POWER-UP
Power-Up Sequence
The correct programming sequence for the ADF4360-9 after
power-up is as follows:
1. R Counter Latch
2. Control Latch
3. N Counter Latch
Initial Power-Up
Initial power-up refers to programming the part after the
application of voltage to the AVDD, DVDD, and VVCO pins. On
initial power-up, an interval is required between programming
the control latch and programming the N counter latch. This
interval is necessary to allow the transient behavior of the
ADF4360-9 during initial power-up to settle.
During initial power-up, a write to the control latch powers up
the part, and the bias currents of the VCO begin to settle. If
these currents have not settled to within 10% of their steady-
state value, and if the N counter latch is then programmed, the
VCO may not oscillate at the desired frequency, which does not
allow the band select logic to choose the correct frequency
band, and the ADF4360-9 may not achieve lock. If the
recommended interval is inserted, and the N counter latch is
programmed, the band select logic can choose the correct
frequency band, and the part locks to the correct frequency.
The duration of this interval is affected by the value of the
capacitor on the CN pin (Pin 14). This capacitor is used to
reduce the close-in noise of the ADF4360-9 VCO. The
recommended value of this capacitor is 10 F. Using this
value requires an interval of ≥15 ms between the latching in
of the control latch bits and latching in of the N counter latch
bits. If a shorter delay is required, the capacitor can be reduced.
A slight phase noise penalty is incurred by this change, which is
further explained in Table 6.
