Hi all,

what is the need of USB 2.0 Transceiver Macrocell Interface (UTMI) ?

Thanks
 

Due to speed requirements analog features are required in the design and a PHY layer is being employed. This is made as a hard macro. And to make it reusable a standard interface has been defined. So anybody who does a USB design can just do the non-PHY portion compliant to UTMI interface and can buy an off the shelf USB PHY hardmacro and interface with it.

Its like saying the car manufacturer doesnt have to make the tyre also. Since the tyre is a standard you can just buy it and use on your car :)

Cheers,
eChipDesign.
