I've put together a circuit identical to that in National's Data Sheet.
I get a near to 48 MHz sine wave of about 200 mV out of both outputs.
This is with no input signals. I get this result with several different
chips. I tried on solderless breadboard and a perfboard. Upper side is a
ground plane where all capacitors are tied as short as possible.
I tried first with conventional components (wired) and then with SMT.
I tried also with a ground plane on the upper side where all capacitors
were tied as short as possible.
But all that without any result...
Any ideas?
Thanks!
P.S. sorry for my poor english ...
