DP83867ERGZT - 1GbE SGMII PHY | Texas Instruments
MPN: DP83867ERGZT ✓ Hoạt độngDP83867ERGZT Tóm tắt
An Ethernet physical-layer transceiver, or Ethernet PHY, is the component that translates between a digital MAC-side interface and analog electrical signaling on a copper Ethernet cable. The DP83867 belongs to the interface-IC hierarchy and supports the physical layer for 10 Mb/s, 100 Mb/s, and 1 Gb/s Ethernet networks. Its RGMII and SGMII interfaces allow it to connect with a host processor, FPGA, network controller, or Ethernet switch subsystem while retaining compatibility with common copper-Ethernet infrastructure.
Key features include support for all three standard copper Ethernet rates, simultaneous RGMII and SGMII interface options, a small 48-VQFN package, and a low-latency design intended for demanding communication equipment. The manufacturer describes the DP83867E as a robust, low-power, fully featured physical-layer transceiver. Its extended-temperature ordering option makes it suitable for industrial equipment and other installations where operating-temperature limits, reliability, and ESD immunity are important design considerations.
The device integrates the PMD and PCS functions needed to interface with standard 10BASE-T, 100BASE-TX, and 1000BASE-T networks. Unlike a software-only MAC, the PHY performs the physical encoding, signaling, and recovery associated with copper Ethernet. The SGMII option is particularly useful when the PHY must connect across a serial high-speed digital interface, while RGMII provides a wider parallel interface for designs using a local processor or FPGA.
Typical uses include industrial Ethernet switches, programmable logic controller gateways, factory automation controllers, network-attended test equipment, embedded systems, and rugged communications infrastructure. It is also appropriate for designs requiring a compact, single-port Gigabit Ethernet interface without the footprint of a larger multi-port transceiver.
Designers should carefully follow the manufacturer reference layout for the exposed-pad package, provide the specified power and decoupling networks, and use a qualified Ethernet transformer with the required center-tap and termination arrangement. RGMII timing is especially sensitive to trace length and clock skew, while SGMII requires controlled impedance and low-jitter routing. Magnetics selection, isolation boundaries, grounding, and surge protection must be reviewed against the target installation environment.
This product page consolidates manufacturer-supported functionality, verified distributor pricing, interface-focused comparisons, and practical Ethernet design guidance.

Ứng dụng tiêu biểu
DP83867ERGZT phù hợp cho 6 Áp dụngs: Industrial Ethernet Gateways, FPGA-Based Network Equipment, Factory Automation Controllers, Rugged Communications Equipment, Test and Measurement Instruments, Network Attached Embedded Systems.
Industrial Ethernet Gateways
The DP83867ERGZT fits industrial gateways that need one reliable copper Gigabit Ethernet connection while supporting both RGMII and SGMII host connectivity. Its extended-temperature ordering grade is useful when equipment operates beyond typical commercial conditions, and the manufacturer specifies ESD protection exceeding 8 kV under IEC 61000-4-2 direct contact. A design can place the PHY between a processor or FPGA and qualified Ethernet magnetics, using either the parallel RGMII interface or serial SGMII. The principal design checks are the exact operating-temperature range, transformer selection, isolation barrier, and Ethernet timing margins. The 48-VQFN 7 x 7 mm package also helps limit board area compared with a discrete Ethernet front end, although careful exposed-pad layout and decoupling remain essential.

FPGA-Based Network Equipment
DP83867ERGZT is appropriate for FPGA-based routers, protocol analyzers, and communication controllers requiring Gigabit Ethernet over copper. SGMII provides a compact serial interface between the PHY and FPGA, while RGMII offers a parallel path for designs that favor a simpler processor connection. The device supports 10BASE-T, 100BASE-TX, and 1000BASE-T with integrated PMD sublayers, allowing the same transceiver platform to negotiate across common Ethernet rates. Engineers should constrain SGMII or RGMII timing according to the manufacturer interface requirements and preserve the reference network layout. The verified 48-VQFN 7 x 7 mm package supports dense equipment designs, but the exposed thermal pad and high-speed nets require controlled geometry and a clean power-delivery network.

Factory Automation Controllers
The DP83867ERGZT can provide the Ethernet uplink in PLCs, machine controllers, and industrial edge equipment operating in electrically demanding environments. Extended-temperature capability and ESD immunity exceeding 8 kV under IEC 61000-4-2 direct contact make the ordering option suitable for controlled industrial deployments, subject to confirmation of the exact temperature range. The PHY terminates the copper network through qualified magnetics and connects to the controller through RGMII or SGMII. The design should include magnetics isolation, suitable center-tap termination, robust Ethernet routing, and ESD protection coordinated with the system enclosure. Its low-latency Gigabit capability supports timely communication without adopting a larger multi-port PHY, making it suitable for single-uplink machinery and remote I/O systems.

Rugged Communications Equipment
DP83867ERGZT is well suited to rugged Ethernet communications equipment requiring one high-speed copper port and an extended-temperature ordering option. The robust low-power transceiver architecture supports 10 Mb/s, 100 Mb/s, and 1 Gb/s operation, while the dual RGMII and SGMII host-interface options accommodate different controller architectures. Its specified ESD immunity helps improve interface resilience, although it does not replace external surge protection or proper chassis grounding. A rugged product should pair the PHY with qualified isolation magnetics, controlled board materials, and an enclosure designed for the installation's EMC environment. The compact 48-VQFN package saves board area, but designers must follow the reference thermal-pad layout and carefully separate Ethernet routing from sensitive analog and power sections.

Test and Measurement Instruments
The DP83867ERGZT can serve as the Gigabit Ethernet interface in oscilloscopes, logic analyzers, communication analyzers, and automated test systems that must transfer data over standard copper Ethernet. The low-latency transceiver supports 10BASE-T, 100BASE-TX, and 1000BASE-T, permitting common laboratory and factory-network infrastructure to be used without specialized fiber hardware. SGMII can reduce host-side pin count when driving an FPGA, while RGMII may simplify integration with an embedded processor. For instrumentation, the exact extended-temperature range should be checked against enclosure conditions, and the Ethernet transformer must satisfy insertion loss and return-loss requirements. Controlled impedance, short high-speed routes, solid grounding, and careful separation from analog measurement circuitry are essential.

Network Attached Embedded Systems
DP83867ERGZT gives an embedded controller a standards-compatible copper Gigabit Ethernet uplink for remote management, data logging, and service connectivity. Supporting all three common rates allows the system to operate on 10BASE-T, 100BASE-TX, or 1000BASE-T networks, while SGMII and RGMII provide flexibility in connecting the host logic. The extended-temperature ordering option is advantageous in embedded industrial enclosures, provided the complete thermal analysis keeps the device within its rated limits. Designers should implement the manufacturer-recommended decoupling, exposed-pad grounding, and Ethernet magnetics network. They must also confirm boot-time configuration, strap behavior, cable diagnostics, and the host driver's register expectations because successful physical connectivity does not guarantee identical software behavior among DP83867 ordering options.

Ghi chú thiết kế
Follow the Texas Instruments DP83867E reference layout for the 48-VQFN exposed pad, high-speed interface nets, and Ethernet analog section. Place input and output decoupling capacitors immediately at their associated supply pins, provide a low-impedance ground connection beneath the exposed pad, and maintain the manufacturer-recommended copper geometry. RGMII and SGMII routes should use continuous reference planes with controlled impedance; avoid splitting planes beneath the PHY and minimize vias on clock-sensitive nets.
Design the PHY power rails from the exact supply-voltage and sequencing requirements in the manufacturer datasheet, because those values were not included in the supplied excerpts. Use separate local decoupling branches for the digital, analog, and I/O supply domains where the reference design recommends them. Keep switching-regulator and magnetics power paths away from sensitive PHY and magnetics nodes, and verify startup behavior for the selected RGMII or SGMII configuration before releasing the PCB.
Do not treat every DP83867-family ordering option as automatically interchangeable. DP83867IRPAPT is explicitly unsuitable as a direct replacement because its pinout and register map differ and it lacks SGMII. Before substituting a candidate, verify the package footprint, exposed-pad requirements, temperature grade, supported host interface, strap configuration, power rails, register compatibility, and host-driver expectations. A matching land pattern alone does not prove functional drop-in equivalence.
Coordinate the PHY, Ethernet transformer, center-tap termination, and external protection so surge current is diverted through the intended high-current path rather than the digital ground. Maintain the manufacturer's component placement and isolation spacing. The verified ESD capability of more than 8 kV under IEC 61000-4-2 direct contact applies to the specified device conditions and does not eliminate the need for compliant magnetics, routing, enclosure bonding, and system-level surge protection.
Thông tin tuân thủ
The verified manufacturer material explicitly references IEC 61000-4-2 ESD immunity exceeding 8 kV in direct-contact conditions. RoHS, REACH, lead-free, halogen-free, and conflict-minerals declarations were not present in the supplied excerpts and are therefore recorded as unknown.
