SUGGESTED SELECTIONS FOR SPECIFIC CUSTOMER APPLICATIONS(Notes 1, 2)
Note 1.
600MHz < (XTAL x MSEL) < 1000MHz.
Note 2.
Where two settings provide the user with the identical desired frequency, the setting with the higher input reference frequency (and lower
feedback divider) will usually have lower output jitter. However, the reference input frequency, as well as the VCO frequency, must be kept
within their respective ranges.
