SiTime Part Number Generator

Not sure on where to start with a SiTime product? Maybe you have a partial part number and other specifications to put together the rest of the part number. If that is the case, you’re in luck. Take a look at the part number generator that SiTime has on their website here - SiTime Part Number Generator.

For instance, if you have the base part number of SiT1532, a -40 to 85 degree Celsius temperature range, and a DC-coupled output VOL or AC swing of 350mV, you can click those options to build the part number. The frequency appears to be a standard 32.768 KHz with this option as well as the package size of 1.5mm x 0.8mm. There are a few other options that will need to be filled out to generate the part number such as frequency stability (PPM), DC-coupled output VOH, AC- or DC-coupled receiver, and the amount of packaging you would like. Once you click the options that you are satisfied with, the part number will be generated to order as a SiTime part.

With the example above, and the options filled in on the part number generator, you would see something like this for a final part number: SiT1532AI-J4-AA3-32.768E. Once you have the part number, click the “Buy on Digi-Key” button under the part number. If the part number is not in our system, please check out the post on How to order custom SiTime Programmable Oscillators.
