NOTES:
1
All values given are initial design targets and subject to change.
2
All internal registers retain data at 0 Hz.
3
“Loss of Reference Frequency” is the reference frequency detected internally, which transitions the PLL
into self clocked mode.
4
Self clocked mode frequency is the frequency that the PLL operates at when the reference frequency falls
below f
LOR
with default MFD/RFD settings.
5
This parameter is guaranteed by characterization before qualification rather than 100% tested.
6
Proper PC board layout procedures must be followed to achieve specifications.
7
This parameter is guaranteed by design rather than 100% tested.
