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 Table 1 Stability (ppm)
