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,

As tx_outclock generated from a PLL, it is better to assign to a dedicated clock output pin for better jitter performance and clock specific routing inside the FPGA.
