Num
All values given are initial design targets and subject to change.
All internal registers retain data at 0 Hz.
“Loss of Reference Frequency” is the reference frequency detected internally, which 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
This parameter is guaranteed by characterization before qualification rather than 100% tested.
Proper PC board layout procedures must be followed to achieve specifications.
This parameter is guaranteed by design rather than 100% tested.
