User IO pin vs PLL_CLKOUT0N pin. Can I output a clock on user IO?
- 7 years ago
The clkout is a dedicated path from the PLL to output pin. In zero delay buffer mode, the delay by the output pin is compensated. https://www.intel.com/content/www/us/en/programmable/documentation/mcn1401782837027.html#mcn1401869677350
The fitter allows your PLL to output to user io pin via global routing.
Will you get better performance? To find out, you will need to analyze timing given the PLL compensation mode and routing to the clkout pin.
