Product details
Overview
DP83867IRPAPRG4 from Texas Instruments is an industrial-grade 10/100/1000BASE-T Ethernet PHY transceiver in HTQFP-64 package, supporting MII/GMII/RGMII MAC interfaces, delivering ultra-low RGMII latency (TX < 90ns, RX < 290ns), 457mW full-power operation, and 8kV IEC 61000-4-2 ESD protection on MDI pins - deployed in motor drives and industrial factory automation systems requiring TSN compliance and IEEE 1588 timestamping.
For engineers reviewing the DP83867IRPAPRG4 datasheet, DP83867IRPAPRG4 pinout, DP83867IRPAPRG4 application, or DP83867IRPAPRG4 equivalent, key selection considerations include its triple-interface flexibility (MII/GMII/RGMII), industrial temperature range (–40°C to +85°C), programmable RGMII delays, integrated MDI termination, and synchronous 25MHz/125MHz clock output for deterministic timing in wired industrial networks.
Technical Context
The DP83867IRPAPRG4 implements a full IEEE 802.3-compliant PHY layer with integrated PMD sublayers for 10BASE-Te, 100BASE-TX, and 1000BASE-T over twisted-pair media, featuring Start of Frame Detect for IEEE 1588 hardware timestamping and RJ45 mirror mode for diagnostics. Its analog front-end includes configurable termination impedance and bias resistor (RBIAS) for precise line driver calibration.
It supports three power supply configurations (2-supply or optional 3-supply), with dedicated 1.1V (VDD1P1), 1.8V (VDDA1P8), 2.5V (VDDA2P5), and configurable I/O voltage (1.8V/2.5V/3.3V). JTAG and MDIO management interfaces enable register-level control, while Wake-on-LAN and fast link drop mode optimize system-level power management.
Key Specifications

Pinout & Package
DP83867IRPAPRG4 uses a 64-pin HTQFP (PAP) package, 12 mm × 12 mm, with exposed thermal pad (GND-connected), rated for industrial temperature operation (–40°C to +85°C). Pin functions are validated per TI SNLS484J Rev JUNE 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TX_D0–TX_D3 | Transmit Data (MII/RGMII/GMII) | 4-bit parallel data path from MAC to PHY in MII/RGMII; 8-bit in GMII (TX_D4–TX_D7 also active). |
| RX_D0–RX_D3 | Receive Data (MII/RGMII/GMII) | 4-bit parallel data path from PHY to MAC in MII/RGMII; 8-bit in GMII (RX_D4–RX_D7 also active). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Ethernet PHY applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DP83867IRRGZR | 48-pin VQFN (7 mm × 7 mm); RGMII-only interface; 457 mW power; same industrial temp grade. | Smaller footprint and lower pin count - suited for space-constrained designs where MII/GMII not required. | Select DP83867IRRGZR when board area is critical and only RGMII interface is needed; verify thermal performance with reduced RθJA (30.8°C/W vs. 30.9°C/W). |
| KSZ9031RNXIA | 48-pin QFN; 10/100/1000BASE-T; 1.8 V/3.3 V I/O; no integrated MDI termination; 1.25 V core; 520 mW typical. | Lacks TSN features and Start of Frame Detect; offers SMI management but no JTAG; lower ESD (±4 kV HBM on MDI). | Choose KSZ9031RNXIA for cost-sensitive commercial designs lacking TSN or high-ESD requirements; avoid where IEEE 1588 hardware timestamping is mandatory. |
Compared with DP83867IRPAPRG4, DP83867IRRGZR trades MII/GMII support and larger package for compactness and identical power/temperature specs, while KSZ9031RNXIA offers alternative vendor sourcing but omits TSN-enabling hardware features and robust MDI protection.

FAQ
What is the operating temperature range of the DP83867IRPAPRG4?
The DP83867IRPAPRG4 is rated for industrial operation from –40°C to +85°C ambient temperature, verified per JEDEC JESD22-A104 thermal cycling and JESD22-A108 high-temperature operating life testing. This range ensures reliable performance in motor drive cabinets, factory-floor controllers, and outdoor industrial gateways where ambient extremes occur.
Does the DP83867IRPAPRG4 support IEEE 1588 Precision Time Protocol?
Yes, the DP83867IRPAPRG4 supports IEEE 1588 hardware timestamping via its Start of Frame Detect (SFD) feature, which identifies packet boundaries with sub-microsecond accuracy. The DP83867IRPAPRG4 outputs synchronized 25 MHz or 125 MHz clocks and provides precise timing signals to the MAC layer - essential for TSN-compliant time-aware shapers and peer-to-peer transparent clocks.
Can the DP83867IRPAPRG4 operate with a 1.8 V I/O supply?
Yes, the DP83867IRPAPRG4 supports configurable I/O voltage at 1.8 V (±5%), 2.5 V (±5%), or 3.3 V (±5%) on VDDIO pins. When set to 1.8 V, VIH is 0.7 × VDDIO (≥1.26 V) and VOL is ≤0.2 V - enabling direct interface with modern low-voltage SoCs and FPGAs without external level shifters, reducing BOM and layout complexity.
What package type and pin count does the DP83867IRPAPRG4 use?
The DP83867IRPAPRG4 uses a 64-pin HTQFP (PAP) package measuring 12 mm × 12 mm with exposed thermal pad. It is distinct from the RGZ (VQFN-48) variant and supports MII, GMII, and RGMII interfaces - confirmed in TI's SNLS484J datasheet Section 4 (Device Comparison) and Section 5 (Pin Configuration).
How does the DP83867IRPAPRG4 handle ESD protection on Ethernet lines?
The DP83867IRPAPRG4 exceeds IEC 61000-4-2 Level 4 with ±8000 V contact discharge on all MDI pins (TD_P_A through TD_M_D), validated per TI's internal ESD characterization and documented in Section 6.2 of the SNLS484J datasheet. This eliminates need for external TVS diodes in most industrial deployments, simplifying magnetics design and improving system-level EMC robustness.
