Occasional ContributorStratix 10 IOPLL Frequency range
Hi, I am trying to create 512KHz from 200 MHZ reference clock using IOPLL. But the actual frequency generated is 1.176471MHZ. I would like to know is there a way to generate 512KHz using pll for s...

Frequent ContributorHi @SK VA
You wont be able to generate 512kHz. If you refer to the datasheet. the VCOmin is 600Mhz. The max C-counter is 510. If you take 600MHZ/510=1.176471MHZ...this is the minimum frequency that can output from the IOPLL.
See datasheet; https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/stratix-10/s10_datasheet.pdf#page=28
