Product details

Ethernet PHY with dual interface flexibility

The Texas Instruments DP83822IFRHBT is a single-port Ethernet PHY transceiver supporting both MII and RMII interfaces, housed in a 32-VQFN (5x5) package with exposed thermal pad.

Package and thermal design note

The 32-VQFN (5x5 mm) with exposed pad requires a thermal via array under the paddle to conduct heat into the PCB ground plane.

Lifecycle and sourcing posture

The DP83822IFRHBT carries an active lifecycle status with ROHS3 compliance. The active status means no LTB risk for the next several years of production, though PCN monitoring is always recommended for any Ethernet PHY used in a qualified design.

Frequently asked questions

Is DP83822IFRHBT compatible with both MII and RMII interfaces?

Yes, the DP83822IFRHBT supports both MII and RMII interfaces. RMII uses 6 signals versus MII's 12, reducing PCB routing complexity and layer count. The same device can serve designs targeting either MAC interface type.

Does DP83822IFRHBT have an equivalent or cross-reference?

The DP83822IFRHBT is a specific ordering code variant of the DP83822 family. The 'RHB' suffix denotes the 32-VQFN package and 'T' indicates tape-and-reel packaging. The base DP83822I device shares the same core PHY functionality but may differ in package or temperature grade — verify pin compatibility against the specific variant you are replacing.

What package does DP83822IFRHBT come in?

The DP83822IFRHBT is supplied in a 32-VFQFN exposed pad package, also designated as 32-VQFN (5x5 mm). It is available in Tape & Reel (TR) or Cut Tape (CT) options for production or prototyping quantities.
