DP83953VUL - 13-Channel Ethernet Repeater | Texas Instruments
Teilenummer: DP83953VUL ✓ AktivDP83953VUL Übersicht
An Ethernet repeater interface controller is a physical-layer network interface device that manages signal transmission and reception across Ethernet ports. It belongs to the hierarchy of Ethernet interface controller, network interface controller, interface IC, and semiconductor. Unlike a conventional endpoint controller, the DP83953 is intended for repeater-node equipment where shared transmission media and port segmentation must be handled predictably rather than through a host-based protocol stack.
The verified device description identifies three principal capabilities: security features, internal drivers, and integrated filters. Internal drivers support the controller’s Ethernet-facing transmit function, while integrated filters reduce unwanted signal activity at the interface. The 13-channel configuration allows one device to manage multiple repeater channels, making it suitable for concentrated port-count designs. Its 4.75 V minimum and 5.25 V maximum supply limits define a conventional 5 V operating region.
The supplied 870 mA current rating is a significant design consideration because the controller may require more supply capacity than a basic low-power interface IC. A system designer should verify the device’s operating-current distribution across enabled channels, termination requirements, and thermal conditions against the manufacturer datasheet. The 160-QFP package provides a high pin count suitable for numerous repeater-port connections, clock, control, power, and status assignments.
Typical applications include industrial Ethernet repeater chassis, network-interface concentrators, factory-floor communication equipment, and embedded Ethernet switching infrastructure. The DP83953 is particularly relevant where multiple 10 Mb/s-class Ethernet segments require a physical repeater controller rather than an endpoint media-access controller. Its integrated filtering and driver functions can simplify implementation compared with a discrete repeater design.
When planning a board around the DP83953VUL, begin with the official manufacturer datasheet to confirm the complete 160-pin assignment, recommended magnetic-interface components, external filtering, decoupling, and thermal requirements. PCB designers should preserve the exposed signal paths and grounding structure required by the Ethernet interface and validate emissions, return loss, and fault isolation with representative cabling. This page consolidates verified distributor specifications, package information, sourcing links, and design cautions for faster component evaluation.

Typische Anwendungen
DP83953VUL ist geeignet für 6 Anwendungs: Industrial Ethernet Repeater Chassis, Ethernet Network Concentrator, Factory-Floor Communication Equipment, Legacy Ethernet Backplane Interface, Network Interface Concentrator, Embedded Ethernet Test Equipment.
Industrial Ethernet Repeater Chassis
The DP83953VUL fits a concentrated repeater chassis built around multiple IEEE 802.3 network segments because it provides 13 channels in one 160-BFQFP device. Its integrated drivers and filters support implementation of the physical repeater interface, while the 4.75 V to 5.25 V supply range fits conventional 5 V industrial backplanes. The verified 870 mA supply-current figure requires careful regulator sizing and thermal planning. Designers should confirm timing, termination, isolation, and fault-recovery requirements from the manufacturer datasheet before freezing the channel layout.
Empfohlen
Ethernet Network Concentrator
A network concentrator can use the DP83953VUL when the equipment must present several repeater-controlled Ethernet segments through one highly integrated controller. The device’s 13-channel arrangement reduces the number of separate repeater ICs needed in a multiport cabinet. Its internal drivers and integrated filters are central to the physical-layer implementation, while the 870 mA specified supply current must be included in the 5 V power budget. PCB routing should isolate each channel appropriately and minimize shared-impedance effects before compliance testing is attempted.
Empfohlen
Factory-Floor Communication Equipment
The DP83953VUL is applicable to factory-floor communication equipment that distributes physical-layer Ethernet segments across equipment groups or field buses. Its IEEE 802.3 repeater architecture, 13 channels, internal drivers, and integrated filters allow one device to manage numerous connections in a line-card or concentrator design. The commercial temperature grade must be checked against the actual industrial ambient range. The verified 870 mA current rating also means that the system designer should reserve adequate regulator, copper, and thermal capability for the controller and its associated Ethernet hardware.
Empfohlen
Legacy Ethernet Backplane Interface
A legacy Ethernet backplane interface can benefit from the DP83953VUL when the architecture uses a repeater controller rather than a frame-switching IC. Its 13-channel capacity supports dense interface arrangements, and the integrated driver and filter functions reduce discrete circuitry around the physical layer. The 28 mm by 28 mm 160-BFQFP package nevertheless demands careful escape routing and multilayer PCB planning. Signal-integrity validation should cover insertion loss, return loss, isolation, and behavior across the complete cable and connector set used by the target network.
Empfohlen
Network Interface Concentrator
The DP83953VUL is suitable for a dedicated interface concentrator that organizes multiple Ethernet physical-layer segments in a common enclosure. Its 13 repeater channels allow a single controller to serve a high-density port arrangement, and the integrated filters and drivers support a more controlled implementation than a collection of discrete line drivers. The part’s verified supply range of 4.75 V to 5.25 V is compatible with a regulated 5 V rail, although the listed 870 mA current requires an appropriately sized supply. Exact channel routing must follow the official pinout.
Empfohlen
Embedded Ethernet Test Equipment
Embedded Ethernet test equipment can use the DP83953VUL to create controlled repeater segments for physical-layer evaluation, fault injection, or segment isolation experiments. The 13-channel configuration permits multiple test paths under one controller, while internal drivers and filters help define the interface behavior. Because the verified data does not expose the full pin table or timing limits, engineers should treat the device as a controlled repeater element rather than assuming the behavior of a modern media-access controller. Laboratory validation should cover channel-to-channel isolation, fault recovery, and Ethernet compliance.

Designhinweise
The verified supply-current rating is 870 mA over a 4.75 V to 5.25 V input range. Estimated: at 5.25 V, the maximum input-power figure derived from those values is 4.57 W before regulator losses. Use a regulator with suitable margin, low-noise transient response, and adequate copper area; confirm the manufacturer’s worst-case operating-current conditions before assigning the supply rating.
A 160-BFQFP package requires a multilayer PCB with short, geometry-controlled Ethernet routes and a complete ground reference. Follow the official land pattern and pin table rather than a generic QFP template. Preserve the recommended spacing around transmit and receive paths, provide local decoupling at specified pins, and avoid routing unrelated digital or switching-supply nets beneath sensitive interface areas.
Do not treat the DP83953VUL as a conventional endpoint Ethernet controller merely because both support IEEE 802.3 interfaces. Its purpose is repeater control across 13 channels, with integrated drivers, filters, and security features. Do not invent pin assignments from the 160-pin count, and do not infer that a device in another package is a drop-in replacement. Confirm channel functions, termination, isolation, and fault behavior against the manufacturer datasheet.
Compliance-Informationen
The supplied distributor and search results do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. No compliance claim is inferred from the commercial temperature grade.
