• Crystal
• External
In external clock mode, it is possible to run the chip directly from an external clock source without enabling the PLL.
Loss of reference frequency is the reference frequency detected internally that transitions the PLL into self-clocked mode.
Self-clocked mode frequency is the frequency that the PLL operates at when the reference frequency falls below f
default MFD/RFD settings.
This parameter is characterized before qualification rather than 100% tested.
Proper PC board layout procedures must be followed to achieve specifications.
All internal registers retain data at 0 Hz.
