPB is appropriate for a 100BASE-X network interface because Texas Instruments explicitly lists 100BASE-X and fiber support for the device. It provides the 100-Mbps physical-layer function needed between an Ethernet controller and the selected fiber-media implementation. Designers should use the manufacturer configuration, pin-description, and timing information to establish the required operating mode, then validate the fiber-side components and signal path against the complete interface specification.
موصى به
Legacy 10BASE-T LAN Equipment
The DP83843BVJE/NOPB supports 10BASE-T operation for legacy 10-Mbps Ethernet LANs while remaining compatible with 100-Mbps operation through its broader 10/100-Mbps physical-layer capability. This makes it useful in industrial controllers, communications equipment, and embedded systems that must interoperate with both 10-Mbps and 100-Mbps network segments. The controller, clocking, isolation, magnetics, and connector implementation must be validated as one complete Ethernet physical-layer design.
موصى به
AUI-Connected Network Equipment
The listed AUI support gives the DP83843BVJE/NOPB a distinct role in legacy or specialized Ethernet equipment requiring an Attachment Unit Interface path. It can fit communications and industrial systems that combine a 10/100-Mbps controller with AUI-connected physical media rather than relying only on a conventional copper magnetics interface. Because AUI implementations can involve significant signal-routing and transition requirements, engineers should follow the manufacturer configuration guidance and verify cable, connector, timing, and media compatibility.
موصى به
Embedded Controller Ethernet Connectivity
The DP83843BVJE/NOPB can serve as the Ethernet physical layer beside an embedded processor or communications controller that requires 10/100-Mbps connectivity. Its integrated PMD sublayers and support for 10BASE-T, 100BASE-X, and AUI provide multiple physical-interface options in one device family. The implementation must account for the 80-QFP land pattern, clock requirements, supply bypassing, controller timing, and the exact media components needed to create a compliant Ethernet connection.
موصى به
Communications and Network Interface Cards
The DP83843BVJE/NOPB is suitable for communications equipment and network-interface card designs requiring a dedicated 10/100 Ethernet PHY rather than an integrated controller PHY. Its 80-pin QFP (NNC) package exposes the extensive set of connections expected in a multifunction physical-layer device. Board designers should coordinate connector placement, media components, clock routing, isolation boundaries, and power distribution so that the PHY can operate across the intended 10/100-Mbps environment.

ملاحظات التصميم
Place the DP83843BVJE/NOPB close to the Ethernet media interface and route the media signals as controlled-impedance differential pairs where the selected physical medium requires them. Keep connector, magnetics, and isolation components away from unrelated switching nodes. Use a continuous reference plane beneath the media routes and avoid test pads or unused stubs that create impedance discontinuities.
Follow the manufacturer pin-description table to identify every supply connection and place the required bypass capacitors immediately beside their associated PHY pins. Provide low-impedance power and ground distribution so switching current from other board areas does not disturb the Ethernet transceiver. Verify startup, supply sequencing, and operating ranges against the exact DP83843BVJE/NOPB datasheet rather than assigning pins solely by function grouping.
The 80-pin QFP (NNC) package makes careful pin assignment essential. Arrange the layout so clock inputs, control signals, and each supported media path have short, predictable routes. Keep sensitive clock and analog-related nodes away from Ethernet media pairs where practical, and validate the footprint against the official NNC drawing before releasing Gerber files for the 14 x 14 mm package.
Do not treat DP83843BVJE, DP83843BVJE-3A, and DP83843BVJE/NOPB as interchangeable solely because they share the DP83843 family name. Confirm the exact ordering suffix, pin function table, clock configuration, media support, operating-temperature grade, and RoHS position. Also verify whether the board uses 10BASE-T, 100BASE-X, or AUI, because each path changes the external media components and layout requirements.
معلومات الامتثال
The substitution comparison identifies DP83843BVJE/NOPB as RoHS-compliant. RoHS is not an automotive qualification, so AEC-Q100 is marked not applicable. Other environmental and material compliance attributes require confirmation from the manufacturer product documentation.
