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.

FREF is fIN/N, specification applies when N = 1.
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 Memory Output Clock Jitter Specification for Cyclone V
Devices table.

This specification only covers fractional PLL for low bandwidth. The fVCO for fractional value range 0.20–0.80 must be ≥ 1200 MHz.
External memory interface clock output jitter specifications use a different measurement method, which are available in Memory
Output Clock Jitter Specification for Cyclone V Devices table.
