Table 5-6 Jitter Value in case of 451.584 MHz Source Clock describes jitter values in various sampling clocks generated by divide by 2.
The intermediate clock, i.e. 98.304 MHz, corresponds to 1,024fs for 96KHz sampling.
jitter will disappear when it reaches to 32fs for 96KHz sampling (32fs = 3.072MHz).
sampling.
As jitter exists 64fs for 96KHz sampling, it may affect total harmonic distortion.
In case of Source Clock=338.688 MHz mode, mdgen_32_147 generates 73.728 MHz, which corresponds to 768fs for 96KHz sampling.
It has certain level of jitter up to 8fs for 96KHz sampling.
