Hi Mark --
Thanks! To clarify, when you say you've found "it" acceptable, you're
referring to the 5328?
What caught my eye about the 5351 was the three (or eight) outputs. My
idea was to build a board that would provide independent LO oscillators
for multiple VHF/UHF transverters. It looks like the 5328 has two
outputs, which is still useful but would require putting two or three of
them on the board. Which isn't the end of the world.
Thanks,
John

Sorry to hijack the thread, but the Si5351 looks interesting for another
project I'm working on. I know it specifies "low jitter" but has anyone
looked at the phase noise? Is it usable for RF applications?
Datasheet states jitter in the 40-70 ps range. That is not very good. If
you want something suitable for RF applications, look at the Si5328. It has
jitter on the order of 300fs.
I believe Leo Bodnar uses it in his GPSDOs and I can confirm the phase
noise and Allan Deviation others have found and it is suitable for me for
RF applications. It is not nearly as good as the Thunderbolt though. It
will generate almost any frequency you want.
