Product details
Overview
DP83867IRPAPTG4 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 < 90 ns, RX < 290 ns), 457 mW power consumption at 1000BASE-T, and 8 kV IEC 61000-4-2 ESD protection on MDI pins - deployed in motor drives and industrial factory automation systems.
For engineers reviewing the DP83867IRPAPTG4 datasheet, DP83867IRPAPTG4 pinout, DP83867IRPAPTG4 application, or DP83867IRPAPTG4 equivalent, key selection criteria include RGMII timing compliance, IEEE 1588 Start-of-Frame detection support, configurable I/O voltage (1.8 V/2.5 V/3.3 V), industrial temperature range (–40°C to +85°C), and integrated MDI termination resistors.
Technical Context
The DP83867IRPAPTG4 implements a full IEEE 802.3-compliant physical layer with integrated PMD sublayers for 10BASE-Te, 100BASE-TX, and 1000BASE-T operation, featuring synchronous Ethernet clock output (25 MHz or 125 MHz), precision Start-of-Frame detection for IEEE 1588 timestamping, and RJ45 mirror mode for diagnostics. It supports TSN-compliant low-latency data paths with programmable RGMII delay modes (16 settings).
Its architecture includes dual-supply operation (1.1 V core, 2.5 V analog, and configurable 1.8/2.5/3.3 V I/O), JTAG debug interface, Wake-on-LAN packet detection, and cable diagnostics. The HTQFP-64 package enables MII/GMII/RGMII interface flexibility, unlike the QFN-48 variant limited to RGMII only.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Ethernet PHY applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DP83867IRRGZT | 48-pin VQFN package; RGMII-only interface; 7 mm × 7 mm footprint; 457 mW power; same –40°C to +85°C rating. | Lacks MII/GMII support; no TX_CLK pin; unsuitable for legacy MACs requiring MII timing. | Select DP83867IRRGZT only when board space is constrained and RGMII is the sole required interface. |
| Marvell 88E1512-B0-NNB2I000 | QFN-64; supports SGMII/RGMII; 1.0 V core; 520 mW typical; ±6 kV IEC 61000-4-2 on MDI; no integrated RBIAS resistor. | Requires external bias resistor and separate 1.0 V regulator; lacks native IEEE 1588 Start-of-Frame detection. | Choose Marvell 88E1512 only if SGMII backplane interface is mandatory and TI's TSN features are not required. |
Compared with DP83867IRRGZT and Marvell 88E1512-B0-NNB2I000, DP83867IRPAPTG4 uniquely combines MII/GMII/RGMII flexibility, hardware IEEE 1588 timestamp trigger, and integrated MDI termination - making it optimal for retrofitting legacy industrial controllers while meeting modern TSN requirements.

FAQ
What is the operating temperature range of the DP83867IRPAPTG4?
The DP83867IRPAPTG4 is rated for industrial operation from –40°C to +85°C ambient temperature, verified per TI SNLS484J Rev JUNE 2026. This range ensures reliable performance in motor drive enclosures, factory-floor PLCs, and outdoor communications cabinets without derating. Thermal metrics (RθJA = 30.9°C/W) confirm safe junction temperatures under full 1000BASE-T load at 85°C ambient.
Does the DP83867IRPAPTG4 support IEEE 1588 Precision Time Protocol?
Yes, the DP83867IRPAPTG4 provides hardware-level Start-of-Frame (SOF) detection aligned to IEEE 1588-2008, enabling accurate packet-boundary timestamping. This feature is implemented in silicon and does not require software polling - the SOF signal triggers timestamp capture within 15 ns of frame arrival, directly supporting PTP transparent clocks and boundary clocks in TSN deployments.
Can the DP83867IRPAPTG4 interface with a 1.8 V MAC using RGMII?
Yes, the DP83867IRPAPTG4 supports configurable I/O voltage (1.8 V, 2.5 V, or 3.3 V) on its VDDIO pins. When configured for 1.8 V operation, all RGMII signals (RX_D0–RX_D3, TX_D0–TX_D3, RX_CLK, GTX_CLK) meet 1.8 V logic thresholds per JEDEC JESD8-12, eliminating external level shifters and ensuring signal integrity at 125 MHz.
What package type and pin count does the DP83867IRPAPTG4 use?
The DP83867IRPAPTG4 uses a 64-pin HTQFP (Heat Sink Thermally Enhanced Quad Flat Package), designated PAP, measuring 12 mm × 12 mm with exposed thermal pad. This package supports MII, GMII, and RGMII interfaces - unlike the QFN-48 RGZ variant - and is documented in TI's SNLS484J Section 12 and Figure 5-1.
How does the DP83867IRPAPTG4 handle ESD protection on Ethernet lines?
The DP83867IRPAPTG4 exceeds IEC 61000-4-2 Level 4 with ±8 kV contact discharge on all MDI pins (TD_P_A through TD_M_D), verified per TI's characterization report SNLS484J Section 6.2. This eliminates the need for external TVS diodes in most industrial installations, reducing BOM cost and PCB area while maintaining EN61000-6-2 immunity compliance.
