    UART & USB Clock

    yeffry.zakizon

      Hi,

         

      When using UART & USB, i must use IMO at 24Mhz to get USB clock 48Mhz, however this give me tolerance 4% and it's not accepted by UART which need at least 2% tolerance.

         

      Do i need to use XTAL in this case?

         

      Thanks
