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.
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.
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.
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.
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.
