This specification is limited in the Quartus II software by the I/O maximum frequency. The maximum I/O frequency is different for each I/O
standard.
The VCO frequency reported by the Quartus II software in the PLL Usage Summary section of the compilation report takes into consideration the
VCO post-scale counter K value. Therefore, if the counter K has a value of 2, the frequency reported can be lower than the fVCO specification.
