DP83867ERGZR - 1GbE SGMII PHY | Texas Instruments
MPN: DP83867ERGZR ✓ فعالDP83867ERGZR نمای کلی
An Ethernet physical-layer transceiver, commonly called an Ethernet PHY, is the circuit that converts digital Ethernet data between a MAC or communications processor and a physical copper network. The DP83867E belongs to the Gigabit Ethernet PHY hierarchy: Ethernet transceiver > physical-layer transceiver > PHY > semiconductor. Its 10BASE-T, 100BASE-TX, and 1000BASE-T support allows one physical network interface to accommodate 10 Mb/s, 100 Mb/s, and 1 Gb/s Ethernet operation, depending on the link negotiation and connected equipment.
The verified ordering information identifies a 48-VQFN RGZ package, a 7 mm square land pattern, a 0.5 mm lead pitch, and a tape-and-reel shipping format. RGMII provides a parallel digital interface for a conventional MAC-to-PHY connection, while SGMII provides a high-speed serial interface for designs that benefit from fewer signal connections. The available comparison data also identifies cable-diagnostics, IEEE 1588 support of the stated SOF type, and JTAG 1149.1 among the notable device features.
Because the DP83867ERGZR is specified as an extended-temperature, robust, low-latency Gigabit Ethernet PHY, it is relevant to industrial automation, motor-drive systems, embedded routers, test equipment, and communications infrastructure. These systems benefit from a compact 48-pin surface-mount package and flexible RGMII or SGMII host connectivity. The exact supported link rates, electrical characteristics, clocking requirements, media-access procedures, and recommended external circuitry must be confirmed against the manufacturer datasheet before a board design is released.
A critical implementation consideration is that the PHY is part of a high-speed mixed-signal system. Designers should follow the manufacturer’s reference layout, provide the specified power and decoupling networks, and route high-speed differential pairs as controlled-impedance transmission lines. Magnetics, RJ45 circuitry, clock sources, reset timing, and the exact operating mode also require validation in the complete system rather than substitution based only on package similarity.
This page consolidates the verified manufacturer and distributor information for DP83867ERGZR, adds application and design context, distinguishes documented facts from missing technical data, and evaluates only same-package drop-in candidates that can be traced to the supplied web results. It is intended to accelerate component screening while preserving the need for datasheet-level engineering verification before procurement or PCB release.

Industrial Ethernet Automation
The DP83867ERGZR fits industrial Ethernet automation equipment that needs 10/100/1000BASE-T connectivity and an extended -40 °C to 105 °C operating option. It connects an Ethernet MAC or communications processor to copper cabling through a single-port PHY with either RGMII or SGMII. The 48-pin VQFN RGZ package occupies a 7 mm by 7 mm footprint, which is useful in compact PLCs, industrial controllers, sensors, and factory gateway equipment. Designers should use the manufacturer reference layout and verify clocking, magnetics, isolation requirements, and thermal performance inside the final enclosure.
پیشنهادی
Industrial Motor Drives
DP83867ERGZR is suitable for motor-drive controllers and industrial communication equipment requiring deterministic Ethernet connectivity over copper media. The device supports 10 Mb/s, 100 Mb/s, and 1000 Mb/s, allowing a controller to use one PHY across multiple link speeds, while RGMII or SGMII provides flexibility for the host architecture. Its extended-temperature ordering information is relevant to drives installed outside climate-controlled cabinets. The PHY must be evaluated for electromagnetic immunity, cable diagnostics, isolation, grounding, and synchronization with the drive’s real-time control network before production use.

Embedded Routers and Gateways
The Texas Instruments DP83867ERGZR provides a compact Gigabit Ethernet copper interface for embedded routers, gateways, and edge equipment. A single-port PHY supporting 10, 100, and 1000 Mb/s can negotiate with endpoints and test equipment across different Ethernet speeds, while SGMII can suit a serial network processor. The 48-pin 7 mm VQFN package leaves room for memory and radio or communications hardware in dense designs. Board-level planning should include the exact RGMII/SGMII timing constraints, clock source, reference circuit, magnetic link, RJ45 interface, and power-supply sequencing.
پیشنهادی
Communication and Network Infrastructure
DP83867ERGZR can serve as the copper Ethernet access PHY in compact communications equipment, test systems, and network-interface modules. Its RGMII and SGMII interfaces allow it to connect either to a parallel MAC interface or to a serial high-speed communications processor, while the 1.0 V, 1.8 V, and 2.5 V supply options support integration with multiple host-rail arrangements. In performance-sensitive equipment, engineers must verify differential-pair impedance, return paths, jitter tolerance, clock quality, and synchronization because those parameters determine whether low latency can be maintained across the complete MAC-to-cable path.
پیشنهادی
Test and Measurement Equipment
The DP83867ERGZR is appropriate for Ethernet-enabled instruments, analyzers, and automated test equipment requiring a compact Gigabit copper interface. Supporting 10, 100, and 1000 Mb/s enables interoperability with a broad range of test endpoints, and SGMII can help integrate the PHY with high-speed processors or FPGA-based test architectures. Its extended-temperature option may assist equipment deployed in industrial environments, although the instrument enclosure determines the actual ambient requirement. Designers should use controlled-impedance routing and isolate high-speed clocks from analog magnetics and sensitive measurement circuits.
پیشنهادی
Programmable Control and Embedded Systems
DP83867ERGZR can add Gigabit Ethernet to an embedded controller, FPGA system, or programmable automation platform. The available SGMII interface is useful when a limited number of high-speed signals is preferable to a parallel RGMII connection, while the RGMII option supports controllers already designed around that parallel interface. The 48-VQFN package is compact enough for embedded boards but requires careful escape routing from the fine 0.5 mm pitch. Firmware or FPGA logic must correctly configure the PHY through its control interface, and clocking, strap settings, and power rails must match the manufacturer’s reference design.

یادداشت‌های طراحی
Use the manufacturer’s 48-pin RGZ reference layout as the controlling PCB design rather than treating every 48-VQFN alternative as automatically interchangeable. Keep the exposed-pad connection and ground via pattern consistent with the recommended land pattern, preserve short return paths beneath high-speed interfaces, and verify clearances around magnetics and clock circuitry. The supplied excerpts confirm a 7 mm body, 0.5 mm pitch, and exposed pad but do not provide the complete footprint dimensions, so those values must come from the authoritative package drawing.
Treat RGMII and SGMII as controlled high-speed interfaces. Match trace impedities to the reference design, minimize stubs, provide the required clock topology, and avoid routing PHY signals parallel to noisy switching or magnetic-component paths. SGMII can reduce interface width, but its serial link still requires compliant termination, jitter performance, and reference clocking. Verify signal and power integrity across process, voltage, and temperature corners rather than relying on nominal connection drawings.
Partition the PHY’s 1.0 V, 1.8 V, and 2.5 V supply requirements according to the selected device configuration and the manufacturer’s recommended rails. Place required bypass capacitors at their specified pins, maintain a quiet analog supply path, and keep switching-regulator layout separated from the Ethernet PHY and magnetics. The verified excerpts identify the supported voltage options but do not provide current limits, sequencing order, or capacitor values, so these must be confirmed in the datasheet before layout release.
Do not approve a substitute solely because it is labeled a 48-VQFN Gigabit Ethernet PHY. Check every numbered pin, power domain, strap state, reset behavior, clock requirement, RGMII/SGMII configuration, cable-diagnostic support, IEEE 1588 behavior, JTAG access, and exposed-pad connection. DP83867ERGZR and DP83867CSRGZR differ in the supplied temperature data, and the IR and CR options may introduce device-specific behavior. Validate firmware or FPGA register programming after any substitution.
