Frequency:
Please enquire if the frequency/stability
combination has been developed.
For part numbering use the first 4 characters of
the frequency in Hz i.e. 27MHz = 27000000Hz
so the code used in the part number is 2700. If
the frequency is 100MHz or higher then the
first 5 characters are used.
It is important to suffix the part number
