Product details
Overview
DP83822HRHBR from Texas Instruments is a robust, low-power 10/100Mbps Ethernet physical layer transceiver designed for industrial environments. It supports IEEE 802.3u (100BASE-TX/10BASE-Te), operates from –40°C to 125°C, delivers <120mW at 1.8V AVD, and integrates RGMII/RMII/MII MAC interfaces with programmable termination impedance.
For engineers reviewing the DP83822HRHBR datasheet, DP83822HRHBR pinout, DP83822HRHBR application, or DP83822HRHBR equivalent, key selection criteria include its IEC 61000-4-2 ±8kV contact ESD rating, Energy Efficient Ethernet (IEEE 802.3az) support, Wake-on-LAN capability, cable diagnostics, and pin-to-pin upgrade path from TLK105/TLK106 family PHYs in harsh industrial Ethernet systems.
Technical Context
The DP83822HRHBR implements a full IEEE 802.3u-compliant PHY layer with automatic media detection for 10BASE-Te, 100BASE-TX, and 100BASE-FX modes. Its differential TD_P/TD_M and RD_P/RD_M interfaces support configurable PMD signaling, while integrated start-of-frame detection enables precise IEEE 1588 timestamping.
It features three MAC interface options-RGMII (25MHz clock input), RMII (50MHz/25MHz reference), and MII-with hardware-strapped or register-configurable I/O voltage support (1.8V/2.5V/3.3V) and programmable termination impedance. Power management includes EEE, WoL, and multiple software-controllable energy-saving modes.
Key Specifications

FAQ
What is the operating temperature range of the DP83822HRHBR?
The DP83822HRHBR is rated for –40°C to 125°C ambient operation, validated per manufacturer specifications for extended industrial use. This range applies to all functional modes including 100BASE-FX, RGMII, and EEE operation. The device's thermal design (RθJA = 41.0°C/W) and internal thermal protection ensure reliable performance under continuous load in unventilated enclosures. DP83822HRHBR maintains full IEEE 802.3u compliance across this entire range.
Does the DP83822HRHBR support fiber optic interfaces?
Yes, the DP83822HRHBR supports 100BASE-FX operation through its differential RD_P/RD_M and TD_P/TD_M pins, enabling connection to external fiber optic transceivers. It meets IEEE 802.3u 100BASE-FX electrical specifications-including 0.9–1.1Vpk-pk output swing and 0.22–1.8Vpk-pk input sensitivity-and includes signal detect functionality on LED_1/GPIO1 for optical link monitoring. DP83822HRHBR requires no external level-shifting or biasing for standard 100BASE-FX implementations.
What MAC interfaces does the DP83822HRHBR support?
The DP83822HRHBR supports three standardized MAC interfaces: RGMII (reduced gigabit media-independent), RMII (reduced media-independent), and MII (media-independent). Each interface is selectable via hardware strapping or register configuration. RGMII uses source-synchronous 25MHz/2.5MHz clocks with sub-2ns data-to-clock skew; RMII supports 50MHz/25MHz XI reference; MII provides full 4-bit nibble-wide parallel interface. DP83822HRHBR also supports programmable I/O voltage (1.8V/2.5V/3.3V) and termination impedance per interface.
How does the DP83822HRHBR implement Energy Efficient Ethernet (EEE)?
The DP83822HRHBR implements IEEE 802.3az Energy Efficient Ethernet via hardware-accelerated low-power idle (LPI) mode entry/exit, triggered automatically during packet gaps without MAC-layer intervention. It achieves <120mW total power at 1.8V AVD in active operation and further reduces consumption during LPI. The PHY maintains full link integrity and recovers in <4us upon traffic resumption. DP83822HRHBR's EEE implementation is fully interoperable with standard-compliant switches and controllers-no firmware modifications required.
Is the DP83822HRHBR pin-compatible with earlier TI PHYs?
Yes, the DP83822HRHBR is pin-to-pin compatible with the TLK105, TLK106, TLK105L, and TLK106L 10/100Mbps PHYs in the same 32-pin VQFN (RHB) package. This enables direct hardware upgrades without PCB redesign. Key enhancements include ±8kV IEC 61000-4-2 ESD rating (vs. ±4kV), integrated cable diagnostics, EEE support, and improved thermal performance. DP83822HRHBR retains identical pin functions, power sequencing, and register map structure for seamless migration.
