Notes to
(1) 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
(2) The VCO frequency reported by the Quartus II software in the PLL summary section of the compilation report takes into consideration the VCO
(3) This specification is limited by the lower of the two: I/O F
(4) A high input jitter directly affects the PLL output jitter. To have low PLL output clock jitter, you must provide a clean clock source that is less
(5) F
(6) Peak-to-peak jitter with a probability level of 10
(7) The cascaded PLL specification is only applicable with the following condition:
(8) High bandwidth PLL settings are not supported in external feedback mode.
(9) External memory interface clock output jitter specifications use a different measurement method, which is available in
