Notes to Table 1–25:
(1) This table is applicable for general purpose PLLs and multipurpose PLLs.
(2) You must connect VCCD_PLL to VCCINT through the decoupling capacitor and ferrite bead.
(3) This parameter is limited in the Quartus II software by the I/O maximum frequency. The maximum I/O frequency is different for each I/O
standard.
(4) The VCO frequency reported by the Quartus II software in the PLL Summary section of the compilation report takes into consideration the VCO
post-scale counter K value. Therefore, if the counter K has a value of 2, the frequency reported can be lower than the fVCO specification.
(5) 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
than 200 ps.
(6) 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.
(7) With 100-MHz scanclk frequency.
(8) The cascaded PLLs specification is applicable only with the following conditions:
■ Upstream PLL—0.59 MHz Upstream PLL bandwidth < 1 MHz
■ Downstream PLL—Downstream PLL bandwidth > 2 MHz
(9) PLL cascading is not supported for transceiver applications.
