DP83848IVV/NOPB - 10/100 Ethernet PHY | Texas Instruments
MPN: DP83848IVV/NOPB ✓ Hoạt độngDP83848IVV/NOPB Tóm tắt
An Ethernet PHY is the physical-layer component that converts digital MAC data into signals suitable for twisted-pair cabling and recovers signals presented by the cable. It belongs to the Ethernet transceiver hierarchy, where a PHY connects a network controller or processor to the physical copper medium. A 10/100 PHY supports both 10 Mb/s and 100 Mb/s operation, allowing a single physical interface to accommodate legacy and Fast Ethernet links.
The DP83848IVV/NOPB combines Ethernet transceiver functionality with SNI and JTAG support. SNI provides a simplified network interface for applications that do not require the full register set of a conventional media-access controller. JTAG support assists board-level configuration, boundary scanning, and manufacturing test. The industrial temperature qualification makes the device suitable for equipment expected to operate across a broad commercial temperature range.
The manufacturer describes the DP83848I family as a robust Ethernet PHY transceiver intended for industrial applications. Its SNI and JTAG features help reduce external interface complexity while preserving access to PHY configuration and production-test functions. The 48-pin LQFP (PT) package provides 48 external connections and is suited to conventional surface-mount PCB assembly rather than the smallest possible embedded designs.
Typical uses include industrial Ethernet controllers, factory automation equipment, embedded control systems, network interface adapters, and communications equipment requiring a single copper-network port. The part is particularly appropriate where a system needs 10/100 Mb/s compatibility, industrial-temperature operation, and a simple PHY interface without moving to a newer multi-gigabit interface architecture.
PCB design should follow the pin-description table and reference layout in the manufacturer documentation. Maintain short, continuous return paths beneath the digital interface and provide the required local bypass capacitors near the device. For magnetics-coupled ports, follow the specified separation and grounding guidance to reduce common-mode noise and maintain reliable link performance.
This page combines the exact manufacturer order information, package and temperature details, verified drop-in candidates, interface-selection guidance, and practical PCB considerations into a design-focused reference for engineers evaluating the DP83848IVV/NOPB Ethernet PHY.

Ứng dụng tiêu biểu
DP83848IVV/NOPB phù hợp cho 6 Áp dụngs: Industrial Automation Controller, Factory Automation Gateway, Embedded Network Interface Card, Networked Measurement Instrument, Motor Control and PLC Communication, Industrial IoT Sensor Gateway.
Industrial Automation Controller
The DP83848IVV/NOPB fits industrial automation controllers that require a reliable 10/100 Mb/s copper Ethernet connection. Its -40°C to 85°C industrial temperature range, 3 V to 3.6 V supply range, and 48-pin LQFP package support robust embedded-control hardware rather than a consumer Ethernet connector design. The integrated 1/1 transceiver supports both 10 Mb/s and 100 Mb/s links, while SNI can simplify the controller-to-PHY interface when full media-access-controller management is unnecessary. JTAG also assists production configuration and boundary-scan testing. Place the PHY close to the connector and network magnetics, keep return paths continuous, and validate isolation, grounding, and conducted-emissions requirements in the completed industrial enclosure.

Factory Automation Gateway
A factory automation gateway can use the DP83848IVV/NOPB when it needs one copper-network port with 10 Mb/s and 100 Mb/s compatibility. The industrial temperature rating covers equipment expected to operate from -40°C to 85°C, while the IEEE 802.3u designation identifies compatibility with Fast Ethernet operation. SNI support is useful for gateways with limited PHY-management overhead, and JTAG provides a manufacturing diagnostic path. The 7 mm × 7 mm LQFP footprint remains practical for industrial board layouts with adequate routing space. Design the printed circuit board with a continuous ground reference, short supply connections, proper bypass capacitors, and copper isolation between the digital PHY domain and the network-transformer side to preserve signal integrity and electromagnetic performance.

Embedded Network Interface Card
The DP83848IVV/NOPB is appropriate for embedded network interface cards requiring a conventional 10/100 Mb/s Ethernet PHY rather than a multi-gigabit interface. A 3 V to 3.6 V operating range fits a 3.3 V embedded system, and the LQFP package exposes straightforward assembly and inspection for industrial production. The PHY can operate with SNI when the host controller requires a reduced register interface, or with JTAG when production test and boundary scanning are important. Because this is a copper twisted-pair application, the complete board must account for the line transformer or other magnetics, connector mechanics, isolation requirements, and enclosure grounding. Use the manufacturer reference layout to establish component placement and keep sensitive analog and power routing away from fast digital interfaces.

Networked Measurement Instrument
DP83848IVV/NOPB can support a networked measurement instrument that transfers data over a 10/100 Mb/s Ethernet port while operating in an industrial-temperature environment. The PHY provides a defined physical-layer interface between the instrument controller and a copper Ethernet connection, and its JTAG support can complement manufacturing diagnostics. SNI may reduce firmware complexity when the instrument does not need extensive PHY status polling. The 48-pin LQFP package is larger than the smallest available Ethernet PHYs, but it offers ample routing access and is straightforward to assemble with conventional leaded-pitch tooling. Designers should separate the network-side copper and magnetics from precision measurement circuitry, maintain a single low-impedance ground reference under the IC, and validate conducted and radiated emissions before industrial certification.

Motor Control and PLC Communication
The DP83848IVV/NOPB is well suited to motor-control equipment and PLC communication modules requiring an industrial 10/100 Mb/s Ethernet interface. Its -40°C to 85°C operating range supports temperature-challenged control cabinets, while SNI and JTAG provide useful options for simplified host connectivity and board test. The 10/100 Mb/s capability is appropriate for supervisory Ethernet traffic, programming, diagnostics, and factory-control communications. The LQFP package requires careful decoupling at the supply pins and disciplined return-path routing between the digital interface and the analog transceiver section. Account for the network transformer, common-mode requirements, surge exposure, and protective-earth strategy in the final product rather than treating the PHY package as a complete surge-protected Ethernet front end.

Industrial IoT Sensor Gateway
An industrial IoT sensor gateway can use the DP83848IVV/NOPB to bridge a sensor controller to a 10/100 Mb/s Ethernet backbone. The device supports legacy and Fast Ethernet links, which simplifies connectivity during factory modernization where both network classes may exist. Its industrial temperature rating, SNI support, and JTAG diagnostics suit equipment that must operate reliably and be tested efficiently. The 7 mm × 7 mm LQFP package leaves room for controlled routing around the magnetics and connector. Keep the Ethernet differential pair geometry consistent, use an uninterrupted ground plane beneath the device, and place bypass capacitors at the supply pins. Validate isolation between external cabling and low-voltage sensor circuitry if the gateway operates across multiple grounding domains.

Ghi chú thiết kế
Follow the manufacturer reference layout when placing the DP83848IVV/NOPB, bypass capacitors, clock components, and network magnetics. Keep the digital interface traces short, provide an uninterrupted ground reference below the device, and preserve the specified separation between the PHY and the transformer side of the Ethernet interface. Confirm footprint dimensions against the LQFP (PT) package drawing before releasing the PCB artwork.
Place the required bypass capacitors close to their associated supply pins and verify each rail against the manufacturer electrical-characteristics table before selecting capacitors or regulators. The stated operating supply range is 3 V to 3.6 V. Check startup sequencing, tolerance, ripple, and total board-level power demand because the package-level operating range alone does not validate the complete power tree.
Treat the Ethernet network side as a controlled high-speed analog and differential-routing region. Use the recommended magnetics or alternative isolation network, maintain symmetric routing toward the connector, and observe the documented component and copper-clearance requirements. Validate return paths, impedance, radiated emissions, and immunity with the final enclosure and cabling because board-level compliance depends on the complete assembly.
Do not substitute DP83848VYB/NOPB as an unchanged-footprint replacement: its exposed-pad package changes the land pattern and thermal design. Also validate software-visible register behavior, strap settings, reset requirements, and SNI implementation on every substitution. A physically similar package is not sufficient when firmware, boot configuration, or production programming depends on the original ordering code.
