John:
All SMT OCXO's will either have a recommended PCB footprint in the spec
sheet
or will refer you to a recommended footprint in another document.
Some don't care about a ground plane under the part, some require it
with no crossing signals, some require an open thermal hole underneath
the oven. I have seen all three cases. As usual, it is suggested that you
read the [] manual.

Hello,
I was wondering if I could get some recommendations on surface mount OCXO's
vs. the traditional through hole.
I was also wondering on the board layout - if you found it necessary to
leave a thermal moat so to speak - and what worked best. Maybe the OCXO
has an internal air barrier that maybe would make this unnecessary - not
sure.
Your input and experience appreciated.
Thanks,
John Westmoreland
