    Clocking setting (CYUSB3014-BZXI)

      Hi~

         


      I used a clock frequency of 19.2Mhz which was referenced in the datasheet and set the Load Cap value to 12pF.
      However, video transmission / reception error via USB3.0 frequently occurs.
      I set the Load Cap value to a larger value of 27pF, which resulted in fewer errors.
      According to Datasheet, it should be set to 13.5pF, but now it is used as 27pF.
      1) Is there a problem when changing the crystal CO (CIRCUIT LOAD CAPACITANCE) value to a large value?
      In other words, does Side Effect occur?
      2) Is it possible to change CO value to S / W? In other words, is there a changeable register value?
