This parameter is timing analyzed by the Quartus II software because the scanclk and scandata ports can be
driven by the logic array.

When using the spread-spectrum feature, the minimum VCO frequency is 500 MHz. The maximum VCO
frequency is determined by the speed grade selected.
Lock time is a function of PLL configuration and may be significantly faster depending on bandwidth settings or
feedback counter change increment.
