DP83849IFVS/NOPB - Dual 10/100 Ethernet PHY | Texas Instruments
MPN: DP83849IFVS/NOPB ✓ NakahandaDP83849IFVS/NOPB Ulas
An Ethernet physical-layer transceiver, commonly called an Ethernet PHY, converts logical data from an Ethernet controller into signals that can traverse copper cabling or fiber media. It also receives analog signaling from the network and converts it into digital data for the controller. As a dual-port PHY, the DP83849IFVS/NOPB can manage two independent 10/100 Mb/s Ethernet links while sharing one host-facing interface.
The device is differentiated by its fiber-support capability, industrial-temperature range, and flexible port switching. These characteristics allow a single physical-layer device to serve copper and fiber-facing equipment designs where separate PHY solutions would otherwise be required. Its two-channel architecture also supports dual-port networking equipment with a more compact component footprint than two unrelated PHYs.
The DP83849 family is positioned between a media-access controller and the physical network medium. A controller handles frame processing, addressing, and protocol activity, while the PHY performs electrical signaling, line coding, link negotiation, and physical-layer status reporting. Separating these functions lets manufacturers reuse a host controller while selecting the PHY appropriate for the required media, temperature range, and port arrangement.
Typical uses include industrial Ethernet switches, factory automation equipment, embedded gateways, serial-to-Ethernet systems, optical-network interfaces, and dual-port industrial controllers. Fiber support is particularly useful when equipment must communicate across electrically noisy factory environments or over longer cable runs. The industrial temperature rating also makes the device suitable for equipment operating outside typical commercial environmental conditions.
PCB implementation must preserve the pin assignments and high-speed signal-routing conditions defined by the manufacturer. Keep the Ethernet differential pairs routed with continuous reference planes and controlled impedance, place termination and magnetic-component footprints where specified, and isolate analog, digital, and power-supply return currents. Confirm every pin connection and supply requirement against the manufacturer datasheet before releasing the PCB.
This product record combines the official device description, package and environmental specifications, supported interface roles, practical industrial-networking applications, and verified drop-in references. It is intended to accelerate component selection while preserving the engineering checks required for a reliable Ethernet physical-layer implementation.

Tipikal na mga Gamit
DP83849IFVS/NOPB ay nararapat para sa 6 aplikasyons: Industrial Ethernet Switches, Factory Automation Controllers, Embedded Network Gateways, Fiber-Connected Network Equipment, Serial-to-Ethernet Equipment, Industrial Monitoring Systems.
Industrial Ethernet Switches
The DP83849IFVS/NOPB fits industrial switching equipment requiring two 10/100 Mb/s copper-oriented ports with extended environmental operation. Its -40C to 85C industrial-temperature range is more suitable for factory-floor equipment than a commercial-temperature PHY, while the flexible port-switching capability supports shared media-interface configurations. The device operates from 3 V to 3.6 V and fits an 80-pin TQFP footprint. Design the board around the manufacturer’s recommended magnetics, termination, decoupling, and differential-routing guidance.

Factory Automation Controllers
The DP83849IFVS/NOPB provides dual 10/100 Mb/s physical-layer connectivity for PLCs, industrial controllers, and machine interfaces that must operate across a -40C to 85C ambient range. Flexible port switching can simplify shared copper and fiber-facing arrangements, while dual transmit and receive channels support two network links from one device. Its 3 V to 3.6 V operating range integrates with conventional 3.3 V equipment while separating physical signaling from the controller’s protocol processing.
Inirekomenda
Embedded Network Gateways
The DP83849IFVS/NOPB is suitable for embedded gateways that need two independent 10/100 Mb/s Ethernet physical layers in a 12 mm by 12 mm, 80-pin TQFP package. The industrial-temperature rating supports equipment deployed in enclosures with elevated internal temperatures, and fiber support allows copper and optical media options to share a product platform. Engineers should verify register defaults, strap configuration, media support, and isolation requirements before fixing the network architecture.
Inirekomenda
Fiber-Connected Network Equipment
The DP83849IFVS/NOPB supports fiber-facing network equipment because the DP83849IF family includes fiber support alongside its two 10/100 Mb/s ports. This feature is useful in industrial optical links, remote monitoring stations, and transport systems where copper cabling would be vulnerable to electromagnetic interference. The PHY’s -40C to 85C operating range also covers many industrial environments. The external optical-interface implementation and component values must follow the manufacturer’s reference design rather than a generic Ethernet layout.
Inirekomenda
Serial-to-Ethernet Equipment
The DP83849IFVS/NOPB can provide the Ethernet physical layer in industrial serial-to-Ethernet bridges, where a host controller handles protocol conversion while the PHY performs copper signaling and link negotiation. Two ports can support upstream and downstream network connections, and the -40C to 85C rating suits deployed industrial equipment. Keep the PHY-to-controller interface, reset behavior, and clocking consistent with the manufacturer reference design, especially where cable-magnetics isolation affects board placement.
Inirekomenda
Industrial Monitoring Systems
The DP83849IFVS/NOPB is appropriate for monitoring controllers, remote sensor gateways, and condition-monitoring equipment requiring Ethernet connectivity over copper or fiber. Its dual 10/100 Mb/s capability can connect a local network segment and an uplink, while the industrial temperature range supports harsh installations. For systems combining low-level sensing, high-speed digital processing, and Ethernet communication, maintain the separation recommended by the manufacturer so switching and digital circuitry do not degrade the physical-layer signals.

Talaan ng Disenyo
Route the Ethernet differential pairs as controlled-impedance, tightly coupled traces with a continuous reference plane. Keep PHY-to-magnetics paths short, avoid stubs, and match differential pair length according to the manufacturer layout guidance. Place magnetic components and termination networks close to the relevant PHY pins, while keeping switching regulators, crystals, and high-speed digital clocks away from sensitive analog and copper-interface nodes.
Use the manufacturer’s pin-description table and application schematic when assigning every signal in the 80-pin TQFP (PFC) footprint. A generic TQFP symbol may not represent the fiber, strap, clock, reset, interrupt, or power pins correctly. Review supply connections, decoupling placement, grounding, and exposed thermal requirements before releasing artwork, and compare the assembled board against the evaluation-kit layout where practical.
Plan the 3 V to 3.6 V supply network so the PHY receives stable power during Ethernet link startup, reset, and cable insertion events. Follow the manufacturer’s recommended bypass capacitance and placement values, and separate sensitive analog or interface returns from noisy digital and switching currents where the reference design permits it. Verify power sequencing and reset timing against the host controller interface to avoid unintended transceiver states.
Do not treat a shared 80-pin TQFP footprint as proof of a functional drop-in replacement. The DP83849IVS/NOPB, DP83849CVS, and DP83849IDVS have documented family relationships, but media support, temperature grade, strap behavior, and register configuration may differ. For each substitution, compare the complete manufacturer pin list, electrical limits, media interface, and application circuit before approving production use.
