In some applications, crystal with frequencies other than 114.285 MHz may be used. Contact Silicon Labs for
details and a current list of crystal vendors and approved part numbers.
External reference (and crystal) frequency values should be avoided that result in an output frequency that is an
integer or near integer multiple of the reference frequency. See Appendix B for details.
Because the crystal is used as a jitter reference, rapid changes of the crystal temperature can temporarily disturb
the output phase and frequency. For example, it is recommended that the crystal not be placed close to a fan that
is being turned off and on. If a situation such as this is unavoidable, the crystal should be thermally isolated with an
insulating cover.
