PLL Specifications
PLL specifications are for Intel® Cyclone® 10 LP devices operating in the commercial junction temperature range (0°C to 85°C), the industrial junction temperature range (–40°C to 100°C), the extended industrial junction temperature range (–40°C to 125°C), and the automotive junction temperature range (–40°C to 125°C).

34 This parameter 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.
35 The VCO frequency reported by the Intel® Quartus® Prime 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.
36 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.
37 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.
38 With 100-MHz scanclk frequency.
39 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
40 PLL cascading is not supported for transceiver applications.
