KL0x / KL2x clock drift

Question asked by yoramshacham on Dec 9, 2015



I require to have an accurate clock for my application.

Looking at the 48MHz High Accuracy Clock (HIRC48M) spec, I see the Total Deviation and Period Jitter (RMS).

  1. How do I factor these parameters in order to calculate what will be the clock divination after 24 hours for example.
  2. Reading around I've seen that Period Jitter is calculated over a determined large number of cycles.
    Any idea the number of cycles used to come up with the figures shown in the KL03 period jitter table (34 psec typical and 150 psec max) ?
  3. Are there other factors involved in drift calculation I have to take into account?
