DP83TC811RWRNDRQ1 Visão geral
An automotive Ethernet PHY is a physical-layer interface integrated circuit that converts digital MAC data into signals suitable for a vehicle network and converts received cable signals back into digital data. It sits between an Ethernet MAC and the twisted-pair medium, providing the physical encoding, signaling, and diagnostic functions required for reliable in-vehicle communication.
The DP83TC811R-Q1 family supports MII, RMII, and RGMII MAC interfaces through xMII flexibility. Its IEEE 802.3bw compliance targets 100BASE-T1 automotive Ethernet applications, where low-speed single-pair links are used to reduce wiring complexity while supporting vehicle data and control networks. The manufacturer also describes an integrated Diagnostic Tool Kit and a PRBS frame-generation tool compatible with internal loopbacks for transmit and receive testing without a MAC.
The package uses a wettable-flank VQFN construction, which supports inspection of solder joints in automotive electronics assemblies. Its 36-pin package and 6 mm × 6 mm footprint are intended for surface-mount designs. Exact operating voltage, current, timing, temperature, pin names, isolation, and qualification values must be confirmed from the manufacturer datasheet before schematic release or PCB layout approval.
Typical design uses include automotive Ethernet gateways, vehicle domain controllers, infotainment systems, telematics units, body controllers, sensor interfaces, and diagnostic test equipment. The MAC-side interface is selected according to the host controller requirements, while the cable-side network is designed according to the applicable 100BASE-T1 wiring and automotive Ethernet implementation constraints. The flexible MAC interface helps reduce platform duplication across different host-controller configurations.
A key design consideration is validating the complete interface chain, including MAC timing, cable termination, common-mode components, isolation strategy, connector selection, and automotive EMC requirements. This page combines verified manufacturer and distributor information with explicit data gaps; it does not infer electrical specifications that are absent from the supplied source data. Engineers should use the official DP83TC811R-Q1 datasheet and product page for final component selection and implementation.

Aplicações típicas
DP83TC811RWRNDRQ1 é adequado para 6 aplicaçãos: Automotive Ethernet Gateway, Vehicle Domain Controller, Automotive Infotainment System, Body Controller Network, Automotive Telematics Unit, Automotive Ethernet Link Test Equipment.
Automotive Ethernet Gateway
The DP83TC811RWRNDRQ1 fits an automotive Ethernet gateway where a host MAC connects to a 100BASE-T1 single-pair vehicle network. Its confirmed IEEE 802.3bw alignment, support for MII, RMII, and RGMII, and xMII flexibility allow the PHY to be evaluated against different gateway controller interfaces. The 36-pin VQFN also provides a defined 6.00 mm × 6.00 mm surface-mount footprint. Cable termination, isolation, EMC filtering, and exact timing must be validated against the official datasheet and vehicle network specification.
Recomendado
Vehicle Domain Controller
A vehicle domain controller can use the DP83TC811RWRNDRQ1 as the automotive Ethernet physical-layer interface between a host controller and a 100BASE-T1 link. The device provides the physical-layer functions required for unshielded single twisted-pair communication, while MII, RMII, and RGMII support gives designers interface options. Its confirmed wettable-flank VQFN construction is relevant to automotive inspection requirements. The controller interface must still be checked for voltage, timing, clock, and reset compatibility.
Recomendado
Automotive Infotainment System
In an infotainment platform, the DP83TC811RWRNDRQ1 can provide the 100BASE-T1 physical layer between an Ethernet-capable processor and a vehicle network. IEEE 802.3bw compliance and support for standard MII, RMII, and RGMII interfaces allow the PHY to be considered across different host-controller arrangements. The 36-pin VQFN package supports compact surface-mount implementation. System validation should include EMC behavior, cable routing, connector and isolation choices, and the manufacturer’s recommended application conditions.
Recomendado
Body Controller Network
The DP83TC811RWRNDRQ1 is applicable to body-controller networks that use 100BASE-T1 over unshielded single twisted-pair wiring. Its role is to provide the physical-layer transceiver between the controller MAC and the cable medium, with MII, RMII, and RGMII flexibility supporting different host implementations. The confirmed package is a 6.00 mm × 6.00 mm, 36-pin VQFN with wettable flanks. Before schematic approval, verify all pin functions, recommended external components, cable termination, and automotive qualification requirements.
Recomendado
Automotive Telematics Unit
A telematics unit can use the DP83TC811RWRNDRQ1 as a 100BASE-T1 automotive Ethernet interface when the host processor supports one of the confirmed xMII options. The transceiver supports the physical signaling functions needed for unshielded single twisted-pair media, while the Diagnostic Tool Kit and PRBS frame-generation capability assist bring-up and test. Designers should confirm clocking, reset behavior, cable-side components, isolation strategy, and exact timing using the official TI documentation before production implementation.
Recomendado
Automotive Ethernet Link Test Equipment
The DP83TC811RWRNDRQ1 is suitable for evaluation equipment that needs to exercise a 100BASE-T1 automotive Ethernet physical layer. Its PRBS frame-generation tool is compatible with internal loopbacks, allowing transmit and receive testing without a MAC according to the manufacturer description. The MII, RMII, and RGMII options can help configure different test-host interfaces. Test-equipment designs still need exact pinout, timing, electrical-limit, and cable-channel validation before using the device as a production measurement component.

Notas de projeto
Use the 6.00 mm × 6.00 mm, 36-pin VQFN footprint from the official TI package drawing and preserve the manufacturer’s exposed-pad and wettable-flank recommendations. Do not infer pad dimensions from the distributor package name alone. Place the PHY close to the cable-side protection and isolation components so transient energy is not propagated into the MAC or host controller, and route high-current automotive supplies and signal returns using the system’s grounding and return-path strategy.
Treat the 100BASE-T1 cable connection as a controlled high-speed physical channel even though its data rate is lower than many conventional Ethernet links. Confirm the recommended termination, common-mode components, isolation boundary, connector construction, and cable length with the official application information. Keep the cable-side network compact and controlled, and validate signal integrity with the actual harness, connector, protection devices, and automotive EMC environment rather than relying only on schematic review.
Do not substitute the DP83TC811RWRNDTQ1, DP83TC811SWRNDRQ1, or DP83TC811SWRNDTQ1 solely because their names are similar. The supplied search results identify them as related or equivalent candidates but explicitly require pinout, package, electrical, and qualification checks. Before purchase or substitution, compare the official ordering table, 36-pin mapping, exposed pad, temperature grade, MAC-side timing, cable-side behavior, and automotive qualification documentation.
Informações de conformidade
The supplied manufacturer and distributor results confirm an automotive Ethernet PHYTER product and IEEE 802.3bw application, but do not provide verified RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. Obtain current declarations from Texas Instruments before production release.
