DP83867ERGZR

Controllers Overview

The DP83867ERGZR is a Gigabit Ethernet Physical Layer Transceiver manufactured by Texas Instruments. It supports 10/100/1000 Base-TX standards and operates within an extended industrial temperature range of -40°C to +105°C. The device utilizes a 48-VQFN (7x7 mm) package with exposed pad for surface mount installation. Key interface options include RGMII and SGMII, facilitating flexible integration with host MACs. Supply voltages are specified at 1.1V and 2.5V. This component is designed for robust performance in demanding networking environments.

Controllers Feature Summary

• Supports full-duplex and half-duplex operation across 10/100/1000 Mbps speeds
• Integrated physical layer controller with RGMII and SGMII interface compatibility
• Extended operating temperature range suitable for industrial applications

Controllers Applications

• Industrial networking equipment requiring extended temperature stability
• Gigabit Ethernet switches and routers
• Network interface cards and embedded communication systems

Controllers Procurement Notes

Verify the specific suffix ZR indicates the reel packaging configuration when sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Ensure the 48-VQFN footprint matches the design layout. Check for any recent product change notices regarding material composition or assembly location updates from Texas Instruments.

Controllers Selection Notes

Select this model when an extended temperature range up to 105°C is required compared to commercial variants. Choose the VQFN package for space-constrained designs needing a compact form factor. Verify that the host system supports either RGMII or SGMII interfaces as defined by the datasheet specifications. Consider power consumption profiles relative to the 1.1V and 2.5V supply rails during system architecture planning.

Controllers Part Context

This part belongs to the DP83867 family of Gigabit Ethernet PHY transceivers from Texas Instruments. It shares core functionality with models like the DP83867IR but differs in package type and operating temperature range. The ERGZR variant specifically targets industrial applications requiring higher thermal tolerance than standard commercial parts.

Controllers Replacement Considerations

Direct substitutes include other DP83867 family members such as DP83867IRPAPT for HTQFP-64 packages or DP83867ERGZTG4 for different QFN configurations. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
