Hardware Power-Up/Power-Down
If the ADF4360-2 is powered down via the hardware (using the
CE pin) and powered up again without any change to the N
counter register during power-down, the part locks at the
correct frequency because it is already in the correct frequency
band. The lock time depends on the value of capacitance on the
C
capacitance of 440 nF on this pin enables lock times of <600 μs.
The N counter value cannot be changed while it is in power-
down because it may not lock to the correct frequency on
power-up. If it is updated, the correct programming sequence
for the part after power-up is to the R counter latch, followed by
the control latch, and finally the N counter latch, with the
required interval between the control latch and N counter latch,
as described in the Initial Power-Up section.

Software Power-Up/Power-Down
If the ADF4360-2 is powered down via the software (using the
control latch) and powered up again without any change to the
N counter latch during power-down, the part locks at the
correct frequency because it is already in the correct frequency
band. The lock time depends on the value of capacitance on the
C
capacitance of 440 nF on this pin enables lock times of <600 μs.
The N counter value cannot be changed while the part is in
power-down because it may not lock to the correct frequency
on power-up. If it is updated, the correct programming
sequence for the parts after power-up is to the R counter latch,
followed by the control latch, and finally the N counter latch,
with the required interval between the control latch and N
counter latch, as described in the Initial Power-Up section.
