DP83867IRRGZT

Controllers Overview

The DP83867IRRGZT is a robust, high-immunity 10/100/1000 Ethernet Physical Layer (PHY) transceiver manufactured by Texas Instruments. It supports 10BASE-Te, 100BASE-TX, and 1000BASE-T protocols with integrated PMD sublayer functionality. The device operates within an industrial temperature range of -40°C to +85°C and utilizes a 48-pin VQFN package measuring 7x7 mm. Key electrical parameters include a maximum data rate of 1 Gbps, supply voltages of 1.1V, 1.8V, 2.5V, and 3.3V, and a maximum supply current of 137 mA. It features ultra-low RGMII latency with transmit delay under 90ns and receive delay options.

Controllers Feature Summary

• Provides enhanced electromagnetic interference immunity exceeding IEC 61000-4-2 standards for harsh industrial environments
• Supports Time-Sensitive Networking (TSN) and IEEE 1588 precision time protocol with start-of-frame detection
• Integrates configurable MAC interfaces including GMII, MII, and RGMII with programmable terminal impedance
• Includes built-in cable diagnostics and LAN Wake-Up capabilities for system power management

Controllers Applications

• Industrial factory automation and motor drive systems
• Fieldbus-enabled embedded computing platforms
• Wired and wireless communication infrastructure equipment

Controllers Procurement Notes

Verify the specific suffix 'TG4' or standard 'RGZT' against the latest TI datasheet revision to ensure correct temperature grade and packaging configuration. Confirm moisture sensitivity level requirements during storage and handling. Check for active status and lead times as availability may fluctuate based on manufacturing cycles.

Controllers Selection Notes

Select this component when high EMI immunity and deterministic latency are critical for network synchronization. Ensure the design accommodates the 48-VQFN thermal pad requirements for adequate heat dissipation. Verify that the host MAC interface matches the supported RGMII, GMII, or MII modes without requiring additional level shifters if voltage domains differ.

Controllers Part Context

This part belongs to the DP83867 family of Gigabit Ethernet PHYs, designed for robust connectivity in noisy environments. It serves as a direct replacement for previous generations like the DP83865 in applications demanding improved signal integrity and lower power consumption while maintaining full IEEE 802.3 compliance.

Controllers Replacement Considerations

Direct substitutes include the DP83867CRRGZT for commercial temperature ranges and the DP83867ERGZT for extended ruggedized variants. Cross-reference pinouts and register maps to ensure compatibility with existing firmware drivers before swapping components.
