SiTime Oscillator Part Suffixes X & G


#1

On Oscillator parts from SiTime the “X” or “G” suffix on the end of a part is calling out a 250 piece reel. SiTime considers any reel that is less than 1,000 pieces custom and that is why you will not see this packaging suffix listed on the standard data sheet. The difference is the “X” suffix is a 12 or 16 mm width reel depending on the part and the “G” suffix is an 8mm width reel.

Below is an example part number breakdown from part SIT1533AI-H4-DCC-32.768G. As you can see they have call outs for “S” “D” and “E”, however since this part number comes on a 250 piece reel it is considered custom and the “G” does not appear on the data sheet. The following part numbers are the same part, however just on larger reels.
