(53)
The VCO frequency reported by the Intel Quartus Prime software takes into consideration the VCO post divider value. Therefore, if the
VCO post divider value is 2, the frequency reported can be lower than the fVCO specification.
(54)
(55)
This specification is limited by the lower of the two: I/O fMAX or FOUT of the PLL.
High bandwidth PLL settings are not supported in external feedback mode.
