DP83TG720RWRHARQ1 - 1000BASE-T1 Automotive Ethernet PHY | TI
料号： DP83TG720RWRHARQ1 ✓ 量产中DP83TG720RWRHARQ1 概述
A 1000BASE-T1 PHY is an Ethernet transceiver that converts digital data from a MAC into electrical signals suitable for a single twisted pair and converts incoming cable signals back into digital MAC data. Within the network hierarchy, the DP83TG720R-Q1 family belongs to the 1000BASE-T1 automotive Ethernet PHY category, where it bridges an RGMII-capable host processor with a 1000BASE-T1 physical network.
The device complies with IEEE 802.3bp and applicable Open Alliance EMC and interoperability specifications for automotive Ethernet links. Its RGMII interface allows connection to a compatible Ethernet MAC, while its single-pair cable support addresses the bandwidth and wiring requirements of next-generation vehicle networks. The manufacturer also states that the DP83TG720 family is front-print compatible with TI's 100BASE-T1 PHY, supporting design scalability where a single board layout can accommodate both speeds.
The DP83TG720 architecture consolidates the functions required for an automotive Ethernet physical layer, including transmit and receive signal handling, interface to the MAC, and support for automotive cable environments. The 36-VQFN package is designed for surface-mount assembly, but exposed-pad layout, thermal performance, and multilayer-board construction must be evaluated as part of the complete design rather than inferred from the package outline alone.
Typical uses include vehicle Ethernet gateways, zonal controllers, advanced driver-assistance systems, infotainment platforms, automotive domain controllers, cameras, and sensors. The RGMII host interface is particularly relevant to systems in which an automotive Ethernet MAC communicates with the PHY over parallel digital signals before the PHY drives the single-pair physical network.
The primary design task is to implement the manufacturer's recommended power, decoupling, clock, RGMII, magnetic-component, cable, and high-speed layout guidance exactly. In particular, preserve the recommended layer stack and controlled-impedance geometry around RGMII and the 1000BASE-T1 pair, while observing component placement and return-path requirements that minimize radiated emissions and susceptibility problems.
This product page combines the device identity, manufacturer application information, package details, documented standards, family alternatives, comparison parameters, and practical implementation guidance into one engineering-oriented reference. It highlights which parameters are explicitly defined and directs engineers to the TI datasheet for the complete electrical tables, pin descriptions, reference circuitry, and layout checklist.

典型应用
DP83TG720RWRHARQ1 适用于 6 应用s: Automotive Zonal Controller, Vehicle Ethernet Gateway, Advanced Driver Assistance System, Automotive Camera and Sensor Node, Infotainment Backbone Interface, Scalable 100BASE-T1 and 1000BASE-T1 Platform.
Automotive Zonal Controller
The DP83TG720RWRHARQ1 fits a zonal controller that aggregates Ethernet-connected vehicle functions and presents them to a host processor through RGMII. Its 1000BASE-T1 capability supports a full-gigabit-class automotive Ethernet physical layer over a single twisted pair, reducing wiring complexity compared with conventional multi-pair Ethernet. The Q1-family identity supports automotive design planning, while TI's IEEE 802.3bp and Open Alliance statements provide the basis for EMC and interoperability validation. Final suitability depends on the controller's MAC timing, magnetic-component selection, power design, and qualification plan.
推荐
Vehicle Ethernet Gateway
A vehicle Ethernet gateway can use the DP83TG720RWRHARQ1 as the physical-layer endpoint between an Ethernet MAC and a 1000BASE-T1 network segment. Its RGMII interface supports connection to a capable MAC, while its single-pair cable capability addresses high-bandwidth vehicle backbones without requiring a conventional multi-pair cable. IEEE 802.3bp compliance and the stated Open Alliance EMC and interoperability requirements are particularly relevant in gateway designs where multiple domains must communicate reliably under automotive electromagnetic conditions.
推荐
Advanced Driver Assistance System
The DP83TG720RWRHARQ1 is applicable to ADAS nodes that exchange high-rate sensor, camera, or radar data over an automotive Ethernet backbone. A 1000BASE-T1 physical layer provides a single-pair path between the ADAS processor's MAC and the vehicle network, while RGMII supplies the parallel host connection. The automotive Q1 family identity is appropriate for programs that require qualified supplier processes, although project approval must still include temperature, EMC, cable reach, magnetic components, firmware, and system-level network testing.
推荐
Automotive Camera and Sensor Node
A compact camera or sensor node can use the DP83TG720RWRHARQ1 when the node needs a single-pair high-speed link back to an Ethernet backbone. Connecting the PHY to a compatible MAC through RGMII separates the digital host interface from the physical cable, allowing the cable network to remain consistent across vehicle zones. The device's stated support for shielded and unshielded twisted pair permits alignment with the vehicle wiring architecture, but the power network, common-mode choke or magnetics, connector, and return-path design must be evaluated for each sensor installation.
推荐
Infotainment Backbone Interface
The DP83TG720RWRHARQ1 can connect an infotainment or cockpit computing domain to a 1000BASE-T1 vehicle backbone when the associated MAC supports RGMII. The interface supports full- and half-duplex operating modes and provides a path to higher-bandwidth vehicle networking without relying on copper Ethernet multi-pair cabling. Because infotainment systems can combine high data rates with substantial EMI sensitivity, the implementation should follow the TI reference circuit and layout guidance and include system-level EMC verification across power states and operating modes.
推荐
Scalable 100BASE-T1 and 1000BASE-T1 Platform
The DP83TG720RWRHARQ1 supports platforms intended to span 100BASE-T1 and 1000BASE-T1 network options. TI states that DP83TG720 is front-print compatible with its 100BASE-T1 PHY, allowing one printed circuit board to accommodate both speeds when surrounding circuitry and configuration support the requirement. This scalability can reduce board-development duplication across vehicle platforms, but engineers must still validate component placement, cable characteristics, EMC behavior, magnetic circuitry, and MAC configuration separately for each speed option.

设计说明
Implement RGMII and the 1000BASE-T1 pair as controlled-impedance nets on the PCB stack selected for the program. Follow the TI reference design and layout checklist for layer assignment, pair geometry, via transitions, and return paths. Keep the PHY, its supporting passive network, and the cable-side magnetic components in the same localized signal region so that the high-speed current loop remains small and does not cross unrelated power or digital return paths.
Treat the single twisted pair as a coupled differential structure rather than two independent traces. Maintain consistent spacing and length relationship across the pair, use symmetrical routing where the reference design permits, and provide a continuous ground reference beneath the pair. Validate radiated emissions and immunity in the final vehicle harness because connector transitions, chassis grounding, common-mode components, and neighboring high-current loads can dominate EMC performance outside the PHY itself.
Place all input, output, reference, and bypass components according to the manufacturer reference circuit, keeping the PHY loop and compensation paths as short as practical. Pay particular attention to the exposed-pad connection and thermal-via arrangement of the 36-VQFN package. Use the recommended land pattern and copper construction rather than deriving geometry from the 6 x 6 mm body alone, since pad dimensions and thermal-via patterns affect assembly, heat flow, and EMI behavior.
Do not approve a family-variant substitution solely because the ordering code looks similar. Verify the complete TI ordering table for temperature grade, automotive qualification, packing, exposed-pad option, and any program-specific suffix requirements. Likewise, do not treat the front-print compatibility statement as permission to omit the electrical differences between 100BASE-T1 and 1000BASE-T1 operation; check cable, magnetics, configuration, and system interoperability for the selected speed.
合规信息
The manufacturer identifies the DP83TG720R-Q1 as an automotive Ethernet PHY and the product is an automotive-grade Q1 ordering configuration, but the indexed material does not explicitly state the individual compliance fields or AEC-Q100 qualification language. These fields remain unknown pending confirmation from the manufacturer orderable-information table and material-compliance documentation.
