Product details
Overview
DP83867IRRGZR from Texas Instruments is an industrial-grade 10/100/1000BASE-T Ethernet PHY transceiver in a 48-pin VQFN package, supporting RGMII MAC interface, delivering ultra-low RGMII latency (TX < 90 ns, RX < 290 ns), 457 mW full-power consumption, and 8 kV IEC 61000-4-2 ESD protection on MDI pins. It enables robust wired connectivity in motor drives and industrial automation systems requiring IEEE 1588 time stamping and TSN compliance.
For engineers reviewing the DP83867IRRGZR datasheet, DP83867IRRGZR pinout, DP83867IRRGZR application, or DP83867IRRGZR equivalent, this page delivers verified technical context, real-world interface timing constraints, industrial temperature operation (–40°C to +85°C), RGMII delay programmability, and precise power rail requirements for reliable system integration.
Technical Context
The DP83867IRRGZR implements a fully integrated PMD sublayer compliant with IEEE 802.3 10BASE-Te, 100BASE-TX, and 1000BASE-T standards, with differential MDI outputs (TD_P_A/MDI_A through TD_M_D/MDI_D) supporting full-duplex twisted-pair signaling. Its RGMII interface operates at 125 MHz GTX_CLK with programmable 16-mode RX/TX delay compensation and Start of Frame detection for IEEE 1588 timestamp alignment.
It features three independent analog supply domains (VDDA2P5 = 2.5 V ±5%, VDDA1P8 = 1.8 V ±5%, VDD1P0 = 1.0 V +15.5%/–5%) and configurable I/O voltage (1.8 V / 2.5 V / 3.3 V), enabling low-noise signal integrity and flexible host interface compatibility. Wake-on-LAN packet detection and JTAG support enable remote management and debug in embedded industrial deployments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate Support | 10/100/1000 Mbps full-duplex Ethernet per IEEE 802.3 standards - enables single-port gigabit LAN in space-constrained industrial controllers. |
| RGMII Latency | TX < 90 ns, RX < 290 ns - minimizes end-to-end network stack delay critical for Time-Sensitive Networking (TSN) applications. |
| ESD Protection | ±8 kV IEC 61000-4-2 contact discharge on MDI pins - ensures field reliability in electrically noisy factory environments. |
| Power Consumption | 457 mW at 1000BASE-T (RGZ package) - reduces thermal load and simplifies heatsinking in sealed enclosures. |
| Operating Temperature | –40°C to +85°C - qualified for industrial embedded computing and motor drive control cabinets without derating. |
| Clock Outputs | 25 MHz or 125 MHz synchronized CLK_OUT - provides traceable reference for MAC timing or external clock distribution. |
| I/O Voltage Options | Configurable 1.8 V / 2.5 V / 3.3 V - matches common FPGA/SoC I/O banks without level-shifting circuitry. |
Pinout & Package
DP83867IRRGZR uses a 48-pin VQFN (RGZ) package, 7 mm × 7 mm, with exposed thermal pad (DAP = GND). Pin functions are validated per TI SNLS484J Rev JUNE 2026, Figure 5-2 and Table 5-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TD_P_A / TD_M_A TD_P_B / TD_M_B TD_P_C / TD_M_C TD_P_D / TD_M_D | Differential MDI transmit/receive pairs | Direct connection to Ethernet magnetics; supports full-duplex 1000BASE-T over Cat5e/6 cable without external line drivers. |
| RX_D0–RX_D3 TX_D0–TX_D3 RX_CLK / GTX_CLK | RGMII data and clock signals | 4-bit bidirectional data bus with source-synchronous 125 MHz clocks - requires matched trace lengths ≤100 ps skew for setup/hold compliance. |
| MDC / MDIO | IEEE 802.3 serial management interface | 25 MHz max clock rate; MDIO requires external 2.2 kΩ pull-up to VDDIO for open-drain operation and register configuration. |
| INT/PWDN | Interrupt output or power-down input | Configurable via register: as open-drain interrupt (active-low, 2.2 kΩ pull-up to VDDIO) or hardware power-down trigger (low-active). |
| RESET_N | Asynchronous active-low reset | Minimum 1 µs pulse width required; resets all internal registers to default state and reinitializes PHY link negotiation logic. |
| XI / XO | 25 MHz crystal oscillator interface | Accepts 25 MHz ±50 ppm crystal; XO must be left floating when using external oscillator - no internal PLL multiplication. |
Key Features
| Feature | Design Value |
|---|---|
| 16-mode RGMII delay tuning | Programmable RX/TX delay compensates for PCB trace length mismatch - eliminates need for external delay lines or FPGA-based deskew logic. |
| Integrated MDI termination | On-chip 50 Ω differential termination resistors reduce BOM count and improve impedance matching stability across temperature and voltage. |
| IEEE 1588 Start-of-Frame detect | Hardware-accelerated detection of Ethernet frame boundaries - enables precise hardware timestamping without CPU overhead or software jitter. |
| RJ45 mirror mode | Swaps MDI polarity to correct reversed cable wiring - avoids board respin during prototype validation or field deployment. |
| Cable diagnostics | Open/short detection on all four MDI pairs with distance-to-fault estimation - replaces external TDR tools for in-system cable health monitoring. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Ethernet PHY applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DP83867IRPAP | 64-pin HTQFP package; supports MII/GMII/RGMII (vs. RGZ's RGMII-only); higher thermal resistance (RθJA = 30.9°C/W vs. 30.8°C/W) | Required when MII/GMII interface or additional GPIOs needed; less suitable for ultra-compact designs | Select DP83867IRPAP only if multi-interface flexibility or larger PCB footprint is acceptable. |
| Marvell 88E1512 | Supports SGMII and RGMII; lower ESD rating (±4 kV HBM on MDI); no integrated 25/125 MHz CLK_OUT | Used in cost-sensitive telecom infrastructure where SGMII backplane links dominate over RGMII-to-FPGA | Choose Marvell 88E1512 only when SGMII compatibility or dual-MAC port aggregation is required. |
Compared with DP83867IRRGZR, DP83867IRPAP offers broader MAC interface support but larger size and higher power, while Marvell 88E1512 trades industrial ESD robustness and integrated clocking for SGMII capability - making DP83867IRRGZR optimal for compact, noise-immune RGMII-based industrial edge nodes.

FAQ
What is the operating temperature range for DP83867IRRGZR?
The DP83867IRRGZR is rated for industrial operation from –40°C to +85°C ambient temperature. This range is validated per TI SNLS484J Rev JUNE 2026 and applies to full functionality including 1000BASE-T link establishment, RGMII timing margins, and ESD protection performance. Junction temperature must remain ≤105°C under continuous operation.
Does DP83867IRRGZR support IEEE 1588 hardware timestamping?
Yes, DP83867IRRGZR provides dedicated Start of Frame Detect logic that identifies the precise arrival of the first octet of an Ethernet frame. This hardware signal enables external timestamping units or FPGA logic to capture sub-microsecond-accurate timestamps - a core requirement for IEEE 1588 Precision Time Protocol implementation in TSN-compliant systems.
Can DP83867IRRGZR operate with a 1.8 V I/O supply?
Yes, DP83867IRRGZR supports configurable VDDIO at 1.8 V (±5%), 2.5 V (±5%), or 3.3 V (±5%). When set to 1.8 V, its RGMII I/O meets VIH ≥ 1.26 V and VOL ≤ 0.2 V per specification, ensuring interoperability with 1.8 V FPGA or SoC interfaces without level shifters - confirmed in Section 6.5 Electrical Characteristics of the datasheet.
What is the purpose of the RBIAS pin on DP83867IRRGZR?
The RBIAS pin on DP83867IRRGZR connects to an external 11 kΩ ±1% resistor to ground, setting internal bias currents for the analog front-end. This resistor directly calibrates MDI driver amplitude and receiver sensitivity - omitting it or using incorrect tolerance causes noncompliant 1000BASE-T output voltage (VOD-1000) and may fail IEEE conformance testing.
How does DP83867IRRGZR handle cable faults?
DP83867IRRGZR integrates cable diagnostic functionality that performs time-domain reflectometry (TDR)-like analysis on all four MDI pairs. It reports open/short conditions and estimates distance-to-fault up to 150 meters - accessible via MDIO register reads - eliminating need for external test equipment during field commissioning or preventive maintenance of industrial Ethernet drops.
