Sure. For example, from the AP Tech Note in the link of your post:

From ESS ES9038Q2M DAC chip datasheet:

Thank you. I suppose this jitter attenuation is implemented in most modern DACs. I just have a question to the comparison of Figure 21 with F.19 and F.20.

It states on page 14: Notice that the 5 kHz sidebands are attenuated compared with Figure 19, and the higher-frequency components resulting from the wide-band jitter are attenuated relative to Figure 20.

I can’t find any 5kHz sidebands in F.19 and the wide-band jitter in F.21 seems to be even higher than F.20. Any explanation?
