2. With FM; the value does not include a possible +2% modulation
3. “Loss of Reference Frequency” window is the reference frequency range outside of which the FMPLL is in self clocked
mode.
4. Self clocked mode frequency is the frequency that the FMPLL operates at when the reference frequency falls outside the
f_LOR window.
5.

MHz.
6. This value is determined by the crystal manufacturer and board design. For 4 MHz to 20 MHz crystals specified for this
FMPLL, load capacitors should not exceed these limits.
7. This specification applies to the period required for the FMPLL to relock after changing the MFD frequency control bits in
the synthesizer control register (SYNCR).
8. This value is determined by the crystal manufacturer and board design.
