Stratix10 E-tile how to use the nine reference clock

HI,

Your question is too generic. My best answer for you is to check out E-tile user guide doc chapter 4 that explained on E-tile refclk pins

• https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug_etile_xcvr_phy.pdf

Basically NativePHY IP support refclk pin switching up till 5 pins in one NativePHY design.

• Meaning you can connect different refclk pins to different clock frequency and switch between different refclk pins in actual application test later to support different data rate

Thanks.

Regards,
