PLL - variable frequency input, constant output (Max10)

Hi,

https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/max-10/ug_m10_clkpll.pdf

as per above link, 2.3.12. Clock Switchover chapter talks about changing the input reference clock frequency (only 2 frequencies)

apart from that, you can use Asynchronous FIFO to work in a constant frequency.

In Asynchronous FIFO,

on the transmission side, write the data to Asynchronous FIFO with the constant frequency and Ethernet interface may read this data wrt the link clock and take it to next level. Otherway, in the receiver side.

With Regards,
