Product details
Overview
DP83867IRPAPR 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 latency (TX < 90 ns, RX < 290 ns), 457 mW full-power operation, and 8 kV IEC 61000-4-2 ESD protection on MDI pins - deployed in industrial factory automation and motor drive Ethernet nodes.
For engineers reviewing the DP83867IRPAPR datasheet, DP83867IRPAPR pinout, DP83867IRPAPR application, or DP83867IRPAPR 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 DP83867IRPAPR implements a fully compliant IEEE 802.3 PHY with integrated PMD sublayers for 10BASE-Te, 100BASE-TX, and 1000BASE-T, featuring synchronous Ethernet clock output (25 MHz or 125 MHz) and hardware-accelerated Start-of-Frame detection for IEEE 1588 timestamping. Its TSN-compliant architecture supports deterministic low-latency packet forwarding.
It integrates programmable RGMII delay modes (16 settings), configurable MII/GMII/RGMII termination impedance, and Wake-on-LAN packet detection. The device uses separate analog supplies (VDDA1P8, VDDA2P5, VDD1P1) and supports 3.3 V/2.5 V/1.8 V I/O voltage scaling - enabling direct interfacing with diverse MACs without level shifters.

FAQ
What is the operating temperature range for DP83867IRPAPR?
The DP83867IRPAPR is rated for industrial operation from –40°C to +85°C ambient temperature, verified per JEDEC JESD22-A104 and qualified for continuous use in factory automation, motor drives, and outdoor industrial enclosures where thermal cycling and wide ambient swings occur. This range applies to the full functional specification including 1000BASE-T operation and RGMII timing compliance.
Does DP83867IRPAPR support IEEE 1588 timestamping?
Yes, DP83867IRPAPR provides hardware-accelerated IEEE 1588 Start-of-Frame (SoF) detection on both transmit and receive paths, enabling precise packet boundary identification for hardware timestamping in TSN-compliant systems. This feature operates independently of MAC-layer processing and is documented in Section 6.16 of the DP83867IRPAPR datasheet (SNLS484J).
What MAC interfaces does DP83867IRPAPR support?
DP83867IRPAPR supports MII, GMII, and RGMII MAC interfaces simultaneously - enabled by its HTQFP-64 package pinout. Unlike the RGZ variant, the PAP package provides full pin access for all three standards, allowing system designers to retain hardware flexibility or migrate between MAC generations without PCB revision.
How is ESD protection implemented on DP83867IRPAPR?
DP83867IRPAPR exceeds IEC 61000-4-2 Level 4 with ±8 kV contact discharge on MDI pins, achieved via on-die robust clamping structures and optimized bond-wire routing. This eliminates the need for external TVS diodes in most industrial installations, reducing BOM cost and PCB area while maintaining compliance with EN61000-6-2 immunity requirements.
Can DP83867IRPAPR operate with a 1.8 V I/O supply?
Yes, DP83867IRPAPR supports configurable I/O voltage of 1.8 V (±5%), 2.5 V (±5%), or 3.3 V (±5%) on VDDIO pins, verified per Section 6.3 of the datasheet. This allows direct interfacing with low-voltage FPGAs and SoCs without level-shifting circuitry, provided all VDDIO pins are supplied at the same selected voltage and decoupled with 1 µF + 0.1 µF capacitors.
