Universal ethernet PHY
Ethernet PHY is required in every microcontroller application which uses ethernet interface. It consists of RJ45 connector, transformers and PHY controller, which is analog circuit – interface between transformers and ethernet controller in microcontroller.
Circuit is divided in two PCB to keep it simple and single-sided. It connects via 20 pads (2,54mm raster) in dual row. Ethernet cables are usually stiff. Dual-in-line style of this module provides better mechanical rigidity.
Universal ethernet PHY module
Module assembly is simple: first solder all SMT components. Solder ethernet connector to smaller board. Finally, solder both boards together.

True; but not necessarily an *external* PHY – note that some microcontrollers do have a built-in, on-chip PHY:

could you provide me the altium library RJ45 that you used in that project .I will be grateful to you .
Thank you
Here’s the lib (pcb and sch).
Thank you very much
