Product details
Overview
DP83867IRPAPT from Texas Instruments is an industrial-grade 10/100/1000BASE-T Ethernet physical layer transceiver in HTQFP-64 package, supporting MII/GMII/RGMII MAC interfaces, delivering ultra-low RGMII TX latency (<90ns), 457mW full-power consumption, and ±8kV IEC 61000-4-2 ESD protection on MDI pins - deployed in motor drives and industrial factory automation systems requiring robust timing and cable diagnostics.
For engineers reviewing the DP83867IRPAPT datasheet, DP83867IRPAPT pinout, DP83867IRPAPT application, or DP83867IRPAPT equivalent, key selection considerations include its –40°C to +85°C industrial temperature rating, triple-MAC interface flexibility, IEEE 1588 Start-of-Frame detection for time-sensitive networking, and integrated MDI termination resistors eliminating external components.
Technical Context
The DP83867IRPAPT implements a full IEEE 802.3-compliant PHY with integrated PMD sublayers for 10BASE-Te, 100BASE-TX, and 1000BASE-T operation, featuring synchronous Ethernet clock output (25MHz or 125MHz) and hardware-accelerated Start-of-Frame detection for IEEE 1588 timestamping. Its RGMII interface supports 16 programmable delay modes to compensate for PCB trace skew.
It integrates configurable I/O voltage support (1.8V/2.5V/3.3V), Wake-on-LAN packet detection, RJ45 mirror mode for diagnostics, and JTAG boundary-scan test capability - all within a single-chip solution requiring only an external transformer and 25MHz crystal or oscillator.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate Support | 10/100/1000 Mbps - fully compliant with IEEE 802.3 10BASE-Te, 100BASE-TX, and 1000BASE-T standards. |
| RGMII Latency | TX <90 ns, RX <290 ns - enables deterministic real-time communication in TSN applications. |
| ESD Protection | ±8000 V IEC 61000-4-2 (direct contact) on MDI pins - eliminates need for external TVS diodes in harsh industrial environments. |
| Power Consumption | 457 mW at 1000BASE-T - optimized for thermally constrained embedded systems with industrial temperature range. |
| Interface Options | MII, GMII, and RGMII - selectable via hardware strapping; HTQFP-64 package supports all three, unlike QFN variant. |

Pinout & Package
DP83867IRPAPT is housed in a 64-pin HTQFP (PAP) package measuring 12 mm × 12 mm with exposed thermal pad. The package supports MII, GMII, and RGMII interfaces - a key differentiator from the 48-pin QFN (RGZ) variant limited to RGMII only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TX_D0–TX_D3 | Transmit Data (MII/GMII/RGMII) | 4-bit parallel data path from MAC to PHY in MII mode; synchronous to TX_CLK (2.5/25 MHz) or GTX_CLK (125 MHz). |
| RX_D0–RX_D3 | Receive Data (MII/GMII/RGMII) | 4-bit parallel data path from PHY to MAC; RX_CLK frequency scales with speed (2.5/25/125 MHz). |
| GTX_CLK | GMII/RGMII Transmit Clock | 125 MHz input from MAC - required for 1000BASE-T operation and low-latency RGMII timing. |
| MDIO / MDC | IEEE 802.3 Management Interface | Serial two-wire bus (max 25 MHz) for register configuration, link status, and PHY diagnostics. |
| TD_P_A / TD_M_A through TD_P_D / TD_M_D | Differential MDI Pairs | Four twisted-pair differential outputs/inputs (A/B/C/D) connecting directly to magnetics for 1000BASE-T signaling. |
| INT/PWDN | Interrupt / Power-Down Control | Configurable dual-function pin: active-low power-down entry or open-drain interrupt output for link/event notification. |
| XI / XO | 25 MHz Crystal Interface | Crystal input (XI) and output (XO) pins - supports 50 ppm stability requirement for IEEE 1588 synchronization. |
Key Features
| Feature | Design Value |
|---|---|
| Time-Sensitive Networking (TSN) Compliance | Hardware-accelerated IEEE 1588 Start-of-Frame detection enables sub-microsecond timestamp accuracy without CPU overhead. |
| Programmable RGMII Delay | 16 discrete RX/TX delay modes - compensates for PCB routing skew to meet RGMII setup/hold timing across temperature and voltage. |
| Integrated MDI Termination | On-die 50 Ω termination resistors per differential pair - removes 8 external 50 Ω resistors and reduces BOM count and layout area. |
| Cable Diagnostics | Real-time fault detection including open/short/cross-pair identification up to 150 m - replaces external TDR equipment in field service tools. |
| Configurable I/O Voltage | Supports 1.8 V, 2.5 V, or 3.3 V VDDIO - simplifies integration with diverse MACs (e.g., ARM Cortex-A/M series, FPGA I/O banks). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Ethernet PHY applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Marvell 88E1512 | QFN-64, supports RGMII only; lacks integrated MDI termination; 1000BASE-T power ~520 mW. | Targeted at cost-sensitive consumer gateways; not rated for industrial temperature range. | Select when footprint compatibility with QFN-64 is mandatory and MDI termination can be added externally. |
| Microchip LAN8742AI | QFN-32, 100BASE-TX only; no 1000BASE-T or TSN features; 270 mW typical power. | Suitable for legacy industrial controllers where Gigabit bandwidth is unnecessary. | Choose only for 100 Mbps-only designs requiring minimal board space and lower power than DP83867IRPAPT. |
Compared with Marvell 88E1512 and Microchip LAN8742AI, DP83867IRPAPT uniquely combines industrial temperature operation, triple-MAC interface support, integrated MDI termination, and IEEE 1588 hardware timestamping - making it the sole option for new TSN-capable industrial Ethernet designs requiring full 10/100/1000 Mbps interoperability.

FAQ
What is the operating temperature range of the DP83867IRPAPT?
The DP83867IRPAPT is rated for industrial operation from –40°C to +85°C ambient temperature. This specification is validated per JEDEC JESD22-A104 and applies to continuous operation under full 1000BASE-T load with proper thermal management. The device's thermal resistance (RθJA = 30.9°C/W) and junction-to-board parameter (ψJB = 15.5°C/W) ensure reliability in enclosed control cabinets without forced airflow. DP83867IRPAPT maintains full IEEE 802.3 compliance across this entire range.
Does DP83867IRPAPT support IEEE 1588 Precision Time Protocol?
Yes, DP83867IRPAPT provides hardware-level IEEE 1588 Start-of-Frame (SOF) detection on both transmit and receive paths, enabling sub-microsecond timestamp accuracy without software intervention. This feature is implemented in the PHY's digital block and operates independently of MAC-layer processing. The DP83867IRPAPT also delivers a synchronous 25 MHz or 125 MHz clock output referenced to the internal timing engine, critical for aligning timestamps across distributed nodes in TSN networks.
Can DP83867IRPAPT operate with a 1.8V I/O supply?
Yes, DP83867IRPAPT supports configurable VDDIO at 1.8 V (±5%), 2.5 V (±5%), or 3.3 V (±5%). When configured for 1.8 V operation, the device meets VIH ≥ 1.26 V and VOL ≤ 0.2 V specifications per its electrical characteristics table. This allows direct interfacing with low-voltage FPGAs and application processors without level-shifting circuitry - confirmed in Section 6.5 of the official datasheet (SNLS484J).
How does DP83867IRPAPT handle ESD protection on the MDI pins?
DP83867IRPAPT exceeds IEC 61000-4-2 Level 4 requirements with ±8000 V contact discharge and ±15 kV air discharge protection on all MDI pins (TD_P_A through TD_M_D). This is achieved via on-die robust clamping structures, eliminating the need for external TVS diodes in most industrial deployments. The specification is verified per IEC 61000-4-2 testing methodology and documented in Section 6.2 of the datasheet.
What MAC interfaces does DP83867IRPAPT support, and how are they selected?
DP83867IRPAPT supports MII, GMII, and RGMII interfaces - all enabled in the HTQFP-64 (PAP) package. Interface selection is determined by hardware strapping of pins CRS, COL, and RX_ER during power-up, as defined in Section 7.5.1 of the datasheet. Unlike the RGZ variant, DP83867IRPAPT's full pin count enables simultaneous access to all three interface modes, allowing design flexibility for legacy MII-based SoCs or high-speed RGMII implementations.
