I am using 7 series GTX Ttransceiver.I have a question:
Is DRP clock must be provided?
can DRP_CLK_IN_P/N left floating(no connection)?

7 series GTX can operate without connecting DRPCLK.
However, in the example design of the transceiver wizard, the external input DRP_CLK is also used for sysclk and so on.
Therefore, DRP_CLK_IN_P / N may not be able to float.

> hi,Do you mean that I must use DRP clock if I use the transceiver wizard?
Yes. A local clock (DRP clock) is necessary for startup FSM and others.

Yes, The system clock input can be changed to single ended but it must still go through the BUFG.
