4.6 Crystal Oscillator (XTO) Selection

All parameters in the data sheet are validated with the XTO frequency 24.305 MHz. This frequency was identified as usable for the typical applicable RF bands. However, it is possible to select another XTO frequency according to the specified parameter in the data sheet. If using another XTO frequency, verify and validate the following parameters:

  • XTO harmonic influences to the RF
  • System timings
  • Interface timings
  • Start-up behavior (in case of using other parameter or form factor)

For more details on how to calculate influences of the specified XTO frequency, refer to the AN3716_UHF_CrystalSelection Application Note.
