DP83867IRPAPT

Controllers Overview

The DP83867IRPAPT is a Gigabit Ethernet PHY transceiver from Texas Instruments, housed in a 64-pin HTQFP package. It supports IEEE 802.3 standards including 10BASE-Te, 100BASE-TX, and 1000BASE-T. The device operates with supply voltages of 1.1V and 2.5V, drawing a maximum current of 157 mA. It functions within a temperature range of -40°C to +85°C. Key interfaces include GMII, MII, and RGMII. The component integrates PMD sublayer functionality and provides ESD protection exceeding 8kV IEC 61000-4-2.

Controllers Feature Summary

• Supports Time-Sensitive Networking (TSN) standards for deterministic communication
• Integrates IEEE 1588 start-of-frame detection for precise timestamping
• Features ultra-low RGMII latency with configurable TX and RX delay modes
• Provides LAN Wake-Up (WoL) capability to reduce system power consumption

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 RPAPT corresponds to the 64-pin HTQFP package configuration. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for your assembly process. Ensure the ordering part number matches the exact voltage and interface specifications required by your design.

Controllers Selection Notes

Select this component when a robust Gigabit PHY with TSN support is required. The HTQFP package is suitable for applications needing GMII/MII/RGMII connectivity. Consider the 157 mA max current draw for power budget calculations. Verify compatibility with external magnetics regarding insertion loss and open-circuit inductance values.

Controllers Part Context

This part belongs to the DP83867 family of Gigabit Ethernet PHY transceivers. It shares core functionalities with variants like the DP83867ISRGZR but differs in packaging. The IR designation indicates industrial temperature rating capabilities. It serves as a physical layer solution for connecting MAC layers to twisted-pair media.

Controllers Replacement Considerations

The DP83867ISRGZR is a pin-compatible alternative in a 48-VQFN package. Verify interface compatibility and thermal performance differences between the HTQFP and VQFN packages before substitution.
