Product details
Overview
DP83822IRHBR 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/100BASE-FX/10BASE-Te), operates from –40°C to 125°C, consumes <120mW at 1.8V AVD, and interfaces via RGMII/RMII/MII with programmable termination impedance.
For engineers reviewing the DP83822IRHBR datasheet, DP83822IRHBR pinout, DP83822IRHBR application, or DP83822IRHBR equivalent, this page delivers verified technical context, real-world interface timing constraints, industrial ESD/EFT immunity specs, power architecture options, and validated alternative PHYs for Profinet, motor drive, and grid infrastructure designs.
Technical Context
The DP83822IRHBR implements a full IEEE 802.3u-compliant PHY layer with integrated PMD for twisted-pair (10/100BASE-TX) and fiber (100BASE-FX) media, supporting auto-negotiation, Auto-MDIX in forced modes, and start-of-frame detection for IEEE 1588 timestamping. Its analog front-end includes differential TD_P/TD_M and RD_P/RD_M drivers/receivers with configurable swing and symmetry.
It features three MAC interface modes-MII (25/2.5MHz clock), RMII (50/25MHz reference), and RGMII (25/2.5MHz clock with built-in 1.8ns input skew compensation)-all sharing a single register map accessed via MDIO/MDC. Power management includes EEE (802.3az), WoL magic packet detection, and programmable energy-saving modes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 10/100Mbps Ethernet PHY applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DP83822H | Same pinout, identical electrical specs, but rated for –40°C to 125°C (no 'I' suffix = industrial temp grade); DP83822IRHBR is functionally identical. | No difference - DP83822IRHBR *is* the industrial-grade variant; 'IRHBR' denotes RHB package + industrial temp + tape-and-reel. | Select DP83822IRHBR when sourcing the production-ready industrial-grade version with full traceability and TI's extended warranty. |
| TLK106L | Legacy 10/100 PHY; lacks EEE, WoL, cable diagnostics, and RGMII skew compensation; lower ESD (±4kV HBM vs. ±8kV IEC). | Suitable only for non-real-time, non-harsh environments (e.g., office equipment); cannot replace DP83822IRHBR in Profinet or motor drive systems. | Choose TLK106L only for cost-sensitive, low-risk applications where industrial robustness and IEEE 1588 support are unnecessary. |
Compared with DP83822H, DP83822IRHBR offers identical performance and qualification - the suffix denotes packaging and ordering format, not functional divergence. Against TLK106L, DP83822IRHBR adds critical industrial features: EEE, rapid link-down, cable diagnostics, and ±8kV IEC ESD, making it essential for real-time and harsh-environment deployments.

FAQ
What is the operating temperature range of the DP83822IRHBR?
The DP83822IRHBR is rated for –40°C to 125°C ambient operation, qualifying it for extended industrial environments such as motor drives, grid substations, and factory-floor robotics. This range is confirmed in TI's SNLS505H datasheet Section 6.3 and applies to the 'H' and 'HF' variants - DP83822IRHBR falls under the industrial-grade 'H' temperature specification.
Does the DP83822IRHBR support both copper and fiber media?
Yes, the DP83822IRHBR supports 100BASE-TX (copper twisted-pair) and 100BASE-FX (fiber optic) physical layers. Its RD_P/RD_M and TD_P/TD_M pins can be configured for either medium, and the device includes Signal Detect functionality on LED_1/GPIO1 for 100BASE-FX mode. Fiber support is explicitly listed in the Device Comparison Table (Section 4) for DP83822HF and DP83822IF variants.
What MAC interfaces does the DP83822IRHBR support, and how are they selected?
The DP83822IRHBR supports MII, RMII, and RGMII MAC interfaces, selected via hardware strapping pins (e.g., RX_DV, CRS, COL) during power-up. Configuration details are in Section 5.2 of the datasheet. RGMII mode enables built-in 1.8ns input skew compensation, easing timing closure on high-speed traces - a key advantage over basic MII implementations.
How does the DP83822IRHBR implement Energy Efficient Ethernet (EEE)?
The DP83822IRHBR complies with IEEE 802.3az EEE, entering low-power idle (LPI) mode during packet gaps while maintaining link synchronization. LPI entry/exit is controlled via MDIO register access (e.g., register 0x0010). This reduces dynamic power by up to 50% in bursty traffic scenarios common in industrial monitoring and control applications - verified in TI's power characterization data.
What diagnostic capabilities does the DP83822IRHBR provide for field maintenance?
The DP83822IRHBR integrates cable diagnostics to detect open circuits, short circuits, and cable length (up to 120m) on the MDI pair; built-in self-test (BIST) verifies internal logic and analog paths; and digital/analog loopback modes enable isolation of PHY vs. MAC issues. These tools are accessible via MDIO registers and require no external test equipment - directly supporting predictive maintenance in remote installations.
