I'm building a simple USB-C to DisplayPort + USB-A out adapter PCB. My hope was to start with the CCG1 Type-C To DisplayPort Reference and simply branch the USB 2.0 data lines. My question is, are DP and DM used by the CY7C65210 for anything other than programming? If so, my solution is simple... just run them through a DIP Switch so I can either program or access as USB 2.0. Would this work?

  • Can the USB 2.0 DP/DM lines be used independently (to communicate with a legacy USB device) while the SuperSpeed lines are carrying DisplayPort in Alt-Mode?

  • Are the DP/DM inputs to the CY7C65210 needed for run-time or are they for programming only?

Thank you!

Hi ,

>> CY7C65210 is not only for firmware updating, but also for Billboard. 

>> CY7C65210 is USB2.0 to I2C bridge. 

  • Can the USB 2.0 DP/DM lines be used independently (to communicate with a legacy USB device) while the SuperSpeed lines are carrying DisplayPort in Alt-Mode?
    >> Yes. But CY7C65210 can send command to CCG1 and control the CCG1 in same functions.
  • Are the DP/DM inputs to the CY7C65210 needed for run-time or are they for programming only?

>> Refer my comments on first question.

 

Best Regards,

Lisa
