1.
Considering operation with PLL not bypassed.
2.
All internal registers retain data at 0 Hz.
3.
“Loss of Reference Frequency” window is the reference frequency range outside of which the PLL is in self clocked mode.
4.
Self clocked mode frequency is the frequency that the PLL operates at when the reference frequency falls outside the fLOR
window.
