2.3.10. Spread-Spectrum Clocking

The Intel® MAX® 10 devices allow a spread-spectrum input with typical modulation frequencies. However, the device cannot automatically detect that the input is a spread-spectrum signal. Instead, the input signal looks like deterministic jitter at the input of the PLL.

The Intel® MAX® 10 PLLs can track a spread-spectrum input clock if the input signal meets the following conditions:

  • The input signal is within the input jitter tolerance specifications.
  • The modulation frequency of the input clock is below the PLL bandwidth as specified in the Fitter report.

Intel® MAX® 10 devices cannot generate spread-spectrum signals internally. You must generate the spread-spectrum signals externally.
