170 This specification is limited in the Intel® Quartus® Prime software by the I/O maximum frequency. The maximum I/O frequency is different for each I/O standard.
171 The VCO frequency reported by the Intel® Quartus® Prime software in the PLL Usage Summary section of the compilation report 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.
172 This specification is limited by the lower of the two: I/O fMAX or fOUT of the PLL.
173 High bandwidth PLL settings are not supported in external feedback mode.
174 A high input jitter directly affects the PLL output jitter. To have low PLL output clock jitter, you must provide a clean clock source with jitter < 120 ps.
175 The fREF is fIN/N specification applies when N = 1.
176 Peak-to-peak jitter with a probability level of 10–12 (14 sigma, 99.99999999974404% confidence level). The output jitter specification applies to the intrinsic jitter of the PLL, when an input jitter of 30 ps is applied. The external memory interface clock output jitter specifications use a different measurement method and are available in the Worst-Case DCD on Arria V GZ I/O Pins table.
177 This specification only covered fractional PLL for low bandwidth. The fVCO for fractional value range 0.20–0.80 must be ≥ 1200 MHz.
178 The external memory interface clock output jitter specifications use a different measurement method, which is available in the Memory Output Clock Jitter Specification for Arria V GZ Devices table.
179 This specification only covered fractional PLL for low bandwidth. The fVCO for fractional value range 0.05–0.95 must be ≥ 1000 MHz.
180 The cascaded PLL specification is only applicable with the following condition:
a. Upstream PLL: 0.59Mhz ≤ Upstream PLL BW < 1 MHz 
b. Downstream PLL: Downstream PLL BW > 2 MHz
