Thank you all for advice.
Yes i know that just frequency is not enough for ordering a crystal.
The only problem is that in general the minimum lot is 10 pieces!
The need is for a DDS with AD9951. At that freq the microcode to drive the
DDS will be very simple: i'll have just to enter the freq and shift a
register 4 time.
No multiply or division that usually are slow algoritm. And resolution will
be 1Hz.
Thank again.

I'm looking for a producer that can make 2 pieces of quartz at 268.435 MHz
(or 134.217MHz).
Any advice please?
Thanks.
Mauro
