DP83867IRPAPR

Controllers Overview

The DP83867IRPAPR is a Gigabit Ethernet Physical Layer (PHY) transceiver manufactured by Texas Instruments. It supports 10BASE-Te, 100BASE-TX, and 1000BASE-T standards over twisted-pair media. The device integrates the PMD sublayer and connects to MACs via GMII, MII, or RGMII interfaces. It operates with supply voltages of 1.1V and 2.5V, drawing a maximum current of 157mA. The component functions within an industrial temperature range of -40°C to +85°C and is housed in a 64-pin HTQFP package measuring 10x10mm.

Controllers Feature Summary

• Supports Time-Sensitive Networking (TSN) standards for deterministic communication
• Provides enhanced electrostatic discharge (ESD) protection exceeding IEC 61000-4-2 levels
• Integrates IEEE 1588 start-of-frame detection for precise timestamping
• Features ultra-low latency on the RGMII interface

Controllers Applications

• Industrial factory automation systems
• Motor drive controllers
• Wired and wireless communication infrastructure
• Test and measurement equipment

Controllers Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging when sourcing. Confirm the operating voltage requirements match the system design, as the device requires both 1.1V and 2.5V supplies. Ensure compatibility with the intended MAC interface, specifically RGMII or SGMII, before procurement.

Controllers Selection Notes

Select this component for applications requiring robust ESD protection and TSN compliance. The HTQFP-64 package is suitable for designs prioritizing thermal performance and interface flexibility. Consider the DP83867IRRGZR variant if a smaller VQFN-48 footprint is required, noting the interface differences between packages.

Controllers Part Context

This part belongs to the DP83867IR family of Gigabit Ethernet PHYs from Texas Instruments. It shares core specifications with the DP83867IRPAPT, differing primarily in the reel packaging configuration indicated by the 'R' suffix. The series is designed for industrial environments requiring high reliability and low power consumption.

Controllers Replacement Considerations

The DP83867IRPAPT is a direct functional equivalent with identical electrical characteristics, differing only in bulk packaging. The DP83867IRRGZR offers a pin-compatible alternative in a VQFN-48 package, though it lacks MII/GMII support due to form factor constraints.
