Does tx_outclock of ALTLVDS_TX have to be connected to dedicated clock output pin?

I use Stratix V/ Arria10 Device. I made serdes with ALTLVDS_TX. I want output tx_outclock of ​ALTLVDS_TX to pin. Does tx_outclock of ALTLVDS_TX have to be connected to dedicated clock output pin?...

Hi ,

I would recommend you to use dedicated clock pins for jitter performance. The jitter level is low for the dedicated clock pins comparing to regular IO.

And I also recommend you to do the compilation on Quartus to make sure that the pins are compact with IO assignments
