For less than $3.00 US it is worth looking and it specs out pretty
neat except for the top frequency (maybe it will push further with a
little help). Nice part to work with from a physical viewpoint.

The Si570 has about .4ps jitter at 40MHz, this part has 250ps jitter
at 40MHz, and it gets worse as you go higher. A clue is that the
jitter is so bad that it's rated in percent. There is no comparison
in term of phase noise between the two parts. The Si570 is way
cleaner in it's output.
