HowdyWell more than what? I just used the Si570 as a handy example, I don't claim that it is the best one out there, but current clock synthesizers (which use sigma delta "dither" to interpolate between integers when dividing the clock back down) aren't nearly as bad as the older ones that simply used a (big) integer clock multiplier followed by an integer clock divider. Some might claim that specifically whitening the jitter might be a good idea.
Digital isolators have more bandwidth than standard optical isolators and that isolation might be more beneficial than no isolation if the down stream jitter attenuation is high enough. It's all tradeoffs.
I still really don't have any idea what was being described in your original post :)
