I just read the article "Aperture Uncertainty and ADC System Performance". It states in this article:
For example, consider the case of sampling an IF of 250 MHz. At that speed, even 1 ps of aperture jitter can limit any ADC’s SNR to only 56 dB, while for the same conditions, the phase uncertainty error is only 0.09 degrees rms based on a 4 ns period.
As far as I understand it is emphasized that the amplitude error is sensitive to the jitter but the phase error is not. Is it correct?
