DP83822HFRHBR

Specialized Overview

The DP83822HFRHBR is a robust, low-power 10/100-Mbps Ethernet Physical Layer Transceiver manufactured by Texas Instruments. It supports 10BASE-T and 100BASE-TX standards with full and half-duplex operation. The device operates on a single supply voltage ranging from 1.8 V to 3.45 V and functions within an extended temperature range of -40°C to +125°C. It integrates MII, RMII, and RGMII interfaces for host connectivity. Packaged in a 32-pin VQFN (5x5 mm) format, it includes features such as Wake-on-LAN, Energy-Efficient Ethernet, and cable diagnostics.

Specialized Feature Summary

• Integrated physical layer transceiver supporting 10/100 Mbps Ethernet standards
• Supports multiple host interfaces including MII, RMII, and RGMII
• Extended industrial temperature rating for harsh environments
• Includes energy-efficient and wake-on-lan capabilities

Specialized Applications

• Industrial EtherCAT slave devices
• Multi-protocol industrial Ethernet systems
• Fieldbus network nodes

Specialized Procurement Notes

Verify the specific suffix 'H' confirms the extended temperature range (-40°C to +125°C) required for your application environment. Confirm the 'FRHB' package code matches the VQFN-32 footprint specifications in your PCB design. Ensure power supply rails align with the 1.8V to 3.45V operating limits defined in the datasheet.

Specialized Selection Notes

Select this component when extended temperature operation is mandatory for industrial applications. Compare interface requirements against MII, RMII, or RGMII availability on the host processor. Evaluate power consumption constraints relative to the device's low-power architecture compared to standard commercial grade alternatives.

Specialized Part Context

This part belongs to the DP83822 family of Ethernet PHYs designed for cost-sensitive and space-constrained applications. It serves as a physical layer solution for connecting MAC controllers to twisted-pair copper cabling. The H variant specifically denotes the extended temperature grade suitable for demanding industrial settings.

Specialized Replacement Considerations

DP83822IRHBR: Commercial temperature grade version. TLK106LRHBT: Similar VQFN-32 package but different feature set and interface support.
