Hi Srikanth,

You have to refer to the pin connection guidelines of respective device.

  1. DIFFIO_TX_<> when used for differential channel it is output pin, If not used for differential signaling, these pins are available as user I/O pins(input or output).
  2. DIFFIO_RX_<> when used for differential channel it is input pin, If not used for differential signaling, these pins are available as user I/O pins(input or output).
  3. If not used for differential signaling, these pins are available as user I/O pins(input or output).
  4. FPLL_<> can be used for clock output.

Let me know if this has helped resolve the issue you are facing or if you need any further assistance.

Regards

Anand
