DP83849IDVS/NOPB - Dual-Port 10/100 Ethernet PHY | Texas Instruments
MPN: DP83849IDVS/NOPB ✓ نشطDP83849IDVS/NOPB نظرة عامة
An Ethernet PHY transceiver is the physical-layer component that converts digital Ethernet data into electrical or optical signaling and receives incoming signaling for conversion into digital data. Within the network hierarchy, this device belongs to Ethernet transceivers, physical-layer devices, interface ICs, and semiconductor components. It connects an Ethernet MAC or network processor to physical media through integrated drivers, receivers, clocking, and auto-negotiation functions.
The DP83849IDVS/NOPB supports 10/100-Mbps operation on two independent ports. Its dual-channel architecture reduces the number of separate PHY devices required in routers, industrial controllers, network switches, and test equipment. Industrial-temperature operation makes it suitable for systems expected to operate across a broad ambient range, while the 80-pin TQFP construction supports conventional surface-mount assembly and multilayer PCB routing.
Fiber support extends the design beyond copper cabling and allows optical-network-interface circuitry to be connected to the PHY where appropriate. A complete Ethernet design still requires external magnetics, isolation components, connectors or fiber transceivers, a stable supply, suitable decoupling, and a compliant signal-integrity layout. The PHY does not replace the external passive network components required at the cable or fiber interface.
Typical uses include industrial Ethernet gateways, dual-port embedded controllers, network-interface cards, optical network equipment, factory automation controllers, and communications infrastructure. The device can be especially useful where two 10/100 ports are required without allocating two separate PHY packages or where industrial temperature performance is required rather than a consumer-temperature alternative.
Design the power, clocks, magnetic components, and medium-dependent interfaces directly from the manufacturer datasheet. Keep the PHY and its support network on a controlled impedance layer, provide the required local bypass capacitors, and maintain the specified clock and reset sequencing. Confirm the complete pin assignment and exposed thermal-pad connection on the official package drawing before fabrication.
This product record combines the manufacturer’s device classification, package and temperature information, distributor listing details, and practical Ethernet design guidance. It also distinguishes true package-compatible alternatives from broader functional equivalents so engineers can assess PCB reuse, media support, and operating-temperature requirements before committing to a replacement.

التطبيقات النموذجية
DP83849IDVS/NOPB مناسب لـ 6 التطبيقs: Industrial Ethernet Gateway, Dual-Port Network Controller, Fiber-Enabled Edge Equipment, Factory Automation Controller, Optical Network Terminal, Industrial Test and Measurement Instrument.
Industrial Ethernet Gateway
The DP83849IDVS/NOPB fits an industrial gateway that must expose two 10/100-Mbps Ethernet links while operating from -40°C to +85°C. Its two transmitters and two receivers allow the gateway to connect equipment-side and network-side interfaces through one PHY package. The 80-pin PFC TQFP also provides separate routing channels for clocks, control signals, and copper or fiber support. External magnetics, isolation, bypass capacitors, and controlled-impedance routing remain necessary. Compared with two separate single-port PHYs, the dual-channel implementation can simplify board partitioning, but each medium interface still requires its own passive network and protection design.

Dual-Port Network Controller
Use the DP83849IDVS/NOPB when an embedded network controller requires two 10/100-Mbps physical-layer ports for routing, bridging, or equipment aggregation. Its dual-channel architecture supplies separate drivers and receivers, while the industrial-temperature specification supports installation in machinery and communications equipment. The device operates alongside a MAC or network processor rather than replacing Ethernet frame processing. Board designers should reserve space for two isolation networks, provision low-impedance clock routing, and use the datasheet reference layout to minimize radiated emissions and maintain compliant link performance.
موصى به
Fiber-Enabled Edge Equipment
The DP83849IDVS/NOPB is appropriate for edge equipment that includes fiber support alongside copper Ethernet connectivity. Its manufacturer description explicitly identifies fiber support, allowing system designers to evaluate the PHY for optical-network-interface paths without moving immediately to a different PHY family. Implementation still requires the correct external optical and isolation circuitry for the selected medium. The 80-pin TQFP package provides the pin density needed for dual-port copper and fiber-related functions, but signal integrity depends on controlled-impedance layout, proper supply decoupling, and strict separation between sensitive analog and high-speed digital paths.
موصى به
Factory Automation Controller
The DP83849IDVS/NOPB supports factory automation controllers that connect sensors, programmable logic controllers, drives, or supervisory systems to an Ethernet backbone. Its -40°C to +85°C operating range covers environments beyond consumer-temperature operation, while dual 10/100-Mbps ports can support a local service connection and an upstream plant network. For robust industrial operation, follow the manufacturer’s grounding and isolation recommendations, provide clean supply rails, and verify magnetics and connector choices for the required cable lengths. Isolation and surge-protection components are separate from the PHY and must be selected for the actual port environment.
موصى به
Optical Network Terminal
In an optical network terminal, the DP83849IDVS/NOPB can serve as the Ethernet physical-layer device in designs that combine copper management access with optical network connectivity. Its two transmitters, two receivers, 10/100-Mbps capability, and fiber support make it relevant to dual-medium equipment. The PHY should be paired with an appropriate media converter or optical interface rather than driving fiber directly. Layout quality is critical: keep the high-speed nets referenced to a continuous ground plane, follow the manufacturer’s recommended spacing and termination, and validate eye diagrams, return loss, and radiated emissions before production release.
موصى به
Industrial Test and Measurement Instrument
The DP83849IDVS/NOPB can support test and measurement instruments that need two Ethernet connections for instrument control, synchronization, or network management. Its dual-port arrangement reduces the need for separate PHY devices, and its industrial-temperature range suits equipment deployed outside controlled laboratory conditions. Designers should treat the PHY’s 3.3-V-class implementation only after confirming the exact supply limits in the manufacturer datasheet. Stable clocks, deliberate enable sequencing, local high-frequency bypass, and isolated copper interfaces help preserve measurement accuracy and network reliability in racks containing switching power supplies and long external cables.

ملاحظات التصميم
Construct the PCB footprint and signal assignment from the official 80-pin PFC package drawing and pin-description table. Reserve continuous ground-plane references beneath the PHY and its high-speed nets, preserve the manufacturer’s recommended component spacing, and route clocks and data interfaces away from switching nodes. Do not infer exposed-pad connectivity or reserved-pin behavior from a generic TQFP drawing because incorrect connections can affect startup, ground integrity, and EMI performance.
Place the required input and output bypass capacitors directly at their associated supply pins, using the shortest possible ground-return paths. Confirm the target-device voltage range, current limits, sequencing requirements, and power-consumption values in the manufacturer datasheet before selecting regulators or capacitor ratings. Check startup current and inrush behavior across both Ethernet ports so the supply remains within limits when both interfaces enable together.
Treat each copper Ethernet interface as a high-speed differential structure even though the advertised data rate is 10/100 Mbps. Use the reference layer stack-up and via geometry recommended for the required impedance, maintain pair-length balance where specified, and terminate the interface according to the manufacturer’s application guidance. Verify radiated emissions and immunity with the final magnetics, connectors, enclosure, and cables rather than relying only on PHY simulation.
Do not substitute DP83849IFVS/NOPB or DP83849IVS/NOPB solely because the package pin count matches. Compare the complete pin names, power domains, reset behavior, clock requirements, media support, temperature grade, and electrical limits. A shared 80-TQFP outline reduces mechanical rework, but PCB reuse is only valid when every connected net has the same function and operating limits in the replacement device.
